To find the athlete's salary for year 7 of the contract, apply a 4% annual increase to the previous year's salary starting from year 2. The athlete's salary for year 7 is approximately $3,836,192.
Explanation:To find the athlete's salary for year 7 of the contract, we need to calculate the annual increase for each year from year 2 to year 7 and apply it to the starting salary of $3,000,000 for year 1.
In year 2, the salary is 1.04 times the previous year's salary, so the salary for year 2 is $3,000,000 * 1.04 = $3,120,000.
In year 3, the salary is 1.04 times the previous year's salary, so the salary for year 3 is $3,120,000 * 1.04 = $3,244,800.
Following the same pattern, we can calculate the salaries for years 4, 5, 6, and 7:
In year 4: $3,244,800 * 1.04 = $3,379,392
In year 5: $3,379,392 * 1.04 = $3,523,027.68
In year 6: $3,523,027.68 * 1.04 = $3,675,348.11
In year 7: $3,675,348.11 * 1.04 = $3,836,191.72
Therefore, the athlete's salary for year 7 of the contract is approximately $3,836,192.
The athlete's salary for year 7 of the contract is $3,822,736.
To calculate the athlete's salary for year 7, we use the formula for compound interest, which is also applicable to salaries that increase annually at a fixed percentage. The formula is:
[tex]\[ A = P(1 + r)^n \][/tex]
Given that the initial salary (principal amount P is $3,000,000 and the annual increase rate r is 4% (or 0.04 as a decimal), we can calculate the salary for year 7 as follows:
[tex]\[ A = 3,000,000(1 + 0.04)^{7-1} \] \[ A = 3,000,000(1.04)^6 \] \\[ A = 3,000,000 \times 1.26530612 ](after calculating ( 1.04^6 \)) \\\\[A = 3,822,736 \][/tex]
(after rounding to the nearest dollar)
Therefore, the athlete's salary for year 7 of the contract, rounded to the nearest dollar, is $3,822,736.
A rectangle is inscribed in an equilateral triangle so that one side of the rectangle lies on the base of the triangle. Find the maximum area the rectangle can have when the triangle has side length 14 inches.
Answer:
A(max) = 42.43 in²
Dimensions:
a = 7 in
b = 6,06 in
Step-by-step explanation: See annex
Equilateral triangle side L = 14 in, internal angles all equal to 60°
Let A area of rectangle A = a*b
side b tan∠60° = √3 tan∠60° = b/x b = √3 * x
side a a = L - 2x a = 14 - 2x
A(x) = a*b A(x) = ( 14 - 2x ) * √3 * x
A(x) = 14*√3*x - 2√3 * x²
Taking derivatives both sides of the equation
A´(x) = 14√3 - 4√3*x
A´(x) = 0 ⇒ 14√3 - 4√3*x = 0 ⇒ 14 - 4x = 0 x = 14/4
x = 3,5 in
Then
a = 14 - 2x a = 14 - 7 a = 7 in
b = √3*3,5 b = *√3 *3,5 b = 6,06 in
A(max) = 7 *6,06
A(max) = 42.43 in²

FortyForty people purchase raffle tickets. Three winning tickets are selected at random. If first prize is $50005000, second prize is $45004500, and third prize is $500500, in how many different ways can the prizes be awarded?
To determine the number of different ways the prizes can be awarded, we need to use the concept of combinations.
Explanation:To determine the number of different ways the prizes can be awarded, we need to use the concept of combinations. Since there are 40 people purchasing raffle tickets, and 3 winning tickets are selected at random, we can find the number of ways the prizes can be awarded using the formula for combinations:
C(n, r) = n! / ((n-r)! * r!)
Where n is the total number of items and r is the number of items chosen at a time. In this case, n = 40 and r = 3:
C(40, 3) = 40! / ((40-3)! * 3!)
= 40! / (37! * 3!)
= (40 * 39 * 38) / (3 * 2 * 1)
= 9880
Therefore, there are 9,880 different ways the prizes can be awarded.
Please please help me with this
Answer:
Step-by-step explanation:
First find the equations of the lines, then fill in the proper inequality sign. The upper line has a y-intercept of 1 and a slope of 1/2, so the equation, in slope-intercept form is
[tex]y=\frac{1}{2}x+1[/tex]
Since the shading is below the line, the inequality sign is less than or equal to. The inequality, then, is
[tex]y\leq \frac{1}{2}x+1[/tex]
But the solutions are in standard form, so let's do that:
[tex]-\frac{1}{2}x+y\leq 1[/tex]
AND they do not like to lead with negatives, apparently, so let's change the signs and the way the inequality is facing, as well:
[tex]\frac{1}{2}x-y\geq -1[/tex]
Let's do the sae with the lower line. The equation, in slope-intercept form is
[tex]y=\frac{3}{2}x-3[/tex] since the slope is 3/2 and the y-intercept is -3. Now, since the shading is above the line, the inequality is greater than or equal to:
[tex]y\geq \frac{3}{2}x-3[/tex]
In standard form:
[tex]-\frac{3}{2}x+y\geq -3[/tex] and not leading with a negative gives us
[tex]\frac{3}{2}x-y\leq 3[/tex]
Those 2 solutions are in choice B, I do believe.

The previous triangular prism had a surface area of 288 square units. What happens to the surface area of your prism when you double all four measurements?
If all four dimensions of triangular prism having surface area as 288 is doubled than new surface area will be four times than the initial prism that is 1152 square unit.
Solution:Given that
Surface area of a triangular prism = 288 square unit
Need to evaluate new surface area if all four measurement of triangular prism is double.
Relation between surface area and the four dimensions of the triangular prism is given by following formula
Surface Area of triangular prism = bh + 2ls + lb
Where h is height of the prism , b is length of base of the prim , l is length of the prism and s is side length of the prism.
Given that Area of triangular prism = 288 square unit
=> bh + 2ls +lb = 288
Doubling the four dimensions means replace b by 2b, l by 2l , s by 2s and h by 2h in formula of Surface area of triangular prism.
[tex]\text { We get Surface area of new triangular prism }=2 b \times 2 h+2 \times 2 l \times 2 s+2 l \times 2 b[/tex]
[tex]\begin{array}{l}{=4 \times b h+4 \times 2 l s+4 \times l b} \\\\ {=4(b h+2 l s+l b)}\end{array}[/tex]
=> Surface area of new triangular prism = 4 (bh + 2ls +lb)
=> Surface area of new triangular prism = 4 x 288 = 1152 square unit.
Hence we can conclude that if all four dimensions of triangular prism having surface area as 288 is doubled than new surface area will be four times than the initial prism that is 1152 square unit.
Answer: C, the surface area increases by 4 times
Step-by-step explanation:
The late fee for library books is $2.00 plus 15 cents each day for a book that is late.If Maria's fee for a late book was $3.20,write and solve a linear equation to find many days late the book was.
First we will subtract $2 from $3.2 since that is late fee to get $1.2.
Now we divide $1.2 by $0.15 to get number of cents hence 8 days.
The answer is Maria is 8 days too late to hand over the book.
Hope this helps.
The linear equation is 3.20 = 2.00 + 0.15*x. Hence, Maria's book was 8 days late.
To find out how many days Maria's book was late, we need to set up a linear equation using the given information.
The total late fee equation is given by:
Late Fee = 2.00 + 0.15*x
Where $2.00 is the base fee, and 0.15 dollars is the additional late fee per day. Since Maria's total fee was $3.20, we can set up the equation as follows:
3.20 = 2.00 + 0.15*x
Now, solve for x, which represents the number of days the book was late:
Subtract $2.00 from both sides:
3.20 - 2.00 = 0.15*x
Simplify the equation:
1.20 = 0.15*x
Divide both sides by 0.15 to isolate x:
x = 1.20 / 0.15
Calculate the result:
x = 8
So, Maria's book was 8 days late.
A baseball player strikes out three times for every two hits he gets if the player strikes out 15 times how many hits does he get if the player gets 46 hit how many times does he strike out
The player will get 10 hits for 15 times strikes out.
The player will strike out 69 times for 46 hits.
Step-by-step explanation:
Given,
Ratio of strike out to hits = 3:2
Condition 1: If the player gets 15 strikes out;
Let,
x be the hits for 15 times strikes out.
Using proportion;
Strike out : hit :: strike out : hit

[tex]15*2=3*x\\3x=30[/tex]
Dividing both sides by 3;
[tex]\frac{3x}{3}=\frac{30}{3}\\x=10[/tex]
The player will get 10 hits for 15 times strikes out.
Condition 2: if the player gets 46 hits
Let,
y be the strikes out.
Using proportion,
Strike out : hit :: strike out : hit
[tex]3:2::y:46[/tex]
Product of mean = Product of extreme
[tex]2*y=46*3\\2y=138[/tex]
Dividing both sides by 2;
[tex]\frac{2y}{2}=\frac{138}{2}\\y=69[/tex]
The player will strike out 69 times for 46 hits.

Triangle $ABC$ has sides of $6$ units, $8$ units, and $10$ units. The width of a rectangle, whose area is equal to the area of the triangle, is $4$ units. What is the perimeter of this rectangle, in units
Answer:
20
Step-by-step explanation:
Given that the area of the rectangle is equal to that of the triangle
Area of triangle $ABC$
= 1/2 (bh)
Given that the sides of the triangle are $6$ units, $8$ units, and $10$ units,
The base and the heights are $6$ units and $8$ units. The $10$ units is the hypotenuse
From Pythagoras theorem,
6^2 + 8^2 = 10^2
Therefore, area of triangle
=1/2 (6 × 8)
= $24$ units^2
Area of rectangle = L × W
Where L = Length, W = Width
Area of the rectangle = area of triangle
L × 4 = 24
L= 24/4
L = $6$ Units
Perimeter of rectangle
=2 (L + B)
= 2(6 + 4)
= $20$ Units
Answer:
20
Step-by-step explanation:
We use the Pythagorean Theorem to verify that triangle $ABC$ is a right triangle, or we recognize that $(6,8,10)$ is a multiple of the Pythagorean triple $(3,4,5)$. The area of a right triangle is $\frac{1}{2}bh$ where $b$ and $h$ are the lengths of the two legs, so the area of triangle $ABC$ is $\frac{1}{2}(6)(8)=24$. If the area of the rectangle is $24$ square units and the width is $4$ units, then the length is $\frac{24}{4}=6$ units. That makes the perimeter $6+6+4+4=\boxed{20}$ units.

Answer:
Ik sorry but you can
Step-by-step explanation:
search in internet
The student needs to find the decryption exponent 'd' for the RSA algorithm by computing the modular multiplicative inverse of e modulo φ(n), and then use that to decrypt the message.
Explanation:The student is asking how to decrypt a message that was encrypted using the RSA algorithm. The given public key consists of n = 43 · 59 and e = 13, and the encrypted message is 0667 1947 0671. To decrypt the message, we need to find the private key, which includes the decryption exponent d. The decryption exponent is the modular multiplicative inverse of e modulo φ(n), where φ(n) is the Euler's totient function of n. Since n is the product of two primes, 43 and 59, φ(n) is (43-1)(59-1) which equals 42 · 58. Now, we need to find d such that it satisfies the congruence ed ≡ 1 (mod φ(n)), which will be d = 13⁻¹ mod 42 · 58. Once d is computed, we can decrypt each part of the message using the formula M = C^d mod n, where M is the original message and C is each part of the encrypted message.
Suppose you pay $1.00 to play the following game. A card is drawn from a standard deck. If it is an ace, you recieve $5.00, if it is a king, queen, or jack, you receive $3.00. Otherwise you recieve no money. Find the expected value of your net winning. Use decimal notation for your answer.
Answer:
0.08
Step-by-step explanation:
A standard deck contains 52 cards. There are 4 aces and 12 kings/queens/jacks. This means that there is a 4/52 (or 1/13) chance of you winning 5$, and a 12/52 (or 3/13) chance of you winning 3$. To find the expected value, we can simply find the average amount of winnings. This can be done by adding the possible winning values for each card.. Since there is a 1/13 chance that you win 5$, we can add 5*1=5 to the sum. For the kings/jacks/queens, we can add 3*3=9 to the sum. Then, since we win nothing for anything else, we can find the expected value to be 14/13 = 1.08 (approximately). Subtracting the 1$ pay, the expected net winning is 0.08, or 8 cents.
3 friends share the cost of a gift. The gift costs $70, but the store manager takes $10 off the market price. What amount should they each pay? What is the answer
Answer:
Amount each friend pays for the gift = $20
Step-by-step explanation:
Market price of a gift = $70
The store manager takes $10 off the market price.
Marked down amount = $10
New cost price = Marked price - Marked down amount [tex]=\$70-\$10=\$60[/tex]
The cost of the gift is divided among three friends.
This means that the cost of gift which is $60 is divided by three to get each one's contribution in the gift.
∴ Amount each friend pays for the gift [tex]=\frac{60}{3}=\$20[/tex]
Express the confidence interval 0.333 less than p less than 0.555 in the form Modifying Above p with caret plus or minus Upper E. Modifying Above p with caret plus or minus Upper E equals nothing plus or minus nothing
Answer: = [tex]0.444\pm 0.111[/tex]
Step-by-step explanation:
The confidence interval for population proportion(p) is given by :-
[tex]\hat{p}-E<p<\hat{p}+E[/tex] (1)
It is also written as : [tex]\hat{p}\pm E[/tex] (*)
The given confidence interval for population proportion :
[tex]0.333<p<0.555[/tex] (2)
Comparing (1) and (2) , we get
Lower limit = [tex]\hat{p}-E=0.333[/tex] (3)
Upper limit = [tex]\hat{p}+E=0.555[/tex] (4)
Adding (3) and (4) , we get
[tex]2\hat{p}=0.888\\\Rightarrow\ \hat{p}=\dfrac{0.888}{2}=0.444[/tex]
Put value of [tex]\hat{p}=0.444[/tex] in (2) , we get
[tex]0.444+E=0.555\\\\\Rightarrow\ E=0.555-0.444=0.111[/tex]
Put values of [tex]\hat{p}=0.444[/tex] and E= 0.111 in (*) , we get
Required form = [tex]0.444\pm 0.111[/tex]
The confidence interval 0.333 to 0.555 can be written in the form 0.444 +/- 0.111 This helps to clearly represent the sample proportion and its margin of error.
The confidence interval 0.333 less than p less than 0.555 can be expressed in the form Modifying Above p with caret plus or minus Upper E. To do this, we need to find the middle point of the interval, which represents the sample proportion and the margin of error (E").
Find the midpoint:The confidence interval can be written as 0.444 plus or minus 0.111.
What are the period and amplitude of the function?
The given graph displays a periodic function with a [tex]5[/tex]-unit period and a [tex]3[/tex]-unit amplitude. Therefore, option C is correct, accurately describing the function's characteristics based on the observed graph.
The given graph indicates a periodic function with repeating patterns. The period is the horizontal distance between two successive peaks or troughs. In this case, the graph repeats every [tex]5[/tex] units horizontally, so the period is indeed [tex]5[/tex]. The amplitude is the vertical distance from the midline to the peak or trough.
Here, the vertical distance is [tex]3[/tex] units, confirming the amplitude as [tex]3[/tex].
Therefore, according to the graph, option C is correct with a period of [tex]5[/tex] and an amplitude of [tex]3[/tex], aligning with the observed characteristics of the function's periodicity and vertical range.
Write a quadratic equation with the given roots. Write the equation in the form ax^2+bx+c=0 , where a, b, and c are integers. –7 and –2
Answer:
x² +9x +14 = 0
Step-by-step explanation:
Since the roots are integers, we can write the equation in the given form using a=1. Then b is the opposite of the sum of the roots:
b = -((-7) +(-2)) = 9
And c is the product of the roots:
c = (-7)(-2) = 14
So, the desired quadratic equation is ...
x² +9x +14 = 0
_____
The attached graph confirms the roots of this equation.
_____
Another way
For root r, a factor of the equation is (x -r). For the given two roots, the factors are ...
(x -(-7))(x -(-2)) = (x +7)(x +2)
When expanded, this expression is ...
x(x +2) +7(x +2) = x² +2x +7x +14
= x² +9x +14
We want the equation where this is set to zero:
x² +9x +14 = 0
___
If a root is a fraction, say p/q, then the factor (x -p/q) can also be written as (qx -p). In this case, expanding the product of binomial factors will result in a value for "a" that is not 1.

Multiplying both sides by 3 we get:
[tex]3x-27-x=69[/tex]
[tex]2x-27=69[/tex]
Adding both sides by 27 and then dividing by 2 we get:
[tex]x=48[/tex]
Therefore, the number of bracelets with she start are 48.

x(x+2)-5(x+2) =0
( x + 2)(x-5) = 0
x = -2 or x = 5
The length of the rectangle cannot be negative so the length is 5 meters
Widith = x+3 = 5-3 = 2 meters
Final answer:
The dimensions of the rectangle are found by solving the quadratic equation derived from the area. The length is 5 meters, and the width is 2 meters, as negative dimensions are not possible.
Explanation:
To find the dimensions of the rectangle with an area of 10 square meters and the sides defined as x and x
- 3, we have derived a quadratic equation x^2 - 3x - 10 = 0 which factors down to (x + 2)(x - 5) = 0. This gives us two possible solutions for x: either x + 2 = 0 or x - 5 = 0. Solving these equations, we find x = -2 or x = 5. Since a rectangle cannot have a negative dimension, we disregard x = -2. Therefore, the length of the rectangle is x = 5 meters and the width is x - 3 = 2 meters.

Matthew picks flowers and sells them to tourists. The function s(t) approximates how many flowers Matthew picks per hour. The function W(h) represents how hours per week Matthew spends picking flowers. What are the units of measurement for the composite function s(W(h))?
a. flowers/hour
b. hours/week
c. flowers/week
d. weeks/flower
Answer:
c Flower/ Week
Step-by-step explanation:
think about it like this
hours (flowers)
____. x. _______
Weeks hours
Both of the hours cancel out similar to unit conversions in chemistry and you are left with flowers per week. since the value of flowers you get per hour you work, and x is dependant on the amount of hours you work in a week. These two functions work in conjuction to give flowers per week picked, this crossing off happens diagonally from left down to the right.
The units of measurement for the composite function s(W(h)) is Option(C) flowers/week.
What is the given unit of the composite function ?Given that the function s(t) approximates how many flowers Matthew picks per hour.
Unit of function s(t) is flowers/hours.
Also given that the function W(h) represents how many hours per week Matthew spends picking flowers.
Unit of W(h) = hours/week .
The composite function s(W(h)) will have unit -
= Flowers/hours * hours/week
= Flowers/week
The units of measurement for the composite function s(W(h)) is Option(C) flowers/week.

One zero of the polynomial function f(x) = x3 − x2 − 20x is x = 0. What are the zeros of the polynomial function?
\Given :
x^{3} +x^{2} -20x
Solution:
x^{3} +x^{2} -20x
taking x common from the given polynomial
⇒x(x^{2} +x-20)=0
⇒x(x(x+5)-4(x+5))=0
⇒x(x+5)(x-4)=0
⇒ x=0 , x+5=0 , x-4=0
⇒x = 0 , x = -5 , x = 4
The zeros of the polynomial function f(x) = x³ - x² - 20x are x = 0, x = 5, and x = -4.
To find the remaining zeros, we can use polynomial division or factoring techniques. Since the given polynomial is already in its factored form, we can use the zero-product property to find the other zeros.
The given polynomial f(x) = x³ - x² - 20x can be factored as
f(x) = x(x² - x - 20).
Now, we have two factors: x and (x² - x - 20).
To find the zeros of the second factor, we can set it equal to zero and solve for x. So, we have
x² - x - 20 = 0.
We can factor this quadratic equation by splitting the middle term:
x² - x - 20 = (x - 5)(x + 4).
Now, we have three factors: x, (x - 5), and (x + 4). To find the zeros, we set each factor equal to zero and solve for x:
x = 0 (given) x - 5 = 0 => x = 5 x + 4 = 0 => x = -4
Therefore, the zeros of the polynomial function
f(x) = x³ - x² - 20x are x = 0, x = 5, and x = -4.

The function f(x)=ln(9.2x) is a horizontal compression of the parent function by a factor of 1/9.2
Step-by-step explanation:
The multiplication of a function by a number compresses or stretches the function vertically while to compress or stretch the function horizontally, the input variable is multiplied with a number.
i.e.
[tex]For\ f(x) => g = f(bx)[/tex]
where b is a constant.
Now
If b>0 then the function is compressed horizontally
The given function is:
[tex]f(x) = ln\ x\\Transformed\ to\\f(x) = ln\ (9.2x)[/tex]
As the variable in function is multiplied with a number greater than zero, the function will stretch horizontally.

Miguel earns 2,456.75 every month he also earns an extra 4.75 every time he sells a new gym membership last month Miguel sold 32 new gym membership how much money did Miguel earn last month
Answer: Total amount of money earned last month = $2608.75
Step-by-step explanation:
Miguel earns 2,456.75 every month. This is his constant pay for the month. He also earns an extra 4.75 every time he sells a new gym membership.
Last month, Miguel sold 32 new gym membership. This means that the extra money that he earned for last month will be the number of new gym membership sold times the amount her earns per new gym membership sold. It becomes
32 × 4.75 = 152
Total amount of money earned last month will be sum of his monthly salary + the extra earned. It becomes
2456.75 + 152 = $2608.75
