robert leaves his home to go to his office . he drives 6km due north and then 4 km due east. approximatel what is the shortest distance from roberts home to his office , in kms?

Answers

The shortest distance from Roberts home to his office can be found by using the Pythagorean theorem. The triangle that is created is a right triangle. We need to solve for the hypotenuse, the side directly across from the right angle created from this scenario. This Theorem says a^2+b^2=c^2, so 4x4+6x6=c^2. 52=c^2. The square root of 52 is approximately 7.2 km.

To find the shortest distance from Robert's home to his office, we use the Pythagorean theorem with the distances traveled north and east to calculate the length of the hypotenuse, which is approximately 7.2 kilometers.

Robert leaves his home and drives 6 km due north and then 4 km due east. To determine the shortest distance from Robert's home to his office, we can use the Pythagorean theorem. This scenario forms a right-angled triangle where the two sides are the north-bound and east-bound legs of his journey, and the hypotenuse is the shortest distance.

Step 1: Label the lengths of the two sides adjacent to the right angle as 'a' and 'b', where 'a' is the 6 km north-bound leg and 'b' is the 4 km east-bound leg.

Step 2: Apply the Pythagorean theorem, which states that the square of the hypotenuse (c) is equal to the sum of the squares of the other two sides:

c² = a² + b²

Step 3: Substitute the known values into the theorem:

c² = 6² + 4²

Step 4: Calculate the squares of the sides and sum them:

c² = 36 + 16

Step 5: Sum the squares gives us:

c² = 52

Step 6: Take the square root of both sides to find 'c':

c = √52

Step 7: Calculate the square root which approximately equals:

c = 7.2 km

Therefore, the shortest distance from Robert's home to his office is approximately 7.2 kilometers.

Answers

The answer is 32.45 because 18^2+27^2=x^2

Answer:

the length of the hypotenuse = 32.45 centimeters

Step-by-step explanation:

A right triangle has legs that are 18 centimeters and 27 centimeters long

In a right angle triangle , to find hypotenuse we use Pythagorean theorem

[tex]c^2= a^2+b^2[/tex]

where a  and b are the length of two legs

Given a= 18  and b = 27

Lets find out C , plug in all the value in the formula

[tex]c^2= 18^2+27^2[/tex]

[tex]c^2=324 +729= 1053[/tex]

c^2 = 1053

now take square root on both sides

c= 32.45

So the length of the hypotenuse = 32.45 centimeters

Length of a rectangle is 4 inches less than twice it’s width of the perimeter is 70 inches what’s the dimensions?

Answers

W= width

Find the exact values of the remaining trigonometric functions of θ satisfying the given conditions. (if an answer is undefined, enter undefined.) csc θ = 14, cot θ < 0

Answers

The answer is undefined.
Final answer:

Given that csc θ = 14 and cot θ < 0, we find that sin θ = 1/14 and cos θ must be negative. We use the identity sin² θ + cos² θ = 1 to solve for the exact value of cos θ, selecting the negative solution. The remaining trigonometric functions are then found using these values.

Explanation:

Given that the cosecant of theta (csc θ) is 14 and cotangent of theta (cot θ) is less than zero, we can find the other trigonometric values. We begin by recalling that cosecant is the reciprocal of the sine function, so sin θ = 1/14. Subsequently, we are told cot θ < 0, which means either the cosine or the sine (or both) must be negative.

Since cot θ is negative and we know sin θ is positive (since csc θ is positive), then we can conclude that cos θ must be negative. However, the exact value of cos θ is not readily identifiable from these properties alone.

To find the trigonometric value of cos θ, we can utilize the identity sin² θ + cos² θ = 1. Substituting our known sin θ value, we solve for cos θ. This gives us two possible solutions for cos θ, either positive or negative. As previously deduced, we select the negative solution for cos θ. The remaining trigonometric functions can then be found given these values:

tan θ = sin θ / cos θ,sec θ = 1 / cos θ, andcot θ = 1 / tan θ, or alternatively, cos θ / sin θ.

Given that f(x) = 5x2 − 100, find x.

Answers

Final answer:

To find x, we need to solve the quadratic equation 5x^2 - 100 = 0 using the quadratic formula.

Explanation:

To find x, we need to solve the quadratic equation 5x^2 - 100 = 0 using the quadratic formula. The formula is x = (-b ± √(b^2 - 4ac)) / (2a), where a, b, and c are the coefficients of the quadratic equation.

In this case, a = 5, b = 0, and c = -100. Plugging these values into the quadratic formula, we get:

x = (-0 ± √(0^2 - 4 * 5 * -100)) / (2 * 5)

Simplifying further, we have:

x = (√2000) / 10

Therefore, x equals approximately ±14.14.

If a 6-sided die is rolled 5 times and rolling a 2 is considered to be a success, what are the chances of rolling exactly three successes?

show work

A.) 0.32% B.) 16.67% C.) 32.15% D.) 33.33% E) none of these

Answers

Final answer:

The probability of rolling exactly three 2s in five rolls of a six-sided die is 32.15%, calculated using the binomial probability formula. The correct answer from the provided options is C) 32.15%.

Explanation:

The student is asking about the probability of achieving a specific number of successes in a series of independent events, which is a problem that can be solved using the binomial probability formula. In this case, a success is defined as rolling a 2 on a six-sided die. The probability of rolling a 2 (success) on a single roll is \(\frac{1}{6}\), and the probability of not rolling a 2 (failure) is \(\frac{5}{6}\).

Therefore, the probability of rolling exactly three 2s in five rolls can be calculated by the formula:

\(P(X=k) = \binom{n}{k} \cdot p^k \cdot (1-p)^{n-k}\)

where \(n\) is the number of trials, \(k\) is the number of desired successes, and \(p\) is the probability of a single success.

Substituting the values:

\(P(X=3) = \binom{5}{3} \cdot \left(\frac{1}{6}\right)^3 \cdot \left(\frac{5}{6}\right)^{5-3}\)

\(P(X=3) = 10 \cdot \left(\frac{1}{6}\right)^3 \cdot \left(\frac{5}{6}\right)^2\)

\(P(X=3) = 10 \cdot \frac{1}{216} \cdot \frac{25}{36}\)

\(P(X=3) = \frac{250}{7776}\)

\(P(X=3) \approx 0.03215 \text{ or } 3.215\%\)

So the correct answer from the provided options is C) 32.15%.

Final answer:

The chances of rolling exactly three successes when rolling a 6-sided die 5 times, where rolling a 2 is considered a success, is approximately 2.143%.

Explanation:

To find the chances of rolling exactly three successes, we need to use the concept of binomial probability. In this case, the probability of rolling a 2 (success) is 1/6, and the probability of not rolling a 2 (failure) is 5/6. We can use the formula for binomial probability: P(X=k) = (n choose k) * p^k * (1-p)^(n-k), where n is the number of trials, k is the number of successes, and p is the probability of success in one trial.

For this problem, n=5 (since the die is rolled 5 times), k=3 (we want exactly three successes), and p=1/6 (probability of rolling a 2). Plugging these values into the formula:

P(X=3) = (5 choose 3) * (1/6)^3 * (5/6)^(5-3)

Simplifying, we get:

P(X=3) = 10 * (1/6)^3 * (5/6)^2 = 10 * (1/216) * (25/36) = 250/11664 ≈ 0.02143 ≈ 2.143%

Naoya read a book cover to cover in a single session, at a rate of 555555 pages per hour. After 444 hours, he had 350350350 pages left to read.

Answers

There's no question in this statement.

The question involves a mathematical reading rate scenario where Naoya calculates how much of a book he has left to read. Since the numbers provided are unrealistic, an example with plausible figures is used to illustrate the process of determining total reading time and daily reading goals.

The question deals with a reading rate calculation problem involving Naoya, who has read part of a book and wants to figure out how much more he needs to read. We can figure out the total number of pages in the book by considering the pages he has read at the rate of 555,555 pages per hour over 444 hours, and adding the remaining 350,350,350 pages he has left to read. However, it appears there are typographical errors in the question with the repetition of numbers, which should likely be simplified to realistic figures before we can calculate the total number of pages in the book.To apply the concept efficiently, let's take an example with realistic numbers similar to the approach mentioned for Marta. Suppose Marta reads at a rate of 48 pages per hour and she needs to finish a 497-page novel. We divide the total page count (497) by her hourly rate (48 pages/hour) to find the total hours needed, which is approximately 10.35 hours or roughly 10 to 11 hours.

If Marta wishes to finish the novel over two weeks, she would divide her total reading time by the number of days she plans to read, ensuring she allocates enough time each day to reach her goal. Similar reading strategies can be applied whether balancing act, early bird, or taking the approach of reading a certain number of pages each day to make a larger task more doable.

We have a coordinate plane that is placed over an empty lot. So you and your friend are set at that coordinate system, so I'll give you the representation of each statement and the distance that the snowball travels from your friend's hand to you.

1. You face the positive y-axis and your friend faces the negative y-axis. 

This statement is represented in Figure 1. So you are the Red square and your friend is the Blue one. The arrows upon the squares mean that you are facing the positive y-axis and your friend the negative one. 

2. You run 20 feet forward, then 15 feet to your right. At the same time, your friend runs 16 feet forward,  then 12 feet to her right.

This is shown in Figure 2. So, at the coordinate system, you move 20 feet upward and 15 feet to your right, that is, you walk from the origin to the point [tex]P_{1}(15,20)[/tex] first moving through the positive y-axis and next through the positive x-axis. On the other hand, your friend moves 16 feet downward and 12 feet to her right, that is, she walks from the origin to the point [tex]P_{2}(-12,-16)[/tex] first moving through the negative y-axis and next through the negative x-axis. 

3. She stops and hits you with a snowball.

This statement is represented in Figure 3. So the snowball has been drawn in gray. The line from your friend to you is the distance the snowball runs.

4. Distance the ball runs.

We can get this answer by using the Distance Formula, that is:

[tex]d=\sqrt{(x_{1}-x_{2})^{2}+(y_{1}-y_{2})^2} \\ d=\sqrt{[15-(-12)]^{2}+[20-(-16)]^2} \\ \boxed{d=45ft}[/tex]

[tex]3 x^{3}y+15xy-9 x^{2} y-45y [/tex]

When you use a keyboard it is customary to use "^" to denote an exponent is coming so you could have written: 3x^3y+15xy-9x^2y-45y just to be clear.

PART A
To factor out the GCF we are looking for the greatest factor among the terms. Looking at the coefficients (the numbers) the largest number they can all be divided by is 3 so we will pull out a 3. Notice also that each term has a y in it so we can pull out that.

This gives us: [tex] 3 x^{3}y+15xy-9 x^{2} y-45y=3y( x^{3}+5x-3 x^{2} -15)[/tex]

To factor is to write as a product (something times something else). It undoes multiplication so in this case if you take what we got and multiplied it back you should get the expression we started with.

PART B
Start with the answer in part A. Namely, [tex]3y( x^{3}+5x-3 x^{2} -15)[/tex]. For now let's focus only on what is in the parenthesis. We have four terms so let's take them two at a time. I am separating the expression in two using square brackets. [tex][( x^{3}+5x)]-[3 x^{2} -15][/tex]

Let's next factor what is in each bracket:
[tex][( x^{3}+5x)]-[3 x^{2} -15] = [x( x^{2} +5)]-[3( x^{2} +5)][/tex]

Notice that both brackets have the same expression in them so now we factor that out: [tex] [x( x^{2} +5)]-[3( x^{2} +5)] = (x-3)( x^{2} +5)[/tex]

Our original expression (the one we started the problem with) had a 3y we already pulled out. We need to include that in the completely factored expression. Doing so we get: [tex]3 x^{3}y+15xy-9 x^{2} y-45y =(3y) (x-3)( x^{2} +5)[/tex]

You must use the substitution method. 3x+2y=11
y=5x-1

Answers

plug in y=5x-1 for y in 3x+2y=11

3x+2(5x-1)=11
3x+10x-2=11
13x=13
x=1

plug x=1 to y=5x-1 to find y

y=5(1)-1
y=5-1
y=4

Step-by-step explanation:

What is the simplified form of i13?

A. -i
B. 1
C. -1
D. i

Answers

First what you should know is that:
 i = root (-1)
 We note that in this case the exponent is odd.
 So we can rewrite the expression as:
 i ^ 13 = (i ^ 2) * (i ^ 2) * (i ^ 2) * (i ^ 2) * (i ^ 2) * (i ^ 2) * i
 i ^ 13 = (- 1) * (- 1) * (- 1) * (- 1) * (- 1) * (- 1) * i
 i ^ 13 = (1) * i
 i ^ 13 = i
 Answer: 
 the simplified form of i ^ 13 is: 
 D. i

The simplified form of i^13 is -i.

The simplified form of i^13 is -i.

To find the simplified form, remember that i^4 = 1, so i^13 = i^(4*3+1) = i^(4*3) * i = (i^4)^3 * i = 1^3 * i = i.

Therefore, the simplified form of i^13 is -i.

Trevor is analyzing a circle, y2 + x2 = 49, and a linear function g(x). Will they intersect?

Answers

We have a circumference that is given by the following equation:

[tex]x^{2}+y^{2}=49[/tex]

We can write this equation in its standard form as follows:

 [tex]x^{2}+y^{2}=7^{2} \\ where \ the \ radius \ r=7[/tex]

On the other hand, the linear function is given as the following table:

[tex]x \ \ \ \ \ \ \ \ g(x) \\ -1 \ \ -9.2 \\ 0 \ \ \ \ \ -9 \\ 1 \ \ \ \ \ -8.8[/tex]

To check if the circle and the line intersects, let's substitute the equation of the line into the equation of the circle to see if there is a real solution, so:

[tex]x^{2}+(0.2x-9)^{2}=49 \\ \\ \therefore x^{2}+0.04x^{2}-3.6x+81=49 \\ \\ \therefore 1.04x^{2}-36x+32=0 \\ \\ Solving \ for \ x: \\ x_{1}=33.70 \\ x_{2}=0.91 \\ \\ Solving \ for \ y: \\ y_{1}=0.2(33.70)-9=-2.26 \\ y_{2}=0.2(0.91)-9=-8.18[/tex]

 Finally the intersects are:

 [tex]P_{1}(33.70, -2.26) \ and \ P_{2}(0.91, -8.18)[/tex]

The ratio of two sides of a parallelogram is 3:4 and the perimeter is 28 in. Find the lengths of the sides of the parallelogram.

Answers

We have w/h = 3/4 and 2w + 2h = 28 in;
Then, w = 3h/4;
2x(3h/4) + 2h = 28;
3h/2 + 2h = 28;
3h + 4h = 56;
7h = 56;
h = 8 in;
w = 24/4;
w = 6 in.

Sides of a parallelogram are equal to [tex]\boldsymbol{6}[/tex] inches and [tex]\boldsymbol{8}[/tex] inches if ratio of sides is [tex]3:4[/tex] and perimeter is equal to [tex]28[/tex] inches.

Parallelogram

A basic quadrilateral with two pairs of parallel sides is known as a parallelogram.

Ratio of two sides of a parallelogram [tex]=\boldsymbol{3:4}[/tex]

Let the sides be [tex]3x,4x[/tex].

Perimeter of a parallelogram [tex]=\boldsymbol{28}[/tex] in.

Perimeter of a parallelogram is equal to sum of all the sides.

[tex]3x+4x+3x+4x=28[/tex] in.

                       [tex]14x=28[/tex] in.

                           [tex]x=2[/tex] in.

So, sides are equal to [tex]3(2),4(2)[/tex] that is sides are equal to [tex]\boldsymbol{6}[/tex] inches and [tex]\boldsymbol{8}[/tex] inches.
