What is the area of the shaded region?
Round your final answer to the nearest hundredth.
The larger circle is shaded.
Answer:
Circular shapes - They are those planner shapes that represent the locus of all the points that has a constant distance from a fixed point on the plane. This constant distance is termed as the radius of the circle and the fixed point is known as the center of the circle.
The center of the circle is enclosed by all the points on its periphery.
The circumference of the circle is the total length of its periphery around the center.
Concentric circles are two circles that have the same center
Step-by-step explanation:
Which of these equations correctly represents the following scenario: In her prime, 40 million people knew who Britney Spears was, but that number has been decreasing by 10% each year. So, since 90% of people still recognize her each year, how many people still know who Britney is each year?
y = 40,000,000(0.9)x
y = 0.9(40,000,000)x
y = 40,000,000(0.01)x
y = 0.1x + 40,000,000
y = 0.01(40,000,000)x
Answer:
Its the first option
40,000,000(0.9)x.
Step-by-step explanation:
90% recognise her each year so after 1 year so the number (N) is:
N = 40,000,000(0.90)^1 = 36,000,000 recognise her after 1 year.
N = 40,000,000(0.90)^2 = 32,400,000 recognise her after 2 yeas
- and so on.
After x years:
N = 40,000,000(0.90)^x.
Note the x is a power and is best written as ^x.
The correct equation to represent the given scenario is [tex]y = 40,000,000(0.9)^x[/tex]. This equation represents a geometric sequence, with the initial quantity being 40,000,000 and decreasing by 10% each year.
Explanation:The scenario is a geometric sequence, where the number of people who still recognize Britney Spears each year is decreasing by 10%. To represent this situation mathematically, we can use a geometric equation: [tex]y = a \cdot r^x[/tex]where 'a' is the initial quantity, 'r' is the ratio of decrease or increase, and 'x' is the number of time periods.
In this case, 'a' is 40,000,000 (the initial amount of people), 'r' is 0.9 (representing a 10% decrease each year), and 'x' will represent the number of years since her prime. Thus, the correct equation out of the options to represent the scenario is [tex]y = 40,000,000(0.9)^x.[/tex]

"Benny decided to look at the price of new and used vans. Benny found a used van for $3000. Benny found that he paid 20% of the price of a new van. How much would a new van cost?"
Answer:
$15000
Step-by-step explanation:
We have that the value of the truck is $ 3000 and that this payment is equivalent to 20% of the value of a new truck, therefore the value of the new truck would be:
% of value value

make as the brainliest
Final answer:
The volume of a cube with an edge length of 14m is 2,744 cubic meters (m³), calculated using the formula V = a³, where a is the edge length.
Explanation:
To find the volume of a cube with an edge length of 14m, we use the formula for the volume of a cube, which is V = a³, where a is the length of an edge of the cube. In this case, each edge is 14 meters long. Therefore, the volume of the cube is calculated as follows:
V = 14m × 14m × 14m = 2,744 m³
This means the volume of the cube is 2,744 cubic meters (m³). It's important to remember that the volume measures the amount of space within the cube, and the unit of measure for volume in the International System of Units (SI) is cubic meters (m³).
A tower is 1964 feet tall. The angle of elevation from the base of an office building to the top of the tower is 37degrees. The angle of elevation from the roof of the office building to the top of the tower is 19degrees.
To find the height of the office building and the angle of elevation to the top of the tower, we can use the tangent function and solve two equations simultaneously.
To find the height of the office building and the angle of elevation from the base to the top of the tower, we can use the Tangent function.
Tan(angle) = Opposite/Adjacent
For the first angle (37 degrees), the opposite side is the height of the tower (1964 feet) and the adjacent side is the height of the office building.
So, tan(37) = 1964/Adjacent.
For the second angle (19 degrees), the opposite side is again the height of the tower (1964 feet) and the adjacent side is the height of the office building + the height from the roof to the top of the tower.
So, tan(19) = 1964/(Adjacent + Roof Height).
We can solve these two equations simultaneously to find the height of the office building and the height from the roof to the top of the tower.

Arie has $46 in his account and is saving $8.50 each week. Olga has $14 in her savings account and is saving $12.50 each week. After how many weeks will Arie and Olga have the same in their accounts?
Answer:
5 weeks until they have the same
Arie and Olga have the same amount in their accounts in 8 weeks.
What is an expression?An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.
Now it is given that,
Amount in Arie's account = $46
Arie's each week savings = $8.50
Amount in Olga 's account = $14
Olga 's each week savings = $12.50
Let x be the number of weeks when Arie and Olga will have the same amount in their accounts
Total savings of Arie = 8.5x
Total savings of Olga = 12.5x
Amount in Arie's account = 8.5x + 46
Amount in Olga's account = 12.5x + 14
For, Arie and Olga have the same amount in their accounts
8.5x + 46 = 12.5x + 14
Taking alike terms together,
12.5x - 8.5x = 46 - 14
⇒ 4x = 32
Dividing both side by 4 we get,
x =8 weeks
which is the required number of weeks.
Thus, Arie and Olga will have the same amount in their accounts in 8 weeks.

Historically, the mean yield of corn in the United States has been 120 bushels per acre with a standard deviation of 12. A survey of 40 farmers this year gives a sample mean yield of 125 bushels per acre . Let p be the mean yield of corn nationally for this year. Supposing that the past standard deviation is still correct, what is the p-value for testing a null hypothesis of mu=120 against an alternative of mu not equal to 20 ? A 0.0041 B 0.0082 C 2.64 D 125
Answer:
[tex]z=\frac{125-120}{\frac{12}{\sqrt{40}}}=2.64[/tex]
P-value
Since is a two sided test the p value would be:
[tex]p_v =2*P(z>2.64)=0.0082[/tex]
And the best answer would be
B 0.0082
Step-by-step explanation:
Data given and notation
[tex]\bar X=125[/tex] represent the mean height for the sample
[tex]\sigma=12[/tex] represent the population standard deviation
[tex]n=40[/tex] sample size
[tex]\mu_o =120[/tex] represent the value that we want to test
[tex]\alpha[/tex] represent the significance level for the hypothesis test.
t would represent the statistic (variable of interest)
[tex]p_v[/tex] represent the p value for the test (variable of interest)
State the null and alternative hypotheses.
We need to conduct a hypothesis in order to check if the true mean is 120 or not, the system of hypothesis would be:
Null hypothesis:[tex]\mu = 120[/tex]
Alternative hypothesis:[tex]\mu \neq 120[/tex]
If we analyze the size for the sample is > 30 and we know the population deviation so is better apply a z test to compare the actual mean to the reference value, and the statistic is given by:
[tex]z=\frac{\bar X-\mu_o}{\frac{\sigma}{\sqrt{n}}}[/tex] (1)
z-test: "Is used to compare group means. Is one of the most common tests and is used to determine if the mean is (higher, less or not equal) to an specified value".
Calculate the statistic
We can replace in formula (1) the info given like this:
[tex]z=\frac{125-120}{\frac{12}{\sqrt{40}}}=2.64[/tex]

Suppose your new business made a profit during the first year of $3000. If the profit increased 12% per year, find the total of all profit earned by the end of the first 5 years.
Answer:
Therefore the total of all profit earned by the end of of the the first 5 years is $19,058.542.
Step-by-step explanation:
To find total profit earned per year, we need to use the compound growth formula.
The compound growth formula:
[tex]A= P(1+r)^t[/tex]
A= Amount after t years
P= initial amount
r= rate of growth
t= time in year.
Given that,
New business made a profit during the first year of $3000.
If the profit increased 12% per year.
Here P= $3,000 and r =12%=0.12 , t=1 years
Plugging all value in the above formula:
[tex]A=3000(1+0.12)^1[/tex]
=3000(1.12)
=$3360
Profit after 2 year is $3,360.
Now, P= $3,000 and r =12%=0.12 , t=3 years
[tex]A=3000(1+0.12)^2[/tex]
=3000(1.12)²
=$3763.2
Similar the profit at 4 year is
[tex]A=3000(1+0.12)^3[/tex]
=3000(1.12)³
=$4214.784
The profit at 5th year is
[tex]A=3000(1+0.12)^4[/tex]
=3000(1.12)⁴
=$4720.558
Therefore the total of all profit earned by the end of of the the first 5 years is=$(3,000+3360+3763.2+4214.784+4720.558)
=$19,058.542

f(x) = x4 + x3 + 2x2 + ax + b,
where a and b are constants.
When f(x) is divided by (x - 1), the remainder is 7
(a) Show that a + b = 3
When f(x) is divided by (x + 2), the remainder is -8
(b) Find the value of a and the value of b
Answer:
see explanation
Step-by-step explanation:
The remainder theorem states that if f(x) is divided by (x - h)
The the remainder is f(h)
(a)
Given f(x) is divided by (x - 1) then remainder is f(1), thus
f(1) = [tex]1^{4}[/tex] + 1³ + 2(1)² + a + b = 7, that is
1 + 1 + 2 + a + b = 7
4 + a + b = 7 ( subtract 4 from both sides )
a + b = 3 ← as required → (1)
(b
Given f(x) is divided by (x + 2) then the remainder is f(- 2), thus
f(- 2) = [tex](-2)^{4}[/tex] + (- 2)³ + 2(- 2)² + 2a + b = - 8, that is
16 - 8 + 8 + 2a + b = - 8
16 + 2a + b = - 8 ( subtract 16 from both sides )
2a + b = - 24 → (2)
Multiply (1) by 2
2a + 2b = 6 → (3)
Add (2) and (3) term by term to eliminate the term in a
3b = - 18 ( divide both sides by 3 )
b = - 6
Substitute b = - 6 into (1)
a - 6 = 3 ( add 6 to both sides )
a = 9
Thus a = 9 and b = - 6
Final answer:
To solve for the constants a and b in the polynomial function f(x), we apply the remainder theorem to the given division scenarios. Setting up and solving a system of linear equations using the remainders allows us to find that a is 9 and b is -6.
Explanation:
The given function is f(x) = x^4 + x^3 + 2x^2 + ax + b, and we need to find the constants a and b given that when f(x) is divided by (x - 1), the remainder is 7, and when divided by (x + 2), the remainder is -8.
To find a + b, we apply the remainder theorem. When a polynomial f(x) is divided by (x - p), the remainder is f(p). Therefore, for (x - 1):
f(1) = 1 + 1 + 2 + a + b = 7
4 + a + b = 7
a + b = 3
Similarly, for (x + 2):
f(-2) = (-2)^4 + (-2)^3 + 2(-2)^2 + a(-2) + b = -8
16 - 8 + 8 - 2a + b = -8
16 - 2a + b = -8
We already know that a + b = 3, so we can set up a system of equations:
a + b = 3
-2a + b = -24
Solving for a and b:
Subtracting the first equation from the second: -3a = -27
Divide by -3: a = 9
Substitute a into the first equation: 9 + b = 3
Solve for b: b = -6

Explain How to find the volume of a cube whose edge length is 1/4 yd. Then find the volume of such a cube
Answer:
[tex]Volume=0.015625\ yd^3[/tex]
Step-by-step explanation:
-A cube is a 3-D object whose height=length=width.
-To find its volume, we multiply its length by width by height dimensions.
#We can calculate the volume of a cube using the formula:
[tex]V=length\times width\times height\\\\=0.25 \ yd\times 0.25\ yd \times 0.25\ yd\\\\=(0.25\ yd)^3\\\\=0.015625\ yd^3[/tex]
Hence, the volume of the cube is [tex]0.015625\ yd^3[/tex]
To find the volume of a cube with an edge length of 1/4 yard, cube the length of the edge. The volume of the cube is 1/64 cubic yards.
Explanation:To find the volume of a cube, you need to cube the length of its edge. In this case, the edge length is 1/4 yard. So, the volume formula becomes (1/4)^3 = 1/4 × 1/4 × 1/4 cubic yards. Simplifying further, we have 1/64 cubic yards as the volume of the cube.

Mrs. Garcia has two kinds of flowers in her garden. The ratio of lilies to daisies in the garden 3:2 if there are 15 lilies, what is the total number of flowers in her garden?
Answer:
The total number of flowers in Mrs. Garcia's garden is 25.
Step-by-step explanation:
The ratio of lilies to daisies is 3:2 and there are 15 lilies. We need to compute the number of daisies first and then add both the number of daisies and lilies to compute the total number of flowers. Using the ratio method:
Lilies : Daisies
3 : 2
15 : x
By cross multiplying we get:
3x = 15*2
3x = 30
x = 10
Hence, the total number of flowers in the garden are:
10 + 15 = 25
The total number of flowers in Mrs. Garcia's garden is 25.
Answer:
25
Step-by-step explanation:
Given that the number of lilies = 15
Given ratio = 3:2
Let the total number of flowers be X
Let the number of daisies be 'a'
3/2 = 15/a
3×a = 2×15
3a = 30
a = 30/3
a = 10
X = number of lilies + number of daisies
X = 15 + 10
X = 25

Since there is a negative inside the radical, we need to have an imaginary number: [tex]i=\sqrt{-1}[/tex] . So, [tex]\sqrt{-12} =i\sqrt{12} =2i\sqrt{3}[/tex]
Add 3 to both sides: x = [tex]3[/tex] +/- [tex]2i\sqrt{3}[/tex]
3. Divide by -5 from both sides: (n - 2)^2 = -2
Square root both sides: n - 2 = [tex]\sqrt{-2}[/tex]
Again, we have to use i: [tex]n-2=\sqrt{-2} =i\sqrt{2}[/tex]
Add 2 to both sides: n = [tex]2[/tex] +/- [tex]i\sqrt{2}[/tex]
Hope this helps!
Answer:
1. x = 2sqrt(2) - 7, -2sqrt(2) - 7
2. No real solutions
x = 3 + 2sqrt(3) i, 3 - 2sqrt(3) i
3. No real solutions
n = 3 + sqrt(2) i, 3 - sqrt(2) i
Step-by-step explanation:
1. 2(x + 7)² = 16
(x + 7)² = 8
x + 7 = +/- sqrt(8) = +/- 2sqrt(2(
x = 2sqrt(2) - 7, -2sqrt(2) - 7
2. (x - 3)² = -12
A perfect square can never be negative for real values of x
(x - 3) = +/- i × sqrt(12)
x - 3 = +/- i × 2sqrt(3)
x = 3 +/- i × 2sqrt(3)
3. -5(n - 3)² = 10
(n - 3)² = -2
A perfect square can never be negative for real values of x
n - 3 = +/- i × sqrt(2)
n = 3 +/- i × sqrt(2)
Dennis has three identical cylinders filled with water. How many cones should he be able to fill with the water if the cones have the same radius and the same height as the cylinders?
Answer:
3 cylinder will fill 9 cones with water
Step-by-step explanation:
This problem bothers on mensuration of slides, cone and cylinder
We know that the
Volume of a cylinder = πr²h
Volume of a cone = 1/3(πr²h)
Given that both cylinder and cone has same height and radius
From the given expression we can deduce that the cone is 3 times smaller than the cylinder in volume
So if 1 cylinder will fill 3 cones
Then 3 cylinders will fill x cones
By cross multiplication we have
x= 3*3cones
x= 9 cones
Hence 3 cylinder will fill 9 cones with water
Answer:
9 cones
Step-by-step explanation:
The formula to find a volume of a cylinder is:
V1 = pi*r^2*h
Where r is the base radius and h is the height
The formula to find a volume of a cone is:
V2 = (1/3)*pi*r^2*h
So, if they have the same base radius and same height, we have that:
V1/V2 = 1/(1/3) = 3
The volume of the cylinder is 3 times bigger than the volume of the cone, so each cylinder of water can fill 3 cones.
Is Dennis has 3 cylinders, he is able to fill 3*3 = 9 cones with water.

The regular price of a computer is $1200 and the regular price of a printer is $300. The regular price of a computer is 1200 dollars and the regular price of a printer is 300 dollas. An electronics store has a promotion that offers a 40% 40 percent discount on the printer when the computer is purchased at the regular price. What is the total cost of the computer and the printer at the promotional price?
Answer:
$1380
Step-by-step explanation:
The regular price of a computer is $1200The regular price of a printer is $300.The electronics store offers a 40% discount on the printer only when the computer is purchased at the regular price.
Discount on the Printer = 40% of $300 =0.4 X 300 =120
Promotional Price of the Printer = $300-120 =$180
Therefore, the total cost of the computer and the printer at the promotional price
=Regular price of a computer + Promotional Price of the Printer
=1200+180
=$1380
