Answer:
A = 25π square feet
Step-by-step explanation:
C = 2πr
10π = 2πr
10π = 2πx
10π / 2π = 2πx / 2π
5 = x
This means 5 is the radius of the circle. We now need to find the area:
A = πr[tex]r^{2}[/tex]
A = π(5)²
A = π(25)
A = 25π

What amount of money must you invest at 6.8% compounded monthly, in order to have $10,000 after 10 years? Round your answer to the nearest dollar.
The amount of money which is invested at 6.8% compounded monthly, in order to have $10,000 after 10 year is $5076.
What is compound interest?
Compound interest is the amount charged on the principal amount and the accumulated interest with a fixed rate of interest for a time period.
The formula for the final amount with the compound interest formula can be given as,
[tex]A=P\times\left(1+\dfrac{r}{n\times100}\right)^{nt}\\[/tex]
Here, A is the final amount (principal plus interest amount) on the principal amount P of with the rate r of in the time period of t.
The rate of interest is 6.8% on the amount which is compounded monthly
The value of final amount is $10,000 after the time period of 10 years. There are total 12 months a year. Thus, the value of principal amount using the above formula is,
[tex]10000=P\times\left(1+\dfrac{6.8}{12\times100}\right)^{12\times10}\\10000=P\times1.97\\P=\dfrac{10000}{1.97}\\P=5076.14\\P\approx5076[/tex]
Thus, the amount of money which is invested at 6.8% compounded monthly, in order to have $10,000 after 10 year is $5076.

the length of the side sqaure A is 50% OF THE LENGTH OF THE SIDE SQUARE b
Let's say the side length of square A is x, which means the side length of square B is 2x.
Then, the area of square A can be written as , and the area of square B can be written as .
There's no diagram here with shaded region, so I'll just find the area of square A as a percentage of the area of square B:

I think its 71, but I am not 100% sure. Take this as a secondary answer.
Answer:
C. 71°
Step-by-step explanation:
If angles 4 and 12 are equal and complementary, then they measure 45°
There is a triangle formed by angles 3, 11 and 12
the angle 3 = 64°, angle 12 = 45°
Then by the property of triangles:
angle 11 = (180 - 64 - 45)° = 71°

If tan x = 1/2 , find sin x
The values of x are in between 0 and 2π
The equation tan(x) = 1/2 is an illustration of a trigonometry ratio
The value of sin(x) is sin(x) = ±1/√5
How to determine sin (x)?The tangent ratio is given as:
tan(x) = 1/2
The tangent ratio is calculated using:
tan(x) = opposite/adjacent
So, we have:
Opposite = 1 and adjacent = 2
Calculate the hypotenuse using:
Hypotenuse² = Opposite² + adjacent²
The equation becomes
Hypotenuse² = 1² + 2²
Hypotenuse² = 5
Take the square root of both sides
Hypotenuse = ±√5
The sine ratio is:
sin(x) = Opposite/Hypotenuse
So, we have:
sin(x) = ±1/√5

In a city, 45% of the bus riders with a monthly pass are students. In a random sample of 50 bus riders with monthly passes, 18 are students.
What is ρ and ρˆ ?
ρ=0.45, ρˆ=0.18
ρ=0.45, ρˆ=0.36
ρ=0.18, ρˆ=0.45
ρ=0.36, ρˆ=0.45
Answer:
ρ =45% or 0.45
ρ with ^ = [tex]\frac{18}{50} =0.36[/tex] or equivalently 36%
Step-by-step explanation:
ρ represents the population proportion of the bus riders, with a monthly pass, who are students.
The population proportion is simply the percentage of the entire population with a particular characteristic. We have been informed that in a city, 45% of the bus riders with a monthly pass are students. This means that 45% of the whole population of bus riders with a monthly pass are students. Therefore, our ρ is simply 45% or 0.45.
ρ with ^ represents the sample proportion of the bus riders, with a monthly pass, who are students. This is a statistic or an estimator as it is normally used to estimate the value of ρ, the population proportion. It is calculated using the formula;
ρ with ^ = [tex]\frac{x}{n}[/tex]
where n represents the size of the sample and x the number of individuals in the sample with a certain desired characteristic. We have been informed that;
in a random sample of 50 bus riders with monthly passes, 18 are students.
Using the above formula and the values given we have;
ρ with ^ = [tex]\frac{18}{50} =0.36[/tex] or equivalently 36%

Write the equation for function g(x)
Answer:
g(x) = (x + 2)^2 + 1
Step-by-step explanation:
From the graph/image that you have provided said translated shift of
f(x) -> g(x)
f(x) = x^2 , g(x) = a(x -h)^2 +k
h is shift right/left
k is shift up/down.
It appears that the shift is left 2 and up 1.
h = -2 and k = 1
g(x) = (x - (-2))^2 +1
g(x) = (x + 2)^2 + 1

Answer:
One cubed shape block volume = 0.125 cubic feet
Step-by-step explanation:
Since the edge length of each block is 1/5 the edge length of the storage container, we do this:
1/5 x 2.5 = 0.5
Now we know that the edge length of each block is 0.5 feet. To find the volume of it, we do this:
0.5^3 = 0.125
The volume of one cubed shape block is 0.125 cubic feet.
