Find the area of the shaded regions.
Veronika [31]

Answer:

A = A_c-A_t=4\pi -8=4.5664cm^2

Step-by-step explanation:

The area of the shaded region can be calculated as the area of the semicircle less the area of the right triangle.

The area of the right triangle can be calculated as:

A_t=\frac{b*h}{2} =\frac{LM*MN}{2}

Where LM and MN have the same length because the internal angles are L=45°, M=90°, and N=45°. So the area is:

A_t=\frac{4*4}{2}=8

The diameter of the circle can be calculated using the Pythagorean theorem as:

D=\sqrt{(LM)^2+(MN)^2} =\sqrt{4^2+4^4}=4\sqrt{2}

So, the radius is r=2\sqrt{2}

Finally, the area of the semicircle is:

A_c=\frac{\pi*r^2 }{2}=\frac{\pi*(2\sqrt{2})^2  }{2}=4\pi

So, the area of the shaded region is:

A = A_c-A_t=4\pi -8=4.5664cm^2

The five numbers summary for a data set is shown below. What is the range of the data set? 3, 7, 11, 14, 16
scoundrel [369]

Answer:

13

Step-by-step explanation:

The range of a set of data is the difference between the highest and lowest values in the set.

So, in order to find the range, you first order the data from least to greatest. Which it is already.

3, 7, 11, 14, 16

Then subtract the smallest value from the largest value in the set.

16 - 3 = 13

Hope this helps you out! : )

Which equation represents a population of 370 animals that increases at an annual rate of 11% ?
Olegator [25]

The equation represents a population of 370 animals that increases at an annual rate of 11% is .

<h3>What is an exponential function?</h3>

It is defined as the function that rapidly increases and the value of the exponential function is always positive. It denotes with exponent y = a^x

where a is a constant and a>1.

Given that,

A population of 370 animals that increases at an annual rate of 11%

a = 370, r = 11%

p=a(1+r)^{t}

  = 370(1+0.11)^{t}

p  =  370(1.11)^{t}

Hence, The equation represents a population of 370 animals that increases at an annual rate of 11% is .
