A semicircle has the radius of 2 4/5. What is its area? leave your answers in term of π

Ratling [72]

Answer:

$11\dfrac{13}{25}\pi$

Step-by-step explanation:

r = Radius of semicircle = $2\dfrac{4}{5}=\dfrac{24}{5}\ \text{units}$

Area of semicircle is given by

$A=\dfrac{\pi r^2}{2}\\\Rightarrow A=\dfrac{\pi \left(\dfrac{24}{5}\right)^2}{2}\\\Rightarrow A=\dfrac{288}{25}\pi=11\dfrac{13}{25}\pi\ \text{sq. units}$

The area of the semicircle is $11\dfrac{13}{25}\pi\ \text{sq. units}$ .

Solve this equation for x by graphing. -4x - 1 = 5^x + 4 Please help! Asap

Lina20 [59]

Answer:

-1.28

Step-by-step explanation:

You would put these two equations into a graphing ccalculator:

y = -4x - 1

and

y= 5^x + 4

Wherver they intersect is your answer.

These two happen to intersect at (-1.28,4.13)

Since the equation has x-values, you would give the first number (x-coordinate) as your answer.

The angles measures x and 4x are complementary angles. Which is the value of x?

Hitman42 [59]

Answer:

The angles measures x and 4x are complementary angles. The value of x is 36 degrees

Solution:

Given, two angles are x and 4x

We have to find the value of above given x

We are also given that, given two angles are complementary angles for each other

So, we know that, sum of any two complementary angles will always be equal to 180 degrees

Then, in the problem given,

$x+4 x=180 \rightarrow 5 x=180 \rightarrow x=\frac{180}{5} \rightarrow x=36$

Hence the angles measures x and 4x are complementary angles. The value of x is 36 degrees
