What is the area of the trapezoid ?
Helga [31]

Answer:

<h2>432 ft²</h2>

Step-by-step explanation:

The formula of an area of a trapezoid is:

A=\dfrac{b_1+b_2}{2}\cdot h

<em>b₁, b₂</em><em> - bases</em>

<em>h</em><em> - height</em>

<em />

We have:

<em>b₁ = 20 ft, b₂ = 16 ft, h = 24 ft</em>

Substitute:

A=\dfrac{20+16}{2}\cdot24=\dfrac{36}{2}\cdot24=18\cdot24=432\ ft^2

Write an equivalent exponential equation for:<br> <img src="https://tex.z-dn.net/?f=log_%7B2%7D%20%28%5Cfrac%7B1%7D%7B4%7D%20%29
Kisachek [45]

Answer: \frac{1}{4}=2^{(-2)}

Step-by-step explanation:

You know that an expression written is logarithmic form is:

x=log_b(y)

And an expression equivalent to the expression above that is written in exponential form is:

y=b^x

Therefore, keeping the information above on mind, you have that an equivalent exponential equation for log_{2}(\frac{1}{4}) =-2 , is the shown below:

\frac{1}{4}=2^{(-2)}

Find Volume for the cones. Round to the nearest TENTH. (A) Radius of 2 in, and a height of 4 inches (B) Diameter of 6 m, and a h
Aleksandr-060686 [28]

Answer:

A. 16.8 in³

B. 28.3 m³

C. 65.4 in³

Step-by-step explanation:

The volume of a cone is given as:

V = ⅓ * pi * r² * h

Where r = radius of base of cone

h = height of cone

A. Radius = 2 inches, height = 4 inches

It's volume is:

V = ⅓ * pi * 2² * 4

V = 16.8 in³

B. Diameter of 6 m, and a height of 3 m

It's diameter is 6 m, therefore, it's radius is:

r = d / 2 = 6 / 2 = 3 m

It's volume is:

V = ⅓ * pi * 3² * 3

V = 28.3 m³

C. Diameter of 5 in, and a height of 10 in

It's diameter is 5 in, therefore, it's radius is:

r = d / 2 = 5 / 2 = 2.5 m

It's volume is:

V = ⅓ * pi * 2.5² * 10

V = 65.4 in³
