Evaluate the exponential function.

Mathematics
1 answer:
kakasveta [241]4 years ago

Hey there!

Our function is:

f(x) = 4^x

If we want to have f(3), we simply can plug in 3 to our answer, and evalutate from there:

f(x) = 4^3 =
4*4*4 =
16*4 =
64

We just calculated 4 to the fourth power, which is four times four times four times four. Therefore, 4 of four is equal to 64.

Hope this helps!

Help me please! I need to find the answer for the angle indicated in bold!
bagirrra123 [75]

(x+ 63) + (x + 133) = 180 \\ 2x + 196 = 180 \\ 2x =  - 16 \\ x =  - 8 \\ so... \\ x + 133 = ( - 8 ) + 133  \\  = 125

Which expression is equivalent to 2 (14x-37+28x+12.2-5y-17.5)?
ziro4ka [17]

Answer:

A. 84x - 16y - 10.6

Explanation:

\sf \rightarrow 2(14x-3y+28x+12.2-5y-17.5)

\sf \rightarrow 2 (42x-8y-5.3)

apply distributive method: a(b + c) = ab + ac

\sf \rightarrow 2 (42x) -2(8y)-2(5.3)

\sf \rightarrow 84x -16y-10.6

The sphere area of a sphere is 200.96 square centimeters. What is the approximate volume of the sphere? Use 3.14 for pi. Round y
julsineya [31]

We are given

area of sphere is 200.96cm^2

it means that we are given surface area

so, we can use surface area formula

S=4\pi r^2

where S is surface area

r is radius

so, firstly we need to find radius or r

200.96=4\pi r^2

we can solve for r

r=3.9989cm

now, we can find volume

V=\frac{4}{3} \pi r^3

we can plug r

V=\frac{4}{3} \pi (3.9989)^3

now, we can find volume

V=267.86cm^3.............Answer

A trapezoid has an area of 13.5 square inches. If the bases are 3 and 6 inches what is the height?
liraira [26]
Well the formula is : b1+b2/2 (h)

so the height would be solved as : 
13.5 = 3+6/2 (h)
13.5 = 9/2 (h)
h = (13.5)/(9/2)
h = (13.5) x (2/9)  *reciprocal*
h = (27) / (9)
h = 3
