The Pharaoh builds a square pyramid which is 20 feet on one side, with a height of 36 feet. Find the pyramid's volume. ANSWERS:

loris [4]

Answer

4800 ft3

Step-by-step explanation:

Formula for volume of a pyramid is 1/3*base*hight

because you do 20*20=400ft2 for the base

Then you times 36 (the hight) by 1/3 and get 12

Then you do 400*12=4800ft3 theres your answer

hope this helps

In one region, the September energy consumption levels for single-family homes are found to be normally distributed with a mean

Genrish500 [490]

Answer: The required probability is 0.68793.

Step-by-step explanation:

Since we have given that

Mean = 1050 kWh

Standard deviation = 218 kWh

n = 50

$P(X>1065)=P(z>\dfrac{1065-1050}{\dfrac{218}{\sqrt{50}}}\\\\P(X>1065)=P(z>\dfrac{15}{30.83})\\\\P(X>1065)=P(z>0.486)=0.68793$

Hence, the required probability is 0.68793.

substitute the given values

4x+10=5x+5

solve for x

5x-4x=10-5

x=5

Find the value of UV

UV=5x

substitute the value of x

UV=5(5)=25 units

Please look at the picture and help me with this question

adoni [48]

Answer:

Step-by-step explanation:

f(x) = 4^x

g(x) = f(x -1) + 3

g(x) = 4^(x - 1) + 3

See the diagram that is below.

Red line: f(x) = 4^x

Blue line: g(x) = f(x - 1) + 3

The graph has been transformed so that f(x) moves upwards by 3 unitsw to get to g(x)

Furthermore, if x = 0 the y intercept for f(x) = 1

If x = 0 then g(x) moves up 3 spaces by virtue of the 3, and and up another 1/4 because the first term becomes 4^-1 = 1/4. This 1/4 gets added to the 3 to give 3 1/4
