Answer:
Step-by-step explanation:
base = 784 sq in² 28 in tall pyramid
each side of the square base = √784 also equals 28
using the Pythagorean theorem the length of each side of the pyramid from the base to the point is
(side/2)² + height² =( length of the pyramid face)²
(28/2)² + 28² = 196 + 784 = 980 = (face length)²
face length = √980 = 31.3
area of the pyramid = 4 sides × area of each face + the area of the base
= 4×[(1/2)(base)(face length)] + side²
= 4(1/2)(28)(31.3) + 784
= 2537 sq in² Not in the solution set
F(x) = 2x+1
f(-4) = 2(-4)+1
= -8+1
= -7
i hope it helps
Answer:
Switch x and y.
Solve for x.
Function can be written as x²+4.
and last one will be 4.

Step-by-step explanation:
We have a work problem right here. We can use knowledge on ration and proportion to answer this type of problem. We do as follows:
1 job / 2 hours + 1 job / 3 hours = 1 job / time it takes for both when working together
time it takes for both when working together = 1.2 hours
I believe this is J with a radius of 6
the formula for circumference is 2(pi)r so i just took the 12(pi) and divided it by 2, which left me with 6(pi), meaning that 6 would be the "r" in the situation
