Since the equation is in slope-intercept form, we know from the definition of slope-intercept form that 6 is the y-intercept.
Answer: It represents the area of the two circular sides ("lids")
Explanation:
Imagine you made a cylinder out of 3 pieces of paper. The cylinder can be decomposed into two circular shapes (radius r) and one rectangular piece with two side lengths: one is "h", the other has to be long enough to go around each of the disks, so it has to be 2*pi*r long.
So the term 2*pi*r*h is the area of the rectangular piece and pi*r^2 is the area of each of the "lids" Since there are two of those, the term 2*pi*r^2 represents the area of the bottom and top lids.
Answer:
B
Step-by-step explanation:
I chose the answer B because there is no there should be no exponents to make the answer linear
Answer:
3.63 meter/sec²
Step-by-step explanation:
When a rock fall from a height h with initial velocity u and the rock reaches the surface in t seconds the expression that represents this is
h = 4t + 
gt²
Where g is the acceleration due to gravity
Here h = 0.72 meters
u = 0
t = 0.63 seconds
from the given formula
0.72 = 0 ×(0.63) + g(0.63)²
0.72 = g(0.63)²
g = 
= 3.63 meter/sec²
