Answer:
Step-by-step explanation:
I figured this out with calculus since it's easier that way. The position function for the ball is
. The first derivative of position is velocity, so we need to find the first derivative of the position function which is
v(t) = -32t + 64
Now, where the ball is at its highest point is where the velocity is equal to 0, so setting the velocity function equal to 0 allows us to determine how many seconds it takes to get to that max height.
0 = -32t + 64 and
-64 = -32t so
t = 2 seconds. It takes 2 seconds to get to its max height. In order to determine that max height, we sub 2 in for t in the position function:
and
s(2) = 66 feet. The max height of the ball is 66 feet.
Answer:
Amanda found the equation 10x+5y=20 in the “linear equations” chapter of her math book.
Step-by-step explanation:
Amanda found the equation 10x+5y=20 in the “linear equations” chapter of her math book.
Slope form y2-y1 / x2-x1 = m
20 - 9 = 11
12 - 4 = 9
The slope of the line is 11/9
Answer:The better option would be the $6.75 per square foot plus a $100 fixed installation fee.
Step-by-step explanation:
B1= 330 ft
B2= 180 ft
B3= 156 ft
Total sq is 666
666 * 6.75 + 100= $4,595.5
666 * 7.25= 4,828.5
