Answer:
45.27feet
Step-by-step explanation:
Given the height of the balloon (in feet) represented by the equation h=−16t2+28.7t+32.4, where t is the time (in seconds)
Note that the velocity of the balloon at maximum height is zero, hence;
v = dh/dt =0
-32t+28.7 = 0
-32t = -28.7
t = 28.7/32
t = 0.897secs
Get the maximum height
Recall that h=−16t²+28.7t+32.4
h = -16(0.897)²+28.7(0.897)+32.4
h= -12.87+25.74+32.4
h = 45.27feet
Hence the maximum height reached is 45.27feet
Answer:
x = 3
Step-by-step explanation:
3(2x + 5) = 33
3 * 2x + 3 * 5 = 33
6x + 15 = 33
6x = 33 - 15
x = 18 / 6
x = 3
At D point in the bottom then up and to the right upper corner to Letter B
The answer you are looking for is C my friend
The point-slope form:
m - slope
x₁, y₁ - the coordinates of a point
It passes through the points (1,-2) and (2,2).
