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

$Cost = ($0.09)(3.14)(9*9)(9.5) = $217.4607
Answer:
The answer is 36.20 :)
Step-by-step explanation:
Factor out a 3x:
3x(x2+4x+6)
Since you can't factor out the quadratic that's as far as it goes:
Answer:
3x(x2+4x+6)
Answer:
The standard equation for an ellipse, x 2 / a 2 + y2 / b 2 = 1
Step-by-step explanation:
it represents an ellipse centered at the origin and with axes lying along the coordinate axes.
