A ) This is a quadratic function:
y = a x² + b x + c
If the starting point is ( 0, 0 ) then c = 0
b ) The function is:
y = - 0.2 x² + 3.6 x
( with coefficients to the nearest tenth )
The graph is in the attachment.
c ) The roots:
x 1 = 0,
0.2 x = 3.6
x = 3.6 : 0.2
x 2 = 18d ) This is near the target ( 17 m ) . So the pumpkin
will hit near the target.

I think it would be set up as:
22/31=x/169
22*169 = 31x cross multiply
3718=31x now divide by 31
3718/31=119.94 ft = x or height of building
The cube root of 27 is 3 (3*3*3 = 27)
so if x^3 = 1/27
x = 1/3
Answer:
3x + 21
Step-by-step explanation:
(3)(x+7)
Now, we distribute the 3 in each term of (x+7)
So, 3*x = 3x and 3*7 = 21.
So our resulting term would be 3x+21.
