Answer:
f(x) = 11x -15
Step-by-step explanation:
Often, we let x represent the input to a function. When that is multiplied by 11, the result is represented by 11x. If 15 is subtracted from that, then the expression becomes ...
11x -15
If this value is the output of function f, we write this as ...
f(x) = 11x -15
First one is -3
Second one is 1

Acceleration of stone = 10
Integrate:
So velocity = 10t
Integrate again:
So distance from starting point = 5t^2
Distance from ground = 450-5t^2
b)
450 - 5t^2 = 0
9.48 seconds
c) velocity = 10t
Put the time into this to give:
94.8 m/s
d.
Velocity = 10t + 5
Integrate again:
5t^2 + 5t
Solve
5t^2 + 5t = 450
Gives 9 seconds</span>
A. h = 30Ft * 1.26cm/Ft = 37.8 cm. = Ht. of the model.
37.8cm * 1toothpick/6.3cm = 6 Toothpicks
B. 37.8cm/7.6 = 4.97 hope this helped.
