Answer:
a) 17.5
b) 15.6
c) 13.3
d) 21.51
Step-by-step explanation:
The given function is equal to:
f(x)=kx^2
where

where y=23
Clearing k=0.00025
a) 
b)
c) The function is equal to:
f(x)=k(1+2x)

where y=20
k=0.0024

d) 
The correct answer is C.) (y|y > -4).
In order to find the range, we look for the possible numbers that y can be. In this case, you'll see the lowest the number goes is -4 and it continues up forever. Therefore, the answer is that y has to be greater than -4.
Answer:
i would say its b
Step-by-step explanation:
This is Newtons second law of motion
Force = mass * acceleration
so here we have:-
10 = 10 * a
a = 1
its acceleration is 1 meter / sec^2.
