Answer:
A-1
Step-by-step explanation:
18-4x=7x+7
18=11x+7
11=11x
x=1
The height of the fireworks from the ground is f(t) =
Given that the fireworks will now be launched from the top of a 120-foot-tall building.
In general, the height function h(t) = –16t^2 + v0t + h0
V0- is the initial velocity, h0 is the initial height
Initial velocit = 224
Initial height = 120
So the new function g(t) =
Original function f(t) =
New function g(t)=
In original function f(x), the firework is launched from the ground so the initial height is 0.
In new function g(x), the firework is launched from the top of a 120-foot-tall building so the initial height is 120.Hence 120 is added with f(x) to get g(x).
Answer:
the answer is b
Step-by-step explanation:
Answer: -1
Step-by-step explanation:
If k is equal to negative one then we can input it into it for the exponent and solve.
If multiplying exponents and they have the same base then you will just add the exponents and let the exponents stay the same.
The exponents are -3,1, and -1 add them.
-3 + 1 - 1 = -3
The base is 10 so we will raise 10 to the negative 3rd power.
