Answer:
see below
Step-by-step explanation:
F(x) = 1,200x + 400
The y intercept is the value of the function when the x value is o
When x = 0 the y value is 400
It is the initial value of the function
Answer:
tanB=8/6
Step-by-step explanation:
Answer: 299 m/s
Step-by-step explanation:
The first step is to take the first derivative of the equation given. This will give us the equation for velocity which we will then substitute the 7 in for t.
To derive the equation you multiply the coefficient by the power of the variable, then subtract one from the variable.
v(t) = 6t^2 + 5
Now input 7 in for t to find the velocity.
v(7) = 6(7)^2 + 5
v(7) = 299 m/s
Answer: -83
Step-by-step explanation:
f(9)--22+20-9*(9)=-2-81=-83
