Answer:
cm
Step-by-step explanation:
As this problem is involving the adjacent and hypotenuse sides, we will be using the cosine function
We can setup an equation as follows

We can now solve for x

This rounds to

Answer:
21
Step-by-step explanation:
The average rate of change of function f(x) from x = a to x = b is

Here we have
a = -1
b = 2
f(a) = f(-1) = 1
f(b) = f(2) = 64





Answer:
See explanation below.
Step-by-step explanation:
He has to remember that b is the y-intercept and in this case it is 5 so he can automatically graph that point. Next, he has to recall that the number before the x is the slope and in this case it is -4 so he can use this to graph the line correctly.
Answer:
C. y = -3x +6
Step-by-step explanation:
y = mx + b
m= slope = -3
b = y-intercept = 6
y = -3x + 6
