Answer:
Step-by-step explanation:
Law of Cosines
x = √(40²+12² - 2·40·12·cos(37°)) ≅ 31.3 units
The difference quotient of the function that has been presented to us will turn out to be 5.
<h3>How can I calculate the quotient of differences?</h3>
In this step, we wish to determine the difference quotient for the function that was supplied.
To begin, keep in mind that the difference quotient may be calculated by:
Lim h->0 
Now, for the purpose of the function, we need this:
Then we will have:

j(x) = 5x - 3
Then the following will be true:
Therefore, 5 is the value of the difference quotient for j(x) is %

Answer:
One
Step-by-step explanation:
(x + 12) = 4x - 1
x + 12 = 4x - 1
12 = 3x - 1
13 = 3x
x = 13/3 = 4.3333333...
Since x only has one value, only one solution exists for the equation.
F(-3.29) = (-3.29) + 2.58
f(-3.29) = -0.71
