Answer:
We solve the equations g + e = 117 and e / g = 2 / 7; where g = number of gas mowers and e = number of electric mowers;
So, g = 117 - e and 2g = 7e;
Then, 2( 117 - e ) = 7e;
234 - 2e = 7e;
234 = 9e;
e = 234 ÷ 9;
e = 26;
g = 117 - 26;
g = 91;

<u>First Derivative</u>
Given a real continuous function f(x), the first derivative f'(x) represents the slope of the tangent line for any value of x.
If the slope of the line is positive, then the function is increasing, if the slope of the line is negative, the function is decreasing.
The function to analyze is:
Computing the first derivative:
The function will be increasing when:
Dividing by 2:
Solving:
x > 1
This solution is represented by the interval (1,∞)
Correct answer: C. (1,∞)
Answer:
a = - 3.8, b = - 2.6, c = 1.7, d = 4.4 and e = 1.0
Step-by-step explanation:
Let us assume y = g(x) and y = h(x) are inverse of each other, where g(x) and h(x) are two different functions.
Then if a = g(b) then b = h(a).
Now, in the given table, a = - 3.8, b = - 2.6, c = 1.7, d = 4.4 and e = 1.0
Therefore, for those values of a, b, c. d and e the table in black will be an inverse function of the table in red. (Answer)
