A car salesman's total salary, s, is a base salary plus a commision. The salesman has a base salary of $25,00 and receives a com
Archy [21]
The equation that best represents the total earnings for the salesman is letter c which is e=40,000+200 xc

It is because, in order to get the full earnings, you have to add the base salary to the commission that the salesman receives. Whereas, the $40,000 is attached to the commission where the $200 is multiplied to c (every car the salesman sells

Let f(x) = (x − 3)−2. Find all values of c in (1, 7) such that f(7) − f(1) = f '(c)(7 − 1). (Enter your answers as a comma-separ
Sidana [21]

Answer:

This contradicts the Mean Value Theorem since there exists a c on (1, 7) such that f '(c) = f(7) − f(1) (7 − 1) , but f is not continuous at x = 3

Step-by-step explanation:

The given function is

f(x)=(x-3)^{-2}

When we differentiate this function with respect to x, we get;

f'(x)=-\frac{2}{(x-3)^3}

We want to find all values of c in (1,7) such that f(7) − f(1) = f '(c)(7 − 1)

This implies that;

0.06-0.25=-\frac{2}{(c-3)^3} (6)

-0.19=-\frac{12}{(c-3)^3}

(c-3)^3=\frac{-12}{-0.19}

(c-3)^3=63.15789

c-3=\sqrt[3]{63.15789}

c=3+\sqrt[3]{63.15789}

c=6.98

If this function satisfies the Mean Value Theorem, then f must be continuous on  [1,7] and differentiable on (1,7).

But f is not continuous at x=3, hence this hypothesis of the Mean Value Theorem is contradicted.

Solve the equation <br>50=4(x-7)-6(3x-6)
rusak2 [61]

we are given

50=4(x-7)-6(3x-6)

Firstly , we can distribute

50=4x-28-18x+36

now, we can combine like terms

50=-14x+8

-14x=42

now, we can solve for x

and we get

x=-3...........Answer
