In order to find the turning point, you need to find the rate of change of the slope.

At the turning point, the slope will be 0.

So, you should take the derivative of T(x): 

T(x)' = 3(x+5)^2, you will see only when x = -5, T(x)' = 0

So when x < -5, T(x)' >0, and x>-5, T(x)' > 0 as well

Therefore, the turning point is unique: x= -5

A company's revenue function and cost function are as follows: R(x) = 0.55x and C(x) = 10 + 0.05x. What is the minimum number of
Oduvanchick [21]

Answer:

Minimum number of units sold to make profit is equal to 20

Step-by-step explanation:

Revenue earned by the company as a function of number of units sold as x:

R(x) = 0.55x

Cost for selling units as a function of number of units sold as x:

C(x) = 10 + 0.05x

<em>Net profit earned by the company = (Revenue earned by the company) - (Cost of selling units)</em>

P(x) = (0.55x) - (10 + 0.05x)

P(x) = 0.55x - 10 - 0.05x

P(x) = 0.5x - 10

To earn profit the following condition should satisfy: P(x) ≥ 0

0.5x - 10 ≥ 0

0.5x ≥ 10

x ≥ \frac{10}{0.5}

x ≥ 20

slavikrds [6]

Answer:575 and 1 extra tile

Step-by-step explanation:if the total tiles is 5,176 which will be used in 9 floors .We will divide the total tiles by the floors .Therefore we will get 5176 /9 =575.111

Therefore each floor will have 575 tiles

To get the remaining tiles

575*9 = 5175 which gives us a remainder of 1 tile when you subtract the total 5176 -5175 =1
