Answer:
Step-by-step explanation:
<u>Exponential function:</u>
<u>Ordered pairs given:</u>
<u>Substitute x and y values to get below system:</u>
<u>Divide the second equation by the first one and solve for b:</u>
- 80/10 = b³
- b³ = 8
- b = ∛8
- b = 2
<u>Use the first equation and find the value of a:</u>
<u>The function is:</u>
For this case we have the following quadratic functions:
Revenue:
Cost:
Then, we observe that the profit is given by the following mathematical relationship:
Substituting values we have:
Making the corresponding calculations we have:
Answer:
An expression that represents the profit is:
Answer:
d= 24
Step-by-step explanation:
-2= d/3 - 10
-6= d-30
-d=-30+6
-d= -24
d= 24
Answer:
The answer is option A
Step-by-step explanation:
Reflection in the y axis is
(x , y) → ( - x , y)
The coordinates of A are ( 2, -5)
When it's reflected in the y axis it becomes
( - 2 , - 5)
