Answer:
Angle C = 142 degrees
Step-by-step explanation:
A+B = 90
B+C = 180
Rearrange first equation to get B = 90-A
Plug this into the second equation:
90-A + C = 180
C = A + 90
Plug in A, C = 52 + 90 = 142
Answer:
-7 degrees
Step-by-step explanation:
The temperature is predicted to be ...
5 +3(-4) = 5 -12 = -7 . . . . degrees
__
To find the change, multiply the rate of change by the time period. To find the new temperature, add the change to the starting temperature.
Answer:
The profit function is:

The maximum value is 406, 300 occurring when x = 640.
Step-by-step explanation:
The revenue function is:

And the cost function is:

Then the total profit function will be:

This is a quadratic function.
Therefore, the maximum value of the total profit will occur at its vertex point.
The vertex of a quadratic is given by:

In this case, a = -1, b = 1280, and c = -3300.
Then the point at which the maximum profit occurs is at:

And the maximum profit will be:

Answer:
.

Answer:
The slope- intercept form this situation is given by y = 0.75x + 3 .
Step-by-step explanation:
The slope- intercept is given by
y = mx + c
Where m is the slope, c is the y intercept .
As given
When visiting Baltimore, MD needs taxi to get from your hotel to the National Aquarium.
The taxi company charges a flat fee of $3.00 for using the taxi and $0.75 per mile.
Let us assume that the total amount charge by the taxi be y .
Let us assume that the number of miles travelled by the taxi be x.
Than
Total amount charge by taxi = Amount charge by the taxi per miles + Flat free charge .
y = 0.75x + 3
(Here m = 0.75 and c = 3)
Therefore the slope- intercept form this situation is given by y = 0.75x + 3 .
