profit=f(x)
so solve for f(x)=1000
1000=70n-400
add 400 to both sides
1400=70n
divide both sides by 70
20=n
20 students need to be enrolled to make a profit of 1000.00

Part 1
<span>(1,2) (3,4) (5,6), (-2,5) (-.6,7)} </span>
<span>This relation IS a function because none of the ordered pairs have the same first number. </span>
<span>Part 2 </span>
<span>{(1, 2), (1, 4), (3, 5)}. This relation is NOT a function because there are two ordered pairs, (1, 2) and (1, 4) with the same first element but different second elements. In other words, for the same inputs we must have the same outputs.</span>
Answer:
In Exercises 1-9, describe the transformation of f(x) = x² represented by g. ... 14. f(x) = 4x2 + 5; horizontal stretch by a factor of 2 and a translation 2 units up, ... graph of g be a horizontal shrink by a factor of the graph of f(x) = x2 x 2x ... 4(x-3)?–4.

Required
The perimeter of ABC
First, calculate the lengths of AC and BC.
From the attachment.
So, we have:
Also:
Recall that:
So:
So, we have:
To calculate BC, we have:
The perimeter is then calculated as:
