Answer:
Step-by-step explanation:
A(4;1) B(1;3)
●use distance formula (see photo^)
First we have to work out the area of the trapezoid using the formula;
1/2 (a+b) h
The height is 16ft, and a = 24ft, and b = 15ft
Put this into the formula
1/2 (24 + 15) 16
1/2 39 * 16
39 * 8 (you can halve the 16)
= 312 ft squared
Now we simply multiply the area by the cost per square foot to get our answer.
312 * 0.79 = $246.48
Answer:
a) 0≤x≤100 ; 0≤y≤300
Step-by-step explanation:
Here we are given that
x is the number of out state students
y is the number of in state students
Also , the number of in state students are 3 times that of out state students. Hence
y=3x
Now . we are given with the condition that the maximum space for the out state students is 100.
Hence
x≤100
or
0≤x≤100
Multiplying all three sides with 3 we get
0≤3x≤300
0≤y≤300
Hence we have our required constraint for the in state and the out state students.

See attachment.
The change from x to (x-4) moved the function to the right by 4. The - 5 moved it down by 5 (as measured from the crossover/inflection point.
