Answer:
2 quarters and 15 dimes
Step-by-step explanation:
15 dimes = $1.50
2 quarters = $0.50
$1.50+$0.50=$2.00
Answer:
A' ( 2, 4) and B' ( -4, 0)
Step-by-step explanation:
A ( -2, 4) and B( 4,0) reflected over the y-axis
A' ( 2, 4) and B' ( -4, 0)
the y-coordinate do not change and the x is opposite sign
(x,y) reflected over y-axis (-x, y)
Answer:
a) see below
b) 40x20 meters
Step-by-step explanation:
Write down what you know:
- The area of the enclosure is length*width, so

- The length of the fencing is 80 meters, so

Now we have to combine these two equations above, and get rid of y in the process.
First rewrite the second as:

Then substitute for y in the first:

b) To maximize A, find the zero of the first derivative:

So y = (80-40)/2 = 20 meters.
Answer: All i know is you have to multiply all of those numbers because its area
