Answer:
C
Step-by-step explanation:
okay, this is actually pretty easy because it just works with simple translations.
(x+a)^2 + b
if a is positive, the graph shifts left
if a is negative, the graph shifts right
if b is positive, the graph shifts up
if b is negative, the graph shifts down
so since the quadratic, is starts at the origin and is shift 3 to the left, and 2 up:
the equation is
(x+3)^2 + 2
<span>With a boys to girls ratio of 8:7, this means 8/15 of the campers are boys and 7/15 of the campers are girls.
We are told that there are 195 total campers.
To find # of boys: 195 (the total # of campers) x 8/15 (fraction of the campers that are boys) = 104 boys
To find # of girls: 195 (total # of campers) x 7/15 (fraction of the campers that are girls) = 91 girls
Note: If you do not know how to multiply by fractions, let me know, I have another trick that takes more time but doesn't require the use of fractions.

Let
. Then
, and differentiating both sides with respect to
gives
Now, when
, you get
You have
, so
and
. So
What you have to do is look at all the measurements (ft) and they are labeled. And some of the sides that aren't labeled have clues of what they could be. So when I added, I got 78 ft for my answer.
