Answer:
The equation in vertex form is:
Step-by-step explanation:
Recall that the formula of a parabola with vertex at 
is given by the equation in vertex form:
where the parameter 
can be specified by an extra information on any other point apart from the vertex, that parabola goes through.
In our case, since the vertex must be the point (2, 1), the vertex form of the parabola becomes:
we have the information on the extra point (0, 5) where the parabola crosses the y-axis. Then, we use it to find the missing parameter 
:
The, the final form of the parabola's equation in vertex form is:

cos (B) = 3/(3sqrt(2))
B = cos ^-1(3/(3sqrt(2)))
B = 45 degrees

The independent variable is the number of sweatshirts sold so it is answer A.
(Money raised is the dependent variable because it depends on the number of sweatshirts sold.)
Answer:
320 cents per pound
or
$3.20 per pound
Step-by-step explanation:
Divide dollars by pounds
$9.60/3 = $3.20 per pound
Since it asks for the price of candy in cents per pound, multipy 3.20 by 100.
3.20 x 100 = 320 cents
320 cents per pound.
