Y=a(x-h)^2+k
-5=a(1-0)^2+2
-5=a+2
-3=a
y=-3x^2+2
V=a*b*c, a=(2+1/2), b=(2+1/2), c=(6+1/2)
V=(2+1/2)*(2+1/2)*(6+1/2) = 15/2 = 7+1/2
(seven whole and one second)
0.77 / 0.05 = 15.4 ...so we know it is 15 nickels
15 * 0.05 = 0.75.....0.77 - 0.75 = 0.02....with 2 pennies left over
ur answer is : 15 nickels and 2 pennies left over
Probably a C-, but it depends on how many other grades are in the gradebook and the exact percentage of your grade.
