Answer:
se the function to determine the shot's maximum distance. Occurs when f(x) = 0 : -0.01x^2+0.7x +6.1. = 0. Use the quadratic formula
Step-by-step explanation:
Answer:
Step-by-step explanation:
it is maximum.
when leading coefficient of x² is negative,
It is downward parabola.
or
y=-2x²+10x+1
=-2(x²-5x+(-5/2)²-(-5/2)²)+1
=-2(x-5/2)²+2×25/4+1
=-2(x-5/2)²+25/2+1
=-2(x-5/2)²+27/2
maximum value of y is 27/2 and is attained at x=5/2
vertex is (5/2,27/2)
-13k + 7k - 4 = 23 + 16k - 2
-13k + 7k - 16k = 23 - 2 + 4
-22k = 25
k = 25/-22
If there’s an 80 percent reduction then you’re paying 20 percent of the original cost.
132 =.2x
X =$660
First, 10 goes into 47, 4 times.
4 is your whole number.
10 x 4 = 40
47 - 40 = 7
then put 7/10
Put them together and your answer will be (4 7/10)
