Answer:
y = x² - 13x + 36
Step-by-step explanation:
Given the zeros x = 4 and x = 9, then the corresponding factors are
(x - 4) and (x - 9)
The polynomial is then the product of the factors
y = (x - 4)(x - 9) ← expand using FOIL
y = x² - 13x + 36
Trisha - 17 percent
Anchara - 4/25 = 0.16 = 16 percent
Juanita - 16 - 13.3 = 2.7 2.7/16 (since 16 is the total) = 0.16875 = 16.875 percent
So Trisha reduced her time by the greatest percent (17)
Answer:
C
Step-by-step explanation:
I did the math
Substitute x for whatever number is on the graph for x then do the math and get the answer for y and see if they are correct for each one.
Answer:
<em>b = 50√c</em>
Step-by-step explanation:
If b varies directly as the square root of c, this is expressed as;
b∝√c
b = k√c
k is the constant of proportionality
Given b = 100 and c = 4
100 = k√4
100 = 2k
k = 100/2
k = 50
Substitute k = 50 into the original expression:
Recall that: b = k√c
b = 50√c
<em>hence equation that can be used to find other combinations of b and c is b = 50√c</em>
