5. 53.96 - 19.99 = 33.97

33.97 / 53.96 = 0.629 = 63%

6. a 62% discount means she would pay 38% of the original price
   2.15 * 0.38 = 0.82 . the 0.82 is not the discount, but the amount she would actually pay.
 to check: the discount is 62%  2.15 x 0.62 = 1.33
2.15 - 1.33 = 0.82

If f(x) = x2 + 1 and g(x) = x – 4, which value is equivalent to mc024-1.jpg?
Harrizon [31]
The complete question in the attached figure

we have that
f(x) = x²<span> + 1
g(x) = x – 4

step 1
find </span>(f o g)(x)
(f o g)(x)= (x - 4)² + 1(f o g)(x) = x² - 8x + 16 + 1
(f o g)(x) = x² - 8x + 17

step 2
find (f o g)(10)
(f o g)(10) = 10² - 8*(10) + 17
(f o g)(10 = 100 - 80 + 17
(f o g)(10)= 37

the answer is 37
