Answer:
<h2>(g-f)(10) = - 71</h2>
Step-by-step explanation:
f(x) = x² - 1
g(x) = 2x + 8
To find (g-f)(10) first find ( g - f)(x)
To find ( g - f)(x) subtract f(x) from g(x)
That's
( g - f)(x) = 2x + 8 - ( x² - 1)
Remove the bracket
( g - f)(x) = 2x + 8 - x² + 1
Simplify
( g - f)(x) = - x² + 2x + 9
To find (g-f)(10) substitute the value in the bracket that's 10 into ( g - f)(x)
That is
(g-f)(10) = -(10)² + 2(10) + 9
= - 100 + 20 + 9
= - 100 + 29
= - 71

Answer:
AC = 52.8
Step-by-step explanation:
33/20 = 1.65
12*1.65 = 19.8
BA = 19.8
CB + BA = AC
33 + 19.8 = 52.8
So Roger flight left at exactly 9.27:am and it will land at 1:05pm
So count on to 12:27 will be 3 hours and subtract from 5 because 65 is 05 3hours and 38mins
You would have to divide 37.2 by 10. The answer would be 3.72.
