Answer:

Step-by-step explanation:

"The Winner." who is Jane, with 70% of the votes, received:

70% of 60 votes

The word "of" usually means multiply.

70% may also be written as 0.70 and as 70/100 (you may choose the one to use)

Let's use (70/100):

(70/100)*60 = 4200/100 = 42 votes

This is just a math equation. Just add 12 1/2 to 1 2/5 and remember that the bottoms of fractions have to be the same and if you change the bottoms, you have to change the top just as much :)

$\large\boxed{f'(2) = -\frac{16}{27} }$

$f'(x) = \frac{(5 + x^{2} )(-2x) - (7 - x^{2} )(2x)}{(5+x^{2})^{2} } \\\\f'(x) = \frac{-10x-2x^{3}- 14x + 2x^{3} }{(5+x^{2})^{2} } \\\\f'(x) = \frac{-24x}{(5+x^{2})^{2} }\\\\ \text{Solve for the derivative at f'(2) using substitution:}\\\\f'(2) = \frac{-24(2)}{(5+2^{2})^{2} } \\\\f'(2) = \frac{-48}{81} \\\\\text{Simplify:}\\\\f'(2) = -\frac{16}{27}$

1. Find a if x³ + ax² - x -8 is divisible by x -1

Amanda [17]

Answer:

a = 8

Step-by-step explanation:

x-1 = 0

x = 1

let x³ + ax² -x -8 be p(x)

hence, p(1) = (1)³ + a(1)² -1 -8 = 0 (since, x-1 is a factor)

= 1 + a - 1-8

= a - 8 = 0

therefore, a = 8
