F(x)=2x^2+1 using the derivate definition

morpeh [17]

$\bf \stackrel{\textit{de} \textit{finition of a derivative as a limit}}{\lim\limits_{h\to 0}~\cfrac{f(x+h)-f(x)}{h}}\\\\
-------------------------------\\\\
f(x)=2x^2+1\implies \lim\limits_{h\to 0}~\cfrac{[2(x+h)^2+1]~~-~~[2x^2+1]}{h}
\\\\\\
\lim\limits_{h\to 0}~\cfrac{[2(x^2+2xh+h^2)+1]~~-~~[2x^2+1]}{h}
\\\\\\
\lim\limits_{h\to 0}~\cfrac{[2x^2+4xh+2h^2+1]~~-~~[2x^2+1]}{h}$

$\bf \lim\limits_{h\to 0}~\cfrac{\underline{2x^2}+4xh+2h^2\underline{+1}~~~~\underline{-2x^2-1}}{h}\implies \lim\limits_{h\to 0}~\cfrac{4xh+2h^2}{h}
\\\\\\
\lim\limits_{h\to 0}~\cfrac{2\underline{h}(2x+h)}{\underline{h}}\implies \lim\limits_{h\to 0}~2(2x+h)\implies \lim\limits_{h\to 0}~2(2x+0)\implies 4x$

For which of the following is x = -5 a solution? Select all that apply.

ser-zykov [4K]

Answer:

b. -x^2 + 50 = 25

c. |2x| = 10

d. x < 0

e. 2x < 10

Step-by-step explanation:

x = -5

-(-5)² + 50

-25 + 50 = 25

|2(-5)| = |-10| = 10

-5 < 0

2(-5) = -10 < 10

You sell tickets for a fundraiser. You give half of the tickets to your sister to sell. You sell 25 of your half of the tickets

hodyreva [135]

Answer:

84 tickets

Step-by-step explanation:

So first off lets add the tickets we sold to the tickets we have left. Lets x equal the amount of tickets we started with before selling.

25+17=x

Add them up.

42=x

We started with 42 tickets. To find how many tickets we had before spiting the tickets. We need to multiply our tickets by 2 since we had half. Let y be this number

42*2=y

Multiply them up

84=y

We started with 84 tickets.
