Write the quadratic function in vertex form. y=-3x^2+24x-50

castortr0y [4]

Answer:

Step-by-step explanation:

y = -3x² + 24x - 50

factor out leading coefficient

y = -3(x² - 8x) - 50

complete the square

coefficient of the x term: -8

divide it in half: -4

square it: (-4)² = 4²

use 4² to complete the square and keep the equation balanced:

y = -3(x² - 8x + 4²) + 3(4²) - 50

y = -3(x-4)² - 2

Lim x->-5(((1)/(5)+(1)/(x))/(10+2x))= correct answer 1/10x = -1/50 explain:

slava [35]

Given:

The limit problem is:

$lim_{x\to -5}\dfrac{\dfrac{1}{5}+\dfrac{1}{x}}{10+2x}$

To find:

The value of the given limit problem.

Solution:

We have,

$lim_{x\to -5}\dfrac{\dfrac{1}{5}+\dfrac{1}{x}}{10+2x}$

It can be written as:

$=lim_{x\to -5}\dfrac{\dfrac{x+5}{5x}}{2(5+x)}$

$=lim_{x\to -5}\dfrac{x+5}{5x}\times \dfrac{1}{2(5+x)}$

$=lim_{x\to -5}\dfrac{1}{5x\times 2}$

$=lim_{x\to -5}\dfrac{1}{10x}$

Applying limit, we get

$lim_{x\to -5}\dfrac{1}{10x}=\dfrac{1}{10(-5)}$

$lim_{x\to -5}\dfrac{1}{10x}=\dfrac{1}{-50}$

Therefore, the value of given limit problem is $-\dfrac{1}{50}$ .
