A ball is thrown from a height of 45 meters with an initial downward velocity of 10 m/s. The ball's height h (in meters) after t

dmitriy555 [2]

Answer:

2.16 s

Step-by-step explanation:

When it hits the ground, height h=0 hence

$0=45-10t-5t^{2}$

$5t^{2}+10t-45=0$

$t^{2}+2t-9=0$

Using quadratic formula

$x=-1+\sqrt 10\\ x=-1-\sqrt 10$

Since time can't be negative, $-1+\sqrt 10$

t=2.16 s

What are two different way of factoring -3x-9? Select all that apply

Ghella [55]

Options:

A. –3(x + 3)

B. 3(x + 3)

C. 3(–x – 3)

D. –3(x – 3)

Answer:

A and C

Step-by-step explanation:

Given

$-3x - 9$

Required

Factorize

The options are not given; So, I'll answer on a general term

$-3x - 9$

Express -9 as -3 * 3

$-3x - 9 = -3x - 3 * 3$

Then factorize 3 out of the expression as:

$-3x - 9 = 3(-x - 3)$

Another way is to factor -3 out of the expression as:

$-3x - 9 = -3x - 3 * 3$

$-3x - 9 = -3(x + 3)$
