6 0

Answer:

4+2b=5+5b+20

<=> -3b=21

<=> b=-7

Step-by-step explanation:

<=> 4+2b=5+5b+5×4

<=> 4+2b=5+5b+20

<=> 2b-5b=5-4+20

<=> -3b=21

<=> b=-21/3

<=> b=-7

A ball is dropped from the ground. T represents the time in seconds. To find the time you can you the equation Y= -16t^2 +44t. H
bagirrra123 [75]

Answer:

2.75 seconds.

Step-by-step explanation:

We have been given that a ball is dropped from the ground. T represents the time in seconds.

To find the time when the ball was in air, we will equate height of ball with 0 and solve for t.  

-16t^2+44t=0

Upon dividing both sides by 4, we will get:

-4t^2+11t=0

-t(4t-11)=0

-t=0\text{ (or) }(4t-11)=0

t=0\text{ (or) }4t-11=0

t=0\text{ (or) }4t=11

t=0\text{ (or) }t=\frac{11}{4}

t=0\text{ (or) }t=2.75

Since our given function is a downward opening parabola, so ball will be in air between both t-intercepts.

Since the ball touches the ground at 2.75 seconds, therefore, the ball would be in air for approximately 2.75 seconds.

The length of the box is 2x - 2 and the width is x - 5. Find the perimeter. (HINT: p= 2L + 2W) Choose one.
trasher [3.6K]

Answer:

Option D: 6x-14 is the correct answer.

Step-by-step explanation:

Given that:

Length of the box = L = 2x-2

Width of the box = W = x-5

Perimeter is defined by the sum of length of all sides of the box.

Perimeter of the box = P = 2L + 2W

Perimeter of box = 2(2x-2) + 2(x-5)

Perimeter = 4x-4+2x-10

Perimeter = 6x-14

The perimeter of the box is 6x-14.

Hence,

Option D: 6x-14 is the correct answer.
