The negation isn't always true, as you can be unhappy while also not being hungry.

Greatest percent
cricket20 [7]

Answer:

Percent change from 15 to 18.

 

You need to divide the numbers, but which one goes on top?

 

You know the number increases from 15 to 18, so the percentage must be greater than 100%.

 

The only way to get a number greater than 100% is to put the larger number on top.

 

Therefore, the answer is 18/15 = 1.2

 

Multiply by 100 to get a %

 

1.2 * 100 = 120%

2. Calculate percentage change

from V1 = 5 to V2 = 8

ans= 60%

overall answer gain of 15 yards and 18 yards

The perimeter of the original rectangle is 16 feet. A small rectangle has a length of 6.2 feet and width of 1.8 feet. A larger r
GalinKa [24]

Answer:

  32 ft

Step-by-step explanation:

The length of the larger rectangle is double that of the smaller one. If we assume the rectangles are similar, the perimeter will be double as well:

  2·(16 ft) = 32 feet . . . . perimeter of larger rectangle

__

The width of the larger one is 2·1.8 ft = 3.6 ft.

CAN SOMEONE SHOW ME HOW TO DO THIS PLEASE????????????????

For (h+g)(x) you just add the two functions:

(h+g)(x) = 4x + 2x^2

For (h•g)(x) you multiply them:

(h•g)(x) = 4x • 2x^2 = 8x^3

For (h-g)(x) you subtract them:

(h-g)(x) = 4x - 2x^2


For (h-g)(-2) you sub -2 into the equation we just created:

(h-g)(-2) = 4(-2) - 2(-2)^2
(h-g)(-2) = -8 - 2(4)
(h-g)(-2) = -8 - 8
(h-g)(-2) = -16
