Answer:

$445$

Step-by-step explanation:

$\text{Profit}=\text{Price}-\text{Cost}\\\text{Profit}=2.75-50=2.25\\\text{In order to make back the starting amount we need to sell n lots of widgets.}\\2.25n\geq 1000\\n\geq \frac{1000}{2.25}\\n\geq 444.444444\\\text{You can't sell a fraction of products, so you need to round it up to the nearest number.}\\n=445$

The aspect ratio of a TV screen is the ratio of the width to the height of the image. A regular TV has an aspect ratio of 16: 9.

ki77a [65]

Answer:

Width = 44.45 inches

Height = 25.00 inches

Step-by-step explanation:

(16x)^2 + (9x)^2 = 51^2

256x^2 + 81x^2 = 2601

337x^2 = 2601

x^2 = 7.718

x = 2.778

Width = 44.45 inches

Height = 25.00 inches

I think this is right

the function h(t)=-16t^2+110t+72 models the height h, in feet, of an object above ground t seconds after being launched straight

Anettt [7]

Answer:

The initial height of an object above ground before being launched straight up in the air

Step-by-step explanation:

we have

$h(t)=-16t^{2}+110t+72$

we know that

The number 72 represent the y-intercept of the function

The y-intercept is the value of y when the value of x is equal to zero

In this problem

The value of h when the value of t is zero

Therefore

The initial height of an object above ground before being launched straight up in the air
