The function f(t) = 750t + 20,000 models the number of movie theaters in the United States t years after 1985. Use this equation

Alexandra [31]

Given:

The function models the number of movie theaters in the United States t years after 1985.

$f(t)=750t+20,000$

To find:

The year in which the United States will have 35,000 movie theaters.

Solution:

We have,

$f(t)=750t+20,000$

Putting f(t)=35000, we get

$35,000=750t+20,000$

$35,000-20,000=750t$

$15,000=750t$

Divide both sides by 750.

$\dfrac{15,000}{750}=t$

$20=t$

It means, United States will have 35,000 movie theaters 20 years after 1985.

$1985+20=2005$

Therefore, United States will have 35,000 movie theaters is 2005.

I WILL GIVE BRAINLIST!!<br> Showthat (2x+i)(2x−i) = 4x2 +1

kherson [118]

(2x + I) (2x-I) = 4x^2 + 1

Using the complex arithmetic rule:

(A + bi)(a-bi) = a^2 + b^2

A would be the 2x and b would be the i

So you would have:

(2x)^2 + (i)^2

(2x)^2 = 2x times 2x = 4x^2

i ^2 = 1

Final answer is 4x^2 + 1
