Answer:

$73,564,723.80

Step-by-step explanation:

"x is the number of years after the expansion in 2005"

This year is 2021.

2021 - 2005 = 16

x = 16

f(x) = 12(1.12)^{x}

f(16) = 12(1.12)^{16}

f(16) = 73.56

Jason is building a 1 : 180 scale model of a real castle. his model has a rectangular base that is 3 feet wide and 4 feet long.w
balu736 [363]
The area of the actual castle would be 388,800 sq. ft.

We would multiply each of the sides of the scale model both by 180 to find the side lengths of the actual castle.

So...
180 x 4 = 720
180 x 3 = 540

If Area is equal to Length Times Width, all thats left to do is to multiply the two sides together.

720 x 540 = 388,800

Hope this helped! :D

HURRRRYYY <br>Hurry pleaseee use elimination show your work <br><br><br>15y - 9x =-9 -8y+9x=12
Nastasia [14]
Add the two functions together to get

7y=-3
y=-3/7

Then plug in y to either function to solve for x, I’ll just use the left one

15(-3/7)-9x=-9
-45/7-9x=-9
-9x=-18/7
x=18/7/9

x=2/7
