The y intercept is 9 and the unit rate is -7

So we plug these numbers in
y= -7x (the unit rate)+ 9 (y intercept)

y= -7x+9

If the price of theater tickets increases at 8% per year, about how long will it take to double the price?
Vladimir79 [104]

Answer:

9\ years

Step-by-step explanation:

Let

P----> the initial price of the ticket

y ---> the price of the ticket after t years

t---> the time in years

we know that

100%+8%=108%=108/100=1.08

so

y=P(1.08)^{t} ----> equation A

If the price is doubled

then

y=2P -----> equation B

equate equation A and equation B and solve for t

2P=P(1.08)^{t}

Simplify

2=(1.08)^{t}

Apply log both sides

log(2)=t*log(1.08)

t=log(2)/log(1.08)=9\ years

Steps:

32yd. * 15yd. = 480 sq. yd

96 sq. yd. + 480 sq. yd = 576

Description:

We know that the prism is 13 yards long with a base of 12 yards and height of 8 yards. Meaning.

H = height

B = Base

P= Prism

The area of the prism each is 12yd * 8yd/2 = 48. So the two triangle combined area will be 96 yd. Meaning we get the number 32yd times it by 8 divide by 2 = the answer will equal as 48yd .The perimeter of both identical, isosceles triangles triangles are 10yd. + 10yd. + 12yd. = 32yd. and the length of those sides is 15yd.  So the last step is to 32yd. * 15yd. = 480 sq. yd.  Now you combine the two areas yields the total . 96 sq. yd. + 480 sq. yd = 576 sq. yd. total Answer will come as 576. Meanign the correct answer for this question is 576 yd.

Answer:  576 sq. yd. total
