The population of detroit, michigan has declined 20% every decade since 1950. In 2010, there was a population of 713,000. Please help with the following questions:
-Does this situation describe growth or decay? a. Growth b. Decay
-What is the rate of this growth or decay? a. 2 b. 0.80 c. 0.20 d. 0.02
-Write an equation to represent the situation. a. y= 713000(0.20)x b. y = 713000(1+0.2)x c. y = 713000(20)x d. y = 713000(1 -0.2)x
-If the trend continues, what will the population be in 2040? (Hint: how many DECADES is this?) a. 883 b. 142,600 c. 365,056 d. 570,400
- What was the population in 1990? (Hint: how many decades AGO was this?)
a.61,842,892 b.1,114,063 c.570,400 d.285,200

b. hoped i'm right lol

step-by-step explanation:

8

step-by-step explanation:

moderators are

part a: triangles gcb and epb

part b. sides cg and rp are parallel by definition of parallelogram.

angles cgb and e are congruent by being alternate interior angles of parallel lines cut by a transversal. angles gbc and ebp are congruent because they are vertical angles. by aa similarity, the triangles are similar.

part c. since the triangles are similar, the ratios of the lengths of corresponding sides are equal.

calculation of be:

gb/be = cb/bp

(400 ft)/be = 300/200

(400 ft)/be = 3/2

3be = 2 * 400 ft

3be = 800 ft

be = 800/3 ft

calculation of pe:

gc/pe = cb/bp

(350 ft)/pe = 300/200

(350 ft)/pe = 3/2

3pe = 2 * 350 ft

3pe = 700 ft

pe = 700/3 ft
