In 1999, the share price for General Motors stock was $144 per share but has been declining at an average rate of 14% per year.
vodomira [7]

Answer:  $5.22  (in the year 2021)

========================================================

Explanation:

The year 2021 is 22 years after 1999 since

2021 - 1999 = 22

That means we'll plug x = 22 into the equation given to us

P = 144*(0.86)^x

P = 144*(0.86)^22

P = 5.21588994768589 which is approximate

P = 5.22 rounding to the nearest cent

The share price is about $5.22 in the year 2021.

This assumes that the 14% decline keeps happening year after year; however, in reality, stocks are more complicated and fluctuate more randomly if anything.

Vinvika [58]

Answer:

64

Step-by-step explanation:

(3x+5)^2 = ax^2 +bx+c

FOIL the left side

(3x+5) (3x+5)

9x^2 +15x+15x+25

Combine like terms

9x^2 +30x+25

a=9

b= 30

c= 25

a+b+c = 9+30+25 = 64
