1. Stocks of a company are initially issued at the price of 10 $. The value of the stock grows by 25 % every year. Show that the value of a stock follows a geometric sequence. a. Write a recursive formula that better describe that situation. b. Calculate the value of the stock ten years after the initial public offering. 2. Find the explicit equation of a geometric sequence such that u_3=18, and u_5=162. 3. Find the explicit equation of the arithmetic sequence such that u_1=3, and u_10=39.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a
