Given the function y=1200x(1+0.3)^t . Does the function represent exponential growth or exponential decay? What is the rate of growth or rate of decay? a. Exponential decay and has a decay rate of 3%

b. Exponential growth and has a 3% growth rate

c. Exponential decay and has a decay rate of 30%

d. Exponential growth and has 30% growth rate

f

step-by-step explanation:

f

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

answer:

your answer is: c. 196 7/8 in^3.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
