So an exponential equation is gonna be used for this problem. The formula for such is
, in which the a variable is the initial value and the b variable is the growth/decay rate.
For this situation, 1200 is gonna be your a variable since you've started out with it. And as for your b variable, its gonna be 107.3%, or 1.073, since it's increasing.
Your equation should look like this:
and from here just plug in 10 into the x variable and solve.
Multiply (1.073)^10 (don't round answers until the end), and take that answer and multiply it with 1200, your answer should be $2427.61.
Answer:
Exact form:
Decimal form:
x= -8.5
Step-by-step explanation:
For point with coordiantes (x,y), the abscissa is the x-coordinate and the ordinate is the y-coordinate. So, all you have to do is match the given x values with the second term inside the parenthesis. Also, the x values must also be the same as given. From the choices, the answer is <span>{(-3, -3), (0, 0), (12, 12)}</span>
You run in a race at a rate of 4 miles per hour for 60 minutes and your friend runs in the race at a rate of 3.5 miles per hour for 60 minutes.
Your friend starts running 10 minutes before you, and you run for a half hour
Friend: 40/60 × 3.5 = 2 1/3 miles
You: 30/60 × 4 = 2 miles
You won't catch up in a half hour
4 mph: = 4×5280
_______ =352 ft/min; y = 352x
60
3.5 mph: = 3.5×5280
________ = 308 ft/min; y = 308(x+10)
60
( ____ this is a fraction bar. lol)
You take about 70 min for you to catch your friend
