Answer:
See below.
Step-by-step explanation:
This is the formula for the value of an investment with compound interest.
PO is the initial amount invested, P is the amount after investing t years , r is yearly rate of interest (as a fraction) and n is the number of times interest is paid per year.
An example using values will serve to explain it further. If the rate is 2% ( which = 0.02) per year and the interest is added to the account every 6 months ( twice a year) then, in the parentheses we have ( 1 + 0.02/2). The 1 is there because we are talking about the amount of money PLUS the interest. Now if we are dealing with 5 year's investment , the exponent nt will be 2*5 = 10 because the interest is paid 2 times a year over 5 years: - 10 payments. So if we invest 10,000 at 2% interest over 5 years with 2 interest payments a year the total after 5 years = P = 10,000(1 + 0.02/2)^10 = 11,046.22.
Answer written clearly above! Function notation is simply switching y to f(x).
Answer:
<em><u>B is the answer.</u></em>
Step-by-step explanation:
Steps are in the picture.
-10+8x<6x-4 add 10 to both sides
8x<6x+6 subtract 6x from both sides
2x<6 divide both sides by 2
x<3
Answer:
36 gallons
Step-by-step explanation:
y = 4/5x
Let x = 45 minutes
y = 4/5 (45)
y = 36 gallons
