The cost for 9 lbs would be 63 dollars
Answer:
Step-by-step explanation:
Pay attention to the procedure:
(5(10)^2)^3/(10(5))^4. What we need is plug in the corresponding x and y values Then you have to do x squared before you multiply it by 5 like this: (5(100))^3/(10(5))^4 Now solve for what is in the top parenthesis. (500)^3/(10(5))^4 500^3=125000000 Now work on the denominator. Do what is inside the parenthesis first 10*5=50 Now (50)^4=6250000 Now divide the numerator and the denominator. 125000000/6250000 Which equals 20, Please check if I'm wrong but I think this is what you need
2.74x7.5=20.55=20.550
That's all of your answers.
I will assume that 0.62 is an exponent then
amount left after t seconds = f(6) = 5 - 0.82(6)^0.62
= 2.51 gallons to nearest hundredth.
