If 4 melons sell for $0.52, how much would 7 melons cost?

A company sells widgets. The amount of profit, y, made by the company, is related to

Y_Kistochka [10]

Answer:

774 dollars

Step-by-step explanation:

Given the amount of profit, y, made by the company, is related to

the selling price of each widget, x, by the given equation

y = -8x^2 + 242x – 1056

The company made her maximum profit when dy/dx = 0

dy/dx = -16x + 242

0 = -16x + 242

16x = 242

x = 242/16

x = 15.125

Get the maximum amount of the profit

Substituting x = 15.125 into the function we have:

y = -8(15.125)^2 + 242(15.125) – 1056

y = -8(228.77)+3,660.25-1056

y = -1,830.09+3,660.25-1056

y = 773.91

Hence the maximum amount of profit the company can make, to the nearest dollar is 774 dollars

What is the answer to a chef needs to cook 9 potatoes.He has already cooked 7.If each potato takes 3 minutes to cook,how long wi

jok3333 [9.3K]

Answer:it will it take him 6 minutes to cook the rest.

Step-by-step explanation:

The chef needs to cook a total of 9 potatoes. He has already cooked 7 potatoes. That means that the number of uncooked potatoes left is total number of potatoes - number of cooked potatoes. It becomes

9-7 = 2 potatoes

If each potato takes 3 minutes to cook, this means that 2 potatoes will take 3 minutes × 2 j = 6 minutes

Since there are only 2 potatoes left uncooked, it will it take him 6 minutes to cook the rest.

Solve 3x − 8 = 8 for x using the change of base formula log base b of y equals log y over log b.

Gelneren [198K]

Answer:

3^x-8=8 then x=log_3(16)

3^(x-8)=8 then log_3(8)+8

Step-by-step explanation:

So if it is 3^x-8=8

then 3^x=16

and then convert to logarithmic form you write it as log_3(16)=x

_3 means the subscript (the base) is 3

So if it is 3^(x-8)=8

then the log form is log_3(8)=x-8

add 8 on both sides log_3(8)+8=x
