Answer:

The answer would be f(x)={4x/9}

Step-by-step explanation:

f(x)=4({1}{3})^{2x}

Apply exponent rule:

f(x)=4({1^2}{3^2})^x

f(x)=4({1}{9})^x

the required function is f(x)=4({1}{9})^x

OR

If the function is f(x)=4(\frac{1}{3})^2x

Apply exponent rule:

f(x)=4({1^2}{3^2})x

f(x)=4({1}{9})x

f(x)={4x}{9}

Hence, the required function is f(x)={4x}{9}

I hope this helped. I am sorry if you get this wrong.

how many pounds of candy worth $12 per pound should be mixed with candy costing $19 per pound to produce a 70 pound mixture that
sweet-ann [11.9K]

Answer:

40 pounds

Step-by-step explanation:

Given: Cost of a candy (c_1)= \$ 12 per pound

           Cost of candy (c_2) = \$ 19\ per\ pound

           Total amount of mixture of be produced = 70\ pound

           Selling price of mixture = \$ 15 \ per\ pound

Let´s x be the amount of c_1 to be mixed in the mixture.

∴ Cost of c_1 in the mixture = 12x

Next, Cost of c_2 in the mixture = (70 - x)\times 19

And we know the cost of final mixture = 70 \times 15 = 1050

Now, putting all the value in the equation

⇒ 12x + 19 \times (70 - x) = 1050

⇒ 1330 - 7x = 1050

⇒ -7x = -280

∴ x = 40\ pound

∴ 40 pounds of candy worth $12 per pound to be mixed in the mixture.
