Answer:

The correct answer is D.

Step-by-step explanation:

The given expression for the substance in shipment 2 is

$f(t)=50(\frac{1}{2})^{\frac{t-2}{5}}$

$f(t)=50(\frac{1}{2})^{(\frac{t}{5}-\frac{2}{5})}$

We use the law of exponents to determine an equivalent expression.

Recall that,

$a^{m-n}=\frac{a^m} {a^n}$

We apply this property to obtain,

$f(t)=\frac{50(\frac{1}{2})^{\frac{t}{5}}}{(\frac{1}{2})^{\frac{2}{5}}}$

The correct answer is D

Answer:

Step-by-step explanation:

The other responder works better with Latex than I do. I would have been too late anyway.

f(t) = 50*(1/2)^(t - 2)/5

f(t) = 50*(1/2)^(t/5) * (1/2)^(-2/5)

f(t) = 50* (1/2)^t/5 / (1/2)^(2/5)

f(t) = 50* $\dfrac{\sqrt[5]{(\frac{1}{2})^t}}{(\dfrac{1}{2})^\frac{2}{5} }$

Gina sells 216 cakes in the ratio small :medium:large 5:7:12. The profit for one medium cake is twice the profit for one small c

Rus_ich [418]

To answer this question you need to first set up the small, medium, large number of cakes as a ratio with a total. From here you will create a new ratio of the correct number of small medium and large Cakes sold using the total 216. The factor would be to multiply by nine. -Step 1 in picture. After this you would read what the relationship is between a medium and a small and the large and the small profits are - Step 2 in picture. After this you would represents the total profit based on the number of small medium and large cakes that were sold. Making this equal to L648.45. To find the profit for one small, you would then divide 648.45 by the 495 you got when you simplify the expression. The answer is L1.31.
