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} }

Can you solve this equation???
ad-work [718]

Answer:

-6

Step-by-step explanation:

Move the variable to the left hand side and change its sign.

5 - 2x + 4x = -7

Collect like terms.

- 2x + 4x = - 7 - 5

2x = - 7 - 5

Calculate the difference.

2x = -12

Divide both sides.

x = -6

Robert is a salesperson. He receives 7% commission on each piece of electronic equipment he sells. How much commission will he r
Shalnov [3]

Answer:

He receives $476 in comission.

Step-by-step explanation:

This question can be solved using a rule of three.

$6,800 is 100% = 1. x, which is his commision, is 7% = 0.07. Then

6800 - 1

x - 0.07

x = 6800*0.07

x = 476

He receives $476 in comission.

Solve the following system of equations for a and for b:
viktelen [127]

Answer:

a=3\\b=1

Step-by-step explanation:

9a+3b=30\\8a+4b=28

Let's solve the second equation for a to later on replace it in the first equation.

8a+4b=28\\8a=28-4b\\a=\frac{28-4b}{8}

Now plug this into the first equation.

9a+3b=30\\9(\frac{28-4b}{8})+3b=30

Distribute the 9

(\frac{252-36b}{8}) +3b=30

Break down the fraction.

\frac{252}{8}-\frac{36b}{8}+3b=30

Simplify.

\frac{63}{2}-\frac{9}{2}b+3b=30

Subtract \frac{63}{2}

-\frac{9}{2}b+3b=30-\frac{63}{2}

Combine like terms.

\frac{-9+2*3}{2}b=\frac{30*2-63}{2}

\frac{-9+6}{2}b=\frac{60-63}{2}

\frac{-3}{2}b=\frac{-3}{2}

Muliply by the reciprocal or inverted fraction next to b.

(-\frac{2}{3})(-\frac{3}{2}) b=-\frac{3}{2}(-\frac{2}{3})

b=1

Now plug this value into any of the equations to find the value of a.

8a+4b=28\\8a+4(1)=28\\8a+4=28\\8a=28-4\\8a=24\\a=\frac{24}{8}\\ a=3
