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} }

The sum of two trinomials is 7x2 - 5x + 4. if one of the trinomials is 3x2 + 2x - 1, then what is the other trinomial?
Margarita [4]

Answer:

  b.  4x^2 -7x +5

Step-by-step explanation:

When you know a sum and one of its contributors, you can find the other by subtraction. The other trinomial is ...

  (7x^2 -5x +4) - (3x^2 +2x -1)

  = (7 -3)x^2 +(-5 -2)x +(4 -(-1))

  = 4x^2 -7x +5 . . . . . matches B

inessss [21]
Most of the information's required for finding the answer is already given in the question. 
Height of the fly = 12 feet
Width of the fly = 16 feet
Now we can find the length of the poles using Pythagoras theorem.

Length of the poles = square root [(12)^2 + (8)^2]
                               = square root (144 + 64)
                               = square root (208)
                               = 14.4 feet
From the above deduction, we can conclude that the height of the poles needed to be 14.4 feet. I hope the answer has helped you.
