O A. n1/r = a
✓ B. = a
c. a1/nur
O D. a' = n.

Answers

Answer 1

Answer:

B. a = rⁿ

C. a¹/ⁿ = r

Step-by-step explanation:

ⁿ√a = r

The above expression can be simplified as follow:

1. ⁿ√a = r

Recall:

ⁿ√a = a¹/ⁿ

Therefore,

a¹/ⁿ = r

2. ⁿ√a = r

Take the n square of both side

(ⁿ√a)ⁿ = rⁿ

(a¹/ⁿ)ⁿ = rⁿ

a = rⁿ

Write a system of equations to describe the situation below, solve using substitution, and fillin the blanks.Nora, an office manager, needs to find a courier to deliver a package. The first courier she isconsidering charges a fee of $14 plus $5 per kilogram. The second charges $15 plus $4 perkilogram. Nora determines that, given her package's weight, the two courier services areequivalent in terms of cost. What is the weight? How much will it cost?

Answers

The first courier service cost is;

$5x+14$

Where, x is the number of kilograms delivered;

The second courier service cost is;

$4x+15$

Equating it, we have;

$\begin{gathered} 5x+14=4x+15 \n x=1 \end{gathered}$

Thus, the weight that will result in equal cost is 1 kilogram.

And the cost is 5( 1 )+14 = $19
