Simple Interest Rate Formula: $\displaystyle A = P(1 + r)^t$

P is principle amount
r is rate
t is time (in years)

Step-by-step explanation:

Step 1: Define

Identify variables

P = 7300

r = 3% = 0.03

t = 10

Step 2: Solve for A

Substitute in variables [Simple Interest Rate Formula]: $\displaystyle A = 7300(1 + 0.03)^{10}$
(Parenthesis) Add: $\displaystyle A = 7300(1.03)^{10}$
Evaluate exponents: $\displaystyle A = 7300(1.34392)$
Multiply: $\displaystyle A = 9810.59$

HELP Give the slope ofleach line. Also, state if the lines are parallel (yes or no).

SpyIntel [72]

Answer:

The lines are parallel, and their slope is 1/3.

Step-by-step explanation:

Slope = Rise/Run

Rise tells us the distance between the two points on the y-axis and the run tells us the distance between the two points on the x-axis.

For Line 1, the rise is one unit and the run is three units. Therefore, the slope is 1/3.

For Line 2, the rise is one unit and the run is three units. Therefore, the slope is also 1/3.

Hope this helps!
