Hi,

By definition, interest rate is the proportion of a loan that is charged as interest to the borrower, typically expressed as an annual percentage of the loan outstanding.

To find interest rate you need the principle, interest earned, and time.

Solve for Rate (R)

Where: r = I / Pt

I = 837 (dollars)

P = 3100 (dollars)

t = 6 (years)

r = 837 / ( 3100 × 6 ) = 0.045

r = 0.045

*converting r decimal to a percentage
R = 0.045 * 100 = 4.5%/year*

The interest rate required to accumulate simple interest of $ 837.00 from a principal of $ 3,100.00 over 6 years is 4.5% per year.

In short, rate: 4.5% / year

Let , −5−6 be a point on the terminal side of θ . find the exact values of cosθ , cscθ , and tanθ .

gizmo_the_mogwai [7]

Given that point (-5, -6) is a point on the terminal side of θ. Since both the x coordinate and the y-coordinate are negative, θ is in the third quadrant.

The side opposite θ is -6 and the side adjacent θ is -5.

The hypothenus is given by $\sqrt{(-6)^+(-5)^2}=\sqrt{36+25}=\sqrt{61}$

The exact value of cosθ is given by:

$\cos\theta= \frac{adjacent}{hypothenuse} = \frac{-5}{\sqrt{61}}$

The exact value of cscθ is given by:

$\csc\theta= \frac{hypothenuse}{opposite} = \frac{\sqrt{61}}{-6}$ 

The exact value of tanθ is given by:

$\tan\theta= \frac{opposite}{adjacent} = \frac{-6}{-5} =1.2$
