You have just taken out a $2,650 loan from your local bank. You paid off the loan in 1 year by making 12 monthly payments with a
Nastasia [14]

Answer:

20.33%

Step-by-step explanation:

Principal = $2650

Total Interest = $300

Total amount = 42650+$300=$2950

Since we are given that You paid off the loan in 1 year by making 12 monthly payments

So, monthly payment = \frac{2950}{12} =245.833

Formula of monthly payment = \text{Monthly payment }= \frac{Principal \times \frac{i}{12}}{1-(1+\frac{i}{12})^{-12}}

where i is the rate of interest in decimals

To find i substitute the values

245.833= \frac{2650 \times \frac{i}{12}}{1-(1+\frac{i}{12})^{-12}}

using calculator

i=0.2033

So, rate of interest in percent = 0.2033 \times 100 = 20.33\%

Thus the annual percentage rate (APR) is 20.33%

A analog clock (with hour and minute hands) is set to 5:00 P.M. After 30 min, what will the measure of the major arc formed by h
VikaD [51]

Answer:

180 degrees

Step-by-step explanation:

Given

Time = 5:00pm

Required

The measure of the major arc, 30 minutes after

First, we calculate the time after 30 minutes

Time = 5:00pm +30\ mins

Time = 5:30pm

At 5:30pm, the hour and the minute hand will be directly opposite each other.

In other words, the hands divide the time into two equal parts (180 degrees each)

At this point, there is no major or minor arc as both sides have the same measurement

<em>Hence, the measure of the arcs is 180 degrees</em>

Hello, precalc, need help on finding csc
Ainat [17]

Recall the double angle identity for cosine:

\cos(2x) = \cos^2(x) - \sin^2(x) = 1 - 2 \sin^2(x)

It follows that

\sin^2(x) = \dfrac{1 - \cos(2x)}2 \implies \sin(x) = \pm \sqrt{\dfrac{1-\cos(2x)}2} \implies \csc(x) = \pm \sqrt{\dfrac2{1-\cos(2x)}}

Since 0° < 22° < 90°, we know that sin(22°) must be positive, so csc(22°) is also positive. Let x = 22°; then the closest answer would be C,

\csc(22^\circ) = \sqrt{\dfrac2{1-\cos(44^\circ)}} = \sqrt{\dfrac2{1-\frac5{13}}} = \dfrac{\sqrt{13}}2

but the problem is that none of these claims are true; cot(32°) ≠ 4/3, cos(44°) ≠ 5/13, and csc(22°) ≠ √13/2...
