Option A

The simple interest earned over 6 years is $ 4050

<em><u>Solution:</u></em>

Martha invested a principal amount of $15,000 into a savings account that earns simple interest at a rate of 4.5% per year

<em><u>The formula for simple interest is given as:</u></em>

Simple\ Interest = \frac{p \times n \times r}{100}

Where, "p" is the principal and "n" is the number of years and "r" is the rate of interest

From given,

p = 15000

r = 4.5 %

n = 6 years

<em><u>Substituting the values we get,</u></em>

Simple\ Interest = \frac{15000 \times 4.5 \times 6}{100}\\\\Simple\ Interest = 150 \times 4.5 \times 6\\\\Simple\ Interest = 4050

Thus simple interest earned over 6 years is $ 4050

What are the values of sin α and tan α, if:<br> cosα=0.6
olganol [36]

Positive cosine is first or fourth quadrant.  So we don't know the sign of the sine or the tangent.

Everybody's favorite right triangle is 3/4/5 and here we have

\left(\dfrac 3 5 \right)^2 + \left(\dfrac 4 5 \right)^2 = 1

So if

\cos \alpha = 0.6 = \dfrac 3 5

then

\sin \alpha = \pm \dfrac{4}{5} = \pm 0.8

and

\tan \alpha = \dfrac{\sin \alpha}{\cos \alpha} = \dfrac{\pm 0.8}{0.6}=\pm \dfrac 4 3

After a bride has interviewed 7 DJs to play at her wedding, her fiance tells her she needs to narrow it down to 4 DJs. In how ma
Alex17521 [72]

Answer:

840

Step-by-step explanation:

Given

DJs = 7

To\ pick = 4

Required

Determine the number of rankings

The term "ranking" as used in this question implies permutation and the required is calculated using:

^nP_r = \frac{n!}{(n-r)!}

Where

n = 7

r = 4

So:

^nP_r = \frac{n!}{(n-r)!}

^7P_4 = \frac{7!}{(7-4)!}

^7P_4 = \frac{7!}{3!}

^7P_4 = \frac{7 * 6 * 5 * 4 * 3!}{3!}

^7P_4 = 7 * 6 * 5 * 4

^7P_4 = 840

<em>Hence, number of ranking is 840</em>
