If John deposits $525 in a savings account and his account pays an annual interest rate of 5.5% and makes no other deposits and

Marianna [84]

Answer:

The amount of simple interest earned is $156.79

Step-by-step explanation:

Mathematically;

Simple interest = PRT/100

From the question;

P = $525

R = 5.5%

T ; to get this, we need to make the numbers agree;

We do this by dividing number of months by 12 and number of days by 365

So 5 years, 5 months and 5 days will be;

5 + 5/12 + 5/365 = 5.43

So, using this in the simple interest calculations, we have;

S.I = (525 * 5.5 * 5.43)/100

S.I = $156.79

Find the x intercepts of y=2x^2+x-21

Anton [14]

The x intercept is when y=0. Substitute:

$2x^2+x-21=0$

Solve for x by factoring.

$2x^2-6x+7x-21=0$

$=2x(x-3)+7(x-3)=0$

$=(x-3)(2x+7)=0$

$x=3$ AND $x=-\frac{7}{2}$

So therefore, we have our intercepts:

(3,0) & (-7/2,0)
