Answer: What is the distance formula is that it's the formula used in Mathematics such as Pre-Algebra, Algebra 1, Geometry, Algebra 2, Trigonometry, and Pre-Calculus, also Calculus to help you find the distance between 2 points in a coordinate plane or the length of a segment. How you do the distance formula is you subtract the 2nd x coordinate by the 1st one, next you add the 2nd y coordinate to the 1st one, then the answer you get you evaluate them using the exponent of 2, lastly you add that answer and square root the answer you get to the approximate or closest decimal or whole number.

Answer:

8.85% per year

Step-by-step explanation:

To find the interest rate of a compounding interest, we use the formula:

$r=n[(\dfrac{A}{P})^{\dfrac{1}{nt}}-1]$

Before we start solving, let's break down all the variables that we have.

A = 19,992.71

P = 10,000.00

n = 2

t = 8

r = ?

Now let's put the values into the formula.

$r=2[(\dfrac{19,992.71}{10,000.00})^{\dfrac{1}{2(8)}}-1]$

$r=2[(\dfrac{19,992.71}{10,000.00})^{\dfrac{1}{16}}-1]$

$r=2[(\dfrac{19,992.71}{10,000.00})^{0.0625}-1]$

$r=2[(1.9992.1)^{0.0625}-1]$

$r=2[1.0442499885-1]$

$r=2[0.0442499885]$

$r=0.08849997699$ or $8.85%$

So the rate the Mrs. Emily Francis got from the bank was 8.85% per year.

A is in the shape of a quarter circle of a radius of 15cm. B is in the shape of a circle. the area of shape A is 9x the area of

RideAnS [48]

The radius of B is 2.5cm.

<h3>What is a circle?</h3>

A circle is the locus of points equidistant from a common point which is called the center of the circle.

Analysis:

Area of circle A = π $r^{2}$ /4 = π $(15)^{2}$ /4 = 225π/4

Area of circle B = π $r^{2}$

But A = 9B

225π/4 = 9 x π $r^{2}$

$r^{2}$ = 225/36 = 25/4

r = $\sqrt{\frac{25}{4} }$ = 5/2 = 2.5cm
