What is the equation of the circle with a diameter of 6 units and a center located at (2, −5) on the coordinate plane? a A b B c

Nastasia [14]

Answer:

$(x-2)^2+(y+5)^2=36$

Step-by-step explanation:

Recall that the equation of a circle of radius R centered at $(x_0,y_0)$ is given by:

$(x-x_0)^2+(y-y_0)^2=R^2$

For your particular case: R = 6, $x_0$ = 2, and $y_0$ = -5, therefore the equation becomes:

$(x-x_0)^2+(y-y_0)^2=R^2\\(x-2)^2+(y-(-5))^2=6^2\\(x-2)^2+(y+5)^2=36$

What is this equation in point-slope form?

deff fn [24]

Answer:

y - 2 = $\frac{1}{2}$ (x + 8)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = $\frac{1}{2}$ and (a, b) = (- 8, 2), hence

y - 2 = $\frac{1}{2}$ (x + 8) ← in point- slope form

The formula for the future value V (in dollars) of an investment earning simple interest is V=p+prt, where p (in dollars) is the

serious [3.7K]

Answer:

A. $p=\dfrac{V}{1+rt}$

B. $2,307.69

Step-by-step explanation:

You are given the formula

$V=p+prt,$

where V = investment earning simple interest

p = principal,

r = interest rate

t = time

So,

A. $V=p(1+rt)\\ \\p=\dfrac{V}{1+rt}$

B. r = 0.06 (or 6% as percent)

V = $3,000

t =5

so,

$3,000=p+p\cdot 0.06\cdot 5\\ \\3,000=p+0.3p\\ \\1.3p=3,000\\ \\p=\dfrac{3,000}{1.3}\approx 2,307.69$
