Answer:

$(x-1)^2+(y+4)^2=9$

Step-by-step explanation:

The equation of a circle is given by:

$(x-h)^2+(y-k)^2=r^2$

Where (h, k) is the center and r is the radius.

The center of the circle is (1, -4).

And the radius is 3.

Substitute:

$(x-(1))^2+(y-(-4))^2=(3)^2$

Simplify. Thus, our equation is:

$(x-1)^2+(y+4)^2=9$

A man borrowed $8000. He paid $10100 after 9 months for the debt. What was the interest rate per annum?

Anastaziya [24]

2100 = 600r

2100/600 = r

Jacob and issac decided to run to the basketball court after school the basketball court is 5 1/4 Miles from school the boys run

GenaCL600 [577]

Answer: $1\dfrac{5}{9}\text{ minutes}$

Step-by-step explanation:

Complete question is provided in the attachment below.

Given: Jacob and Issac decided to run to the basketball court

Distance between basketball court and school = $5\dfrac{1}{4}$ miles

$=\dfrac{21}{4}$ miles

Speed = $3\dfrac{3}{8}$ miles per hour

$=\dfrac{27}{8}$ miles per hour

Since, time = (distance) ÷ ( speed)

Now, the time taken by boys to arrive at the basketball court = $\dfrac{21}{4}\div\dfrac{27}{8}$ hours

$=\dfrac{21}{4}\times\dfrac{8}{27}\\\\=\dfrac{7\times2}{9}=\dfrac{14}{9}\\\\=1\dfrac{5}{9}\text{ minutes}$

Hence, the required length of time = $1\dfrac{5}{9}\text{ minutes}$
