Answer 1

Answer:

Answer:

$\large\boxed{r^2=(x+5)^2+(y-4)^2}$

Step-by-step explanation:

The equation of a circle:

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

(h, k) - center

r - radius

We have diameter endpoints.

Half the length of the diameter is the length of the radius.

The center of the diameter is the center of the circle.

The formula of a distance between two points:

$d=√((x_2-x_1)^2+(y_2-y_1)^2)$

Substitute the coordinates of the given points (-8, 2) and (-2, 6):

$d=√((6-2)^2+(-2-(-8))^2)=√(4^2+6^2)=√(16+36)=√(52)$

The radius:

$r=(d)/(2)\to r=(√(52))/(2)$

The formula of a midpoint:

$\left((x_1+x_2)/(2),\ (y_1+y_2)/(2)\right)$

Substitute:

$x=(-8+(-2))/(2)=(-10)/(2)=-5\n\ny=(2+6)/(2)=(8)/(2)=4$

$(-5,\ 4)\to h=-5,\ k=4$

Finally:

$(x-(-5))^2+(y-4)^2=\left((√(52))/(2)\right)^2\n\n(x+5)^2+(y-4)^2=(52)/(4)\n\n(x+5)^2+(y-4)^2=13$

Carleen Bailey works at a boutique eight hours a day, earning $9.48 an hour. She is asked to work two additional hours at time and a half to help prepare for an incoming shipment. How much will she earn for these two hours of overtime?

Answers

Answer:

The correct answer is $23.70.

Step-by-step explanation:

9.48 times 2.5 is 23.7

Final answer:

Carleen Bailey would earn $28.44 for the two hours of overtime she worked. She earns 1.5 times her normal hourly wage for overtime hours.

Explanation:

Carleen Bailey earns $9.48 for each regular hour she works. When she works overtime, she earns 1.5 times her normal rate for each additional hour. That means her overtime rate is $9.48 * 1.5 = $14.22 per hour. Therefore, if she works 2 hours of overtime, she will earn $14.22 * 2 = $28.44 in total for the overtime hours.
