A diameter of a circle has endpoints P(-10,-2) and Q(4,6).

kompoz [17]

Answer:

a. (-3, 2).

b. √65

c. (x + 3)^2 + (y - 2)^2 = 65

Step-by-step explanation:

a. The center is the midpoint of the diameter PQ.

= (-10+4)/2, (-2+6)/2

= (-3, 2).

b. The radius is the distance from the center to a point on the circle.

Take the point (4, 6):

The radius = √((-3-4)^2 + (2-6)^2)

= √65.

c. The equation of the circle is:

Using the standard form

(x - h)^2 + (y - k)^2 = r^2 where (h, k) is the center and r = the radius:

it is (x - (-3)^2 + (y - 2) = 65

= (x + 3)^2 + (y - 2)^2 = 65.

Sara Blake's grandmother gave her $3000.00 to save for college. She put it in a savings account that earns 6% interest per year.

Elina [12.6K]

• P is the principal amount, $3000.00.

• r is the interest rate, 6% per year, or in decimal form, 6/100=0.06.

• t is the time involved, 8 years time periods.

• So, t is 8 year time periods.

To find the simple interest, we multiply 3000 × 0.06 × 8 to get that:

The interest is: $1440.00

There are 45 students who play a woodwind instrument in the school band. Of these, 18 play the saxophone. What percent of these

Mashutka [201]

Answer:

40% students play the saxophone.

Step-by-step explanation:

Given:

Total Number of students who play woodwind instrument = 45

Number of students who play saxophone = 18

We need to find the percent of students who play saxophone.

Solution:

Now we can say that;

To find the percent of students who play saxophone we will divide Number of students who play saxophone by Total Number of students who play woodwind instrument and the multiply by 100.

framing in equation form we get;

percent of students who play saxophone = $\frac{18}{45}\times100= 40\%$

Hence 40% students play the saxophone.
