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.
Answer:
33 and 13
Step-by-step explanation:
46/2 = 23
difference is 20, add 10 to one and subtract 10 from 23, giving you two numbers: 13 and 33.
To multiply decimals: Set up and multiply the numbers as you do with whole numbers. Count the total number of decimal places in both of the factors. Place the decimal point in the product so that the number of decimal places in the product is the sum of the decimal places in the factors.
Answer:
36
Step-by-step explanation:
area of a rectangle is length x width, so 12 x 3 = 36
In 10 seconds, in fills = 2 L
so, in 1 sec, it will fill = 2/10 L = 1/5 L = 0.2 L or 200 mL
In short, Your Answer would be 0.2 Liter or 200 milliliter
Hope this helps!
