Which best represents the equation of this circle ?
likoan [24]

The equation of a circle:

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

(h, k) - center

r - radius

Look at the picture:

center: (4, -2) → h = 4, k = -2

radius: r= 5

Substitute:

(x-4)^2+(y-(-2))^2=5^2\\\\(x-4)^2+(y+2)^2=25\to\boxed{B.}

Mike and Ike are twins. Mike’s age is one more than twice a certain number. Ike’s age is 10 less than triple that same number. F
Misha Larkins [42]
Mike age is 3 less then twice the age of his brother nuke.
M = Mike's age now
N = Nuke's age now
M = 2N - 3

Ten years ago, four times nuke's age was one more mike's age.
M-10 = Mike's age 10 years ago
N-10 = Muke's age 10 years ago
4(N - 10) = 1 + M -10

what are their present ages

find M and N

substitute M = 2N - 3 into 4(N - 10) = 1 + M -10:

4(N - 10) = 1 + [2N - 3] - 10
4N - 40 = 2N - 12
2N = 28
N = 14

M = 2(14) - 3 = 28 - 3 = 25

Mike is 25 and Nuke is 14.

check:
4(14 - 10) = 4(4) = 16 = 26 -10 = 1 + 25 - 10

Insert three arithmetic means between 25 and 9​
Aleonysh [2.5K]

Answer:

21, 17, 13

Step-by-step explanation:

Find the mean of the 2 given values

mean = \frac{25+9}{2} = \frac{34}{2} = 17

Noe find the mean of 25 and 17 and 17 and 9

mean = \frac{25+17}{2} = \frac{42}{2} = 21 and

mean = \frac{17+9}{2} = \frac{26}{2} = 13

Thus the 3 means are 21, 17 and 13, that is

25, 21, 17, 13, 9
