Glencoe geometry unit 9: whoever can answer the page gets 100 points and brainliest

Step-by-step explanation:

14. K' = x + a, y + b

= -1 + 2, 6 + 3

K' = 1, 9

K" = (x, y) → (-x, y)

= (1, 9) → (-1, 9)

K" = -1, 9

15. D. Octagon

Since it has 8 angles, of 360 ° is divided by 8 angles, then each corner has an angle of 45 °

16. P' = x + a, y + b

= -2 + 6, 4 + 5

P' = 4, 9

17. H' = x + a, y + b

= 5 + 10, 4 + (-11)

= 15, -7

18. A (6, -1)

A' = (x, y) → (x, -y)

= (6, -1) → (6, -(-1)

= 6, 1

19. J' = x + a, y + b

= -2 + (-3), 1 + (-3)

= -5, -2

J" = (x, y) → (x, -y)

= (-5, -2) → (-5, -(2))

= -5, -2

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius

: )

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
