I NEED HELP WITH BOTH OF THESE

first one is C

the second it is A

Step-by-step explanation:

the equation of a circle=(x-h)^2 + (y-k)^2 = r^2

h and k are the coordinate of the origin of a circle

to find the origin  which is the midpoint of the diameter which has end points

(9,1) and (1,9)

h=9+1/2 = 10/2=5

k=9+1/2 = 10/2=5

(x-5)²+(x+5)²=r²

find r which is the half distance of the diameter

d of diameter : √(x2-x1)²+(y1-y2)²

d=√(9-1)²+(1-9)²

d=√8²+8²=8√2

radius=8√2/2=4√2

(x-5)²+(x+5)²=r²

(x-5)²+(x+5)²=(4√2)²

(x-5)²+(x+5)²=32

TR>TS the sides RS and TS are congruent opposite angles are equal.

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316

step-by-step explanation:

i found the life tables for the year 2012. 

life table of males at age 30. probability of dying between ages x and x+1

total population:  

29–30 . . . . . . . . . . . . 0.001030

30–31 . . . . . . . . . . . . 0.001061

males:  

29–30 . . . . . . . . . . . . 0.001420

30–31 . . . . . . . . . . . . 0.001448

white population

29–30 . . . . . . . . . . . . 0.001005

30–31 . . . . . . . . . . . . 0.001037

white males

29–30 . . . . . . . . . . . . 0.001372

30–31 . . . . . . . . . . . . 0.001399

non hispanic white population

29–30 . . . . . . . . . . . . 0.001083

30–31 . . . . . . . . . . . . 0.001116

non hispanic white males

29–30 . . . . . . . . . . . . 0.001477

30–31 . . . . . . . . . . . . 0.001503

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old. 

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

                                          probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497
