A family is comparing different car seats. One car seat is designed for a child up to and including 36 lb. Another car seat is designed for a child between 19 lb and 35 lb. A third car seat is designed for a child between 36 lb and 80 ​lb, inclusive. Model those ranges with compound inequalities. Which car seats are appropriate for a 32​-lb ​child?

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

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

: )

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
