Answer:
radius ≈ 15.5
Step-by-step explanation:
the radius is RS
the angle between a tangent and the radius at the point of contact is 90°
then Δ RST is a right triangle
using Pythagoras' identity in the right triangle.
the square on the hypotenuse is equal to the sum of the squares on the other 2 sides , then
RS² + ST² = RT² ( substitute values )
RS² + 7² = 17²
RS² + 49 = 289 ( subtract 49 from both sides )
RS² = 240 ( take square root of both sides )
RS = 
≈ 15.5 ( to 1 dec. place )
Answer:

Step-by-step explanation:
Answer:
Each boy recieved $25.25 each
Step-by-step explanation:
First, you add up all the money the 3 boys spent.
15+15+15=45
Then you add the sum of the equation to the amount all the boys had afterward.
45+30.75=75.75
Finally, you divide that product to 3 boys.
75.75/3=25.25
Therfore the answer is $25.25 each.
Answer:
its c. x = -2.5 and x = -2
Step-by-step explanation:
multiply function (g)(x) = (-2x-5)(x-2)
= -2x^2+4x-5x+10
first get out -2x(x+2)-5(x+2)
(-2x-5) or (x+2) = 0
x=-5/2 or x=-2
its c that both points covered in that line of x axis
Y= 1/2x -2 is the equation for this line.
