At first rebound;

Second rebound

Third rebound

Hence; the equation is:

Solving further;

Answer:
B
Step-by-step explanation:
3 x -9 which is -27. Then you have to add the exponents, so it will be x^4+2 = x^6 , y^3+2 = y^5, z^1+2 = z^3. so your answer will be -27 x^6 y^5 z^3
Answer:
√50
Step-by-step explanation:
Use Pythagorean Theorem: a^2+b^2=c^2
5^2+5^2=c^2
25+25=c^2
50=c^2
c=√50
Answer:
<CDG and <CDB are supplementary angles.
Answer:
Step-by-step explanation:
k = xy
Putting values of x and y in the equation
k = (5)(-3.5)
= - 17.5
Finding value of x when y = 10
k = xy
- 17.5 = x10
Bringing like terms on one side
- 17.5 - 10 = x
-27.5 = x
