Answer:
25-7
Step-by-step explanation:
"Substitute for": Replace x with ____
Since it is given that x = 25 -y, we can replace the x in 5x + y = 10 with 25 - y by the substitution property of equality.
Answer:
g(x) = -6 - 3x
f(x) = X^6
Step-by-step explanation:
Answer:
The difference is that the height of the cone is divided by 3
Step-by-step explanation:
formular of cylinder
![V=\pi r^2h](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%5E2h)
Formular of a cone
![V=\pi r^2\frac{h}{3}](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%5E2%5Cfrac%7Bh%7D%7B3%7D)
After every drop,the ball bounces to half it's previous height. With that understood.
1st drop -The ball drops 10m
1st bounce - 5m up
2nd drop - 5m down
2nd bounce - 2.5m up
3rd drop - 2.5m down
3rd bounce - 1.25m up
4th drop - 1.25m down
4th bounce - 0.625m up
5th/last drop - 0.625m down
To find the total vertical distance, you add them all.
10+5+5+2.5+2.5+1.25+1.25+0.625+0.625
=29.25m travelled in all.
