Step-by-step explanation:
of its previous height. What height
will it reach after the third bounce?
Answer:
1.7342 m
Step-by-step explanation:
in order to find this, we need to find what 2 thirds of 6 is. The answer to that is 4, because 2/3 can be changed to 4/6, which means the 1st bounce would reach a height of 4m. Now, we need to find 2 thirds of 4, which is mildly harder. In order to find the exact value, we need to find what to multiply 3 by to get to 4. Unfortunately, you cant do that. Fortunately, though, I looked it up. So, On the 2nd bounce, the ball would reach 2.6 m. Now, we need to find 2 thirds of THAT, too, which would equal, on the third bounce, 1.7342 m.
The height of the ball after the third bounce is approximately 1.78 m.
To find the height after the third bounce, we need to calculate the height after each bounce and then determine the height after the third bounce.
Given that the ball rises to 2/3 of its previous height after each bounce, we can start with the initial height of 6 m and calculate the height after the first bounce, which is 6 * 2/3 = 4 m.
Similarly, after the second bounce, the height will be 4 * 2/3 = 8/3 m. Finally, after the third bounce, the height will be (8/3) * (2/3) = 16/9 m, which is approximately 1.78 m. Therefore, after the third bounce, the ball will reach a height of approximately 1.78 m.

To find the value of k that satisfies the equation 7(7 - k) + 3k = -2(9k + 4) + 15, you can follow these steps:
1. Distribute the constants and variables on both sides of the equation:
7 * 7 - 7 * k + 3k = -2 * 9k - 2 * 4 + 15
2. Simplify both sides:
49 - 7k + 3k = -18k - 8 + 15
3. Combine like terms on each side:
(49 - 8) - 4k = -18k + 15
41 - 4k = -18k + 15
4. Move the variable terms to one side and the constant terms to the other side by adding 18k and subtracting 41 from both sides:
41 - 4k + 18k = 15
14k - 41 = 15
5. Add 41 to both sides to isolate the variable term:
14k = 15 + 41
14k = 56
6. Finally, divide by 14 to solve for k:
k = 56 / 14
k = 4
So, the value of k that satisfies the equation is k = 4.

list three errors the student made
Answer:
This is the right answer
Step-by-step explanation:
The student got the incorrect Midpoint because, they subtracted the x and y values rather than adding them. The correct Midpoint would be (6.5, 4.5).
