A batter hits a pitched ball when the center of the ball is 1.22 m above the ground. The ball leaves the bat at an angle of $$\displaystyle{45}^{{\circ}}$$ with the ground. With that launch, the ball should have a horizontal range (returning to the launch level) of 107 m. a) Does the ball clear a 7.32-m-high fence that is 97.5 m horizontally from the launch point? b) At the fence, what is the distance between the fence top and the ball center? waigaK 2021-10-08 Answered

Determine whether the data from the table could represent a function that is linear, exponential, or logarithmic. $$\begin{array}{|c|c|c|c|c|c|c|c|c|} \hline x & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 & 10 \\ \hline f(x) & 2 & 4.079 & 5.296 & 6.159 & 6.828 & 7.375 & 7.838 & 8.238 & 8.592 & 8.908 \\ \hline \end{array}$$ Tolnaio 2021-10-07 Answered

If John, Trey, and Miles want to know how’ | many two-letter secret codes there are that don't have a repeated letter. For example, they want to : count BA and AB, but they don't want to count“ doubles such as ZZ or XX. Jobn says there are 26 + 25 because you don’t want to use the same letter twice. that’s why the second number is 25. ‘Trey says he thinks it should be times, not plus: 26-25, Miles says the number is 26-26 ~ 26 because you need to take away the double letters. Discuss the boys’ ideas, Which answers are correct, which are not, and why? Explain your answers clearly and thoroughly, drawing ‘on this section’s definition of multiptication.. - Suman Cole 2021-09-30 Answered
