Answer:
A
Step-by-step explanation:
The projectile motion of Jenny's dive can be represented by where a is acceleration, v_0 is velocity, t is time, and h_0 is initial height.
Jenny's vertical height above the water is represented by . 10 is h_0 and is Jenny's initial height.
Answer:
Step-by-step explanation:
This is a 45°-45°-90° triangle. The two legs are the same length, and the hypotenuse is that length times the square root of two:
Therefore, the value of x is 11.
You can double-check using the sine ratio:
Insert the values:
Insert the equation into a calculator:
:Done
*It's important to know that, when working with trigonometry ratios, the hypotenuse is never considered the adjacent or opposite side, and the 90° angle is never used in the ratios.
