Answer:
B.254.34 in.2
Step-by-step explanation:
<em>x = 41 cm</em>
<u><em>Here is why:</em></u>
For this question we have to use the pythagorean theorem, which is used for right triangles. The hypotenuse will always be the last in this theorem.
Plug in.
Add together.
Now we will find the square root of 1,681, since <em>c </em>is squared.
= 41 cm
Answer: 3/28 of the book.
Step-by-step explanation: you simply take the said fraction that they give you, and divide the whole thing by 8. An 8th of 6/7 is 3/28!
To solve the problem shown in the figure attached in the exercise, you must follow the proccedure shown below:
1. You have that the<span> formula for calculate the velocity (v) in feet per second (ft/s), of an object that has fallen h feet is:
v=</span>√(64h)
<span>
2. The problem shown above asks for the velocity of an object that has fallen 23 feet. Therefore, to solve this exercise you only have to susbtitute h=23 feet into the formula for calculate the velocity (v), as below:
v=</span>√(64h)
h=23 feet
v=√(64)(23)
v=√(1472)
v=8√23
v=38.37 feet per second
3. Therefore, as you can see, the correct answer is the second option, which is: 38.37 feet per second
