Answer:
2.070552361 miles
Step-by-step explanation:
2 / cos 15 = 2.070552361
The potential energy is converted into kinetic energy.
Therefore, for conservation of energy we have:
mgh = (1/2) m * v ^ 2
From here we clear the speed:
v = root (2 * g * h)
The height will then be:
h = v ^ 2 / (2 * g)
Substituting the values:
h = (34) ^ 2 / (2 * (32))
h = 18.0625 feet
Answer: The pear before it fell was 18.0625 feet up in the tree.
Answer:
8x^2 + 6x + 36xy^2 + 24y^2
Step-by-step explanation:
First, multiply the two terms inside the second set of parentheses by-2x; we get 8x^2 + 6x.
Next, multiply the same two terms by -9y^2; we get 36xy^2 + 24y^2.
Now add these products together:
8x^2 + 6x + 36xy^2 + 24y^2 This is the desired product.
First, I like switching the sides so that the equation looks like this: bv/k=M
Then get bv alone by multiplying both sides by k: bv=kM
After that, divide both sides by b to get v by itself: <u>v=kM/b</u>
