Answer: The kinetic energy of Derek's bike is 384.
To find the kinetic energy of an object, we need to know the mass and the velocity of the object. Both of those are already given in the problem. So we can simply use the formula.
The formula for kinetic energy is KE =0.5(m)v^2. All we need to do is input the know variables and evaluate.
KE = 0.5 (12) (8^2)
KE = 0.5(12)(64)
KE = 384
The answer is 16/10 = 40/25
You divided 16 by 40 to see what you need to multiply 16 to get 40. When I did that I got 2.5. So I did that to the 10 and got 25 minutes. Hope this makes sense
Answer:
106.21×4.77×103= <u>521820.351</u>
"3 less than twice 'x' " . . . . that's (2x - 3)
" 2 more than the quantity (3 x) " . . . . . that's (3x + 2)
Their product is
(2x - 3) (3x + 2) .
If you want to expand it to a single expression, perform the multiplication,
and you have
6x² - 5x - 6 .
