Answer:
v = ± ![\sqrt{\frac{2E}{m} }](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7B2E%7D%7Bm%7D%20%7D)
Step-by-step explanation:
Given
E =
( multiply both sides by 2 to clear the fraction )
2E = mv² ( divide both sides by m )
= v² ( take the square root of both sides )
v = ± ![\sqrt{\frac{2E}{m} }](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7B2E%7D%7Bm%7D%20%7D)
Yes, it's in scientific notation.

Answer: 39
Step-by-step explanation: you have to plug in -4 into each x so that would be f(-4)=2(-4)(2)+7(-4)(3)-8(-4)(2)-21(-4)+7= 39
Answer:
B
Step-by-step explanation:
many different values of x lead to the same value of y.
hence, many-to-one.
but it does not mean that all values of x have to lead to the same value of y. it could be, but it is not demanded. so, it is not necessarily a horizontal line.
and this does not give us any information about the power of x involved. so, we cannot make any statement about linear or non-linear function.
