Answer:

Step-by-step explanation:

The formula for energy us given as

E=½mv²

This change of formula question, we want to make v the subject of the formula

E=½mv²

Multiply the right and side and the left hand side by 2 to eliminate the ½

2×E= 2×½ mv²

Then, we have

2E=mv²

Divide both side of the equation by m to eliminate m

2E/m=mv²/m

So we have

2E/m=v²

Now take the square of both side of the equation to eliminate square of v

±√(2E/m)=√v²

±√(2E/m)=v

Then,

v=±√(2E/m)

The last option is the correct option

v = plus-or-minus StartRoot StartFraction 2 uppercase E Over m EndFraction EndRoot

What is the radius of a circle represented (y-5)^2+(x-14)^2=16
puteri [66]

Answer:

Explanation: The formula for the equation of a circle is shown below.

(x - h)² + (y - k)² = r²

In the equation, (h,k) is the center of the circle and <em>r</em> is the radius.

To find the radius, we look at the original formula and notice that the radius squared is equal to 16 or <em>r² = 16</em>.

Simply take the square root of both sides to get <em>r = 4</em>.

So this circle has a radius of 4.

A function f is odd and f(x)=x2 for all x&gt;0. Sketch the graph of this function and then write the rule of this function as a
brilliants [131]

For the function to be an odd function, then f(-x) = -f(x) and the function f(x) is not an odd function

<h3>How to determine the function?</h3>

The function f(x) is given as:

f(x) = x^2

For the function to be an odd function, then the following must be true:

f(-x) = -f(x)

So, we have:

f(-x) = (-x)^2 = x^2

-f(x) = -x^2

From the above computation, we can see that the functions f(-x) and -f(x) are not equal

Hence, the function f(x) is not an odd function

Suppose both factors in a multiplication problem are the multiples of 10. Explain why the number of zeros in the product may be
Ksenya-84 [330]

Answer:

Step-by-step explanation:

Take 20 and 50.

20 * 50 = 1000.

We have the 2 zeros in 20 and 50 , also 2 * 5 = 10, making 3 zeroes.
