Answer:

2(s-c)/ a^2 =  v

Step-by-step explanation:

s = 1/2 a^2 v+c

Subtract c from each side

s -c = 1/2 a^2 v+c-c

s-c = 1/2 a^2 v

Multiply each side by 2

2(s-c) = 2* 1/2 a^2 v

2(s-c) = a^2 v

Divide each side by a^2

2(s-c)/ a^2 = a^2 v /a^2

2(s-c)/ a^2 =  v

​Cameron, Arthur, and Jamie are playing soccer. Their locations are recorded by a motion tracking system. The grid shows distanc
Luden [163]

Answer:

1. Arthur is about 54 meters away from Cameron.

2. Jamie is about 56 meters away from Cameron.

3. Arthur is closer to Cameron.

Step-by-step explanation:

We have been given the locations of Cameron (70,10), Arthur (20,30) and Jamie (45,60) on the the grid in meters.

1. To find the distances of Arthur and Jamie from Cameron we will use distance formula.

\text{Distance}=\sqrt{(x_2-x_1)^{2}+(y_2-y_1)^{2}}

\text{Distance between Cameron and Arthur}=\sqrt{(70-20)^{2}+(10-30)^{2}}

\text{Distance between Cameron and Arthur}=\sqrt{(50)^{2}+(-20)^{2}}

\text{Distance between Cameron and Arthur}=\sqrt{2500+400}

\text{Distance between Cameron and Arthur}=\sqrt{2900}

\text{Distance between Cameron and Arthur}=53.8516480713450403\approx 54

Therefore, the distance Arthur is about 54 meters away from​ Cameron.

2. Let us find the distance between Cameron and Jamie.

\text{Distance between Cameron and Jamie}=\sqrt{(70-45)^{2}+(10-60)^{2}}

\text{Distance between Cameron and Jamie}=\sqrt{(25)^{2}+(-50)^{2}}

\text{Distance between Cameron and Jamie}=\sqrt{625+2500}

\text{Distance between Cameron and Jamie}=\sqrt{3125}

\text{Distance between Cameron and Jamie}=55.9016994374947424\approx 56

Therefore, Jamie is about 56 meters away from​ Cameron.

3. We can see that 56 is greater than 54, therefore, Arthur is closer to Cameron.

What is the value of the expression All of 3.9 multiplied by 10 to the power 5 over all of 1.3 multiplied by 10 to the power 2?
Dima020 [189]
So first write out the expression:
\frac{3.9*10^{5}}{1.3*10^{2}}
take two 10's from the top to cancel with the two 10's on the bottom.
3.9/1.3 is 3.
The answer is 3*10^3

Pls help meh<br><br> 6th grade math
defon

Answer:

100%

Step-by-step explanation:

It says 38 out of 38 votes were for hunger relief. If it were like that, it would be 100%. Same as if it were 22 out of 22 votes. Like, think about if you were taking a test with 20 questions, and you got 20 questions right. You'd get a hundred percent, right? Same thing here, just a different equation.

Hope this helps
