Answer:

v=√(2KE/m)

Step-by-step explanation:

KE=1/2mv^2

2KE=mv^2

(2KE)/m=v^2

sqrt[(2KE)/m]=v

v=√(2KE/m)

Answer:

v=\sqrt{\frac{2KE}{m} }

Step-by-step explanation:

KE = 1/2mv^2

KE/1/2=mv^2

2KE=mv^2

2KE/m=v^2

\sqrt{2KE/m} =v

Cant solve this please help me <br><br> 9x-2y=8 <br> Y=2x+1
ki77a [65]
Substitute 2x+1 where y is in the equation:

9x-2(2x+1)=8

Then distribute the -2(2x+1)

9x-4x+2=8

Then combine like terms (the x)

5x+2=8

Then do -2 on both side of the equation sign

5x+2=8
- 2 -2

Then you'd get

5x=6

Then divide 5 on both sides

X= 1.2

Write the next three terms of the arithmetic sequence.
JulijaS [17]

The next three terms are: 1/6 , 0 and -1/6

Step-by-step explanation:

Given sequence is:

\frac{5}{6} , \frac{2}{3} ,\frac{1}{2}, \frac{1}{3} ...

First of all, we have to find the common difference

here\\a_1 = \frac{5}{6}\\a_2 = \frac{2}{3}\\a_3 = \frac{1}{2}\\a_4 = \frac{1}{3}\\d = a_2-a_1 = \frac{2}{3} -\frac{5}{6} = \frac{4-5}{6} = -\frac{1}{6}\\d = a_3 - a_2 = \frac{1}{2} - \frac{2}{3} = \frac{3-4}{6} = =\frac{1}{6}

The common difference is -1/6

We can simply add -1/6 to the previous term to find the next terms so,

Adding -1/6 to 1/3

\frac{1}{3} - \frac{1}{6} = \frac{2-1}{6} = \frac{1}{6}\\\frac{1}{6} - \frac{1}{6} = 0\\0-\frac{1}{6} = -\frac{1}{6}

Hence,

The next three terms are: 1/6 , 0 and -1/6

Find the 7th term in the sequence -10,-6,-2,2...
jeyben [28]

1st term = -10

2nd term = -6

3rd term = -2

4th term = 2

5th term = 6

6th term = 10

7th term = 14


The reason how I got 14 for the 7th term is because, i added 4 to each term.


Hope this helps!
