Isolate the v.
a = v^2/2
First multiply 2 to both sides
a(2) = v^2/2(2)
2a = v^2
Isolate the v, root both sides
√2a = √v^2
✓2a = v
✓2a = v should be your answer
Hope this helps
Answer:
C
Step-by-step explanation:
add the two x^2 parts = 10 x^2
so answer is B or C
add the constants 7 + 6 = 13 so answer C
Answer:
The equation of the perpendicular line would be y = -2/5x - 1
Step-by-step explanation:
In order to find this line, we must first find the slope of the original line. We do this by solving for y.
-5x + 2y = -10
2y = 5x - 10
y = 5/2x - 5
This shows us a slope of 5/2. TO find the perpendicular slope, we use the opposite and reciprocal. This means we negative 5/2 to get -5/2 and then we flip it to get -2/5. Now that we have this, we can use the slope and the point in point-slope form to get the equation.
y - y1 = m(x - x1)
y - 1 = -2/5(x + 5)
y - 1 = -2/5x - 2
y = -2/5x - 1
We have to find out the value of the fraction.
<u>Let us assume that:</u>
<u>We can also write it as:</u>
<u>Comparing </u>the given <u>equation</u> with <u>ax² + bx + c = 0,</u> we get:
<u>By quadratic formula:</u>
<u>But </u><u>"</u><u>x"</u><u> cannot be negative. Therefore:</u>
So, the value of the fraction is 1 + √2.
