Can anyone answer this question???

Leona [35]

Answer:

E = 216 joules

Step-by-step explanation:

The given equation is

E = $\frac{m*v^{2} }{2}$ ............(i)

Here

m = 3 kg

v = 12 m/s

Putting the given values in equation (i)

E = $\frac{3*12^{2} }{2}$

E = $\frac{3*144}{2}$

E = $\frac{432}{2}$

E = 216 kg m² /s²

or

E = 216 joules

What are the roots of the quadratic equation x2+2x=-5

stiks02 [169]

Answer:

x = -1 +/-2i

Step-by-step explanation:

Write the equation in standard form to find the roots, also known as the solutions, zeros, or x-intercepts, of the quadratic.

x² + 2x + 5 = 0

Use the quadratic formula by substituting a= 1, b = 2 and c = 5.

$x = \frac{-2 +/- \sqrt{(-2)^2 - 4(1)(5)} }{2(1)} = \frac{-2 +/-\sqrt{4 -20 } }{2} = \frac{-2 +/-\sqrt{-16 } }{2} = \frac{-2 +/-4i }{2} = -1 +/-2i$

10/13 = 8 - 2z/52 Thats the question. Im dyin for help. :)

svp [43]

Answer:

z = 188

Step-by-step explanation:

1. 10/13 = 8 - 2z/52 (simplify - 2z/52)

10/13 = 8 (- 1/26)*z

2. 10/13 = (- 1/26)*z + 8 (flip for ease in solving)

(- 1/26)*z + 8 = 10/13

3. (- 1/26)*z + 8 = 10/13 (inverse: subtract 8 from each side to isolate variable <em>z</em>)

(- 1/26)*z = 10/13 - (8*13)/(1*13) (common denominator needed for add/subtract)

(- 1/26)*z = - 94/13 (simplify)

4. (- 1/26)*z = - 94/13 (inverse: multiply both sides by -26/1 to isolate variable <em>z</em>)

<h2>z = 188</h2>
