We are asked to simplify the expression <span>sin (2 arcsin (5/13)). The technique is to simplify first the inner terms inside the parenthesis. arc sin of 5/13 under the radians mode in the calculator is equal to 0.3948. This is multiplied by 2 equal to 0.7896. sin of 0.7896 is equal to 120/169. </span>

Solve for t. 4=12gt^2

ivann1987 [24]

Answer:

$t = \sqrt{ \frac{8}{g} }$

Step-by-step explanation:

We are solving for t.

$4 = \frac{1}{2} g {t}^{2}$

Multiply both sides by 2.

$8 = gt {}^{2}$

Divide both sides by

$\frac{8}{g} = {t}^{2}$

Take square root of both sides.

$t = \sqrt{ \frac{8}{g} }$

Answer:

$y_2 = (x_2 - x_1) +y_1$ .

Implied: $x_2\ne x_1$ .

Step-by-step explanation:

Get rid of the denominator by multiplying both sides of this equation with $(x_2 - x_1)$ :

$m(x_2 - x_1) = y_2 - y_1$ .

Isolate $y_2$ by moving $(-y_1)$ to the left-hand side of the equation. That is: add $y_1$ to both sides of this equation.

$m(x_2 - x_1) + y_1 = y_2$ .

By the symmetric property of equalities,

$y_2 = m(x_2 - x_1) + y_1$
