Find sin, where the angle is shown<br> Give the exact value, not a decimal approximation

olga_2 [115]

Answer:

sinΘ = $\frac{24}{25}$

Step-by-step explanation:

sinΘ = $\frac{opposite}{hypotenuse}$

The opposite is 24, but we require the hypotenuse h

Using Pythagoras' identity

h² = 7² + 24² = 49 + 576 = 625 ( take square root of both sides )

h = $\sqrt{625}$ = 25

Thus

sinΘ = $\frac{24}{25}$

Solve the linear equation. 14x − 1/2 (4x+6) = 3 (x−4) − 18

LekaFEV [45]

$14x - (2x + 3) = 3x - 12 - 18 \\ 14x - 2x - 3 = 3x - 30 \\ 12x - 3 = 3x - 30 \\ 9x = - 27 \\ x = - 3$

Quick Please :) Exponents and powers

MrRissso [65]

Step-by-step explanation:

$( {4}^{ - 3} ) ^{ - 3} = {4}^{9}$

$( { - 4}^{9} ) ^{2} = ( - 4) {}^{18}$

$( {4}^{6} ) ^{ - 3} = \frac{1}{{4}^{18}}$

$( { - 4}^{9} ) {}^{2} = ( { - 4})^{18}$

$({4}^{0} ) = {4}^{0}$

Hope this is correct and helpful
