Answer:

$\dfrac{2\sqrt{a}}{a}$

Step-by-step explanation:

$2a^{-\frac{1}{2}} =$

$= 2 \times \dfrac{1}{\sqrt{a}}$

$= 2 \times \dfrac{1}{\sqrt{a}} \times \dfrac{\sqrt{a}}{\sqrt{a}}$

$= \dfrac{2\sqrt{a}}{a}$

What is 12X-4y = -8 written in slope-intercept form?

qwelly [4]

Answer:

y = 3x + 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

12x - 4y = - 8 ( subtract 12x from both sides )

- 4y = - 12x - 8 ( divide all terms by - 4 )

y = 3x + 2 ← in slope- intercept form

Determine value of a

S_A_V [24]

For this case we have that by definition of trigonometric relations that the sine of an angle is equal to the opposite leg to the angle on the hypotenuse. That is to say:

$Sin (43) = \frac {a} {26}$

Clearing the value of "a":

$a = 26 * sin (43)\\a = 26 * 0.68199836\\a = 17.73195736$

Rounding off we have:

17.7

Option B
