zhuklara [117]

Answer:

$2\frac{3}{4}$ or 2.75, depending on what you need.

Step-by-step explanation:

Subtract $269 by the service fee ($60). This will be $209.
Divide $209 by $76 to calculate hours. This will be 2.75.
(optional) We know that 0.75 is $\frac{3}{4}$ , so let's take 2.75 and convert it into $2\frac{3}{4}$ . This is your answer.

Find sin θ and cos θ if tan θ= 1/4 and sin 0>0.

Serga [27]

Answer:

$\displaystyle \sin(\theta)= \frac{\sqrt{17}}{17}$

$\displaystyle \cos(\theta)= \frac{4 \sqrt {17} }{ 17 }$

Step-by-step explanation:

We want to find sin(θ) and cos(θ) given that tan(θ) = 1/4 and sin(θ) > 0.

First, since tan(θ) and sin(θ) are both positive, cos(θ) must be positive as well.

Recall that tangent is the ratio of the opposite side to the adjacent side.

Therefore, the hypotenuse is:

$h=\sqrt{4^2+1^2}=\sqrt{16+1}=\sqrt{17}$

So, with respect to θ, the opposite side is 1, the adjacent is 4, and the hypotenuse is √17.

Then it follows that:

$\displaystyle \sin(\theta)=\frac{1}{\sqrt{17}} = \frac{\sqrt{17}}{17}$

And that:

$\displaystyle \cos(\theta)= \frac{4}{\sqrt{17}} = \frac{4 \sqrt {17} }{ 17 }$

What is the equation of the line that is parallel to 3x-5y=7 and passes through the point (-10,8)

Goryan [66]

Answer:

$5y - 3x = 70$

Step-by-step explanation:

The given line has equation:

3x-5y=7

We need to determine the slope of this line, so we rewrite in slope intercept form.

$y = \frac{3}{5}x - \frac{7}{5}$

The slope of this line , when we compare to y=mx+c is

$m = \frac{3}{5}$

All parallel lines have the same slope.

Hence our line also has the same slope

This line passes through (-10,8).

The equation is given by:

$y-y_1=m(x-x_1)$

We substitute the slope and point to get:

$y - 8 = \frac{3}{5}(x - - 10)$

We expand to get:

$y - 8 = \frac{3}{5}x + 6$

$y = \frac{3}{5}x + 14$

$5y - 3x = 70$
