For what x-value(s) does cos(x) = 1? -360° 0° 360° all of the above

1 answer:

7 0

Cos(x) = 1 at 0 and 2pi 360 and -360 is the same angle as 2pi so all of the above if you start at 0 and make a complete circle (360) you will be back at point 0.

irakobra [83]

Answer:

m<6 is 102°

Step-by-step explanation:

Angles that are supplementary are equal to a total of 180°.

Subtract the 78 from the 180 to find your answer.

180-78=102

Determine the standard form of the equation of the line that passes through (-5,0) and (0,-9)

bonufazy [111]

Answer:

9x+5y=-45

Step-by-step explanation:

To write the equation of a line we must have a slope and a point. To find the slope we use the slope formula and substitute (x,y) points in it as shown below:

$m=\frac{y_2-y_1}{x_2-x_1}=\frac{-9-0}{0--5}=\frac{-9}{0+5}=\frac{-9}{5}=\frac{-9}{5}$

Now that we have the slope, plug in the slope and choose one point to plug into the point slope formula. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form.

(y-0)=-9/5(x--5)

y=-9/5(x+5)

y=-9/5x-9

Now convert to standard form, Ax+By=C.

y=-9/5x-9

9/5x+y=-9

9x+5y=-45
