The answer to your problem is A due to the slope of your line being -1/3x.

You can find this slope by picking two points on your graph [i.e. (-1,3) and (0,0)].

Find the difference between the two points, which is a one for the x value and a three for the y values. Now you have a slope of 1/3.

But wait! The slope is downwards, therefore a negative must be applied to your slope.

This provides you with a slope of -1/3x, therefore:

y = -1/3x

Find the exact values of the indicated trigonometric functions. Write fractions in lowest terms.
vodka [1.7K]

For this case we have that by definition of trigonometric relations of a rectangular triangle, that the sine of an angle is given by the opposite leg to the angle on the hypotenuse of the triangle. While the tangent of the same angle is given by the leg opposite the angle on the leg adjacent to the angle.

Then, according to the figure we have:

sin (B) = \frac {7} {25} = 0.28\\tg (B) = \frac {7} {24} = 0.2917

Answer:

sin (B) = \frac {7} {25}\\tg (B) = \frac {7} {24}

A spinner is split into 4 equal parts labeled 1, 2, 3, and 4.
ivolga24 [154]

Answer:

50%

Step-by-step explanation:

If there are 4 parts to the spinner, 4 is the whole. Since there are 2 even numbers (2&4), the fraction would be \frac{2}{4}, which is simplified to \frac{1}{2}. And because \frac{1}{2} could also turn into \frac{50}{100}, the percentage is 50%.

Hope this helps :)
