Find sin theta if theta is an angle in standard position and the point with coordinates (3, -4) lies on the terminal side of an

alisha [4.7K]

Answer:

$\sin \theta=-\frac{4}{5}$

Step-by-step explanation:

Given:

Angle is in standard position which means the starting ray is at the origin. The terminal side has coordinates (3, -4).

So, the 'x' value is 3 and 'y' value id -4.

Using Pythagoras Theorem, we find the hypotenuse.

Hypotenuse = $\sqrt{3^2+(-4)^2}=\sqrt{9+16}=\sqrt{25}=5$

Now, using the sine ratio for the angle, we have

$\sin \theta=\frac{Opposite}{Hypotenuse}\\\sin \theta=\frac{-4}{5}\\\sin \theta=-\frac{4}{5}$

Therefore, the value of $\sin \theta$ is $-\frac{4}{5}$ .

The value is negative as the point (3, -4) lies in the fourth quadrant and sine ratio is negative in the fourth quadrant,

A garage is drawn using a scale of 2 2/3 inch =6feet if the actual height is 68 ft what is the height of the garage

butalik [34]

Answer:

Step-by-step explanation:

The drawing of the garage is a smaller representation of the actual garage. A garage is drawn using a scale of 2 2/3 inch = 6feet. Let us first convert 2 2/3 inch to improper fraction. It becomes 8/3 inch.

Let us determine the unit measurement.

If 6feet = 8/3 inch,

1 foot will be 8/3 ÷ 6 = 8/3×1/6

= 8/18 inches. Therefore

if the actual height is 68 ft , then, the height of the garage on the drawing will be

68 × 8/18 = 272/9 = 30 2/9 inches

lisov135 [29]

Answer:

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept → (0, b).

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points A(0, -4) → b = -4 and B(6, 2).

Calculate the slope:

$m=\dfrac{2-(-4)}{6-0}=\dfrac{6}{6}=1$

Put the value of m and of b to the equation:

$y=1x-4$ <em>add 4 to both sides</em>

$y+4=x$
