Write in point slope form the equation of a line that has the slope of -4 and the passes

densk [106]

Answer:

point slope form is below. since you have the slope already, all you have to do is plug in the point for x1 and y1 and then the slope for m

y - y1 = m(x -x1)

y - 2 = -4 (x - 2) (this is the equation)

Get x by itself
add 16 to both sides, so 4x = 16
divide both side by 4 and x =4

Explanations not just answers: Sarah measures the angle of elevation to the top of a tree as 23.6 degrees from the point which i

Reika [66]

See the attached diagram.

In the right triangle, x is opposite the 23.6 degree angle, and the adjacent side is 250 m. This suggests using the tangent ratio.

$\frac{x}{250}=\tan 23.6 ^\circ \\ x=250 \cdot \tan 23.6^\circ \approx 109.2$

Finally, to get the height of the tree, add Sarah's height, 1.5 m.

The tree is approximately 110.7m tall.
