Been trying to get this one answered for months, will make the first one to answer a brainliest :D Please explain how you did it

Nikitich [7]

Answer:

$\frac{2}{7}$

Step-by-step explanation:

In order to find the slope of a line you must find where the points intersect, use the formula for slope, substitute values, and simplify if needed.

In this case we were already given the points for slope:

$P1=(-4,-4) = (x1,y1)$

$P2=(-2,3)=(x2,y2)$

Slope formula:

$slope = \frac{y2-y1}{x2-x1}$

Now substitute:

$\frac{-2--4}{3--4}$

Solve using KCC: (Keep, Change, Change)

$-2+4=2$

$3+4=7$

= $\frac{2}{7}$

Because the slope isn't a negative you do not need to simplify the answer.

Hope this helps.

A boat is spotted in the water with an angle of depression of 25° from the top of a lighthouse that is 89 feet tall. To the near

stepan [7]

To calculate this you need to imagine triangle which points are:
boat
Top of lighthouse
Bottom of lighthouse

That triangle has 90 degrees angle at bottom of lighthouse. That means that we can use trigonometry to determine length between boat and bottom of lighthouse

tan(25) = 89/x
x = 89/tan(25)
x = 190.86

after rounding, the answer is D, 191 feet

Figure ABCD is rotated clockwise about the origin through 90°. Identify the coordinates for the given figure after 90° rotation

nydimaria [60]

Answer:

D[3, 3], C[1, 4], B[0, 1], A[4, -1]

Step-by-step explanation:

Whenever you are doing a 90° clockwise rotation ABOUT THE ORIGIN, it is in the form of [y, -x], meaning you take the y and make it your x, then take your original x and put its OPPOSITE.

90° counterclockwise rotation → [-y, x]

90° clockwise rotation → [y, -x]

I hope this helps, and as always, I am joyous to assist anyone at any time.
