How can you use the point-slope form of a line when only given two points?

Mathematics
1 answer:
pshichka [43]3 years ago
3 0

Answer:

See below

Step-by-step explanation:

<u>Point -slope form is:</u>

  • y - y1 = m(x - x1)

By having one set of coordinates and knowing the value of the slope (m in the equation) you can use the form.

<u>How to find the slope?</u>

Here you need 2 points: Point 1 with coordinates x1, y1 and point 2 with the coordinates x2, y2

<u>Use the formula:</u>

  • m = (y2-y1)/(x2-x1)

<u>Example:</u>

  • m = -5, and one of the points has coordinates (9, 2) then point-slope form is:
  • y - 2 = -5(x - 9)

What is the focus of the following graph?
diamong [38]

Answer:

F(1,5)

Step-by-step explanation:

This is a vertical parabola.

The vertex is at (1,4).

The directrix is y=3.

The distance from the vertex to the directrix is p=1

The focus is (1,4+p), which is (1,4+1)

Therefore the focus is (1,5)

PLEASE HELP ME PRE CAL/TRIG
miss Akunina [59]

Answer:

A) 60 Degrees

B) 550 Feet

C) 2.5 minutes

Step-by-step explanation:

a) So the wheel has completed one revolution in 10 minutes so lets first divide 100 secs with 10 minutes to calculate the the fraction of revolution

1 min = 60 secs

10 min = 600 secs

100/600 = 1/6

One complete revolution is 360 degrees and 1/6 of 360 degrees will be 60 degrees .

360/6 = 60°

b)  It takes 10 minutes to complete one revolution so if the person is on it for 7 minutes it would be 7/10 of a revolution . The ferris wheel has a diameter of 250 feet so the radius will be 125 feet because it is the half of the diameter and the circumference will be 250 π . To calculate the distance lets multiple the fraction of the revolution which is 7/10 into the circumference \frac{7}{10} * (250 pi) = 550 Feet.

C)It took 10 minutes to travel 250 π now we will use this relation to calculate 200 feet . lets suppose t is for time .

\frac{250pi}{10} =\frac{200}{t}.

After solving this equation as there is only one unknown which is "<em>t</em> "the answer will be 2.5 minutes.
