Write the equation of the line that passes through the points (-8,3) and

Mathematics
1 answer:
enyata [817]3 years ago
3 0

Answer:

Slope of a line can be found by

y~2 - y~1 / x~2 - x~1

The coordinates given are (-8,3) and (3,2)

2 - 3 / 3 - (-8) = - 1/11 this is your Slope, m

Use the Slope and either point to find b by substituting x and y and m values we know into

y=mx+b

2 = -1/11(3) + b simplify

2 = - 3/11 + b isolate b by adding 3/11 to both sides

22/11 + 3/11 = b = 25/11

Use m and b to write your equation.

y= - 1/11x + 25/11

The function g(x) = p sin x +q, where p>0, has a maximum value of 10 and a minimum value of -4. Find the value of p and of q.
tester [92]

Answer: p=7, q=3

Step-by-step explanation:

The midline of the function is

\frac{10-4}{2}=3 \implies q=3

This means that to obtain a maximum of 10, when \sin x reaches it's maximum, 1, g(x)=p+q=10 \implies p=7

Charlie watched 1 3 of a movie in the morning, and he watched some more at night. By the end of the day, he still had 2 5 of the
Finger [1]

Answer: 4/15 of the movie

Step-by-step explanation:

In the morning, Charlie watched ¹/₃ of a movie. He then watched some more at night.

At the end of the day, he still had ²/₅ of the movie to watch.

The proportions of an item must always add up to one. This means that if you added the 1/3 to the 2/5 and then to the fraction Charlie watch at night, they should add up to one.

¹/₃ + ²/₅ + x = 1

x = 1 - ¹/₃ - ²/₅

x = \frac{15 - 5 - 6 }{15} \\\\x = \frac{4}{15}

patriot [66]

9514 1404 393

Answer:

  15.71 units

Step-by-step explanation:

The arc length is given by the formula ...

  s = rθ

where r represents the radius, and θ represents the central angle in radians.

The angle of 60° is π/3 radians, so the arc length is ...

  s = 15(π/3) = 5π ≈ 15.71 . . . units

  LN ≈ 15.71 units

__

<em>Note</em>: if you use 3.14 for π, you will get 15.70.
