derek is practcing for a matathon by running around a track that is 440 yards long. Yesturday he ran around the track 20 times.

Alja [10]

The answer would be 5 miles. I hope this helped ^^

First, you take 440 and multiply It by 20

Then, you take the product (8800) and divide it by 1760

Which would then give you, 5

Consider the equation below. (if an answer does not exist, enter dne.) f(x) = 5 cos2(x) − 10 sin(x), 0 ≤ x ≤ 2π

jolli1 [7]

The given equation is a wave function. When plotted, the graph is shown in the attached picture. However, the unit is in degrees instead of radians. A unit of π is equivalent to 180°. This plot could determine one variable if the other is given.

A line passes through the points (-6, 4) and (-2, 2). Which is the equation of the line?

cupoosta [38]

Answer:

$\displaystyle y=-\frac{1}{2}x+1$

Step-by-step explanation:

The equation of any line in slope-intercept form is:

y=mx+b

Being m the slope and b the y-intercept.

Assume we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

$\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Two points are given: (-6,4) and (-2,2). Calculating the slope:

$\displaystyle m=\frac{2-4}{-2+6}=\frac{-2}{4}=-\frac{1}{2}$

The equation of the line is, so far:

$\displaystyle y=-\frac{1}{2}x+b$

To calculate the value of b, we use any of the given points, for example (-6,4):

$\displaystyle 4=-\frac{1}{2}(-6)+b$

$\displaystyle 4=3+b$

Solving:

b = 1

The equation of the line is:

$\boxed{\displaystyle y=-\frac{1}{2}x+1}$

We can see none of the choices is correct.

Mason has 29.8 ounces of peanuts. He eats 5 ounces of the peanuts. Then he divides the rest of the peanuts equally among 4 frien

Snowcat [4.5K]

Alright, so the first step we are gonna do to solve this problem is subtract since Mason ate 5 ounces of the peanuts and so, we need to subtract 5 out of 29.8.

29.8 - 5 = 24.8

So, now there is 24.8 ounces.

Now we move onto the next step which is division. As you can see in the question it says "Then he divides the rest of the peanuts equally among 4 friends."

24. 8 ÷ 4 = 6.2

Since the answer is supposed to be a decimal..that's your answer!

So overall, each of Mason's friends get 6.2 ounces of peanuts.

Hope this helps!

If you are needing any more help, comment below this comment for any contact of mine. I'll be glad to help!
