Can someone explain to me what rate of change is and how you figure it out.

Mathematics

ROC is often used when speaking about momentum, and it can generally be expressed as a ratio between a change in one variable relative to a corresponding change in another; graphically, the rate of change is represented by the slope of a line.

In the expression 3x²y + 4x – 5x’y, are the terms 3x’y
Sidana [21]

Answer:

Yes. 3x²y and -5x²y are like terms because the variables x and y have the same exponents.

I need some serous help immediately
stepladder [879]
I’m assuming you are talking about number four. If you look at the line it provides you, the slope is -.5 and the intercept is zero. So all you have to do is rewrite the equation but subtract four from the right side and it will be parallel.

I really need a good explanation on how to solve this, not just the answer please please please..
Alchen [17]

Answer:

Step-by-step explanation:

94

Mean = add all the numbers up and divide by how many numbers you added

So add (x +120  + 112 + 130 + 128 + 124 ) divided by 6  =118

x is the score you are looking for and 118 is the average he wants

so (x + 614 ) divided by 6 =118

now multiply both sides by 6

x + 614 = 118 times 6

x + 614 = 708

subtract 614 from both sides

x = 94

The measurement of a central angle is 75. Find the measurement of <br> in radians
Marina CMI [18]
Circumference = 360 degrees 
<span>Circumference = 2π radians (comes from 2*pi*radius) </span>

<span>Therefore </span>
<span>360 deg. = 2*π radians </span>
<span>180 deg. = π radians </span>
<span>1 deg. = (π/180) radians </span>

<span>75 deg. = 75(π/180) radians </span>
<span>75 deg. = 75π / 180 radians </span>
<span>don't bother to try and simplify π (it is an irrational number) </span>
<span>however you can simplify 75/180 </span>
<span>both are divisible by 5 </span>
<span>75π/180 = 15π/36 </span>
<span>both are divisible by 3 </span>
<span>75 deg. = 5π/12 radians </span>

<span>We normally don't bother to go further, unless you actually need it as a decimal fraction (in which case, you will have an approximation) </span>

<span>75 deg. ≈ 1.308997 radians</span>

What number must you add to complete the square?
eimsori [14]

Answer:

36

Step-by-step explanation:

x^2 + 12 x  = 40

To complete the square, take the coefficient of the x term

12

Divide by 2

12/2 = 6

Square it

6^2 = 36

Add 36 to each side
