A and D have the same rate of change, which is 0.5.

Generally, The term "rate of change" (ROC) refers to the rate at which something varies over a period of time.

Therefore, the size of individual changes is not as important as the pace at which they are occurring or the rate at which they are accelerating or decelerating.

When it comes to financing, understanding price returns and recognizing momentum in trends may both be accomplished via the usage of rate of change.

Radical expressions are numbers which have root values in them. The root can be an nth root, a square root, or a cube root. To simplify the radical expressions we can use the product property.

We first locate the radicand's greatest factor which is also a perfect power of the index.

Then we use that factor to rewrite the radicand as the product of two factors. Rewrite the radical as the result of two radicals by applying the product rule and then reduce the perfect power to its most basic form.

To simplify the radical expressions we can use the quotient property. Make the fraction in the radical simpler then rewrite the radical as the quotient of two radicals by using the Quotient Property. Radicals in the numerator and denominator should be made simpler.

The slope of the line 3x - 4y = -12 is 3/4, obtained by dividing -3 by -4 after isolating y.

What is slope ?

Slope, also known as gradient, is a measure of the steepness of a line. It is the ratio of the change in the y-coordinate to the change in the x-coordinate between any two distinct points on the line. It is represented by the letter "m" in the slope-intercept form equation of a line y = mx + b, where m is the slope, x is the independent variable, y is the dependent variable and b is the y-intercept, the point where the line crosses the y-axis.

The slope of a line can be found by rearranging the equation to the slope-intercept form y = mx + b. To find the slope of the equation 3x - 4y = -12, you can divide both sides by -4 and then divide by 3.

3x - 4y = -12

-4y = -3x -12

y = (3/4)x +3

Answer:

  The square of x, or x times x.

Step-by-step explanation:

You want to know the meaning of x2.

As often seen on Brainly, and in poorly-edited math curriculum materials, the expression x2 is a badly-formatted version of x². It is often the result of a copy/paste operation in which the superscript text formatting is lost.

The superscript 2 is an "exponent." It tells you how many times x is a factor in the product:

  x² means x·x . . . . . a product in which x is a factor 2 times.

When superscript characters are not available, an exponent is usually signified in plain text using a caret (^) symbol:

  x² ⇔ x^2

Please note that superscript text acts to group expressions that are part of an exponent:

  [tex]x^{a+b}[/tex]

If you write this as x^a+b, it looks like b is added to the value of x^a. The expression above would be correctly written in plain text as x^(a+b), using parentheses to do the grouping that would otherwise be provided by the superscript font.

The shaded areas therefore cover a total area of 86.84 cm2.

Let's calculate the whole trapezoid's area. You multiply by the height after adding the top and bottom sides and dividing the result by two.

To get the length of the top side, we sum the values that make up that side.

6.4+5.2+9.6=21.2

The underside is 5.2.

The top and bottom sides are added.

21.2+5.2=26.4

We multiply by 2.

26.4/2=13.2

We increase by the height, which is 6.2 as we can see.

13.2×9.1=120.12

Next, we locate the rectangle's unlit portion.

6.4×5.2 = 33.28

To get the total area of the two shaded triangles, we deduct this from the trapezoid's overall area.

120.12 - 33.28 = 86.84

What is the Division?

Division is a mathematical operation used to find the number of times one number, known as the dividend, is contained within another number, known as the divisor. It is represented by the symbol "/" or the word "divided by". It is the inverse operation of multiplication.

To determine when the populations of Rock Hill and Greenville will be the same, we need to find the difference in population growth between the two cities and divide it by the difference in population growth rate. We can use the following formula:

(Population of Rock Hill - Population of Greenville) / (Population growth rate of Rock Hill - Population growth rate of Greenville) = Number of months until populations are equal

First, we will calculate the population growth rate of Rock Hill and Greenville:

Population growth rate of Rock Hill = (100 people move in) - (150 people move out) = -50 people/month

Population growth rate of Greenville = 200 people move in/month

Now we can use this information to calculate the number of months until the populations are equal:

(70,000 - 61,000) / (-50 - 200) = (9,000) / (-250) = 36

It will take 36 months for the populations of Rock Hill and Greenville to be the same.

To calculate Talia's gross pay for a week, we need to know how many hours she works per day and her pay rate.

Gross pay refers to the total amount of money an employee earns before any deductions or taxes are taken out. It is the total amount of money earned by an employee for the hours worked, including any overtime or bonuses.

You've provided that information:

Talia works 6 hours per day on Fridays and Saturdays each week.

Her pay rate is $8.20 per hour.

First, we need to find out how many hours she works a week. As she works 6 hours on Friday and 6 hours on Saturday, the total hours she works in a week is 6 hours/day x 2 days/week = 12 hours/week.

Next, we need to multiply her hourly rate by the number of hours she works per week to find her gross pay. Her pay rate is $8.20/hour and she works 12 hours/week, so her gross pay is:

$8.20/hour x 12 hours/week = $98.40/week

So, Talia's gross pay for a week is $98.40.

Answer:

  82°

Step-by-step explanation:

You want the unmarked remote interior angle of a triangle, given that one of them is 61°, and the exterior angle opposite is 143°.

The exterior angle is the sum of the remote interior angles:

  143° = 61° +∠B

  ∠B = 143° -61° . . . . subtract 61°

  ∠B = 82°

__

Additional comment

In case you don't remember the remote interior angles theorem, you can get the same result using angle relations you do remember:

The interior angle at A is the supplement of the exterior angle:

  ∠A = 180° -143°

When ∠A is added to the other two interior angles, the total is 180°:

  ∠A +∠B +61° = 180°

  (180° -143°) +∠B +61° = 180° . . . . . . use the above expression for ∠A

Rearranging this to give the value of angle B, we have ...

  ∠B = 180° -180° +143° -61°

  ∠B = 143° -61° = 82° . . . . . . as above

Another way to get there is to consider ...

  The sum of ∠B and 61° is supplementary to interior angle A (their total is 180°). The exterior angle 143° is supplementary to interior angle A. Two angles supplementary to the same angle are equal, so the sum of ∠B and 61° is equal to the exterior angle 143°.
