Answer:

First and Third

Step-by-step explanation:

The graphs obey the function equations but the intervals are marked incorrect in #s 2 and 4

One thing to keep in mind is that when you have a piecewise function valid on certain intervals, the circle shape denoting the beginning of the interval is very important

If it is a filled circle it denotes a ≤ (or ≥) inequality

If it is an unfilled (hollow) circle it denotes a < (or >) inequality

Looking at the second graph we see that

f(x) = -1 for -∞ < x < -1
Assuming the interval is correctly defined, that solid circle at x = -1, y = -1 should be a hollow circle not a filled circle

Similarly for f(x) = 3x² + 3, the interval is given as -1 ≤ x < ∞ but the starting circle for this interval is an unfilled circle, it should be a filled circle

A similar situation applies to the fourth choice and you should be able to figure that out yourself

Using percentage, we calculated that the total number of employees in the company equals 45954.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means.

Given,

34.6% of the employees in the company equals 15,900

Let the total number of employees in the company = x

According to the given question,

34.6 / 100 × x = 15,900

⇒ x = 15900 × 1000 / 346

⇒ x = 45954

∴ Total employees in the company equals 45954.

The number of miles that Mark ran was 50 miles.

We can get the number of miles that Mark runs by first assigning him the figure x.

Since DeSahwn ran 40. 7 miles less than Mark, we can express this thus:

x - 40. 7 miles.

If the number of miles that DeShawn ran was 9.3 miles we can factor that into the equation as follows:

x - 40. 7 miles = 9.3 miles

x = 9.3 + 40.7

x = 50 miles.

Therefore, the total number of miles that Mark ran was 50 miles.

The correct statement regarding whether each graph represents a function is given as follows:

a. Represents a function, as each input is mapped to only one output.

b. Does not represent a function, as there are inputs mapped to two outputs.

A graph will represent a function if the graph contains no vertically aligned points, that is, each value of x is mapped to only one value of y.

Vertically aligned points mean that a value of the input x is mapped to multiple values of the output y, that is, a single input is mapped to multiple outputs which disqualify the relation as a function.

In the context of this problem, we have that:

A portion of a square and a portion of a circle were used to create this figure. The perimeter of the figure is 36.28 units.

Given that,

A portion of a square and a portion of a circle were used to create this figure.

We have to find the perimeter of the figure.

Three linear sides are measured in units of 4, 8, 8, 4.

Radius of the circular part = 4 units

Measure of a polygon's circumference equals the polygon's perimeter.

From the figure we can see,

Figure perimeter equals the sum of the lengths of the three straight lines and the circumference of the quarter circle.

Measure of linear sides = 4 + 8 + 8 + 4 = 24 units

Circumference of the quarter circle = 1/4(2πr)

=1/2×π×4

=2×π

=2×3.14

=6.28 units.

Perimeter of the figure is 30+6.28

The number of empty seats based on the arithmetic sequence in 6 minutes is 28.

It should be noted that an expression simply means the function that's given to show the relationship between the variables.

From the information, the movie theatre currently has 49 empty seats. 3 people enter every minute to fill those seats. The scenario is modeled by the arithmetic sequence:

= 46 − 3m.

In this case m = number or minutes.

The empty seats in 6 minutes will be:

= 46 - 3m

= 46 - 3(6)

= 46 - 18

= 28

1. Point slope form
2. y = -2x + 25

The formula for point slope form is:

y − y1 = m(x − x1), which is exactly what y-7=-2(x-9) is, as y1 is 7, m is -2 and x is 9.

To get this into slope intercept form, we have to solve for y/ isolate it.

y - 7 = -2 (x-9)

First, distribute the -2.

y - 7 = -2x + 18

Then add 7 on both sides to get rid of the -7.

+ 7 + 7

y = -2x+25

The equation of a line into slope-intercept form is represented as:

y = mx + c

where m = slope of the line

c = y-intercept of the line

On simplifying 8x - 20y = 40, the equation will be:

⇒ 2 (4x - 10y) = 2 (20)

⇒ 4x - 10y = 20

⇒ 2x - 5y = 10

⇒ 2x - 10 = 5y

⇒ 5y = 2x + (-10)

⇒ y = 2x/5 + (-10/5)

⇒ y = 2x/5 + (-2)

The slope of this line = 2/5

Answer:

  37.26 units

Step-by-step explanation:

You want to know the perimeter of the pentagon defined by the points (-5.5, 0), (-5.5, 7), (0, 9.7), (5.5, 7), and (5.5, 0).

The attached graph shows the points and the distances between them. The perimeter is the sum of those distances.

  7 +6.13 +6.13 +7 + 11 = 37.26

The perimeter of the polygon is about 37.26 units.

__

Additional comment

The length of the slant edges can be found using the distance formula.

  d = √((x2 -x1)² +(y2 -y1)²) = √((0 -5.5)² +(9.7 -7)²) = √(30.25 +7.29)

  = √37.54 ≈ 6.12699

The lengths of the horizontal and vertical edges can be found by differencing the x- and y-coordinates of the points, respectively. (The distance formula can be used, as well.)

An inequality  | 2n -(- 1) | ≥ 10

                          | 2n + 1 | ≥ 10

after solving the inequality we get the value of n, n ≥  4.5  and n  ≤ - 5.5                                          

According to the question, given that

An inequality which has twice a number n is no less than 10 units from −1.

then inequality : | 2n -(- 1) | ≥ 10

                             | 2n + 1 | ≥ 10

So, 2n + 1 ≥ 10                   or              2n + 1  ≤ - 10

    2n  ≥  10 - 1                                      2n  ≤ - 10 - 1

    2n ≥  9                                              2n  ≤ - 11

    n ≥  4.5                                               n  ≤ - 5.5

Therefore, we get the value n, n ≥  4.5 and n =  ≤ - 5.5  after solving inequality.

Tom should choose the bank that gives the highest interest rate on savings accounts

The amount a lender charges a borrower is called an interest rate, and it is expressed as a percentage of the principal, or the loaned amount. Typically, a loan's interest rate is expressed as an annual percentage rate, or APR.

A savings account or certificate of deposit earnings at a bank or credit union may also be subject to an interest rate (CD). The interest received on these deposit accounts is measured in annual percentage yields. In this case, the one that gives the best rate is the best option to choose.
