Answer: 30, 6900, 6900

Step-by-step explanation:

The break-even point is when cost equals revenue.

[tex]230x=200x+900\\\\30x=900\\\\x=30[/tex]

The cost and revenue at x=30 are both $6900.

Thus, t has a greater value than s for the co-ordinates (s, -1) and (t, 3).

How to analyze points of an axis for a two dimensional entity?
We can use the fact that both points on the x-axis to compare the values of s and t for the provided parallelogram. As a result, each point that is closest to the x coordinate reflects a higher value than its equivalent counterparts.

Given, the co-ordinates of the parallelogram are: (-2, 3), (s, -1), (0, -1),
(t, 3).
Also, the co-ordinates of the parallelogram are also shown in the figure below.
To compare for the values of s and t for the given parallelogram,
we can analyze that both s and t represent points on the x-axis, therefore any point that stands rightmost with the x co-ordinate represents a higher value than the corresponding counterparts.
Therefore, t has a greater value than s for the co-ordinates (s, -1) and (t, 3), since t is on the right side from s.

Carmella has 9 albums and 4410 cards.

The unitary approach involves calculating the value of a single unit, from which we can calculate the values of the necessary number of units.

Due to that,

There are 315 cards in each box.

14, the number of boxes.

(b) Total number of cards is the sum of the boxes plus the number of cards in each box.

= 14 × 315

= 4410

(a) Carmella purchased a six-album set of 500 cards since she thought she had 3,000 cards. Six albums are not enough because she calculated the quantity of cards incorrectly. There are 4410 cards in total, but she thought there were only 3000.

(c). Total number of albums required = [tex]\dfrac{Total number of cards}{Number of card 1 album can hold}[/tex]

                                                             = [tex]\frac{4410}{500}[/tex]

The perimeter of the square has a value of 260 units

From the question, the given parameters are

Shape = Square

Side lengths = 9x + 11 and 13x - 1

The side lengths of a square are congruent

This means that

9x + 11 = 13x - 1

Collect the like terms in the equation

So, we have

13x - 9x = 11 + 1

Evaluate the like terms

2x = 12

Divide both sides by 2

x = 6

The perimeter of the square is then calculated as

P = 4 * (9x + 11)

Where x = 6

So, we have

P = 4 * (9 x 6 + 11)

Evaluate

P = 260

Hence, the perimeter is 260 units

Adding the two equations will be adding similar terms to both equations. That is:

8x + (-8x) = 0

Therefore, adding the two equations will look like -16y = 16. (Option 3)

Based on the calculations, the value of function g(f(x)) is equal to: g(f(x)) = x + 10.

A function can be defined as a mathematical expression which is used to define and represent the relationship that exists between two or more variables. This ultimately implies that, a function is typically used for uniquely mapping an input variable (x-value) to an output variable (y-value).

In this exercise, you're required to determine the value of g(f(x)) and we are given the following functions:

f(x) = (x + 3)²        ........function 1.

g(x) = √x + 7        ........function 2.

Next, we would substitute function 1 into function 2 as follows:

g(f(x)) = √((x + 3)²) + 7

g(f(x)) = (x + 3) + 7

g(f(x)) = x + 3 + 7

g(f(x)) = x + 10

Lexi opened her account with less money and accrues interest at a greater rate.

What is meant by interest?

In the fields of finance and economics, interest is the payment made at a set rate by a borrower or deposit-taking financial institution to a lender or depositor in excess of the principle amount (the amount borrowed). The charge that the borrower may be required to pay the lender or another entity is not the same as interest. Interest also differs from dividends, which are distributed by businesses to their shareholders from their profits or reserves, but not at a set rate but rather on a pro rata basis as a portion of the rewards received by risk-takers when revenue generated exceeds total expenditures. The amount of interest paid or received during a specific time period divided by the total amount borrowed or lent is the rate of interest.

The dimensions of your mowing plot if x = 13 meters is;

Length = 31 meters

Width = 36 meters

We are told that Your plot has a length which is five more than two times x and the width is three less than three times x

This means that, the length given as words is "5 more than 2 times x" and the width given as words is "3 times x minus 3"

The expression for length would be  2x + 5

The expression for width would be 3x - 3

Now, if x = 13 meters, then we see that;

Length = 2(13) + 5 = 31 meters

Width = 3(13) - 3 = 36 meters

The equation that represents the total average decrease in the stock after 4 weeks is 4|−12| = 48 dollars.

When the value of a stock decreases, the number is a negative number. A negative number is a number that is less than zero. A negative number would have a negative sign in front of it. Thus, a $12 stock decrease would be written as -12.

The total stock decrease in 4 weeks can be determined by multiplying $-12 by 4 weeks. Multiplication is the operation that is used to determine the product of two or more numbers.

Total stock decrease = decrease per week x number of weeks

-12 x 4 = -48 or |-48| dollars

We are given an equation that represents the path of the longest shot put by the women's track team as:

Where x represents the horizontal distance from the start and h(x) is the height of the shot put above the ground.

Solution:

(a) The vertex of the model:

Method 1: We can plot the model on a graph and identify the vertex from the graph. The vertex is the lowest/highest point on the curve.

The graph is shown below:

From the graph, we can see that the vertex of the model is : (31.765, 22.953)

Method 2: The vertex of the model can also be calculated using the formula:

First, we find the x-coordinate using the formula:

Substituting, we have:

The y-coordinate of the vertex can be obtained by substituting the x-coordinate into the model. So, we have the y-coordinate to be:

Hence, the vertex is : (31.765, 22.953)

(b) The maximum height

The horizontal distance of the maximum height of the shot put from the starting point is :

From the plot, the starting point is -4.98

The maximum height of the shot put is 22.953 feet, 36.745 feet away from the starting point.

(c) The vertical intercept

The vertical intercept is the point where the curve cuts the y-axis.

From the graph, the point is (0, 5.8).

At this point where the horizontal distance is 4.98 feet away from the starting point, the shot put is 5.8 feet above the ground.

(d) The distance from the starting point to when the shot-put stikes the ground is:

From the plot, the intercepts on the x-axis are (-4.98, 0) and (68.509, 0).

Hence, the distance is:

Let's assume that we have a circle of radius r. Its circumference or perimeter C and its surface area A are given by the following formulas:

We must find the radius or diameter of a circle where C and A are equal. Then we can construct an equation for r by equalizing A and C:

We can divide both sides by π and r (it is important to note that we can divide by r because we know that r is not 0). Then we get:

So the radius is 2 (of any unit). Then the answer is the first option.

Answer: Radius = 5.33

Diameter = 10.66

Area = 89.3

Step-by-step explanation:

Circumference = 2πr

33.5 = 2πr

r = 33.5 / 2π

Diameter = 2r

Area = r²π

Area = 5.33²π
