The rhombus has a area of 24 square centimetres.

The area of a rhombus can be found using the formula A = (d1 x d2)/2, where d1 and d2 are the lengths of the diagonals of the rhombus.

In this case, we are given the side length of the rhombus as 5 cm and its altitude as 4.8 cm. The altitude is the height of the rhombus, which is perpendicular to the side and bisects it. Therefore, we can use the altitude and the side to find the lengths of the diagonals.

The length of one diagonal is twice the length of the altitude, so we have:

d1 = 2 × 4.8 = 9.6 cm

To find the length of the other diagonal, we can use the formula for the area of the rhombus:

A = (d1 x d2)/2

Rearranging this equation, we get:

d2 = (2A)/d1

Substituting the given values, we get:

d2 = (2 × 5 × 4.8)/9.6

d2 = 5 cm

Therefore, the length of the other diagonal is also 5 cm.

Now that we know the lengths of the diagonals, we can use the formula for the area of the rhombus:

A = (d1 x d2)/2

Substituting the values we found, we get:

A = (9.6 × 5)/2

A = 24 cm²

Therefore, the area of the rhombus is 24 square centimeters.

Taking into account the definition of a system of linear equations, the cost of one ticket is $11 and the cost of one tub of popcorn is $6.

A system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.

In the systems of equations, the values of the unknowns must be found, with which when replacing, they must give the solution proposed in both equations.

In this case, a system of linear equations must be proposed taking into account that:

You know that:

The system of equations to be solved is

4t + 2p= 56

3t + 3p= 51

There are several methods to solve a system of equations and it is decided to solve it using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.

In this case, isolating the variable "p" from the first equation:

2p= 56 - 4t

p= (56 - 4t)÷ 2

p= 56÷2 - (4÷2)t

p=28 -2t

Replacing this expression in the second equation:

3t + 3×(28 -2t)= 51

Solving:

3t + 3×28 -3×2t= 51

3t + 84 -6t= 51

3t -6t= 51 - 84

-3t= -33

t= (-33)÷(-3)

t= 11

Remembering that p=28 -2t, you get:

p=28 -2×11

p=28 - 22

p= 6

In summary, each ticket cost $11 and each tub of popcorn cost $6.

Therefore, there are 53,248 different super subs that can be made if there are 8 toppings, 6 condiments, and 6 types of homemade bread to choose from at Sandwich Station.

The super sub at Sandwich Station consists of 4 different toppings and 3 different condiments. The question is asking how many different super subs can be made if there are 8 toppings, 6 condiments, and 6 types of homemade bread to choose from.

To solve this problem, we can use the multiplication principle of counting. The multiplication principle states that if there are m ways to do one thing and n ways to do another thing, then there are m x n ways to do both things.

Let's use the multiplication principle to solve this problem. There are four different toppings, and we can choose any of the eight toppings for each of the four spots.

Using the multiplication principle, there are

8 x 8 x 8 x 8 = 4096

ways to choose the toppings. Similarly, there are

6 x 6 x 6 = 216

ways to choose the condiments. Lastly, there are 6 different types of homemade bread to choose from. Using the multiplication principle again, there are

4096 x 216 x 6 = 53,248,

which means there are 53,248 ways to make the super subs.

Answer: x= 16

Step-by-step explanation:

Solve for x

√(5x + 1) − √x = 5

Add √x to both sides of the equation.

√(5x + 1)^2 = 5( + √x )^2

To remove the radical on the left side of the equation, square both sides of the equation.

√5x + 12 = (5 + √x)^2

Simplify each side of the equation.

5x + 1 = 25 + 10√x + x

Solve for 10√x.

10√x  = 4x − 24

To remove the radical on the left side of the equation, square both sides of the equation.

(10√x)^2 = (4x − 24)^2

Simplify each side of the equation.

100x  = 16x^2 − 192x + 576

Solve for x.

x = 9/4 , 16

B. Both functions are decreasing, but function g is decreasing at a faster average rate on that interval.

Let's clarify the comparison between the functions f(x) and g(x) and explain the rates of decrease more accurately.

The given table represents the values of function g(x) for different values of x: x = 0, 1, 2, 3, 4.

The corresponding values of g(x) are 75, 43, 27, 19, and 15, respectively.

Function f is described as an exponential function that has an initial value of 64 and decreases by 50% as x increases by 1 unit.

However, we don't have the specific values of f(x) for the interval [0, 4].

So, we cannot compare the exact values of f(x) and g(x) directly.

Now, let's compare the average rates of decrease between the two functions:

For function f, we know that it decreases by 50% as x increases by 1 unit. This means that for every unit increase in x, the value of f(x) decreases by half of its previous value.

On the other hand, for function g, we can observe the values in the table. As x increases from 0 to 1, g(x) decreases from 75 to 43.

This is a decrease of 32, which represents a decrease of (32/75) \(\times\) 100% ≈ 42.67%.

From the given information, we can conclude that function g is decreasing at a faster average rate compared to function f on the interval [0, 1].

However, without further information or additional data points, we cannot make a definitive comparison for the entire interval [0, 4].

Therefore, the correct statement regarding the comparison of the two functions on the interval [0, 4] would be:

B. Both functions are decreasing, but function g is decreasing at a faster average rate on that interval.

Answer:

1) C. 4 - 3·i

2) D. The second graph shares the same vertex, is inverted, and opens wider than the first graph

3) C. y = (x - 2)² + 3 would shift right two units

4) B. Figure B' is congruent but not similar to figure B

5) A. m∠k' = m∠k

Step-by-step explanation:

1) Given that the real part of the complex number = 4

The imaginary of the complex number = -3

The general form of representing complex numbers is z = a + b·i, we have;

The binomial equivalent to the complex number is z = 4 - 3·i

2) The first graph equation is y = 2·x²

When x = 1, y = 2 and when x = 2, y = 8

The vertex = (h, k)

Where;

h = -b/(2.a) and b = 0, a = 2

∴ h = 0/(2 × 2) = 0

h = 0

k = f(h) = f(0) = 2 × 0² = 0

k = 0

The vertex, (h, k) = (0, 0)

The coefficient, 'a' is positive, therefore, the graph opens down

The second function, y = -(1/2)·x² also has a vertex (h, k) = (0, 0)

The coefficient, 'a' is positive, therefore, the graph opens up

When x = 1, y = -1/2 and when x = 2, y = -2

Therefore, the second function is wider

Therefore;

The second graph shares the same vertex, is inverted, and opens wider than the first graph

3) The given functions are;

First function; y = x² + 3 and second function; y = (x - 2)² + 3

First function;

When x = 1, y = x² + 3 = 1 + 3 = 4

∴ When x = 1, y = 4

Second function;

When y = 4, y = 4 = (x - 2)² + 3

√(1) = x - 2

x = 3

∴ When x = 3, y = 4

First function;

When x = 2, y = x² + 3 = 4 + 3 = 7

∴ When x = 2, y = 7

Second function;

When y = 7, y = 7 = (x - 2)² + 3

√4 = 2 = (x - 2)

x = 2 + 2 = 4

x = 4

∴ When x = 4, y = 7

Therefore, the second function, y = (x - 2)² + 3, has the x-value shifted 2 units to the right for a given value of 'y'

4) The lengths of the sides of figure B are 3 by 4, the lengths of the sides of figure B' 4.5 by 6

The ratio of the corresponding length and width of figures B and B' are;

3/4.5 = 4/6

Therefore, figure B' is similar but not congruent to figure B

5) A rotation and a reflection are rigid transformations and therefore, the dimensions and measure of the original figure and the image are the same;

∴ m∠k' = m∠k.

2. 120 student's didn't vote

3. 7 quarters

Step-by-step explanation:

1. first, see how many games can be played:

45÷3 = 15

then, multiply the number of games by two because 2 students can play per game

15 • 2 = 30

2. first, figure out what percent of students did not vote:

  100 - 60 = 40%

  then, multiply the number of students total (300) by the decimal of the percent that did not vote to find the number of students who didn't vote:

    300 • .40 = 120 student's didn't vote

3. first, find how much 9 dimes is:

   1 dime = $0.10

1. The equation to slope-intercept form is y = -2/3(x) + 490. The slope is -2/3 and the y-intercept is 490.

2. You should start at the y-intercept (0, 490) and move right by 3 units and downward by 2 units, and then connect the points.

3. The equation in function notation is f(x) = -2/3(x) + 490. The graph of the function is the rate of change with respect to the number of sandwich lunch sold.

4. A graph of the function with intercepts is shown below.

5. The graphs of the functions for the two months both have the same slope but different y-intercept and x-intercept.

In Mathematics and Geometry, the slope-intercept form of the equation of a straight line is given by this mathematical equation;

y = mx + b

Where:

Based on the information provided above, a linear equation that models Sal's Sandwich Shop's profit is given by;

2x + 3y = 1,470

By subtracting 2x from both sides of the equation and dividing by 3, we have:

2x + 3y - 2x = 1,470 - 2x

y = -2/3(x) + 490

Therefore, the slope is -2/3 and the y-intercept is 490.

Part 2.

In order to graph the equation by using the slope-intercept method, you would start at the y-intercept (0, 490) and move right by 3 units and down by 2 units, and then connect the points.

Part 3.

Next, we would write the equation in function notation as follows;

f(x) = -2/3(x) + 490

The graph represents the rate of change of the function with respect to the number of sandwich lunch sold.

Part 4.

In this context, we would use an online graphing calculator to plot the linear function as shown in the image attached below.

Part 5.

Assuming Sal's total profit on lunch specials for the next month is $1,593 and the profit amounts remain the same, a system of equations to model this situation is given by:

2x + 3y = 1593; y = -2/3(x) + 531.

2x + 3y = 1,470; y = -2/3(x) + 490.

In conclusion, we can logically deduce that the graphs of the functions for the two months both have the same slope but different y-intercept and x-intercept.

The area of triangle EFG, to the nearest square inch, is approximately 1061 square inches.

To find the area of triangle EFG, we can use the formula:

\(Area = (1/2) \times base \times height\)

In this case, the base of the triangle is FG, and the height is the perpendicular distance from vertex E to side FG.

First, let's find the length of FG. We can use the law of cosines:

FG² = EF² + EG² - 2 * EF * EG * cos(∠F)

EF = 72 inches

EG = 34 inches

∠F = 21°

Plugging these values into the equation:

FG² = 72² + 34² - 2 * 72 * 34 * cos(21°)

Solving for FG, we get:

FG ≈ 83.02 inches

Next, we need to find the height. We can use the formula:

height = \(EF \times sin( \angle F)\)

Plugging in the values:

height = 72 * sin(21°)

height ≈ 25.52 inches

Now we can calculate the area:

\(Area = (1/2) \times FG \times height\\Area = (1/2)\times 83.02 \times 25.52\)

Area ≈ 1060.78 square inches

The graph of the equation is showing that we are walking towards our home. If the equation d = 4 - (1/15)t represents your distance from home d for each minute you walk t .

A line's steepness and direction are determined by the slope of the line. Without actually using a compass, determining a line's slope in a coordinate plane allows one to anticipate whether a line is parallel, perpendicular, or not.

The change in a line's y coordinate relative to its change in x coordinate is referred to as the line's slope. Δy is the net change in the y coordinate, while Δx is the net change in the x coordinate.  

Therefore,

m =  y₂-y₁/x₂-x₁ (where m denotes the slope) can be used to express how the y coordinate changes in relation to the x coordinate.

Be aware that tan ∅ = y/x

We also refer to this tan as the line's slope

We have given d = 4 - (1/15)t

We will use the graph tool and determine the coordinates
