Answer:

5 games

Step-by-step explanation:

Answer:

6 games.

Step-by-step explanation:

    25 - 5 = 20 {We subtract 5 from 25 because craig has 25$ to spend, and are renting shoes for 5$. The rest of the money is going towards the cost PER game, shown in step 2.}

    20 divided by 4 = 6. {4$ is the cost of each game. Therefore, divide 20 by 4.}

Answer:

Step-by-step explanation:

You want to identify the graphs that go with each of these functions, along with a particular point on the curve.

The equations are written here in standard form, factored form, and vertex form. (The "factored form" is sometimes called "intercept form.") Each of these forms can be analyzed for characteristics relevant to identifying the corresponding graph.

In general, we can readily identify the opening direction, based on the sign of the leading coefficient. Depending on the form, we can also identify zeros, the vertex, and the y-intercept.

The line of symmetry (x-coordinate of the vertex) of the equation in the form ax² +bx +c is x = -b/(2a). That is, it will be left of the y-axis when the coefficients 'a' and 'b' have the same sign.

The graph of equation A will be graph 4, the only one with its vertex left of the y-axis. The y-intercept is the constant: point S = (0, 9).

Equation B has a positive leading coefficient, so opens upward. The zeros of the factors are -3 and +9, so identify the places where the graph crosses the x-axis. Graph 3 is the only one that opens upward and has x-intercepts. Point R is (9, 0).

The vertex form of a quadratic is ...

  y = a(x -h)² +k . . . . . . . vertex (h, k); leading coefficient 'a'

Equation C has its vertex at (h, k) = (3, 9) and opens upward (a>0). Graph 1 is the only one matching those characteristics. Point P is the vertex, so point P is (3, 9).

Equation D is the same as equation B, but with a negative leading coefficient. That is, it opens downward and crosses the x-axis in two places, at x = -3 and x = 9. Graph 2 is matches this description. The left zero is point Q, (-3, 0).

The initial investment of the function is 20 dollars.

The rate growth in percentage is 4%.

The investment after 10 years is 29.6 dollars.

The function \(y=20(1.04)^{t}\) represents the value y of a saving account after t years.

Therefore, the initial investment of the function is 20 dollars.

The rate growth in percentage can be calculated as follows;

rate growth in percent = 0.04 × 100

rate growth in percent = 4 %

Let's find the value of the investment after 10 years.

Therefore,

\(y=20(1.04)^{t}\)

t = 10

\(y=20(1.04)^{10}\)

\(y=20(1.48024428492)\)

y = 29.6048856984

Therefore, the investment after 10 years is as follows:

y = 29.6 dollars

Answer:

No, It should be a complete statement/ sentence

Step-by-step explanation:

The graph of y = 3 x 2^x passes through the coordinate points (2,12) and (3,24).

To write a question in the form of y=a x b^x that passes through the coordinate points (2,12) and (3,24), we need to solve for the values of a and b.

First, let's substitute the coordinates (2,12) into the equation:
12 = a x b^2

Next, let's substitute the coordinates (3,24) into the equation:
24 = a x b^3

We now have two equations with two unknowns (a and b), which we can solve using algebra.

From the first equation, we can solve for a:
a = 12 / b^2

We can then substitute this value of a into the second equation:
24 = (12 / b^2) x b^3

Simplifying this equation, we get:
2 = b

We can then substitute this value of b back into the equation for a:
a = 12 / 2^2
a = 3

Therefore, the equation of the graph that passes through the coordinate points (2,12) and (3,24) is:
y = 3 x 2^x

We can check that this equation is correct by plugging in the coordinates:
When x = 2: y = 3 x 2^2 = 12
When x = 3: y = 3 x 2^3 = 24

Answer:

Total Charge = Initial Charge + Daily Charge x Number of Days

Step-by-step explanation:

Let's assume that x is the number of days that Frank rented the car.

The initial charge for the rental is $40, which is a one-time charge, so it does not depend on the number of days.

The daily charge for x days is $35 per day. Therefore, the total charge for x days can be calculated as:

Total Charge = Initial Charge + Daily Charge x Number of Days

Total Charge = $40 + $35x

We know that Frank was charged $180, so we can set the total charge equal to $180 and solve for x:

$40 + $35x = $180

Subtracting $40 from both sides gives:

$35x = $140

Dividing both sides by $35 gives:

x = 4

Therefore, Frank rented the car for 4 days.

By using the concept of internal angles of a triangle, the solution of the system of linear equations related to the geometrical system is (x, y) = (40, 40).

In this system we have a geometrical system formed by two right triangles with a common hypotenuse. Right triangles are triangles where one of its internal angles are right angles and the sum of the measures of the internal angles within a triangle equals 180°. Then, this geometrical system can be modelled by using the following linear equations:

(x + 20) + 90 + 30 = 180         (1)

Answer:

The volume of the hollow metal pipe is approximately 72.571 cubic centimeters.

Step-by-step explanation:

The volume of the metal is the space occupied by the hollow pipe. Since it is a hollow cylinder, the volume (\(V\)), in cubic centimetres, is defined by following expression:

\(V = \frac{\pi}{4} \cdot (D_{e}^{2}-D_{i}^{2})\cdot l\) (1)

Where:

\(D_{e}, D_{i}\) - External and internal diameters, in centimetres.

\(l\) - Length, in centimetres.

If we know that \(D_{i} = 7\,cm\), \(D_{e} = 8\,cm\) and \(l = 6.16\,cm\), then the volume of the hollow metal pipe is:

\(V = \frac{\pi}{4} \cdot (D_{e}^{2}-D_{i}^{2})\cdot l\)

\(V\approx 72.571\,cm^{3}\)

The volume of the hollow metal pipe is approximately 72.571 cubic centimeters.

In the response, the following elements were included:

1. Labeling the x-axis as the input variable, age: This is important to indicate the independent variable being plotted.

2. Labeling the y-axis as the output variable, texting speed: This is crucial to indicate the dependent variable being represented.

3  Plotting the points according to age and texting speed: This involves placing the ordered pairs (age, texting speed) on the coordinate plane, with age values on the x-axis and texting speed values on the y-axis.

4. Identifying a relationship between the change in texting speed as age increases: By analyzing the plotted points and examining the pattern or trend, one can determine if there is a relationship between age and texting speed. For example, if the texting speed generally increases as age increases or if there is a linear or nonlinear relationship between the two variables.

Including all of these elements allows for a comprehensive analysis of the relationship between age and texting speed, providing a visual representation and enabling the identification of any patterns or trends.

If g(x) is the graph of f(x) where f(x) and g)(x) both are functions and f(x) is  shifted up 2 units, then the  formula for g(x) is g(x)= f(x) + 2

A function from one set X to another allocates exactly one element of the other set Y to each element of X. The set X is known as the function's domain, while the set Y is known as the function's codomain. Initially, functions were just an idealized representation of the relationship between two changing quantities.

Here, we have

Given: If g(x) is the graph of f(x) shifted up 2 units. Here f(x) and g(x) are functions.

We have to write the formula for g(x).

Shifting up 2 units means you add 2 to f(x).

Shifted right 0 unit means you subtract 0 from the argument of the function f(x) (i.e. from x).

Answer:

Step-by-step explanation:

To evaluate the expression -ax^2 + 2x + a - 5 when a = 7 and x = -5, we simply substitute these values into the expression and simplify:

-ax^2 + 2x + a - 5

When a = 7 and x = -5, this becomes:

-7(-5)^2 + 2(-5) + 7 - 5

Simplifying this expression using the order of operations (PEMDAS), we get:

-7(25) - 10 + 7 - 5

= -175 - 8

= -183

So, when a = 7 and x = -5, the value of the expression is -183.

Answer:

when a = 7 and x = -5, the value is -183.

Answer:

-8b^2 + 4b

Step-by-step explanation:

To simplify the expression (-6b^2 2b-1) + (-2b^2 + 4b), we need to combine like terms.

First, let's distribute the negative sign to the terms inside the first set of parentheses:

(-6b^2) + (-2b^1) = -6b^2 - 2b^1

Now let's combine the terms inside the second set of parentheses:

(-2b^2) + (4b) = -2b^2 + 4b

Finally, let's add the two expressions:

(-6b^2 - 2b^1) + (-2b^2 + 4b) = -6b^2 - 2b^1 - 2b^2 + 4b

Simplifying, we get:

-8b^2 + 4b = -8b^2 + 4b

The final simplified expression is: -8b^2 + 4b.

1) Note that we'll make use of the following formulas:

So the radius according to the text must be positive, so we can discard the negative value.
