Step-by-step explanation:

if I understand correctly, then the 3 friends ordered a combo meal each.

so, 3 drinks and 3×2 = 6 slices of pizza are ordered.

and that costs in total $31.50.

each drink costs $2.50.

so, the calculation is (with x being the price of a pizza slice) :

3×2.5 + 6x = 31.5

7.5 + 6x = 31.5

6x = 24

x = 4

so, each slice of pizza costs $4.

Answer:

Please check the explanation.

Step-by-step explanation:

Given the function

f(x) = (x-5)²+1

put x = 2

f(2) = (2-5)²+1 = (-3)²+1 = 9+1 = 10

put x = 3

f(3) = (3-5)²+1 = (-2)²+1 = 4+1 = 5

put x = 4

f(4) = (4-5)²+1 = (-1)²+1 = 1+1 = 2

put x = 5

f(5) = (5-5)²+1 = (0)²+1 = 0 + 1 = 1

put x = 6

f(5) = (6-5)²+1 = (1)²+1 = 1 + 1 = 2

Thus, the table wil be completed as:

x           2         3       4         5        6

f(x)         10        5       2         1        2

The price per T-shirt should be at least $15 to achieve a profit of $250.

To calculate the price per T-shirt that will yield a profit of at least $250, we need to consider the cost of production, the desired profit, and the number of shirts to be sold.

Given that the cost to make each T-shirt is $10, and we want to sell 50 shirts, the total cost of production would be 10 * 50 = $500.

Now, let's calculate the minimum revenue needed to achieve a profit of $250. We add the desired profit to the total cost of production: $500 + $250 = $750.

Finally, to determine the price per T-shirt, we divide the total revenue by the number of shirts: $750 ÷ 50 = $15.

Therefore, to make a profit of at least $250, the price per T-shirt should be set at $15.

By selling each T-shirt for $15, the total revenue would be $15 * 50 = $750. From this revenue, we subtract the total production cost of $500 to calculate the profit, which amounts to $750 - $500 = $250. Thus, by charging $15 per T-shirt, the desired profit of $250 is achieved.

The value of x for which (f - g)(x) = 0 is x = 12.

To find the value of x for which (f - g)(x) = 0, we need to subtract g(x) from f(x) and set the resulting expression equal to zero. Let's perform the subtraction:

(f - g)(x) = f(x) - g(x)

= (16x - 30) - (14x - 6)

= 16x - 30 - 14x + 6

= 2x - 24

Now, we can set the expression equal to zero and solve for x:

2x - 24 = 0

Adding 24 to both sides:

2x = 24

Dividing both sides by 2:

x = 12

Therefore, the value of x for which (f - g)(x) = 0 is x = 12.

Summarizing, representing, and interpreting data on a single count or measurement variable involves using statistical techniques like calculating mean and standard deviation, fitting to a normal distribution, and using specialized tools to estimate areas under the normal curve. However, not all data sets follow a normal distribution, and alternative techniques may be more suitable.

To summarize, represent, and interpret data on a single count or measurement variable, you can use various statistical techniques. One common approach is to calculate the mean and standard deviation of a data set. The mean represents the average value of the data, while the standard deviation measures the variability or spread around the mean.

To fit the data set to a normal distribution, you can use the mean and standard deviation to determine the parameters of the distribution. The normal distribution, also known as the bell curve, is characterized by its symmetric shape and specific mean and standard deviation values. By fitting the data to a normal distribution, you can make inferences and estimate population percentages.

However, it's important to recognize that not all data sets are appropriate for this procedure. Some data sets may not follow a normal distribution, which could lead to inaccurate results. In such cases, alternative statistical techniques may be more suitable.

To estimate areas under the normal curve, you can use calculators, spreadsheets, and tables specifically designed for this purpose. These tools allow you to input the mean, standard deviation, and desired range of values to calculate the area under the curve. This can be useful for estimating probabilities or making predictions based on the normal distribution.

Overall, summarizing, representing, and interpreting data on a single count or measurement variable involves understanding the mean and standard deviation, fitting the data to a normal distribution when appropriate, and using specialized tools to estimate areas under the normal curve.

So, the cell phone tower is 17 feet tall.

To find the height of the cell phone tower, we can use the concept of similar triangles. Since the post and the tower are both vertical, and their shadows are cast on the ground, the angles are the same for both.
First, let's convert the measurements to the same unit. We will use inches:
1 foot = 12 inches, so 2 feet = 24 inches.
Now, we can set up a proportion with the post and its shadow as one pair of corresponding sides and the tower and its shadow as the other pair:
(height of post)/(length of post's shadow) = (height of tower)/(length of tower's shadow)
24 inches / 14 inches = (height of tower) / 119 feet
To solve for the height of the tower, we can cross-multiply:
24 * 119 = 14 * (height of tower)
2856 inches = 14 * (height of tower)
Now, divide both sides by 14:
height of tower = 2856 inches / 14 = 204 inches

Answer:

x√5 = x square root 5

The integral ∫∫ r √4 −x2−y2da where r = {(x, y) : x2 y2≤ 4, x ≥ 0} conversion to polar coordinates the value of the integral is (4/3)π.

To convert the integral to polar coordinates, we need to express the limits of integration in terms of the polar coordinates.

Recall that in polar coordinates, x = r cosθ and y = r sinθ, where r is the radial distance from the origin and θ is the angle measured counterclockwise from the positive x-axis to the line connecting the origin to the point (x, y).

In this case, the region r is defined by \(x^2 + y^2\) ≤ 4 and x ≥ 0. In polar coordinates, this corresponds to the region 0 ≤ r ≤ 2 and 0 ≤ θ ≤ π/2. To see why, note that x ≥ 0 implies 0 ≤ θ ≤ π/2, and \(x^2 + y^2 = r^2\), so r ≤ √4 = 2.

So we have:

∫∫ r √4 −x2−y2da = ∫(θ=0 to π/2) ∫(r=0 to 2) r√(4-\(r^2\)) dr dθ

To evaluate this integral, we can use the substitution u = 4 - \(r^2\), du = -2r dr, which gives:

∫∫ r √4 −x2−y2da = ∫(θ=0 to π/2) ∫(u=4 to 0) -1/2 √u du dθ

Now we can evaluate the inner integral:

∫(u=4 to 0) -1/2 √u du = [-1/3 u^(3/2)](u=4 to 0) = (1/3)(8 - 0) = 8/3

Substituting this back into the original integral, we have:

∫∫ r √4 −x2−y2da = ∫(θ=0 to π/2) (8/3) dθ = (8/3) (π/2 - 0) = (4/3)π

Therefore, the value of the integral is (4/3)π.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

Line p passes through points (-2, 5) and (3, 8).
This means,

Slope = (8 - 5) / (3 + 2) = 3/4

m = 3/4

And,

Consider (-2, 5) = (x, y)

5 = (3/4) x -2 + c

5 = -3/2 + c

c = 5 + 3/2

c = 13/2

So,

y = (3/4)x + 13/2

Line q passes through the points (-1, 4) and (4, 7).

Slope = (7 - 4) / (4 + 1) = 3/5

m = 3/5

To find:

The equation of the axis of symmetry for the given function.

Solution:

If a quadratic function is \(f(x)=ax^2+bx+c\), then the equation of the axis of symmetry is:

\(x=-\dfrac{b}{2a}\)        ...(i)

We have,

\(H(x)=-x^2+10x-11\)

Here, \(a=-1,b=10,c=-11\). So, the equation of axis of symmetry by using (i), is

\(x=-\dfrac{10}{2(-1)}\)

\(x=-\dfrac{10}{-2}\)

\(x=5\)

The interpretation of h(2) = 0.40 in the context of the given function is that, two seconds after the football is kicked, its height is 0.40 meters.

The interpretation of the equation h(2) = 0.40 in the given context is that the football reaches a height of 0.40 meters, approximately 2 seconds after it is kicked. This equation represents the relationship between time and height, with h(t) denoting the height of the football at time t.

Since the input value is 2, it implies that 2 seconds have passed since the football was kicked. The output value, 0.40, represents the height of the football at that specific time. This interpretation assumes that the height is measured from the ground or the initial position of the football.

It is important to note that the equation does not provide information about the maximum height the football reaches. To determine the maximum height, you would need additional information, such as the form of the function or other data points. The given equation simply gives the height of the football at a specific time, in this case, 2 seconds after it was kicked.

According to the statement the distance from the plane to the top of the larger sphere is 3 + 2 = 5 units.

The distance from the plane to the top of the larger sphere can be found by considering the arrangement of the spheres.

We have three smaller spheres of radius 1 that are mutually tangent to each other and the plane.

On top of them, there is a larger sphere of radius 2.
Let's denote the distance from the plane to the center of the larger sphere as h.

Since the spheres are tangent to each other, the distance from the plane to the top of the larger sphere will be equal to the sum of the radii of the smaller spheres (3 x 1 = 3) plus the radius of the larger sphere (2).
Therefore, the distance from the plane to the top of the larger sphere is 3 + 2 = 5 units.

The quadratic equation in its standard form is ax2 + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term. The first condition for an equation to be a quadratic equation is the coefficient of x2 is a non-zero term(a ≠ 0). For writing a quadratic equation in standard form, the x2 term is written first, followed by the x term, and finally, the constant term is written. The numeric values of a, b, c are generally not written as fractions or decimals but are written as integral values.

Let the width of the two paths be x.

Thus, the total area covered by the paths is = (30×x) + (40×x) - x²

The total area covered by the paths is 325 m².

Equate both of them.

⇒ (30×x) + (40×x) - x² = 325

⇒ 30x + 40x  - x² = 325

⇒ x² -70x + 325 = 0

Solving the above equation, we get

Given that the equation of the line in the diagram is `y = 5 - x`. The line cuts the y-axis at P. So, the coordinates of point P are (0,5) and the gradient of the line is `-1`.

The equation of the line can be written as `y = -1x + 5`.Therefore, the y-intercept of the line is 5. Therefore, the coordinates of point P are (0,5).

To find the gradient of the line, we have to write the equation of the line in the form of `y = mx + c`.

We can rewrite `y = -1x + 5` as `y = (-1)x + 5`.From the above form of the equation, we can see that the gradient `m` is `-1`.Therefore, the gradient of line 1 is `-1`.Hence, the required answer is: Coordinates of point P is `(0,5)`.The gradient of the line is `-1`.

a) To find the first three elements of the sequence defined by an = n^2 - 3n + 2, we simply substitute n = 0, 1, 2 into the expression for an and simplify: a0 = 2, a1 = 0, a2 = 0.

b) To show that the sequence satisfies the recurrence relation an = 2an-2 - an-2 + 2 for every n >= 2, we can use mathematical induction. Assume the relation holds for some arbitrary k >= 2. Then we can show that it also holds for k+1 by substituting k+1 into the expression and using the fact that an = (k+1)^2 - 3(k+1) + 2 = k^2 - k + 2 + 2k. After simplification, we arrive at the expression for ak+1 in terms of ak and ak-2, showing that the relation holds for k+1.

a) To find the first three elements of the sequence, we simply substitute n = 0, 1, 2 into the expression for an and simplify:

a0 = (0)^2 - 3(0) + 2 = 2

a1 = (1)^2 - 3(1) + 2 = 0

a2 = (2)^2 - 3(2) + 2 = 0

Therefore, the first three elements of the sequence are 2, 0, 0.

b) To show that the sequence satisfies the recurrence relation an = 2an-2 - an-2 + 2 for every n >= 2, we need to show that the expression for an can be written in terms of the previous two terms of the sequence, a(n-2) and a(n-1), using the given recurrence relation.

We can write:

an = n^2 - 3n + 2

  = (n-2)^2 - 3(n-2) + 2 + 2(n-2)

  = (n-2)^2 - 3(n-2) + 2n

Next, we can substitute n-2 for n in the expression for a(n-2) to get:

a(n-2) = (n-2)^2 - 3(n-2) + 2

Finally, we can substitute n-1 for n in the expression for a(n-1) to get:

a(n-1) = (n-1)^2 - 3(n-1) + 2

Now, we can use these expressions to write an in terms of a(n-2) and a(n-1) as follows:

an = (n-2)^2 - 3(n-2) + 2n

  = a(n-2) + 2(n-1) - (n-1)^2 + 3(n-1)

  = 2a(n-2) - a(n-1) + 2

Therefore, we have shown that the sequence satisfies the recurrence relation an = 2an-2 - an-2 + 2 for every n >= 2.
