Sure, I can help you with that! First, we know that the vertex form of a quadratic function is: f(x) = a(x - h)^2 + k where (h, k) is the vertex of the parabola. So we can plug in the values we have: f(x) = a(x - 2)^2 + 1 Now we just need to find the value of "a". To do that, we can use the fact that the function goes through the point (4, 5). So we can plug in those values: 5 = a(4 - 2)^2 + 1 Simplifying, we get: 5 = 4a + 1 4a = 4 a = 1 So now we know that the quadratic function is: f(x) = (

a. 90 degree clockwise rotation about the origin (x, y) → (y , -x). b. 180 degree clockwise rotation about the origin (x, y) → (-x, - y). c. 270 degree clockwise rotation about the origin (x, y) → (-y, x).

The transformation, or f: X X, is the name given to a function, f, that maps to itself. After the transformation, the pre-image X becomes the picture X. Any operation, or a combination of operations, such as translation, rotation, reflection, and dilation, can be used in this transformation. A function can be moved in one way or another using translation, rotation, reflection, and dilation. A function can also be scaled using rotation around a point. Two-dimensional mathematical figures move about a coordinate plane according to transformations.

The mapping statement for each rotation in the is given as:

a. 90 degree clockwise rotation about the origin (x, y) → (y , -x)

To estimate the number of students out of the next 10 who will support Julian, we can use the proportion of students who have supported Julian so far.

The total number of students who have been surveyed is:

15 + 9 + 16 + 10 = 50

Out of these 50 students, 15 have supported Julian. Therefore, the proportion of students who have supported Julian so far is:

15/50 = 0.3

To estimate how many of the next 10 students surveyed will support Julian, we can multiply the proportion of students who have supported Julian so far by 10:

0.3 x 10 = 3

Therefore, we can estimate that out of the next 10 students surveyed, about 3 will support Julian.

Answer:

Yes, the triangle with side lengths 6, 8, and 10 is a right triangle.

Explaination:

We can use the Pythagorean theorem to check if a triangle is a right triangle or not. According to the Pythagorean theorem, in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side (the hypotenuse). In other words:

a^2 + b^2 = c^2

where a and b are the lengths of the two shorter sides, and c is the length of the longest side (the hypotenuse).

In this case, the two shorter sides are 6 and 8, and the longest side (the hypotenuse) is 10. So we can plug these values into the equation above:

6^2 + 8^2 = 10^2

Simplifying:

36 + 64 = 100

100 = 100

Since the equation is true, this means that the triangle satisfies the Pythagorean theorem, and therefore it is a right triangle.

The area of the triangular base of the prism is 9.5 unit².

What is an area?

To find the area of the triangular base, we need to use the formula for the volume of a triangular prism:

V = (1/2)×b×h×H

Where b is the length of the base of the triangle, h is the height of the triangle, and H is the height of the prism.

We know that the volume of the prism is 27.36 unit³ and the height of the prism is 2.88 units. So we can plug these values into the formula:

27.36 = 1/2×b×h×2.88

Simplifying this equation, we get:

b×h = 19

We don't know the values of b and h separately, but we can use the fact that the area of a triangle is equal to (1/2)×b×h. So we can rewrite the equation as:

2 × (Area of triangular base) = 19

Dividing both sides by 2, we get:

Area of triangular base = 9.5 units²

Therefore, the area of the triangular base of the prism is 9.5 unit².

Step-by-step explanation:

Using the inverse variation formula, p × q = k, where k is a constant, we can solve for q when p is equal to 2, given that p and q vary inversely and p is 24 when q is 23 when p is equal to 2, q is equal to 276.

When two variables vary inversely, as one variable increases, the other variable decreases proportionally, and vice versa. In this problem, p and q vary inversely, which means that if we multiply p by some constant, we need to divide q by the same constant to maintain the inverse variation.

First, we need to find the value of k using the given information:

p × q = k

24 × 23 = k

k = 552

Now that we have the value of k, we can use it to solve for q when p is equal to 2:

p × q = k

2 × q = 552

q = 276

To find the value of the 30th percentile,

We need to sort the data set in ascending order first,

1, 2, 3, 3, 4, 5, 6, 7, 9, 9, 12, 13, 14, 15, 15, 16, 17, 17, 18, 20

The 30th percentile is the value below which 30% of the data falls.

To find this value, we can use the formula,

P = (n / 100) × x

where P is the desired percentile (30th percentile in this case),

n is the total number of data points,

And x is the rank of the value corresponding to the desired percentile.

Here,

The total number of data points n = 20

x = (30 / 100) × 20

Burger Quick is able to estimate their wait time more consistently because it has a smaller IQR (Interquartile Range).

What is an IQR?

The IQR represents the range of the middle 50% of the data, and is a measure of the spread of the data. A smaller IQR indicates that the data is less spread out and more consistent. Therefore, since Burger Quick has a smaller IQR than Super Fast Food, it is able to estimate their wait time more consistently.

It is calculated by finding the difference between the third quartile (Q3) and the first quartile (Q1) of a dataset. The quartiles are values that split the data into four equal parts: Q1 represents the 25th percentile, Q2 (also known as the median) represents the 50th percentile, and Q3 represents the 75th percentile. The IQR therefore represents the range of the middle 50% of the data.

The IQR is a useful measure of variability because it is less sensitive to outliers than the range or standard deviation, which can be skewed by extreme values in the data. The IQR is often used in box plots to show the spread of the data and identify potential outliers.

What is Burger Quick?

Burger Quick is likely a hypothetical or fictional drive-thru restaurant used in a statistical analysis or problem. It was mentioned in a question about box plots and wait times at drive-thru restaurants, and may not actually exist as a real establishment.

To find the minimum value of a quadratic function most efficiently, we would like to see the quadratic function in its vertex form.

The vertex form of a quadratic function is given by:

f(x) = a(x - h)^2 + k

where (h, k) is the vertex of the parabola, and "a" determines the direction and the "stretch" of the parabola.

If a > 0, the parabola opens upwards, and if a < 0, the parabola opens downwards.

The minimum value of the function occurs at the vertex if the parabola opens upwards (a > 0), and the maximum value occurs at the vertex if the parabola opens downwards (a < 0).

In this case, since we're looking for the minimum value, we would want a quadratic function where a > 0. Once we have the vertex form, we can easily identify the vertex (h, k), and the minimum value of the function will be k.

For the given triangle when G is the incenter of ABC the value of DG = 12, FC = 35, BG = 13.41, BF = 6.

The intersection of all three of the triangle's interior angle bisectors is where a triangle's incenter is located. It may be thought of as the intersection of the triangle's internal angle bisectors. Due to the junction point of the central axis being the centre of the triangle's inscribed circle, this point will be equally spaced from each of the triangle's sides.

The centre of a triangle's inscribed circle, which is the biggest circle that can fit within the triangle, is known as the incenter.

Given that, G is the incenter of the triangle.

Thus, EG = GF = DG.

Now, the value of DG is determined using the Pythagoras Theorem:

(37)² = DG² + (35)²

1369 = DG² + 1225

DG = 12

Now, FC = 35.

For, BG we have:
