The maximum value or minimum value of a quadratic function are located at its vertex, which is shaped like a U. The quadratic function's axis of symmetry crosses the function (a parabola) at its vertex.

This graph's opening side plus vertex determine the quadratic function's range. To ascertain the quadratic function's range, locate the lowest and highest f(x) values on the function graph.

Standard form for quadratic function:

f(x) = ax² + bx + c,

In which, a, b, and c -  real numbers and  a ≠ 0.

Given function for the which explain the height of ball with time:

f(x) = -6x² + 36x + 0.23

f(x) is the height of ball taken from ground.

x is the time in seconds.

Draw the graph of the function using the graphing tool.

The diagram is attached.

The vertex of the graph lies at (3, 54.23).

x - 3 seconds

f(x) = 54.23 ft

So, time taken by ball to reach at height of 54.23 ft is 3 seconds.

Total time to reach the ball at ground = 2*3 =  6 seconds

Thus, the total time to reach the ball at ground after being kicked is 6 seconds.

Step-by-step explanation:

The measure of angle K is 48, the measure of angle m is 90. From there you have 138 degrees. A triangle is 180 degrees. You subtract 138 from 180.

The measure of angle J from the given triangle JKL is 42°.

Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.

In the given triangle JKL and m∠JKM = 48°.

We know that, angle bisector in isosceles triangle is perpendicular bisector of base.

In triangle JKM,

m∠J+m∠JKM+m∠KMJ=180°

Answer:

4 t shirts.

Step-by-step explanation:

Given that money available with Sam = $150

Price for pants = $90

Price of each t shirt = $12.50

To find:

How many t shirts can he expect to purchase?

Solution:

Price for 2 pants = $180 which is more than $150.

Therefore, he can not buy more than 1 pants.

The remaining amount after buying pants = $150 - $90 = $60

This amount will be used for buying t-shirts.

Number of t-shirts that can be bought:

\(\dfrac{60}{12.5} \approx 4.8\)

But answer in decimal points for number of t shirts is not possible and he does not have more money.

It means, he can buy at most 4 t-shirts.

Answer:

k=-570

Step-by-step explanation:

P(x) = kx^3+23x^2+71x+30

If 2x-1 is a factor of p(x)

Then,

2x-1 =0

2x=1

x=1/2 and at this value, p(x) =0

Substitute x = 1/2 for x in p(x)

p(1/2) = k(1/2)^3 + 23(1/2)^2;+71(1/2)+30

k(1/8)+23/4 +71/2+30=0

k/8= -23/4 -71/2-30

k/8 = -285/4

k= -(285*8)/4

k=-570

Thus, the polynomial p(x) = -570x^3 +23x^2 +71x +30

Factorization of p(x)

Step-by-step explanation:

The surface area of the table tennis ball will be around 1256.64 mm².

A sphere is a 3D geometrical object which has a radius and becomes a point that revolves around a fixed point called the center.

A sphere has surface area and volume based upon the radius of the sphere.

For example, if you have a sphere of radius r then its surface area will be 4πr² and volume will be (4/3)πr³.

The table tennis ball is the form of a sphere.

Given that,

The diameter of a table tennis ball is 20

Radius(r) = 20/2 = 10 mm

Surface area of an sphere = 4πr²

So,

Area = 4π(10)² = 1256.64 mm².

Hence "The surface area of the table tennis ball will be around 1256.64 mm²".

The pebbles cover an area of 147 sq ft. We can use the Pythagorean theorem to find the solution.

Let's call the length of the third side of the triangle "x".

Since the two triangles are equal in size, and they share two sides with the square, we can use the Pythagorean theorem to find x.

a² + b² = c²

7² + 7² = c²

49 + 49 = c²

98 = c²

c = sqrt(98)

c = 7sqrt(2)

So each triangle has a base of 7ft and a height of 7sqrt(2)ft.

Area of each triangle = (base * height) / 2 = (7 * 7sqrt(2)) / 2 = 24.5 sq ft

Since there are two triangles, the total area of the grass is 24.5 sq ft * 2 = 49 sq ft

The square has an area of 14ft * 14ft = 196 sq ft

The pebbles cover an area of 196 sq ft - 49 sq ft = 147 sq ft.

The probability that the events do not occur is 0.6778`.

The probability that the events do not occur is given by `P(Ac)=1-P(A)` and `P(Bc)=1-P(B)`.

The given probabilities are `P(A)=0.2272` and `P(B)=0.4506`.

Using the formula `P(A∪B)=P(A)+P(B)-P(A∩B)`, we have `P(A∩B) = P(A) + P(B) - P(A∪B)`

Using the fact that the two events are mutually exclusive, we get `P(A∩B) = 0`.

Thus, `P(A∪B) = P(A) + P(B) = 0.2272 + 0.4506 = 0.6778`.

The probability that either A or B but not both occurs is given by `P(AΔB) = P(A∪B) - P(A∩B) = 0.6778 - 0 = 0.6778`.

Hence, the required probability is `P(AΔB) = 0.6778`.

The major shortcoming of the general linear probability model y = β0 + β1x1 + β2x2 + … + βkxk + ε, is that the predicted values of y can be sometimes greater than 1 or less than 0.

The linear probability model does not take into account the fact that probabilities are bounded between 0 and 1. As a result, the predicted values of y can sometimes fall outside of this range, which is not meaningful or interpretable in terms of probability. To address this issue, alternative models such as logistic regression or probit regression can be used, which are specifically designed to model probabilities and ensure that predicted values fall within the appropriate range. These models use non-linear functions to map the values of the independent variables to probabilities, thereby avoiding the problem of predicted values falling outside the valid range.

Therefore,the major shortcoming of the general linear probability model y = β0 + β1x1 + β2x2 + … + βkxk + ε, is that the predicted values of y can be sometimes greater than 1 or less than 0.

It is false that sampling distribution is normal only if the population is normal.

According to the central limit theorem, when sample sizes are sufficiently large (typically n ≥ 30), the sampling distribution of the sample mean tends to approximate a normal distribution regardless of the population's underlying distribution.

This is true even if the population itself is not normally distributed. However, for small sample sizes, the shape of the population distribution can have a greater influence on the shape of the sampling distribution.

John's savings amount as a function of time is S(t) = $24,000 / 25. Initially, he needs to save $24,000 for a new car. After the first month, he has saved $1,000. The savings amount is directly proportional to the time elapsed. The constant of proportionality is 1/24. Thus, John's savings amount can be determined based on the remaining amount he needs to save.

John's savings amount can be represented as a function of time and is proportional to the amount he still needs to save. Let's denote the amount John needs to save as N(t) at time t, and his savings amount as S(t) at time t. Initially, John needs to save $24,000, so we have N(0) = $24,000.

We know that John has saved $1,000 after the first month, which means S(1) = $1,000. Since his savings amount is proportional to the amount he still needs to save, we can write the proportionality as:

S(t) = k * N(t)

where k is a constant of proportionality.

We need to find the value of k to determine John's savings amount at any given time.

Using the initial values, we can substitute t = 0 and t = 1 into the equation above:

S(0) = k * N(0)  =>  $1,000 = k * $24,000  =>  k = 1/24

Now we have the value of k, and we can write John's savings amount as a function of time:

S(t) = (1/24) * N(t)

Since John's savings amount is proportional to the amount he still needs to save, we can express the amount he still needs to save at time t as:

N(t) = $24,000 - S(t)

Substituting the expression for N(t) into the equation for S(t), we get:

S(t) = (1/24) * ($24,000 - S(t))

Simplifying the equation, we have:

24S(t) = $24,000 - S(t)

25S(t) = $24,000

S(t) = $24,000 / 25

Therefore, John's savings amount at any given time t is S(t) = $24,000 / 25.
