Quadratic equation :The maximum height reached by Alonzo's ball will be 9m.

What is a quadratic equation?

The equation whose highest degree of the variable used in the equation is 2 and has 2 roots, is called quadratic equation.

Here the quadratic equation of the path of Chase's ball is given by y = - 4x²+ 5x+ 7
To compare the height of both paths followed by the ball
we have to first calculate the height of the path of Chase's ball.
the path of Chase's ball is f(x)=-4x²+ 5x+ 7
The function will have the highest value when f'(x) will be 0.
f'(x)=-8x+5
f'(x)=0
⇒-8x+5=0
⇒-8x=-5
⇒x=5/8
at x=5/8, function value is
f(x)=-4x²+ 5x+ 7
=-4(5/8)²+ 5(5/8)+ 7
=-4(25/64)+(25/8)+7
=(-25/16)+25/8+7
=8.5625
There maximum value of f(x) is 8.5625.
The maximum height reached by Chase's ball will be 8.5625m.
From the graph of the path of Alonzo's ball, it is clear that
The maximum height reached by Alonzo's ball will be 9m.
As 8.5625m < 9m
Alonzo's baseball will reach greater height.

Step-by-step explanation:

The length of the arc opposite a central angle that measures 46 degrees is 2.72 cm.

What is circle?

The measurement of the circle's boundaries is called as the circumference or perimeter of the circle. whereas the circumference of a circle determines the space it occupies. The circumference of a circle is its length when it is opened up and drawn as a straight line. Units like cm or unit m are typically used to measure it. The circle's radius is considered while calculating the circumference of the circle using the formula. As a result, in order to calculate the circle's perimeter, we must know the radius or diameter value.

in a circle of radius 3.4 cm

central angle that measures 46 degrees

length of arc = (46/360) * 2π*3.4

=2.72cm

Hence the length of the arc opposite a central angle that measures 46 degrees is 2.72 cm

Step-by-step explanation:

Given

See attachment for matrices

(a)

\(D = \left[\begin{array}{cc}\cos\theta &\sin\theta\\ -\sin\theta& \cos\theta\\\end{array}\right]\)

The determinant of the matrix is:

\(|D |= (\cos\theta * \cos\theta - \sin\theta *- \sin\theta)\)

\(|D | = \cos^2\theta + \sin^2\theta\)

Using trigonometry ratio, we have:

\(|D | = 1\)

(b)

\(\left[\begin{array}{ccc}2&0\\0&2\end{array}\right]\)

The determinant of the matrix is:

\(|D| = 2 * 2 - 0 * 0\)

\(|D| = 4 - 0\)

\(|D| = 4\)

(c)

\(\left[\begin{array}{ccc}0&i\\-i&0\end{array}\right]\)

The determinant of the matrix is:

\(|D| = 0 * 0 -(-i * i)\)

\(|D| = 0 +i^2\)

\(|D| = i^2\)

In complex numbers

\(i^2 = -1\)

So:

\(|D| = -1\)

Answer:

x = -9

Step-by-step explanation:

If we simplify the equation and replace the numbers they give us with the letters, our equation would look like this:

8 = 3x + 2(7)

So, we need to simplify this down so we only have x = ?.

So, we use PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition Subtraction). PEMDAS it just a good example to help you remember how to simplify first. So, we do have a parenthese, so we need to do that first:

8 = 3x + 14

Next, we have in PEMDAS addition:

8 = 17x

Now, finally we simplify by subtracting 17 on both sides so we can have x by itself:

-9 = x

Answer:

0.17 per ounce

Step-by-step explanation:

To find the price per ounce, divide the price by the number of ounces.

price/ number of ounces

A 2 pound bag costs $5.44. We need to find out how many ounces are in 2 pounds.

Each pound has 16 punches. Therefore, 2 pounds will have 32 ounces (16 ounces * 2 pounds=32 ounces).

Now we can find the price per ounce by dividing the price by the number of ounces.

price/ounces

We know the bag is 2 pounds, which is equal to 32 ounces. We also know the bag costs $5.44

price= $5.44

ounces= 32 ounces

$5.44/ 32 ounces

$0.17 / ounces

The asparagus costs 0.17 per ounce.

Higher mean absolute deviation is an example of a measure of variability and range. It give us some information about how spread out the data in a data set is. When used together with measures of center like the mean and median, they can give us a useful overview of the data set.

For an example,

A chef wants to hire someone to work in his kitchen. There are two candidates: Sally and Nader. To test their abilities, he times how long it takes them to make each of four meals and records the data in two tables.

He decides to calculate the mean time it took each candidate to make the four meals; he is planning to hire the candidate with the lower (quicker) mean time.

The mean time it takes Sally to make a meal is

= 3+5+7+9 / 4

=24/6

= 6 minutes

The mean time it takes Nader to make a meal is

= 5+6+5+8 / 4

=24/4

= 6 minutes

After having mean times same he doesn't classify which one is best he used their statical graphs.

For Sally, the mean absolute deviation of her times is the mean of the distances,

=4+1+2+3 / 4

=2.5

For Nader, the mean absolute deviation of his times is

= 1+0+1+2 / 4

=1

The chef sees that the mean absolute deviation of Nader’s times is lower than the mean absolute deviation of Sally’s times. This shows that Nader is more consistent in his cooking times and agrees with what we observed from the bar graphs.

Which means that the higher mean absolute deviation occurs less consistency in the mean absolute deviation.

The total number of ways to distribute a total inventory of twenty batteries among the six different types is 10 x 120,332,228 = 1,203,322,280.

To determine how many ways a total inventory of twenty batteries can be distributed among the six different types, we need to use the concept of combinations. We know that there are seven different types of batteries, but we are given that there are only ten a7b batteries and at least twenty of each of the other types. This means that the maximum number of batteries that can be used from the other six types is 20 x 6 = 120.

So, to distribute a total of twenty batteries among the six types, we need to consider the number of a7b batteries and the number of batteries from the other six types. Since we are given that there are only ten a7b batteries, we can distribute them in 10 different ways among the six types.

For the other six types, we have a maximum of 120 batteries to use. To distribute 20 batteries among these six types, we can use the formula for combinations, which is nCr = n! / r!(n-r)!. In this case, we have 120 batteries to choose from, and we want to choose 20 batteries, so the formula becomes 120C20 = 120! / 20!(120-20)! = 120,332,228 ways.

Therefore, the total number of ways to distribute a total inventory of twenty batteries among the six different types is 10 x 120,332,228 = 1,203,322,280.

According to this research, options B and D appear to be the most slope plausible explanations for the data. However, without the real data, determining which equation is the best model is impossible.

The slope of a line indicates how steep it is. The gradient's mathematical equation is known as "gradient overflow" (the change in y divided by the change in x). The slope is defined as the ratio of the vertical change (rise) between two places to the horizontal change (run). The slope-intercept form of an equation is used to express a straight line's equation, which is written as y = mx + b. The y-intercept is found where the slope of the line is m, b is b, and (0, b). For example, consider the slope and y-intercept of the equation y = 3x - 7.The slope of the line is m. b is b at the y-intercept, and (0, b).  

It is impossible to establish which equation is the best model of the data without the actual data. However, we may analyse each possibility based only on the facts provided:

A. y= 2.2 - (1.1%): This equation appears to contain a constant term and a negative slope, making it unsuitable for predicting plant height over time.

B. y= 0.5x + 1.8: The positive slope of this equation indicates that the plant's height rises with time. The constant term of 1.8 might represent the plant's beginning height, while the coefficient of 0.5 could reflect the plant's growth rate.

C. y= 2.0 • (1.4%): This equation appears to contain a constant term and a positive slope, but the percentage term is not obvious how it links to the data.

D. y = 0.7 x + 2.1: This equation, like option B, has a positive slope and a constant term. The coefficient of 0.7 might reflect the plant's growth rate, while the constant term of 2.1 could represent the plant's original height.

According to this research, options B and D appear to be the most plausible explanations for the data. However, without the real data, determining which equation is the best model is impossible.

If two dice are rolled, then the chances that the sum of the spots is 6 is option (b) 5/36

To calculate the probability of rolling a sum of 6 with two dice, we need to count the number of possible outcomes that add up to 6 and divide that by the total number of possible outcomes when rolling two dice.

There are five possible outcomes that add up to 6:

1 and 5

2 and 4

3 and 3

4 and 2

5 and 1

And there are a total of 36 possible outcomes when rolling two dice, since each die has 6 possible outcomes and there are 6 × 6 = 36 possible pairs of outcomes.

Therefore, the probability of rolling a sum of 6 with two dice is:

5/36

Therefore, the correct option is (b) 5/36.
