5. Below is a model of the infield of a baseballstadium. How long is each side of the infield?oth a perfectquare rootnumbers?A= 81 in.?

Answers

We have that the area of the infield is 81 in2.

This area is a square, which means it has equal sides, and its area is:

[tex]\text{Area}=side^2[/tex]

If the area of the square is 81 in2, we have that:

Answers

If A=[-9,0,3,-1] b=[0,4,-6,2] , so the order of matrix A+B is 4x1(4 rows and 1 column).

What is matrix ?

Matrix, a set of number arranged in rows and column so as to form a rectangular array. The number are called the elements, or entries, of the matrix .

What does the matrix serve as?

Both data and mathematical equations can be represented by the numbers in a matrix. Multiplying matrices can provide quick but accurate approximations of considerably more complex calculations in many time-sensitive engineering applications.

The elements of the matrix are nothing but the entries of the matrix.

So according, To the question we are adding matrix A which is 4 rows and 1 column to matrix B which is also of 4 rows and one column obtaining a third matrix that has also 4 rows and 1 column :

[-9,0,3,-1]+[0,4,-6,2]=[-9,4,-3,1]

The resultant A+B is also of 4 rows and 1 column

Hence the order of matrix A+B is 4x1 (4 rows and 1 column)

Answers

The distance that the person bike over the past 5 weeks is 7284 feet.

How to illustrate the expression?

Distance is the sum of an object's movements, regardless of direction. Regardless of an object's starting or ending position, distance can be defined as the amount of ground it has covered. Distance is a measurement of how far apart two things or points are, either numerically or occasionally qualitatively.

From the information, the forest trail is 607 feet long and a person biked from one end to the other and back again 6 times in the past 5 weeks.

Therefore, the distance that the person covered will be:

= 2 × 6 × 607

2x+5+7x = 8x-11 solve for x

Answers

Answer:

Step-by-step explanation:

2x + 5 + 7x = 8x -11 Combine like terms

9x + 5 = 8x -11 Subtract 8x from both sides of the equation

x + 5 = -11 Subtract 5 from both sides of the equation.

x= -16

Answer: -16

Step-by-step explanation:

2x+5+7x = 8x-11 simplifies into 9x+5 = 8x -11.

Move 8x to the other side - put like terms together : 9x-8x+5 = -11

Which is simplified into x+5 = -11

Move 5 to the other side to isolate x: x = -11 -5

Combine -11 and -5

x = -16

us the data set to choose the two measures that are equivlent 4, 5, 6, 7, 8

Answers

The mean and median of the data are equivalent and the value is 6.

The mean (average) of a data set can be calculated by adding up all the numbers in the collection and dividing by the total number of values in the set.

When a data set is sorted from least to greatest, the median is the middle. The value that pops up most frequently in a data set is its mode.Between the lowest and highest value is the range. You subtract the lowest value from the greatest value to calculate it.The exact midpoint between the lowest and highest values in a set of data is the midway value. Finding the middle requires adding the smallest and greatest values together, then dividing the result by two.

Let us find the mean of the data set :

mean = (4 + 5 + 6 + 7 + 8) ÷ 5 = 30÷ 5 = 6

Median = 6 middle value.

Therefore the mean and median are equivalent.

Why is 0.68 a rational number?

0.68 can be regarded as a rational number because it is a finite number that is also a fraction of two whole integers. In this case, the integers are 68 and 10. Another feature by which rational numbers are known is the fact that they are repeating in nature.

However, it is important to note that the decimal here is terminating in nature because it has a finite number of zeros behind the number 8. So, the reason for selecting 0.68 as a rational number is that it terminates.

When 12 is subtracted from the square of a number, the result is 4 times the number. Find the negative solution.

Answers

When 12 is subtracted from the square of a number and the result is 4 times the number, then the negative solution is -2

Consider the number as x

Square of the number = [tex]x^{2}[/tex]

12 subtracted from the square of a number = [tex]x^{2} -12[/tex]

4 times the number = 4x

Then the equation will be [tex]x^{2} -12=4x[/tex]

Rearrange the terms and it will become a quadratic equation

[tex]x^{2} -4x-12=0[/tex]

Split the middle term and solve the equation

[tex]x^{2} +2x-6x-12=0[/tex]

Take common terms

x(x+2)-6(x+2) = 0

Take common term outside

(x-6)(x+2) = 0

Therefore

x = 6, -2

The negative solution is -2

Hence, when 12 is subtracted from the square of a number and the result is 4 times the number, then the negative solution is -2

The hang time is calculated to be a. 1.5 seconds if the vertical component of velocity for the projectile is 7.3 meters/second.

The formula for the height of the projectile can be used to calculate the hang time as follows;

h = ut - 0.5at²

here;

h is the height of the projectile

u is the velocity = 7.3 m/s

a is the acceleration due to gravity

The standard value of acceleration due to gravity is equal to 9.81 m/s²

The height will be zero both the times when t=0 and when the journey has been completed

Now adding these values to the formula;

h = ut - 0.5at²

0 = 7.3t - 0.5(9.81)t²

Solving for t;

4.905t² = 7.3t

4.905t² / t = 7.3

4.905t = 7.3

t = 7.3 / 4.905

t = 1.49 ≈ 1.5
