Step-by-step explanation:

You jumped rope of 1/3 of 3/4 hour.

In math, "of" usually means times.

The dimensions of a basketball court are shown below. Suppose a player throws the ball from a corner to a teammate standing at the center of the court. a. If center court is located at the origin, find the ordered pair that represents the location of the player in the bottom right corner b. find the distance that the ball travels

Answers

The 94 ft. by 50 ft dimensions of the court obtained from a similar question posted online, gives;

a. The ordered pair representing the location of the player in the bottom right corner is (47, -25)

b. The distance traveled by the ball obtained using Pythagorean theorem, is approximately 53.2 feet.

How can Pythagorean theorem be used to find the distance the ball travels?

The possible dimensions of a rectangular court obtained from a similar question posted online are;

Length of the basketball court = 94ft.

Width of the basketball court = 50 ft.

From the question, we have;

Location of the court center = The origin of a coordinate plane

a. The ordered pair that represent the location of a player in the bottom right corner is found as follows;

Let (x, y) represent the coordinates of the bottom right corner of the court, we have;

Horizontal distance from the center of the court (the origin) to the right boundary of the court, x = (94 ft.)/2 = 47 ft.

Vertical distance from the center to bottom of the court, y = (50 ft.)/2 = 25 ft.

Following the convention of points to the right and above the origin being positive, while points below the origin are negative, we have;

The ordered pair (the coordinates of the player) that represents the location of the player in the bottom right corner is therefore;

(x, y) = (47, -25)

b. The distance, d, that the ball travels is given by Pythagorean theorem as follows;

d = √((47 - 0)² + ((-25) - 0)²) = √(2834) ≈ 53.2

The ball travels approximately 53.2 feet.

What is the largest integer?

Integers are whole numbers. An integer is number that is not a fraction and not a decimal. Integers can either be positive, negative or zero. An example of an integer is 100, - 100 and 0.

An even number is a number that is divisible by 2 into two equal halves. An example is 2, 4, 6, 8. Consecutive even integers are whole even numbers that follow each other on the number line. An example is 2, 4, 6, 8.

Then draw a horizontal line until reaching the y axis.

You should arrive at y = -5. This tells us f(-4) = -5

The input x = -4 leads to the output y = -5

The perimeter of a rectangular pool is more than 62 meters, and the width is at least 10 meters less than the length. Which system of inequalities represents the possible length in meters, l, and the possible width in meters, w, of the pool?

w ≤ 10 – l
2l + 2w ≥ 62
w ≤ 10 – l
2l + 2w > 62
w ≤ l – 10
2l + 2w ≥ 62
w ≤ l – 10
2l + 2w > 62

Answers

the system of inequalities that represents the possible length in meters, l, and the possible width in meters, w, of the pool is given as w ≤ l - 10 and 2 l + 2 w > 62.

Let the length of the pool be x.

So, ATQ, the width will be represented by the inequality:

x - 10 ≥ width

w ≤ x - 10

w ≤ l - 10

Also, it is given that, the perimeter of the pool is more than 62 m
So, we get that:

P > 62

Also, we know that:

P = 2 l + 2 w

So, we get that:

2 l + 2 w > 62.

Therefore, the system of inequalities that represents the possible length in meters, l, and the possible width in meters, w, of the pool is given as w ≤ l - 10 and 2 l + 2 w > 62.

2.3p – 10.1 = 6.4p – 4
2.3p – 10.1 = 6.49p – 4
230p – 1010 = 650p – 400 – p
23p – 101 = 65p – 40 – p
2.3p – 14.1 = 6.4p – 4

Answers

The equivalent equation for the given equation is 2.3p - 10.1 =6.49p - 4. Therefore, option B is the correct answer.

Given that, 2.3p – 10.1 = 6.5p – 4 – 0.01p.

We need to find which equations have the same solution as the given equation.

What is an equivalent equation?

Equivalent equations are algebraic equations that have identical solutions or roots. Adding or subtracting the same number or expression to both sides of an equation produces an equivalent equation. Multiplying or dividing both sides of an equation by the same non-zero number produces an equivalent equation.

Now, 2.3p - 10.1 = 6.5p - 4 - 0.01p can be simplified as follows:

To add or subtract terms of algebraic equations group like terms add numerals and keep the variables the same.

That is, 2.3p - 10.1 = (6.5p - 0.01p) - 4  

⇒2.3p - 10.1 =6.49p - 4

The equivalent equation for the given equation is 2.3p - 10.1 =6.49p - 4. Therefore, option B is the correct answer.

Rewrite the following standard form linear equation into slope-intercept form. Write the answer starting with y=

12x-4y=-12

Answers

The equation of the line in the slope-intercept form is given y= 3x + 3 .

The graph of the equation y = mx + c is a line with m as the slope and m and c as the y-intercept. In the slope-intercept representation of the linear equation, the values of m and c are real numbers. A line's slope, expressed in m, indicates how steep it is. A line's gradient is also referred to as its slope occasionally. The y-coordinate of the point where the line's graph meets the y-axis is known as the y-intercept, or c, of a line.

The  equation of the line is given by 12x - 4y = -12 .

This is the standard form of the line.

Now to represent the line in the slope-intercept form we need to write the equation for y in terms of x.

or, 12x-4y=-12

or, -4y = -12x - 12

or, y = (-12x - 12 ) ÷ (-4)

or, y = 3x + 3

Here the slope is 3 and the y-intercept is also 3.

Therefore the slope-intercept form of the line is given by y = 3x + 3

-33 is the value of √x² - y² at x = 3 and y = -6.

The expression given in the question is √x² - y² and we have to find the value of this expression when the value of x is 3 and the value of y is -6.

In order to evaluate √x² - y²  simply put x = 3 and y = -6 and then solve accordingly.

Let's proceed to solve the expression,

√x² - y²

at x = 3 and y = -6. we have

= √3² - (-6)²

= √9-36

= 3-36

= -33

⇒√x² - y² = -33

∴ On solving, √x² - y² for x = 3 and y = -6 we get -33 as its evaluation.

What is an equation of the line that passes through the points (−1,−7) and (−8,0)?

Answers

The equation of the line that passes through the points is y = -x - 8

What is an equation of the line that passes through the points?

The points are given as:

(−1,−7) and (−8,0)

Calculate the slope (m) using

m = (y2 - y1)/(x2 - x1)

So, we have

m = (0 + 7)/(-8 + 1)

This gives

m = -1

The equation of the line that passes through the points is then calculated as

y = m(x - x1) + y1

So, we have

y = -1(x + 8) + 0

This gives

y = -x - 8

Hence, the equation of the line that passes through the points is y = -x - 8
