Data were collected on the distance a baseball will travel when hit by a baseball bat at a certain speed. the speed, s, is measured in miles per hour, and distance, y, is measured in yards. the line of fit is given by Å· = 3.98 53.59s. if the ball travels for a duration of 5 seconds, what is the predicted distance of the ball? 267.95 feet 271.93 feet 283.87 feet 287.85 feet
Answers
By evaluating the linear equation in t = 5 seconds, we will see that the distance traveled is 271.93 feet.
What is the predicted distance of the ball?
Here we know that the line that defines the distance traveled by the ball (y) as a function of time (t) is:
y = 3.98 + 53.59*t
Now we want to predict the distance traveled y the ball if it travels for 5 seconds, so we just need to evaluate the above linear equation in t = 5.
So we will get:
y = 3.98 + 53.59*5 = 271.93
So we conclude that the distance traveled in that time is 271.93 feet.

[tex]d= \frac{ax+by+c}{\sqrt {a^{2}+b^{2}} } \\\\=\frac{1(0)-1(-3)-1}{\sqrt{2} } \\\\=\frac{2}{\sqrt{2} } = \sqrt{2}[/tex]
What is the distance from a point to a line?
The distance between a point and a line in Euclidean geometry is the shortest path between any two points on an infinite straight line. The length of the line segment connecting the point to the closest point on the line, measured perpendicularly to the line, is the distance between them.If the variances of the dependent and independent variables are equal, then Deming regression, a form of linear curve fitting, produces orthogonal regression, in which each data point's degree of fit error is expressed as the angle of the point from the regression line.To learn more about distance from a point to a line, refer:

Find an nth-degree polynomial function with real coefficients satisfying the given conditions. If you are using a graphing utility, use it to graph the function and verify the real zeros and the given function value. N=3; 3 and 2i are zeros; f(-1)=20
Answers
An nth- degree polynomial function with real coefficient for N = 3 ; 3, 2i are zeros ; f(-1) =20 is given by f(x) = (-1)( x³ -3x²+4x -12).
As given in the question,
Number of zeros of the polynomial function N = 3
Real and complex zeros = 3, 2i , -2i
Function value f(-1) = 20
f(x) = k (x-3)(x-2i)(x+2i)
⇒f(x) = k(x-3)(x²-4i²)
⇒f(x) =k(x-3)(x²+4)
⇒f(-1) = k(-1-3)((-1)² +4)
⇒ 20 =k(-4)(5)
⇒k =-1
Now , f(x) = (-1)((x-3)(x²+4)
= (-1)(x³ -3x²+4x -12)
Therefore, nth- degree polynomial function with real coefficient for N = 3 ; 3, 2i are zeros ; f(-1) =20 is given by f(x) = (-1)( x³ -3x²+4x -12).

Answers
By applying the distributive property of multiplication, the students that are correct in their approach to solving the problem are: Nico, Raj and Sandra.
How to solve the given equation?In order to open the bracket and isolate the variable x, we would first of all multiply both sides by 5/2 as follows:
2/5(5 + x) = 8
Multiplying both sides by 5/2, we have:
5/2 × 2/5(5 + x) = 8 × 5/2
5 + x = 40/2
5 + x = 20
Subtracting 5 from both sides, we have:
5 + x - 5 = 20 - 5
x = 15
Method 2.In order to open the bracket and isolate the variable x, we would first of all multiply both sides by 1/2 and then 5 as follows:
2/5(5 + x) = 8
Multiplying both sides by 1/2, we have:
1/2 × 2/5(5 + x) = 8 × 1/2
1/5(5 + x) = 4
Multiplying both sides by 5, we have:
5 × 1/5(5 + x) = 4 × 5
5 + x = 20
Subtracting 5 from both sides, we have:
5 + x - 5 = 20 - 5
x = 15
Method 3.In order to open the bracket and isolate the variable x, we would apply the distributive property of multiplication:
2/5(5 + x) = 8
2/5 × 5 + 2/5 × x = 8
2 + 2x/5 = 8
Subtracting 2 from both sides, we have:
2 - 2 + 2x/5 = 8 - 2
2x/5 = 6
Multiplying both sides by 5/2, we have:
5/2 × 2x/5 = 5/2 × 6
x = 30/2
x = 15.

A bookshelf is 31 3/4 inches wide 28 inch wide, binders on the shelf side-by-side how many binders can Maria place on the shelf?
Answers
The number of binder on the bookshelf is one
How to determine the number binders on the shelf?The given parameters are:
Width of the bookshelf = 31 3/4 inches
Width of the binders = 28 inches
From the question, we understand that the binders are stacked side by side
This means that the quotient of the width of the bookshelf and the width of the binder will give the number of binders
So, we have
Number of binders = Width of the bookshelf/Width of the binders
This gives
Number of binders = (31 3/4)/28
Evaluate the quotient
Number of binders = 1.13
Approximate
Number of binders = 1
Hence, there is only one binder on the bookshelf

Step-by-step explanation:
The formula is Weight on Mars= (Weight on Earth/9.81m/s2) * 3.711m/s2.
If a space rover has a mass of 3900 kg on Earth, the mass on Mars when it lands will be 3900kg.
What is Mass?Mass is a dimensionless quantity representing the amount of matter in a particle or object. The standard unit of mass in the International System (SI) is the kilogram.
Given,
The mass of a space rover is 3900 kg.
We need to check what is its mass in Mars.
The mass of space rover in Mars will also be same 3900 kg because the mars is same quantity it wont change according to place or time, it remains constant. Where as weight would be changed.
The mass of the object is always constant, anywhere it is on the Earth or Moon or any other planet.
