A 100 g ball and a 50 g ball are dropped from a tower. both balls are the same size and there is no air resistance. which answer best describes how they fall? responses both balls hit the ground at the same time. both balls hit the ground at the same time. the 100 g ball hits the ground first. the 100 g ball hits the ground first. the 50 g ball hits the ground first.

Answers

When the 100 g ball and a 50 g ball are dropped from a tower. both balls are the same size and there is no air resistance, B. both balls hit the ground at the same time.

How to illustrate the information?

When an object moves through the air, air resistance acts as a force. When a body is moving through the air, this force works in the opposite direction. A frictional force is applied to the moving body by air resistance. Air resistance causes a body's speed to slow down as it moves.

Because air resistance slows down the motion of the falling object, it impacts acceleration during a fall to a lesser extent than gravity (g). The object's surface area and speed both influence how much it slows down.

Therefore, when the 100 g ball and a 50 g ball are dropped from a tower. both balls are the same size and there is no air resistance, both balls hit the ground at the same time.

a. f is defined at x = 3

c. f is defined at x = -3
d. f is defined at x = 2

Answers

The correct answer is option D. ([tex]f[/tex] is defined at [tex]x = 2[/tex])

The rational Function is continuous at a given value if its Denominator is not zero. In this exercise, we proceed to Factor the expression by check the value Denominator for each value of [tex]x[/tex].

[tex]f(x) = \frac{x^{2}-x-6}{x^{2}-9}[/tex]

You use a line of best fit set of data to make a prediction about an unknown value. The correlation coefficient for your data set is 0.793. How confident can you be that your predicted value will be reasonable close to the actual value?

Answers

Answer:

Moderately confident

Step-by-step explanation:

Given that :

Correlation Coefficient = 0.793

The correlation Coefficient gives the strength of relationship between linear variables ranging from - 1 to 1.with values close to either - 1 or 1 depicting strong negative or positive correlation respectively, while values close to 0 signifies a weak correlation. Since the correlation Coefficient Given by the model is close to 1(0.793) one can be moderately confident that the value obtained from the model will be reasonably close to the actual value.

Answers

Answer:

3

Step-by-step explanation:

Given the function f(x) = (5x+1)/2

We are to find the inverse first as shown;

let y = f(x)

y = (5x+1)/2

Replace y with x

x = (5y+1)/2

Make y the subject of the formula;

2x = 5y+1

5y = 2x-1

y = (2x-1)/5

f^-1(x) = (2x-1)/5

f^-1(8) = 2(8)-1/5

f^-1(8) = 16-1/5

f^-1(8) = 15/5

f^-1(8) = 3

Hence the answer is 3

D. x-4y=-4​

Answers

The equation of the straight line that has x-intercept 1 and y-intercept 4 is:

4x - y = 4

What is a straight line?

"A straight line is an endless one-dimensional figure that has no width. It is a combination of endless points joined on both sides of a point."

Given, the line has a x-intercept of 1 and y-intercept of 4. T

Therefore, the line passes through the points (1, 0) and (0, 4).

Now, we can find the slope of the line 'm' that passes through those either points.

Therefore, (x₁ - x₂) = m(y₁ - y₂)

⇒ (1 - 0) = m(0 - 4)

⇒ m = [tex]\frac{1}{4}[/tex]

Now, the equation of the line that has x-intercept 1 and y-intercept 4 is:

(x - x₁) = m(y - y₁)

⇒ (x - 1) =      [tex]\frac{1}{4}[/tex](y - 0)

⇒ 4(x - 1) = y

⇒ 4x - y = 4

Answer:

x = 7 + √61 ÷ 6

Step-by-step explanation:

3p² - 7p - 1 = 0 is a given equation

3p² - 7p - 1 = 0

Here,

a = 3

b = - 7

c = - 1

Now, Discriminant

D = b² - 4ac

= (- 7)² - 4 (3)(- 1)

= 49 + 12

D = 61 > 0

So, Quadratic Equation

ax² + bx + c = 0

x = - b ± √b² - 4ac ÷ 2a

x = - (- 7) ± √(- 7)² - 4 (3)(- 1) ÷ 2(3)

x = 7 ± √61 ÷ 6

x = 7 ± √61 ÷ 6

x = 7 + √61 ÷ 6 or x = 7 - √61 ÷ 6

Not real Value

Thus, The real value of x is 7 + √61 ÷ 6

A mathematics teacher wanted to see the correlation between test scores and
homework. The homework grade (x) and test grade (y) are given in the accompanying
table. Write the linear regression equation that represents this set of data, rounding
all coefficients to the nearest hundredth. Using this equation, find the projected test
grade, to the nearest integer, for a student with a homework grade of 49.

Answers

The linear regression equation that represents this set of data is Y = -12.41 + 1.15x and the projected test  grade for a student with a homework grade of 49 is 44 and this can be determined by using the generalized equation of regression.

Given :

A mathematics teacher wanted to see the correlation between test scores and  homework. The homework grade (x) and test grade (y) are given in the accompanying  table.

The generalized regression equation is given below:

Y = a + bX   --- (1)

where b is given by the formula:

[tex]\rm b = \dfrac{N\sum XY-\sum X \sum Y}{N\sum X^2-(\sum X)^2}[/tex]

Now, substitute the values of the known terms in the above formula in order to determine the value of 'b'.

b = 1.15

and the formula of a is given below:

[tex]\rm a = \dfrac{\sum Y - b \sum X}{N}[/tex]

Now, substitute the values of the known terms in the above formula in order to determine the value of 'a'.

a = -12.41

Now, substitute the values of a and b in the equation (1).

Y = -12.41 + 1.15x

Now, at x = 49 the value of Y becomes:

Y = -12.41 + 1.15(49)

Y = 43.94
