This circle is centered at the origin, and the length of its radius is 6. What is
the circle's equation?

Final answer:

To find the height of the ball on the 10th bounce, an explicit formula that accounts for the initial conditions and the coefficient of restitution is needed. However, without specific information, we cannot calculate the exact height. Each bounce would generally be lower than the previous due to energy losses.

Explanation:

Finding the Height After 10th Bounce

The question of finding the height of a ball on the 10th bounce involves understanding the kinematic equations of motion. However, the question seems to be missing explicit information to compute the height, such as the initial height, velocity, and the coefficient of restitution that would tell us how the bounce height decreases with each bounce.

Assuming that a standard formula governing the bounce height is given, for example, height of nth bounce = initial height × (coefficient of restitution)ⁿ⁻¹ , we could insert the values to find the height of the 10th bounce.

Since we don't have the specifics needed, we cannot calculate the exact height. For an exact answer, we would need additional information on the initial conditions and the physical properties of the ball and the surface.

However, based on general physics principles, each bounce would be lower than the previous one because some energy is lost with each impact due to factors like air resistance and the inelastic collision with the floor.

Answer:

A given point on a line graph represents a data point with the value of the responding variable as the height of the point at the given value of the manipulated variable on the horizontal axis.

Step-by-step explanation:

A given point in a line graph signifies a specific value of an ordered pair of variables. The x-coordinate represents one variable, and the y-coordinate another. It essentially reflects the relationship between these two variables at a particular time.

In mathematics, specifically in the field of graphs and data visualization, a given point on a line graph represents a specific value for an ordered pair of variables. The horizontal coordinate (x-value) stands for one variable, while the vertical coordinate (y-value) represents another variable.

For example, if we're graphing a student's test scores over time, the time period will be represented on the x-axis, and the test score would be represented on the y-axis. If we have a point at coordinates (3, 85), then that means the student scored 85 on their test in the third time period.

This single point, therefore, is a representation of the interaction or relation between these two variables at a particular interval.

Answer:

The radius is 5

Step-by-step explanation:

The equation for Area of a sphere is

4pi*r^2

Since you have the area and not the radius you do the opposite of the equation so instead of multiplying you divide

100/4 = 25

Then find the square root of 25, which is 5

So your radius is 5.

Answer:

Slope = 2/3 Y intercept +3

Step-by-step explanation:

Plot the y-intercept (0,+3) in the xy axis. Remember, this point always lies on the vertical axis y.

Starting from the y-intercept, find another point using the slope. Slope contains the direction how you go from one point to another.

The numerator tells you how much steps to go up or down (rise) while the denominator tells you how many units to move left or right (run).

Connect the two points generated by the y-intercept and the slope using a straight edge (ruler) to reveal the graph of the line.

Answer:

This is an obtuse triangle

Step-by-step explanation:

Pythagoras theorem is used to determine if a triangle is right, acute or obtuse

If the sum of squares of two shorter lengths is greater than the square of third side then the triangle is an acute triangle.

If the sum of squares of two shorter lengths is less than the square of third side then the triangle is an obtuse triangle.

If the sum of squares of two shorter lengths is equal the square of third side then the triangle is a right triangle.

so,

[tex](41)^2 = (36)^2+(9)^2\\1681 = 1296+81\\1681>1377[/tex]

As 1681>1377, the given triangle is an obtuse triangle ..

Answer:

B. See explanation

Step-by-step explanation:

Use the distance formula between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2):[/tex]

[tex]d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}[/tex]

Find the lengths of all sides of quadrilateral DEFG:

[tex]DE=\sqrt{(-a-b-0)^2+(c-2c)^2}=\sqrt{(a+b)^2+c^2}\\ \\

EF=\sqrt{(a+-b-0)^2+(c-2c)^2}=\sqrt{(a+b)^2+c^2}\\ \\

FG=\sqrt{(a+b-0)^2+(c-0)^2}=\sqrt{(a+b)^2+c^2}\\ \\

GD=\sqrt{(-a-b-0)^2+(c-0)^2}=\sqrt{(a+b)^2+c^2}\\ \\[/tex]

All sides are of the same length. Now fond the slopes of all sides:

[tex]DE=\dfrac{2c-c}{0-(-a-b)}=\dfrac{c}{a+b}\\ \\EF=\dfrac{c-2c}{a+b-0}=-\dfrac{c}{a+b}\\ \\FG=\dfrac{c-0}{a+b-0}=\dfrac{c}{a+b}\\ \\GD=\dfrac{c-c}{-a-b-0}=-\dfrac{c}{a+b}\\ \\[/tex]

The slopes of the sides DE and FG are the same, so these sides are parallel. The slopes of the sides EF and GD are the same, so these sides are parallel.

Answer:

The equation is y=(-1/7)x+-1 or y=(-1/7)x-1.

Step-by-step explanation:

slope-intercept for is y=mx+b where m is the slope and b is the y-intercept.

You are given (7,-2) and (0,-1).

Line them up and subtract vertically then put 2nd difference over 1st difference:

( 7, -2)

-(0 , -1)

-----------

7      -1

So the slope is -1/7.

Now we know our equation is in the form

y=(-1/7)x+b.

Use one of the points you are given along with y=(-1/7)x+b to find b.

I'm choosing (0,-1) to plug in for (x,y):

-1=(-1/7)(0)+b

-1=0+b

-1=b

So the equation is y=(-1/7)x+-1 or y=(-1/7)x-1.

y = -1/7x - 1

In this question, we're trying to find the slope-intercept form with the information that is given.

Slope intercept form is represented as y = mx + b

In this case, we know that the points are at:

With the information above, we can solve the problem.

In order to find the slope, we would use the slope equation.

Slope equation:

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

To use this slope equation, we would need to plug in the points from the coordinates into the equation. Your equation should look like this:

[tex]m=\frac{-1--2}{0-7}[/tex]

Now, you solve to find the slope of the line.

[tex]m=\frac{-1--2}{0-7} =\frac{1}{-7} =-\frac{1}{7}[/tex]

When you're done solving, you should get -1/7.

This means that the slope of the line is -1/7. We would plug 9 in our "m" variable.

Your slope intercept form should look like this:

y = -1/7x + b

For our "b" variable, it's going to be the beginning point. When we look at our (0,-1) coordinate, we would know that -1 would be our beginning point, sicne thje 0 is on the x and there's a variable for the y.

Your slope intercept form should look like this:

y = -1/7x - 1

This means that the slope intercept form of the line is y = -1/7x - 1

Answer:

2a) [tex]g(x)=3x-6[/tex]

2b) This is a show kind of answer. The showing of this in the explanation.

2c) I provided the graph.  The lines should be a reflection through the y=x line.  The points (a,b) on y=(1/3)x+2 or swapped to get the points (b,a) on y=3x-6. That is for, example the point (-3,1) is on y=(1/3)x+2 while (1,-3) is on y=3x-6.

Step-by-step explanation:

2a) The inverse of a function is you just swapping x and y around. You also almost always asked to remake y the subject after that though.

So anyways we have this equation [tex]y=\frac{1}{3}x+2[/tex] to represent that function you have there.

We want to swap x and y:

[tex]x=\frac{1}{3}y+2[/tex]

Now we want to solve for y.

Subtract 2 on both sides:

[tex]x-2=\frac{1}{3}y[/tex]

Multiply both sides by 3:

[tex]3(x-2)=y[/tex]

[tex]y=3(x-2)[/tex]

Distribute:

[tex]y=3x-6[/tex]

So they want us to name the inverse g(x).

[tex]g(x)=3x-6[/tex]

2b) We want to show by composition that these functions are inverses.  That is we want to show f(g(x))=x and g(f(x))=x.

Let's do that:

f(g(x))

Replace g(x) with 3x-6 since g(x)=3x-6.

f(3x-6)

Replace the old input x with the new input (3x-6) in (1/3)x+2.

[tex]\frac{1}{3}(3x-6)+2[/tex]

Distribute:

[tex]\frac{3x}{3}-\frac{6}{3}+2[/tex]

Simplify:

[tex]x-2+2[/tex]

[tex]x-0[/tex]

[tex]x[/tex].

So we do have f(g(x))=x.

Now to show the other way:

g(f(x))

Replace f(x) with (1/3)x+2 since f(x)=(1/3)x+2.

g((1/3)x+2)

Replace the old input x with the new input (1/3)x+2 in 3x-6.

3((1/3)x+2)-6

Distribute:

[tex]3(\frac{1}{3})x+3(2)-6[/tex]

Simplify:

[tex]1x+6-6[/tex]

[tex]x+6-6[/tex]

[tex]x+0[/tex]

[tex]x[/tex]

So we do have g(f(x))=x.

We have confirmed that f and g are indeed inverses since f(g(x))=x and g(f(x))=x.

2c) Visually if two functions are inverses they should be reflections through the y=x line so that is what we should see since f and g are inverses.

I going to compare both equations to y=mx+b form to determine the y-intercept and the slope.

y=mx+b

y=(1/3)x+2 tells us the slope is 1/3 and the y-intercept is 2.

y=3x-6 tells us the slope is 3 and the y-intercept is -6.

I have color-coded the picture.

Answer:

0.0268.

Step-by-step explanation:

This question can be solved using the binomial theorem.

Total attempts = n = 11

Required attempts = r = 5

Probability of success = p = 3/4 = 0.75

Binomial Theorem formula:

P(X=r) = nCr * p^r * (1-p)^(n-r).

Substituting the values:

P(X=5) = 11C5 * 0.75^5 * 0.25^6 = 0.0268 (to the nearest 3 significant figures).

So the probability that exactly 5 free throws are made out of 11 is 0.0268!!!
