Answer:

[tex]P_{m}=(6,10.5,9)[/tex]

Step-by-step explanation:

The mid point can be found with the formula

[tex]P_{m}=(\frac{x_{1}+x_{2} }{2},\frac{y_{1} +y_{2} }{2} ,\frac{z_{1}+z_{2} }{2} )[/tex]

The given coordinates are [tex]P(5,10,8)[/tex] and [tex]Q(7,11,10)[/tex].

Replacing coordinates in the formula, we have

[tex]P_{m}=(\frac{5+7}{2},\frac{10+11 }{2} ,\frac{8+10}{2} )=(\frac{12}{2},\frac{21 }{2} ,\frac{18}{2} )\\P_{m}=(6,10.5,9)[/tex]

Step-by-step explanation:

Answer:  y = -5x - 22

Step-by-step explanation:

Use the Point-Slope formula: y - y₁ = m(x - x₁)

y - (-2) = -5(x - (-4))

y + 2  = -5(x + 4)

y + 2 = -5x - 20

y       = -5x - 22

B)The volume of the pyramid is 1/3 the volume of prism

Step-by-step explanation:

We are given that

Bases of rectangular pyramid  and rectangular prism are same

Height of both  rectangular pyramid  and rectangular prism are same.

We know that

Volume of  rectangular pyramid =[tex]\frac{1}{3}bh[/tex]

Where b=Area of base

Volume of rectangular prism=[tex]bh[/tex]

Where b=Area of base

Volume of rectangular pyramid=[tex]\frac{1}{3}[/tex] volume of rectangular prism

Hence, the volume of pyramid is 1/3 times the volume of volume of rectangular prism.

Option  B is true.

The volume of the pyramid is 1/3      the volume of the prism.

Step-by-step explanation:

Answer:

A = 12 units^2

Step-by-step explanation:

The area of a trapezoid is

A = 1/2 (b1+b2)* h where b1 and b2 are the bases (which are parallel)

b1 = AT = 4 units

b2 = SR = 2 units

The heights is along the x axis which is 4 units

A = 1/2 ( 2+4) *4

A = 1/2 (6)*4

A = 12 units^2

The Average of rate is -1.

Step-by-step explanation:

Everytime it goes up by one the y goes down by 1 so it would be -1.

The function has an average rate of change of -1. It is denoted by R.

The single rate applies to property in several locations and is a weighted average of the separate rates that apply to each place.

The function has an average rate of change of -1.

[tex]\rm R = \frac{4-5}{1-0} \\\\ R=-1[/tex]

Answer:

Step-by-step explanation:

To use the formula for the volume of a prism to remember the formula for the volume of a cylinder, you can think of a cylinder as a prism with circular bases. The formula for the volume of a prism is given by multiplying the base area by the height. In the case of a cylinder, the base area is the area of a circle, which is πr² (where r is the radius), and the height is the height of the cylinder. Therefore, the formula for the volume of a cylinder becomes V = πr²h.

The formula for the volume of a cone is related to the formula for the volume of a cylinder because a cone can be thought of as a pyramid with a circular base. The formula for the volume of a cone is given by multiplying the base area (which is a circle) by the height and dividing by 3. Since the base area of a cone is πr² (where r is the radius), and the height of the cone is h, the formula for the volume of a cone becomes V = (1/3)πr²h. The volume of a cone is exactly one-third of the volume of a cylinder with the same base area and height.

It's important to note that the formulas for the volume of a cylinder, cone, and sphere are derived based on their geometric shapes and properties. Understanding these relationships and connections can help in remembering and applying the formulas correctly in problem-solving situations.

To remember the formula for the volume of a cylinder, think of it as a prism with circular bases. The formula is the area of the base times the height. The volume of a cone with the same radius and height is one-third of the volume of the cylinder.

The scale factor for the measurements on the map would be 11 x 10 ⁻⁵.

Scale factor is used to compare the size of two objects. Mathematically, we can write -

{K} = S{O1}/S{O2}

Given is that the distance between home and school is 4.5 miles. On a map it shows the distance to be 9 cm.

The distance between home and school : 4.5 miles.

On the map the distance between home and school is 9 cm.

We can write the scale factor as -

{K} = (9 x 5.5 x 10 ⁻⁵)/4.5

{K} = 11 x 10 ⁻⁵

plug in the end corrdinates like it says in the equation that the problem gives you.

The x and y-coordinates of the point C will be equal to (1.2, -4.7).

Using one or even more integers, or coordinates, a coordinate system in geometry establishes a unique way to locate points or other geometrical objects on a manifold, such as Euclidean space.

The order of the values is important, and they can sometimes be distinguished by their place in an arranged tuple or by a letter, such as "the x-coordinate."

As per the given information in the question,

Coordinates are the location of a point in an (x,y) plot.

The given coordinates are:

A = (7,-2)

B = (-8,-9)

m:n = 5:8

Answer: y=4

Step-by-step explanation:

8y+1=6y+9 -Because y is equal the equations are as well.

2y+1=9- Take 6y to the other side by -6y

2y=8-Take one over by -1

y=4-Divide 8 by 2 to get y=4

Answer:

The value of y is 4

Step-by-step explanation:

If the some of the counters in each box are the same, then A = B

If A is 8y + 1 and B is 6y + 9

Since A = B, we can say

8y + 1 = 6y + 9

Collecting like terms, we will have

8y - 6y = 9 - 1

2y = 8

Dividing both sides by 2, we will have

y = 8/2

y = 4

Step-by-step explanation:

It said on the "show me" box at the bottom of the screen :)

The required angle of the projectile motion having range 20 m and initial velocity 15 m is 30.29°

Range of the projectile motion:

The formula for finding projectile motion is given by

Range R = [tex]\frac{v^2sin2\theta}{g}[/tex]

where v is the initial velocity and g is acceleration and [tex]\theta[/tex] is the projectile angle of the object

If we have given range and initial velocity with acceleration then by substituting above range formula we can find angle of the projectile

Here we have given that

R = 20 m

v = 15 m/s

g = 9.8 m/s^2

Therefore

[tex]20=\frac{15^2sin2\theta}{9.8}[/tex]

[tex]sin2\theta=\frac{20(9.8)}{225}[/tex]

[tex]\theta[/tex] = 30.29

we can write the equation of the line in slope-intercept form:

[tex]y =[/tex][tex](-1/12)x + 6[/tex]

To find the equation of a line in slope-intercept form ([tex]y = mx + b[/tex]), we need to determine the slope (m) and the y-intercept (b).

Given two points (0, 6) and (12, 5), we can calculate the slope (m) using the formula:

[tex]m = (y2 - y1) / (x2 - x1)[/tex]

Using the coordinates (0, 6) and (12, 5):

[tex]m = (5 - 6) / (12 - 0)[/tex]

[tex]= -1 / 12[/tex]

Now that we have the slope (m), we can substitute it into the slope-intercept form equation:

[tex]y = mx + b[/tex]

Using the coordinates (0, 6):

[tex]6 = (-1/12)(0) + b[/tex]

6 = b

Therefore, the y-intercept (b) is 6.

A slope-intercept equation is a linear equation written in the form y = mx + b, where m represents the slope of the line and b represents the y-intercept. The slope (m) determines the steepness or direction of the line, while the y-intercept (b) is the point where the line intersects the y-axis. By using this equation, we can easily identify the relationship between the x and y coordinateson  the line, making it convenient for graphing, understanding the line's behavior, and predicting the value of y for a given x.

Answer:

6.3 yards high

Step-by-step explanation:

The three given points are (0,0), (1,6.86), and (2,3). Use these values in f(x) = ax2 + bx + c.

For (0,0), 0 = 0 + 0 + c.

So, c = 0.

For (1,6.86), 6.86 = a + b + c. Since c = 0:

a + b = 6.86(equation 1)

For (2,3), 3 = 4a + 2b + c. Since c = 0:

4a + 2b = 3(equation 2)

Multiply equation 1 by 2, and subtract the result from equation 2:

2a + 2b  = 13.72

4a + 2b - (2a + 2b)  = 3 - 13.72

2a  = -10.72

a  = - 5.36

Plug this value into equation 1:

-5.36 + b  = 6.86

b  = 12.22

So the function is f(x) = -5.36x2 + 12.22x.

When the ball hits the ground, the height is 0, or f(x) = 0:

Use the function to determine the height of the ball, f(x), after x = 1.5 seconds.

f(x) = -5.36x2 + 12.22x

= -5.36(1.5)2 + 12.22(1.5)

= 6.27

0 = -5.36x2 + 12.22x

0 ≈ x − 2.27(Divide both sides by -5.36x.)

x ≈ 2.27 ≈ 2.3

So, the ball will be about 6.3 yards high after 1.5 seconds.
