A triangular prism has a triangular face with a base of 13.5 feet and a height of 18 feet. Its volume is 2,187 cubic feet. What is the length of the triangular prism?

Answers

Answer:

The prism has a length x and a width x. Since it is a square at the base both length and width are the same amount x. The height is "half the length of one edge of the base". Since the base is x, this makes it 1/2x.

The volume's prism is found using V = l*w*h. Substitute and simplify.

13.5 = x*x*1/2x

13.5 = 1/2 x^3

27 = x^3

3 = x

The prism is 3 by 3 by 1.5.

"of" indicates multiplication.

n = 156/100 • 70

Let's divide both sides by 70 to have one fraction one each side.

n/70 = 156/100

2. Describe a rigid motion or composition of rigid motions that maps the rectangular bench at (0, 10)and

the adjacent flagpole onto the other short rectangular bench and flagpole.

Answers

Answer:

See Explanation

Step-by-step explanation:

Given

Let the bench be B and the flagpole be T.

So:

[tex]B = (0,10)[/tex] --- given

The flagpole is represented by the triangular shape labelled T.

So, we have:

[tex]T = (6,9)[/tex]

See attachment for the rectangular bench and the flagpole

From the attached image, the location of the other bench is:

[tex]B' = (0,-10)[/tex]

And the location of the other flagpole is:

[tex]T' = (-6,9)[/tex]

So, we have:

[tex]B = (0,10)[/tex] ==> [tex]B' = (0,-10)[/tex]

[tex]T = (6,9)[/tex] ==> [tex]T' = (-6,9)[/tex]

When a point is reflected from [tex](x,y)[/tex] to [tex](x,-y)[/tex], the transformation rule is reflection across x-axis.

So the rigid transformation that takes [tex]B = (0,10)[/tex] to [tex]B' = (0,-10)[/tex] is: reflection across x-axis.

When a point is reflected from [tex](x,y)[/tex] to [tex](-x,y)[/tex], the transformation rule is reflection across y-axis.

So the rigid transformation that takes [tex]T = (6,9)[/tex] to [tex]T' = (-6,9)[/tex] is: reflection across y-axis.

What is the equation of the line that passes through the point (-6, -8) and has a slope of 1/3

Answers

Answer:

x^2 = (28)^2 + (45)^2

= 784 + 2025

= 2809

x = 53

The equation of the line is y = (1/3)x - 6.

What is an equation of a line?

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

The equation of a line is y = mx + c.

Now,

m = 1/3

And,

(-6, -8) = (x, y)

So,

y = mx + c

-8 = 1/3 x -6 + c

-8 = -2 + c

-8 + 2 = c

c = -6

Now,

y = mx + c

y = (1/3)x - 6

Thus,

The equation of the line is y = (1/3)x - 6.

When a player fields the ball, they catch it with their glove. They may catch the ball on the groundor in the air. If they catch the ball on the ground, they have to throw the ball to the infield players that are assigned to a base. If they catch the ball in the air, it is called a fly, and then the batter is out. There is an umpire in the field who is like a judge. The umpire decides if a runner is safe or out in the field. If a player is safe, they stay on the base. If they are out, then they go back to the dugout. There is a first baseman who catches the throws from the infielders. The team in the field tries hard to get batters out at first, so the first baseman is very busy. Then there are the second baseman and a third baseman who field the ball and guard their bases.
