It should be noted that the rotation symmetry that an equilateral triangle has is 3.

<h3>What is rotational symmetry?</h3>

It should be noted that rotational symmetry simply means when an object is rotated on its own axis.

In this case, it should be noted that the rotation symmetry that an equilateral triangle has is 3.

Also, the number of degrees that you can rotate the shape to carry it onto itself will be 60°, 120°, and 180°.

The surface area of the triangular prism is 1664 square yards.

Explanation:

Given that a triangular prism is 20 yards long and has a triangular face with a base of 24 yards and a height of 16 yards . the other two sides of the triangle are each 20 yards.

<u>Surface area of the triangular prism:</u>

The formula to determine the surface area of the triangular prism is

$SA=bh+Pl$

where base $b=24$ ,

height $h=16$ ,

length $l=20$ and

Perimeter $P=20+20+24=64$

Substituting these values in the above formula, we get,

$SA=(24\times 16)+(64\times 20)$

$=384+1280$

$SA=1664$

Thus, the surface area of the triangular prism is 1664 square yards.

Answer:

B. 14.2, 3.2

Step-by-step explanation:

diameter: 9 (count each box as 1)

d/2 = radius --> radius: 4.5

Area of a circle= πr^2

A= 63.6172

A/r = 63.6172/4.5 = 14.1

A/r^2= 63.6172/(4.5)^2 = 3.14

The equation of the graphed line in slope point form using the point (2,-1 ) is blank and it’s equation in slope intercept is bl

valkas [14]

Answer:

$y=\frac{1}{4}x-\frac{3}{2}$ (Slope intercept form)

$y+1=\frac{1}{4}(x_-2)$ (Slope point form)

Step-by-step explanation:

The slope of the line can be calculated as following:

$m=\frac{-1-(-2)}{2-(-2)}=1/4$

The the equation of the line in slope point form is:

$y-y_1=m(x_-x_1)$

Where ( $x_1$ , $y_1$ ) is a point of the line.

Then you must susbtitute the point given and the slope and you obtain:

$y+1=\frac{1}{4}(x_-2)$

The intercept form is:

$y=mx+b$

Where b is the y-intercept.

Solve for y from the equation of the line in slope point form obtained above, then:

$y+1=\frac{x}{4}-\frac{2}{4}\\y=\frac{1}{4}x-\frac{2}{4}-1\\y=\frac{1}{4}x-\frac{3}{2}$
