Answer:

The polygon is a triangle, and is not a regular polygon.

Step-by-step explanation:

The polygon is a triangle because of it's three sides. It's also a non regular polygon since it's no equilateral or equiangular.

Answer:

d. 12√37 / 37

Step-by-step explanation:

standard formula for the distance between a point (x₀,y₀) and a line ax+by+c=0 is |a*x₀ + b*y₀ + c| / √a²+b²

(x₀,y₀) : (-2 , 3)

ax+by+c=0 : 6x - y +3 = 0

x₀ = -2      y₀ = 3     a = 6       b = -1        c = 3

d = | 6*(-2) + (-1)*3 + 3 | / √6²+(-1)²

d = 12 / √37 = 12√37 / 37

Answer:

  316.7 ft³

Step-by-step explanation:

The formula for the volume of a cone is ...

  V = 1/3πr²h

Here, the radius (r) is half the diameter, so is 7.7 ft. Then the volume is ...

  V = 1/3π(7.7 ft)²(5.1 ft) = 100.793π ft³ ≈ 316.6505 ft³

The volume of the cone is about 316.7 cubic feet.

_____

If you use the inappropriate value 3.14 for π, your answer will be 316.5 ft³.

$123 if we round to the nearest whole number

Answer:

32boys

and

total of 56 students

Step-by-step explanation:

8:6

[tex]x \times \frac{6}{14} = 24 [/tex]

[tex]x = 24 \div \frac{6}{14} [/tex]

[tex]x = 56[/tex]

so,

[tex]56 \times \frac{8}{14} = 32[/tex]

We have two types of textbooks. Let's use "x" to represent the number of math textbooks and "y" to represent the number of history textbooks.

Altogether, the bookseller sold 240 math and history textbooks. So:

x + y = 240

Now, the number of history textbooks sold was 72 less than the number of math books sold. So:

y = x - 72

Now we can substitute for y in the equation and solve:

x + y = 240

x + (x - 72) = 240

2x - 72 = 240

2x = 312

x = 156

The bookseller sold 156 math textbooks.

Since y = x - 72, he must have sold 84 history textbooks.

Let's check our answers:

x + y = 240

156 + 84 = 240

That is true, so we did get the correct answers.

Answer:

the answer is 2 hours

Step-by-step explanation:

t = 0 belongs to the interval [-3, 3] (since -3 ≤ 0 ≤ 3 is true), so use the middle function to evaluate h (0):

h (0) = 0 × (0 + 4) = 0

Answer:

y = (2/3)x + 19/3

Let me know if there are any parts of the process you do not understand.

Step-by-step explanation:

First you need to know what slope is, if you do not let me know and I can explain it in depth.

Now, you can determine if a line is parallel or perpendicular  by its slope.  parallel has the same slope and perpendicular has the negative reciporical, which basically means negative 1 divided by the slope.  

So if you slope was 3 perpendicular would be -1/3.  if the slope is a fraction you can just flip the fraction and make it negative.  so if the slope is  -2/3 a perpendicular slope would be 3/2, making a negative number negative makes it positive.

Now you start with 2x - 3y = 12.  To find the slope I like putting it in slope intercept form.  basically somethign that looks liek y = mx + b.  to do that just use algebra on what you have to get y by itself.  here is how I would do that.

2x - 3y = 12 first subtract 2x from both sides

-3y = 12 - 2x Now divide both sides by -3

y = 12/-3 - (2x)/3 Now simplify

y = -4 + 2/3 x Now rarrange to make it look like I said, basically you want the x first.

y = 2/3 x - 4

There, so the slope is 2/3.  A parallel line will have the same slope.

To make the equation of a line  you want one point and the slope.  Well we have that, the point is (-2,5) and the slope is 2/3.

To find a line you set up the point slope form.  that is y - y1 = m(x - x1) where m is the slope and x1 and y1 are the coordinates of the point you need.  I will plug all that in.

y - y1 = m(x - x1)

y - 5 = (2/3)(x - (-2))  Now solve

y - 5 = (2/3)x + 4/3

y = (2/3)x + 19/3

So that is the equation of a line parallel to 2x - 3y = 12 that passes through (-2, 5)

Answer:

Scalene right

Step-by-step explanation:

So there's a right angle in the corner over there, so we know it's going to be ___ right triangle. And none of the sides are the same length, so its scalene

hope this helps:)

Step by step explanation :

The two points are ,

We can find the midpoint by finding the median of x coordinate and y coordinate .

[tex]\tt\to Midpoint = \bigg(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\bigg)\\\\\tt\to Midpoint =\bigg(\dfrac{-3+1}{2},\dfrac{-5-3}{2}\bigg)\\\\\tt\to Midpoint = \bigg( \dfrac{-2}{2},\dfrac{-8}{2}\bigg) \\\\\sf\to\boxed{\orange{\tt Midpoint = (-1,-4)}}[/tex]
