is it possible to have a regular polygon with measure of each exterior angle as 22
Answer:
No
Step-by-step explanation:
Number of sides of a polygon = 360°/measure each exterior angle
= 360°/22
= 16.36°
Since, answer is not a whole number, thus, a regular polygon with measure of each exterior angle as 22⁰ is not possible.
Thus the answer is no.
Answer:
No, it is not possible.
Step-by-step explanation:
The sum of the exterior angles = 360
360 divided by 22 = 16.36
As 16.36 is not a whole number an exterior angle of 22 degrees is not possible.

If arcLM = 8x-56 and arcNP = 5x+22, find arcLP.
Answer:
arcLP = 19
Step-by-step explanation:
Given the following
arcLM = 8x-56
arcNP = 5x+22
Required
arcLP
Given that arcLM = arcNP
8x-56 = 5x+22
8x - 5x = 22 + 56
3x = 78
x = 78/3
x = 26
Let assume arcLP = x - 7
arcLP = 26 -7
arcLP = 19

Determine the equation of a line that passes through the point (3,-2) and is PERPENDICULAR to the equation
y= 3x - 1
Can you please solve this
Step-by-step explanation:
To get the x intercepts you need to set y = 0.
So you will get:
[tex]x^{2}[/tex] - 4x - 12 = 0
which can then be put in the form of:
(x - 6) (x + 2) = 0
The x intercepts are: (6,0) and (-2,0).
For the vertex you would need to convert the equation to vertex form.
which is : y = a[tex](x-h)^{2}[/tex] =k
[tex]x^{2}[/tex] - 4x - 12 = y
turn it in to square form:
([tex]x^{2}[/tex] - 4x + 4) - 12 - 4 = y
[tex](x-2)^{2}[/tex] - 16 = y
so the vertex is = (2, -16)
simply the following: (2+5i)^2 - (2+i)
Answer:
- 23 + 19i
Step-by-step explanation:
[tex](2 + 5i)^{2} - (2 + i) \\ \\ = {2}^{2} + {(5i)}^{2} + 2.2.5i - 2 - i \\ \\ = 4 + 25 {i}^{2} + 20i - 2 - i \\ \\ = 4 - 25 + 20i - 2 - i \\ ( \because \: {i}^{2} = - 1) \\ \\ 4 - 25 - 2 + 20i - i \\ \\ = - 23 + 19i[/tex]

Aubrey worked at the concession stand during a recent sporting event at her high school. During the first hour of the event, she sold 11 orders of nachos and 18 tacos for a total of 64.95 . During the second hour, she sold 6 orders of nachos and tacos 15 for a total of 43.20.
Answer:
cost of nachos = $3.45
Cost of tacos = $1.5
Step-by-step explanation:
Let
x = cost of nachos
y = cost of tacos
11x + 18y = 64.95 (1)
6x + 15y = 43.20 (2)
Multiply (1) by 6 and (2) by 11 to eliminate x
66x + 108y = 389.70
66x + 165y = 475.20
Subtract to eliminate x
165y - 108y = 475.20 - 389.70
57y = 85.50
y = 85.50/57
y = 1.5
Substitute y = 1.5 to find x
11x + 18y = 64.95 (1)
11x + 18(1.5) = 64.95
11x + 27 = 64.95
11x = 64.95 - 27
11x = 37.95
x = 37.95/11
x = 3.45
cost of nachos = $3.45
Cost of tacos = $1.5
