Answer:
x = 37
y = 79
Step-by-step explanation:
Remark
We are going to go through an extensive discussion of the value of x. The value for y is found exactly the same way.
Top diagram.
The top diagram establishes the fact that if any two points are on the major arc of the circle whose center is 0, then the vertex of the of the two angles so formed are equal. The end points of these two angles must be established by the endpoints of the chord A and B.
Put in much simpler language.
<ACB = <AC'B
The end points of the angles are A and B of the Chord AB.
The Vertex of the angles are both on the major arc of the circle. These two are C and C'
Bottom Diagram
The idea here is to find the value of C. If we do that, then we know what x is in the diagram you provided.
Draw diameter COA Construction
< CAB = 90 Any vertex (C) on circumference with diameter endpoints (A & C) = 90
<CAT_1 = 90 A diameter always meets a tangent at 90o
<BAT_1 = 37 Given
<CAB = 90-37 <CAB and <BAT_1 are complementary
<ACB = 37 A right triangle's acute angles are complementary.
<ACB = x = 37o See top diagram

Answer:
[Verse 1]
We're waiting every night
To finally roam and invite
Newcomers to play with us
For many years, we've been all alone
We're forced to be still and play
The same songs we've known since that day
An imposter took our life away
Now, we're stuck here to decay
[Pre-Chorus]
Please let us get in
Don't lock us away
We're not like what you're thinking
We're poor little souls
Who have lost all control
And we're forced here to take that role!
We've been all alone
Stuck in our little zone since 1987
Join us, be our friend or just be stuck and defend
After all, you only got...
[Chorus]
Five Nights at Freddy's
Is this where you wanna be?
I just don't get it
Why do you wanna stay?
Five Nights at Freddy's
Is this where you wanna be?
I just don't get it
Why do you want to stay?
Five Nights at Freddy's
[Verse 2]
We're really quite surprised
We get to see you another night
You should have looked for another job
You should have said to this place goodbye
It's like there's so much more
Maybe, you've been in this place before
We remember a face like yours
You seem acquainted with those doors
[Pre-Chorus]
Please let us get in
Don't lock us away
We're not like what you're thinking
We're poor little souls
Who have lost all control
And we're forced here to take that role!
We've been all alone
Stuck in our little zone since 1987
Join us, be our friend or just be stuck and defend
After all, you only got...

Step-by-step explanation:
A power function with form y = ax passes through the points (2,
5
and 3,
81
Find the constants a
and pa=
p=
Answer: a = 47.3;
p = 0.65
Step-by-step explanation: A power function is of the form [tex]y=ax^{p}[/tex] and passes through points (2,5) and (3,81), i.e.:
[tex]5=a.2^{p}[/tex]
[tex]81=a.3^{p}[/tex]
To determine the two unknows, solve the system of equations:
[tex]log5=log(a.2^{p})[/tex]
[tex]log81=log(a.3^{p})[/tex]
Using multiplication and power rules:
[tex]log5=loga+plog2[/tex]
[tex]log81=loga+plog3[/tex]
Giving values to constants:
0.7=loga+0.3p
2=loga+0.5p
This system of equations can be solved by subtracting each other:
[tex]-1.3=-0.2p[/tex]
p = 0.65
Substituting p into one of the equations above:
[tex]loga+0.5(0.65)=2[/tex]
[tex]loga=1.675[/tex]
[tex]a=10^{1.675}[/tex]
a = 47.3
The constants a and p of the power function which passes through points (2,5) and (3,81) are 47.3 and 0.65, respectively.

Answer:
29
Step-by-step explanation:
2x - 14 = x + 15
2x - x = 15 + 14
x = 29
check
44 = 44
Answer:
pretty sure it's 29
Step-by-step explanation:
equation: 2x-14=x+15
how to solve: add 14 to both side, and subtract x from both sides. The equation will then be x=29.
I might be wrong tho.

----------------------------------------------
Explanation:
There are a lot of steps, so I broke things up into 3 sections or parts. The idea I'm applying is if the denominator is of the form [tex]a+\sqrt{b}[/tex], then multiplying top and bottom by [tex]a-\sqrt{b}[/tex] will rationalize the denominator. This is due to the difference of squares rule (step 3 of part 1). The following step shows squaring a square root has the two cancel out.
From that point, I simplified each square root and factored to cancel out a pair of '4's.
To expand out [tex](2-\sqrt{8})(4-\sqrt{12})[/tex], we can use either the FOIL method, the box method, or the distribution property. I used the distribution property.

a cylindrical can needs to have a volume of 6 cubic inches a label is to go around the side of the can. The function S(r)=12/r gives the area of the label in square inches where r is the radius of the can in inches
Answer:
Following are the solution to this question:
Step-by-step explanation:
Please find the complete question in the attachment.
Cylinder volume V= 6 Cubes - inch
The Formula:
[tex]\to V=\pi r^2 h= 6[/tex]
The (r and h ) is the radius and height of the cylinder and [tex]s(r)= \frac{12}{r}[/tex]represent the region of the mark in this r and h, and that is why as can's radius gets bigger and larger, the label area gets closer to 0.
Answer:
A cylindrical can needs to have a volume of 6 cubic inches. A label is to go around the
side of the can. The function gives the area of the label in square inches
where is the radius of the can in inches
Step-by-step explanation:
The verticles of triangle A are (-1,3) B (7,9) and C (15,-3) Find the coordinates of the intersection of the medians.
please help
Step-by-step explanation:
Coordinates of A≡(−1,3)
Coordinates of B≡(7,9)
Coordinates of C≡(15,-3)
The median through the vertex C will meet at the mid point of AB.
Coordinate of mid-point on AB=[(-1+7)/2 , (3+9)/2]= (3,6)
Now,
Length of median through vertex C= Distance between (15,-3) and (3,6)
Therefore,
Length of median = √(3-15)²+(6-(-3))²=√144+81=15unit
Hence the length of median through the vertx C is 15 units.

Part of a regular polygon is shown below. Each interior angle is 150°. (4
150°
Diagram not
accurately drawn
Calculate the number of sides of the polygon.
Answer:
12 side polygon
Step-by-step explanation:
Interior angle of n side regular polygon: = ((n-2)x180)/n
((n-2)x180)/n = 150
(n-2)x180 = 150n
180n - 360 = 150n
30n = 360
n = 12
check: (12-2)x180/12 = 150
Answer:
The polygon has 12 sides (a dodecagon).
Step-by-step explanation:
Angles in a Regular Polygon
A polygon with n sides has a total sum of internal angles equal to 180°(n-2). This means that each angle (in a regular polygon) measures
[tex]\displaystyle \frac{180(n-2)}{n}[/tex]
We are given the interior angle of 150°, thus:
[tex]\displaystyle \frac{180(n-2)}{n}=150[/tex]
Multiplying by n:
[tex]\displaystyle 180(n-2)=150n[/tex]
Operating
[tex]\displaystyle 180n-360=150n[/tex]
Rearranging and simplifying:
[tex]\displaystyle 180n-150n=360[/tex]
[tex]\displaystyle 30n=360[/tex]
[tex]n=360/30=12[/tex]
n = 12
The polygon has 12 sides (a dodecagon).

How many solutions does the system of equations below have?
x − 4y = 6
2x − 8y = 12
Answer:
One solution
Step-by-step explanation:
x - 4y = 6
-4y = 6 - x
-4y/-4 = 6/-4 -x/-4
y = -6/4 + -x/4
2x − 8y = 12
-8y = 12 - 2x
-8y/-8 = 12/-8 - 2x/-8
y = -12/8 + 2x/8
Graph "y = -6/4 + -x/4" and "y = -12/8 + 2x/8" to find how many solutions these lines have.
As shown below, it has only one solution.
