Matching the specific Polygons with their descriptions, we have;
15-gon → An exterior angle measures 24°
16-gon → The Sum of interior angles is 2520°
12-gon → An interior angle measures 150°
18-gon → An interior angle measures 160°
What is the sum of interior angles of a Polygon?The formula for sum of interior angles of a Polygon is;
S = (n - 2) * 180
where n is number of sides of polygon. Thus;
1) For a 15 sided polygon;
Sum = (15 - 2) * 180
Sum = 13 * 180
Sum = 2340
Sum of exterior angles of a polygon is; 360°
Thus, external angles = 360/15 = 24°
2) For a 16 sided polygon;
Sum of interior angles = (16 - 2) * 180 = 2520°
3) The value of the interior angles of a polygon with 12 sides is;
(12 -2) * 180/12 = 150°

Answer:
a) 34.4 cm,b) 49.4 cmStep-by-step explanation:
The distance from the center to the chord is the perpendicular bisector of the chord.
The three segments form a right triangle:
The radius - hypotenuse,The half-length of the chord - leg,The distance to the chord - another leg.a) Use Pythagorean to find the radius:
r² = (56/2)² + 20²r² = 28² + 20²r² = 1184r = √1184r = 34.4 cm (rounded)b) Let the half-chord is x cm long. Use Pythagorean to find the missing leg:
34.4² = x² + 24²1184 = x² + 576x² = 1184 - 576x² = 608x = √608x = 24.7 cm (rounded)The length of the chord is:
24.7*2 = 49.4 cmTina's kitchen has an area of 54 square feet the kitchen is 9 times as many square feet does Tina's pantry if the pantry is 2 feet wide what is the length of the Pantry in feet
From the information given, the area of the kitchen is 54 square feet and it is 9 times as many square feet as does Tina's pantry. This means that the area of Tina's pantry is
54/9 = 6 square feet
If the pantry is 2 feet wide, we would determine its length by applying the formula for determining the area of a rectangle which is expressed as length * width
Therefore,
2 * length = 6
length = 6/2 = 3 feet
Length of the pantry is 3 feet

8x^2+8x-22 In (x-p)^2=q
The given function 8x^2+8x-22 rewritten using the completing the square method is (x+1/2)^2 = 3
Completing the square methodBy altering the equation's form so that the left side is a perfect square trinomial, a quadratic equation can be solved using the "Completing the Square" approach.
Given the quadratic equation below;
8x^2+8x-22 = 0
This can be simplified into the equation below;
8x^2+8x-22 = 0
4x^2+4x-11 = 0
Add 11 to both sides of the equation
4x^2+4x-11 + 11= 0 + 11
4x^2+4x = 11
Factor out 4x from the expression;
4(x^2+1) = 11
(x+1/2)^2 = 11/4 + 1/4
(x+1/2)^2 = 12/4
(x+1/2)^2 = 3
Hence the expression in the form of (x-p)^2=q is (x+1/2)^2 = 3

Mr. Coffey bought a house for $195,000. He made a 20% down payment. The interest rate is 5.25% for 30 years. How much does he need to borrow? What is his monthly payment?
Explanation:
Mr. Coffey bought a house for $195,000 with a 20% down payment.
A 20% down payment, would be 0.20, so $195,000 times 0.20 equals $39,000. Then $195,000 - $39,000 = $156,000.
He bought the bouse for $156,000.
5.25% is 0.525, because you move the decimals back. Understanding the total cost of the house is $156,000 now, we can do $156,000 times 5.25% (0.0525) which equals $8,190.
He would pay $8,190 every 30 years. (if this was the interest rate.)
Assuming if the cost was 20% down payment with the 5.25% interest rate then it would have been: $39,000 times 5.25% = 2047.5.
He would pay $2,047.50 every 30 years. (if this was the interest rate.)
There was no context between the interest rate, so let's assume the obvious which is $2,047.50 every 30 years.

STEP 1: Write the given function.
[tex]f(x)=\frac{1}{(x+3)}-2[/tex]STEP 2: Explain the means to use to find the required values
Since we were given a graph and can not use a caculator, we will be using the graph to get the values.
STEP 3: Plot the given function on a graph
STEP 4: Get the domain of the function
Domain: The domain is all x-values or inputs of a function. The domain of a graph consists of all the input values shown on the x-axis.
[tex]\begin{gathered} The\text{ domain from the graph is given as:} \\ x<-3\text{ or }x>-3 \\ \text{The interval notation is given as:} \\ (-\infty,-3)\cup(-3,\infty) \end{gathered}[/tex]STEP 5: Get the Range of the function
The range is all y-values or outputs of a function.
[tex]\begin{gathered} \mathrm{The\: set\: of\: values\: of\: the\: dependent\: variable\: for\: which\: a\: function\: is\: defined} \\ \text{The range of the graph is given as:} \\ f(x)<-2\text{ or }f(x)>-2 \\ \text{The interval notation is given as:} \\ (-\infty,-2)\cup(-2,\infty) \end{gathered}[/tex]STEP 6: Get the value on which the function is increasing on
[tex]\begin{gathered} \mathrm{If}\: f\: ^{\prime}\mleft(x\mright)>0\: \mathrm{then}\: f\mleft(x\mright)\: \mathrm{is\: increasing.} \\ \mathrm{If}\: f\: ^{\prime}\mleft(x\mright)<0\: \mathrm{then}\: f\mleft(x\mright)\: \mathrm{is\: decreasing.} \end{gathered}[/tex]STEP 7: Get the value on which the function is decreasing on
[tex]\begin{gathered} \mathrm{If}\: f\: ^{\prime}\mleft(x\mright)<0\: \mathrm{then}\: f\mleft(x\mright)\: \mathrm{is\: decreasing.} \\ It\text{ can be s}een\text{ that the function on the graph decreases on the point betw}een\text{ negative infinity} \\ \text{and -3 and the point betw}een\text{ -3 and infinity. }\therefore This\text{ can be written as:} \\ \: \\ \mathrm{Decreasing}\colon-\infty\:STEP 8: Get the values of the asymptotes
An asymptote is a line that a graph approaches without touching. Similarly, horizontal asymptotes occur because y can come close to a value, but can never equal that value. In the previous graph, there is no value of x for which y = 0 ( ≠ 0), but as x gets very large or very small, y comes close to 0.

the equation of the line in slope intercept form is
y-=mx+b
we have
m=2
b=3/2
substitute
y=2x+3/2
answer is option C
a certain linear function can be described by the equation below
We are given the information that the equation of the line is of the form:
y = a x + b
where a is a negative number and b is a positive number.
And we are asked to select among a number of options that represent the situation.
SInce b is a positive number (being "b" what is understood as the y-intercept) the line DOESN'T pass through the origing of coordinates. So the first option is discarded.
SInce "a"is a negative number (this is the so called "slope' of the line) the line must be slanted, and dropping from left to right Therefore option b is also discarded because that represents a line going up from left to right.
Option c is also discarded, because a is a negative number (not a zero) and lines parallel to the x axis have slope zero.
The last option is the correct one, since the intercept oo the y-axis is at a positive value for y, the line must be going down due to the negative slope, and therefore going across the II, I and IV quadrant as shown below: (give me a few minutes to draw a line with this characteristics)
Then, please mark the last option (d) as the correct answer.
Graph the line with slope 1/3
and y-intercept -2.
The equation of a straight line is y = mx + b where m is the slope and b is the y-intercept then the two points exist (0, -2) and (6, 0).
What is meant by the equation of a straight line?A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis. On the y-axis, this value c is referred to as the intercept. Y = mx + c represents the equation of a straight line with gradient m and intercept c on the y-axis.
The equation of a straight line is:
y = mx + b where m is the slope and b is the y-intercept.
Therefore, the equation for this line is:
y = (1/3)x - 2
To graph it we can identify two points on the line and connect them.
If x = 0, then y = -2 this is the y-intercept given in the problem.
If x = 6, then y = 0 this is the x-intercept
Therefore, the two points exist (0, -2) and (6, 0).
