Step-by-step explanation:
The "template" equation of a circle is:
[tex](x-h)^{2} + (y-k)^{2} = r^{2}[/tex]
All you're doing after that, is filling in the blanks:
h = 0
k = 5
r = 5
Answer:
Correct answer:
(x−0)² + ( y−5)²=5²
Explanation:
The equation of a circle is (x−h)²+(y−k)²=r²
The center is (0,5) or, written another way (h,k). Substituting 0 for h and 5 for k, our formula becomes (x−0)²+(y−5)²=5²
Finally, the formula of the circle is (x−0)²+(y−5)²=25

If the square of the longest side is equal to the sum of the squares of the other 2 sides then the triangle is right.
longest side = 30 , then 30² = 900
20² + 23² = 400 + 529 = 929 ≠ 900
Then the triangle is not right.
The triangle and the trapezoid share a 15 inch base and height of 10 inches.
The area of the trapezoid is less than twice the area of the triangle. Find the value of x. Explain your reasoning.
Can the area of the trapezoid be exactly twice the area of the triangle? Explain your reasoning.
Answer:
15 ; yes
Step-by-step explanation:
Base = 15 inches
Height = 10 inches
Area of triangle = 1/2* base * height
Area of triangle = 0.5 * 15 * 10
Area of triangle = 75 in²
Area of trapezium < 2(75)
Area of trapezium, A
A = 1/2*(x+b)h
x = top base ; b = bottom base ; h = 10
1/2*(x + 15)10 < 150
5x + 75 < 150
5x < 150 - 75
5x < 75
x < 15
Hence, Area of trapezoid :
A = 1/2 * (15 + 15)10
A = 1/2 * (30)10
A = 1/2 * 300
A = 150
Hence, Area of trapezium can be twice the area of triangle.
2(75) = 150

A regular pentagon has an apothem of 4 centimeters.
What is the area of the regular pentagon in square centimeters? Round your answer to
the nearest tenth.
Answer:
[tex] \boxed{A ≈ 58.1 \: cm^{2}} [/tex]
Step-by-step explanation:
When given a regular polygon.
s = a × 2 tan (π / n [radians]).
s = a × 2 tan (180 / n [degrees])
A = (n × s × a) / 2
Where s is the side length, n is the number of sides, a is the apothem length, and A is the area.
You may also see A = p × a.
Where p is the perimeter, the perimeter is the same as n × s.
The apothem is also known as the inradius.
______________________________________
Given a regular pentagon which has 5 sides, and an apothem of 4 cm.
s = 4 × 2 tan (180 / 5) = 4 × 2 × (0.726542528) = 8 × (0.726542528) = 5.81234022404.. ≈ 5.8 cm.
Now that we have sufficient information, we can now solve for the area.
A = (n × s × a) / 2
A = (5 × 5.81234022404.. cm × 4) / 2
A = (20 × 5.81234022404.. cm) / 2
A = (116.236804481.. cm²) / 2
A = 58.1234022404.. cm²
A ≈ 58.1 cm²
The area of the regular polygon is the amount of space it covers
The area of the regular polygon is 58.1 square centimeter
The given parameter is:
[tex]\mathbf{a=4}[/tex]
Start by calculating the side lengths using
[tex]\mathbf{s = 2a\ tan (\frac{180}{ n} )}[/tex]
Where n represents the number of sides.
In this case
[tex]\mathbf{n =5}[/tex]
So, we have:
[tex]\mathbf{s = 2a\ tan (\frac{180}{ 5} )}[/tex]
[tex]\mathbf{s = 2a\ tan (36)}[/tex]
Substitute 4 for (a)
[tex]\mathbf{s = 2 \times 4\ tan (36)}[/tex]
[tex]\mathbf{s = 8\ tan (36)}[/tex]
[tex]\mathbf{s = 5.8123}[/tex]
The surface area is then calculated as:
[tex]\mathbf{A = \frac{n \times s \times a}{ 2}}[/tex]
So, we have:
[tex]\mathbf{A = \frac{5 \times 5.8123 \times 4}{2}}[/tex]
[tex]\mathbf{A = 58.123}[/tex]
Approximate
[tex]\mathbf{A = 58.1}[/tex]
Hence, the area of the regular polygon is 58.1 square centimeter

Calculate the expected value of playing a lottery ticket game where each ticket costs $5, and the chance of having winning ticket is one in one million, and the payout for having a winning ticket is 4.9 billion dollars. Round the expected value to the nearest cent.
Answer:
$4895
Step-by-step explanation:
P(winning) = 1 / 1000000 = 0.000001
P(not winning) = 1 - 1/1000000 = 0.999999
Winning amount = 4,900,000,000 - 5 = 4899999995
Amount lost = - 5
__ X: - 5 _________ 4899999995
P(X) : 0.999999 ___ 0.000001
Expected value E(x) = Σx * p(x)
E(x) = - 5(0.999999) + 4899999995(0.000001)
E(x) = - 4.999995 + 4899.999995
E(x) = 4895
Hence, expected value is 4895

A helicopter flies from the airport on a course with a bearing of 21 degrees. After flying for 99 miles, the helicopter flies due east for some time. The helicopter flies back to the airport with a bearing of 227 degrees. How far did the helicopter fly on the final leg of its journey?
Answer:
Step-by-step explanation:
From the question we are told that:
Initial bearing [tex]\angle _1=21 \textdegree[/tex]
Initial distance [tex]d_1=99miles[/tex]
Final bearing [tex]\angle _2=227 \textdegree[/tex]
Let [tex]\triangle OAB[/tex] be the perimeter travailed
[tex]\angle OAB=90+21=111 \textdegree\\\angle ABO=270-227=43 \textdegree[/tex]
Generally the equation for OB using sine rule is mathematically given by
[tex]OB=99*\frac{sin111}{sin43}[/tex]
[tex]OB=135.52miles[/tex]
Therefore the helicopter flight on the final leg of its journey is
[tex]OB=135.52miles[/tex]
There are three colors of jellybeans in a jar: Red, orange, and yellow. On a random pick, the probability of getting a red jellybean is 1/8 and the probability of getting an orange jellybean is 1/4. What is the probability of getting a yellow jellybean?
Answer: 5/8
Step-by-step explanation:
Probability of getting a red jellybean = 1/8
Probability of getting an orange jellybean = 1/4
Probability of getting a yellow jellybean = 1 - (⅛ + ¼)
= 1 - (1/8 + 2/8)
= 1 - 3/8
= 5/8
Therefore, the probability of getting a yellow jellybean is 5/8

Answer:
18
Step-by-step explanation:
Since this is a multiple choice question, I will employ the guess and check method - meaning I will check each answer one by one.
Variable x = dimes = $0.10
Variable y = quarters = $0.25
Set up a system of equations:
x + y = 38
x(0.10) + y(0.25) = 6.80
Plug in each choice into the second equation. You can find the number of quarters that correspond to each number of dimes by using the first equation.
20 dimes:
20 + y = 38
y = 18
20(0.10) + 18(0.25) = 6.80
2 + 4.5 = 6.80
6.5 does not equal 6.80
Because dimes (x) are worth less than quarters (y), this result tells us the answer will be less than 20 dimes as with 20 or more we have less than $6.80. Another example just to show this is true:
38 dimes:
38 + y = 38
y = 0
38(0.10) + 0(0.25) = 6.80
3.8 + 0 = 6.80
3.8 does not equal 6.80.
Since x is worth less than y, we need more of y rather than x. Adding more x will only mean we will get a lower price. Adding more y will mean we get a higher price which is what we need. So only solve for x that is less than 20.
6
6 + y = 38
y = 22
6(0.10) + 32(0.25) = 6.80
0.60 + 8 = 8.60
8.60 does not equal 6.80.
This result is higher than what we wanted (6.80) which means we need more x. Now we only have to solve for x numbers that are greater than 6 and less than 20.
18
18 + y = 38
y = 20
18(0.10) + 20(0.25) = 6.80
1.8 + 5 = 6.8
6.8 does equal 6.8.
Correct!

Answer:
600ft²
Step-by-step explanation:
Oh boy, this is gonna be a long one, so proceed with caution:
So we're gonna start with the one to the very left, we can split this into three different rectangles:
So we got the length of the bottom minus the length we don't want there because we're doing the big rectangle:
35 - 10 = 25
25 x 20 = 500
So we're just gonna keep that on a back burner, cause now we gotta do the two smaller ones:
So we got the measure from the one side, but we gotta subtract the 10 from the other side:
20 - 10 = 10
10 x 10 = 100
Now we gotta add that all up:
500 + 100 = 600
So the area of the first shape is 600ft²
I gotta go, but hope this helps a little bit

The graph shows the population of a city from 1900 to 2000. What is the average rate of change of the population between 1950 and 1980?
Please help! I attached a photo of the graph.
Answer:
-15
Step-by-step explanation:
in 1950 it was 45 and in 1980 it was 30 so it is -15
The average rate of change can be define as the value of something is changing with respect to another thing is tinging. The average rate of change of the population between 1950 and 1980 is 500 per year. It means the population is decreasing with 500 per year.
Given information-The given graph shows the population of a city between the year 1900 to 2000.
Average rate of change-The average rate of change can be define as the value of something is changing with respect to another thing is tinging.
Form the given graph,
The year 1950 is between the year 1940 and year 1960. The value at the y axis where the population (in thousand) shown is 45,000 for the year 1950.
The year 1980 is shown in graph at the x axis and the value of the population in the y axis is 30,000.
Thus the population is decreasing from year 1950 to 1980. The difference in the population of the year 1950 and 1980 is,
[tex]d=45000-30000[/tex]
[tex]d=15000[/tex]
Thus the change in the population between 1950 and 1980 is 15,000.
Average rate of change of the population between 1950 and 1980 -
As the population and the year both are changing. The rate of change for the population with respect to the year can be calculating by dividing the difference of the population between two year to the total years between the 1950 to 1980.
There is total 30 year from 1950 to 1980, thus the average rate of change is,
[tex]A(x)=\dfrac{15000}{30} \\ A(x)=500[/tex]
Thus the average rate of change of the population between 1950 and 1980 is 500 per year. It means the population is decreasing with 500 per year.
