C. 15.7 cm
D. 31.4 cm
Answers
Answer:
31.4 cm , just did the quiz
Step-by-step explanation:
The length of the minor arc is 31.4 cm of the given circle.
What is Circle?A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
Arc length is the distance between two points along a section of a curve.
The formula for arc length is θ/360×2πr
Arc length = θ/360×2πr
Where θ is the central angle and r is the radius of the circle.
θ = 60 degrees and r is 30 cm
Plug in the value of θ and r
Arc length = 60/360 × 2×3.14×30
=1/6×60×3.14
=188.4/6
=31.4
Hence, the length of the minor arc is 31.4 cm of the given circle.

As a retiring employee, you'll receive 5.96% of your average salary from the last five years you worked with your company.
You plan to retire after 37 years with the company.
Your salaries for your last five years are:
$180,267
$210,325
$126,591
$77,184
$173,175
Calculate your annual retirement salary.
Answers
Answer:
9,149.10
Step-by-step explanation:
To get the average you take all the values and add them up then divide by 5.
767,542 divided by 5 = 153,508.40
Now to get the percentage take 5.96 and divide by 100 = 0.0596
With this you can multiple the average by the percent in decimal form.
153,508.40 * 0.0596 = 9,149.10

Graph the quadratic functions y =-2x^2 + 4 on a separate piece of paper. Using those graph, compare and contrast the shape and position of the graphs.
Answers
Answer:
y = 2x^2 is a parabola opening up with it's vertex at (0,0)... y=3x^2 -4 is also a parabola opening up, but it is 'thinner' in that it rises in y faster and it's vertex is at (0,-4)
Step-by-step explanation:
all equations of the type y = ax^2 + b are parabolas centered on the y-axis, soo the vertex is always on (0,b)
If a is positive then the parabola opens up,
the bigger a is, the 'thinner' the graph is, i.e. the faster the graph rises
the value of b determines the location of the vertex, if b is added, then the vertex rises over the x-axis, if b is subtracted then the vertex is below the x-axis

Answer:
a. 9(2m+7)
b. 4(3r-1)
Step-by-step explanation:
When factoring out the greatest common factor of expressions, first list the factors of the terms. Then, determine the greatest common factor between the two terms. After, "carry" that number out of the expression through division.
a. 18m+63
Start by listing the factors of 18 and 63.
18: 1, 2, 3, 6, 9, 18
63: 1, 3, 7, 9, 21, 63
The greatest common factor of 18 and 63 is 9, so we can carry 9 out of the expression through division:
18m+63
= 9(2m+7)
b. 12r-4
Start by listing the factors of 12 and 4.
12: 1, 2, 3, 4, 6, 12
4: 1, 2, 4
The greatest common factor of 12 and 4 is 4, so we can carry 4 out of the expression through division:
12r-4
= 4(3r-1)

To determine the number of deer in a forest, a naturalist catches, tags, and releases 15 deer. Later, 20 deer are caught, and 6 have tags. Estimate the number of deer in the forest.
Answers
Answer:
50 deer in the forest.
Step-by-step explanation:
Since this is a ratio problem and we are given three values and a single unknown (total number of deer) we can use the Rule of three to solve for the variable. We do this by multiplying the diagonal values and then dividing by the last available value. That will give us the value of the variable which in this case would be represented as x.
20 deer <======> 6 tagged
x deer <======> 15 tagged
(20*15) / 6 = x
300 / 6 = 50 total deer
Based on these values we can estimate that there are a total of 50 deer in the forest.

At midnight, the temperature in a city was 5 degrees Celsius. The temperature was dropping at a steady rate of 2 degrees Celsius per hour.
Write an inequality that represents t, the number of hours past midnight, when the temperature was colder than -4 degrees Celsius. Explain or show your reasoning.

A number line with the numbers negative 4 through 10, in increments of 2, indicated.
Answers
Answer:
(5-2t)<-4
Step-by-step explanation:
The temperature is 5 °C at midnight, and it is dropping at a speed of 2 °C each hour. If it's past midnight, the temperature will be t degrees after t hours ( 5 - 2t ). If the temperature is below - 4 ℃, the inequality can be ( 5-2t ) - 4
