Find the midpoint of the segment below and enter its coordinates as an
ordered pair. If necessary, express coordinates as fractions, using the slash
mark ( / ) for the fraction bar.
(4,0) (12,0)
Answers
Given:
The end points of a line segment are (4,0) and (12,0).
To find:
The midpoint of the line segment.
Solution:
Midpoint formula:
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
The end points of a line segment are (4,0) and (12,0). So, the midpoint of the line segment is:
[tex]Midpoint=\left(\dfrac{4+12}{2},\dfrac{0+0}{2}\right)[/tex]
[tex]Midpoint=\left(\dfrac{16}{2},\dfrac{0}{2}\right)[/tex]
[tex]Midpoint=\left(8,0\right)[/tex]
Therefore, the midpoint of the given line segment is (8,0).

Two years ago, there were 30 foxes in a forest. this year, there are 40 foxes in the forest. what is the annual percent growth for the foxes?
Answers
9514 1404 393
Answer:
about 15.5%
Step-by-step explanation:
The number of foxes in the forest can be modeled by the exponential equation ...
f = a·b^t
where a is the initial number, and b is the growth factor per year for t years. The growth factor is 1 more than the growth rate (r), so we can put numbers in this formula to get ...
40 = 30·(1 +r)^2
4/3 = (1 +r)^2 . . . . . . divide by 30
1 +r = √(4/3) . . . . . . take the square root
r = √(4/3) -1 ≈ 0.1547 ≈ 15.5%
The annual percentage growth in the fox population is about 15.5%.
A class consists of 20 sophomores and 15 freshmen. The club needs to choose four different members to be president, vice president, secretary, and treasurer. In how many ways is this possible if sophomores will be chosen as president and treasurer and freshmen as vice president and secretary?
Please explain your answer instead of just providing the answer for the points!
Answers
Answer:
There are 79,800 ways in which this is possible.
Step-by-step explanation:
The order in which the students are chosen is important(due to different roles), which means that the permutations formula is used to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]
In this question:
2 sophomores from a set of 20.
2 freshmen from a set of 15. So
[tex]P_{20,2}*P_{15,2} = \frac{20!}{18!}*\frac{15!}{13!} = 20*19*15*14 = 79800[/tex]
There are 79,800 ways in which this is possible.

Answer:
A. 15.250
Step-by-step explanation:
The applicable trig function is the cosine function:
Cos = Adjacent/Hypotenuse
cos(57°) = y/28
y = 28×cos(57°) ≈ 15.24989
y ≈ 15.250 . . . . matches choice A
_____
Additional comment
From your knowledge of "special" triangles, you know that y would be 14 if the angle were 60°. Of course, the length must be shorter than 28, so answer choices B and C are immediately eliminated. The fact that the length is closer to half of 28 than it is to 28 makes choice A look like a pretty good guess.

Answer:
288
Step-by-step explanation:
To solve, we need to find the area of the four triangle sides and add that to the square base's area.
Area of triangle sides: base * height * 0.5
Area of square base: base * height
Substitute the values
8 * 14 * 0.5 = 56
There are four of these sides, so the area of all the triangles is 224.
The square base is 8 * 8, or 64
Add these two values together.
64 + 224 = 288
Thus, the answer is 288
What growth factor would be needed to provide 1/12th of 12% interest each month
Answers
1.01 is the growth factor that would be needed to provide 1/12th of 12% interest each month.
What are exponential growth and decay?A rise in the resultant quantity for a given quantity is referred to as exponential growth, and a decrease in the resultant quantity for a given quantity is referred to as exponential decay. Over time, exponential functions monitor constant growth. Examples from the actual world include radioactive decay, compound interest, and bacterial proliferation.
Given, the growth factor would be needed to provide 1/12th of 12% interest each month
Remember the formulas:
Increasing: y = a (1 + r)ˣ
Decreasing: y = a(1 - r)ˣ
(1 ± r is the growth factor, while r is the growth rate)
In our case,
since it is an interest It will show the growth rate
Growth rate = 12% of 1/12
Growth rate = 1%
Growth rate = 0.01
Thus,
Growth factor = 1 + r
Growth factor = 1 + 0.01
Growth factor = 1.01
Therefore, The growth factor will be 1.01.
