Answer:
its 24 permutations
Step-by-step explanation:

There are 24 different ways 4 students can be arranged in a row.
What is permutation?A permutation in math is the number of ways in which a set of data or objects can be ordered or arranged, where the order matters.
Given that, a family of 4 brothers are to be seated in a row at a theatre,
We need to determine the order of the possible seating arrangements,
we conclude that there are =
1! x 2! x 3! x 4! = 24
different ways 4 students can be arranged in a row,
Hence, there are 24 different ways 4 students can be arranged in a row.

What is the average rate of change from n = 3 to n = 4 for the sequence a, = 1(2)n - 1?
Answer:
Depends on what sequence it is. For geometric it's 7/5 and for arithmetic - 2
Step-by-step explanation:
For n = 3:
a, = 1*2*3 - 1 = 5
For n = 4:
a, = 8 - 1 = 7
These are the terms for n = 3 and n = 4 but the thing is, this could be both geometric sequence and arithmetic sequence, since you didn't specify, here are the possible answers:
For geometric sequence, the rate of change is equal to An / An-1 therefore:
r = 7 /5
For arithmetic sequence, it's equal to A2 - A1 = 7 - 5 = 2

Find the outer perimeter of this figure.
Round your answer to the nearest
hundredth. Use 3.14 to approximate.
Answer:
P = 28.66 ft
Step-by-step explanation:
So perimeter of half circle
= 2π × 6/2
= 2π × 4/2
= 8π ft/2
= 4 π
Total Perimeter = 6 ft + 8π/2 ft + 10 ft +
= 6 ft + 4 π ft + 10 ft
= 28.666 ft
Total Perimeter = 28.66 ft
PLEASE MARK ME AS BRAINLIEST AND HAVE A NICE DAY
Answer:
28.56
Step-by-step explanation:
The sides of the triangles are already given, so that will be 16. The diameter of the circle is given to be 8, so the radius will be half of it, 4. The circumference of a circle 2πr, so the circumference is 8π. we need to divide this by two because it is a semicircle, so the circumference of the semicircle is 4π. The answer should be 16+4π, and we can substitute in 3.14 for π to get 12.56+16=28.56
Hope this helps!
How do you do this question?
Problem 1
You are correct. The answer is choice C.A sequence is just a list of numbers where the order matters. Something like (1,2,3,4,5) is different from (3,1,2,5,4)
A series is where you add up that list of numbers to get a single value. For instance, the sum of the list (1,2,3) is 1+2+3 = 6. This is basically a partial sum when talking about infinite sequences because the next partial sum would be 1+2+3+4 = 10 and the next partial sum would be 1+2+3+4+5 = 15, and so on.
=======================================================
Problem 2
Answer: Choice AWhy is this? Each time we get a partial sum, we're basically forming a new sequence. We're forming a sequence of sums. Going back to the example in problem 1, we had the partial sums (6,10,15). If we keep this process going, we'll have the list of partial sums grow forever and not approach some finite value. Therefore, this series diverges.
If the sums were to slowly get closer to some fixed value, then we would say the series converges.

Find the measure of angle a.
a
50°
Answer:
the measure of angle is m(<a)=40
Step-by-step explanation:
the intirior angles of all triangles add up to 180
with this you can subtract the 90 degree angle and the 50 degree angle from the total of 180 degrees.
180
90
-50
---------
=40 degreese
hoped this helped.
Step-by-step explanation:
a+50+90=180°(being sum of angle of right angled▲)
or, a+140= 180°
or, a=180°_ 140°
Therefore, a=40°
The classical approach to probability requires that the outcomes are _______.
Answer:
equally likely
Step-by-step explanation:
The classical approach to probability requires that the outcomes are equally likely.
Equally likely means the chance or possibility of selection in the sample is equal for them. None is prioritized over the other, all has the equal chance of being selected in the sample.
Given that we are using the classical approach to probability which is based on an assumption that for any procedure having random set of possible outcomes, the possibility of each outcome is equal.
Thus, the classical approach to probability requires that the outcomes are equally likely.

y = sec(x) has a range of f(x) ≤ -1 and f(x) ≥ 1
Thus does not include zero in the range scale.
Extra's:
y = cos(x) has a range of -1 ≤ f(x) ≤ 1
y = cot(x) has infinity range
y = tan(x) has infinity range.
Answer:
sec x
Step-by-step explanation:
Let's set each function equal to zero to see if they have zero in their function.
If there is no solution, then we no solution of zero.
[tex] \cos(x) = 0[/tex]
[tex]x = \frac{\pi}{2} + 2\pi(n)[/tex]
So there is a solution of zero.
[tex] \cot(x) = 0[/tex]
[tex] \frac{ \cos(x) }{ \sin(x) } = 0[/tex]
There answer here is
[tex]x = \frac{\pi}{2} + 2\pi(n)[/tex]
So there is a solution. of zero here
If cot x=0, has a solution of zero, then tan x does as well. Since we can use
[tex] \frac{ \sin(x) }{ \cos(x) } = \tan(x) [/tex]
[tex] \frac{ \sin(x) }{ \cos(x) } = 0[/tex]
The answer here will be
[tex]0 + 2\pi(n)[/tex]
So that leaves sec x.
Proof:
[tex] \sec(x) = \frac{1}{ \cos(x) } [/tex]
1 divided by any number won't equal zero, so the solution will never be 0.

2k+8=0 Can someone help explain how to solves this please?
Answer:
2k + 8 = 0
2k + 8 - 8 = 0 - 8
2k = - 8
2k/2 = - 8/2
k = - 4
Step-by-step explanation:
you gotta put the 8 on the other side by subtracting and the divide both sides to get k
Answer:
k = -4
Step-by-step explanation:
2k + 8 = 0
Subtract 8 from both sides.
2k = -8
Divide both sides by 2.
k = -4
