Answer:
X=55° Y=35°
Step-by-step explanation:
X+Y=90°
Y= x-20
(X-20)+X=90°
2X-20=90°
2X=110°
X=55°
55°+Y=90°
Y=35°

Consider the arithmetic sequence 10,12,14,16 if n is an integer, which of these functions generate the sequence?
Given:
The arithmetic sequence is:
10, 12, 14, 16, ...
To find:
The function that generates the given sequence if n is an integer.
Solution:
We have,
10, 12, 14, 16, ...
Here, the first term is 10 and the common difference is:
[tex]d=a_2-a_1[/tex]
[tex]d=12-10[/tex]
[tex]d=2[/tex]
The nth term of an arithmetic sequence is:
[tex]a_n=a+(n-1)d[/tex]
Where, a is the first term, d is the common difference and [tex]n\geq 1[/tex].
Putting [tex]a=10,d=2[/tex] in the above formula, we get
[tex]a_n=10+(n-1)2[/tex]
[tex]a_n=10+2n-2[/tex]
[tex]a_n=8+2n[/tex]
Therefore, the function [tex]a_n=8+2n, n\geq 1[/tex] generates the sequence.

Step-by-step explanation:
Jack can fill buckets of water four times fast as his sister Jill. They have to fill 400 buckets of
water for their village located at the bottom of a hill. Working together, Jack and Jill can complete
the job in six hours.
30. How many hours will it take Jack if he works alone?
Answer:
1.5 hour
Step-by-step explanation:
You divide 6 by 4.
Answer:
7.2 hrs
Step-by-step explanation:
Jack does 4/5 of the work in 6 hrs. He still needs to do 1/5 more if he's doing it by himself. 1/5 of 6 = 1.2 and 1.2 + 6 = 7.2 hrs

Step-by-step explanation:
find cot0 given cos0=2/7 and the terminal side is in quadrant IV
Answer:
0.2985
Step-by-step explanation:
find cot0 given cos0=2/7 and the terminal side is in quadrant IV
Given
cos theta = 2/7
theta = arccos(2/7)
theta = 73.40 degrees
cot theta = cot73.40
cot73.40 = 1/tan73.40
cot73.40 = 1/3.35
cot73.40 = 0.2985
hence the required answer is 0.2985

Use a permutation expression to solve.
In a race of 43 people, how many different ways can the runners place in 1st, 2nd, and 3rd?
Answer:
74046
Step-by-step explanation:
Permutations = [tex]_np_r=\frac{n!}{(n-r)!}[/tex]
where r = choice of things from a set ( in this case the 3 places ) so r = 3
and n = amount of things ( in this case the 43 people ) so n = 43
We then plug in the values of n and r in the permutations formula
[tex]\frac{43!}{(43-3)!} =74046[/tex]
Hence the answer is 74046

i drew the graph since i couldn’t write it out
Write the equation of the line in fully simplified slope-intercept form
Answer:
[tex]y=-\frac{3}{4} x+3[/tex]
Step-by-step explanation:
Slope-intercept form: [tex]y=mx+c[/tex]. where m is the slope of the line and c is where the line meets the y-axis.
From the graph:
[tex]c=3[/tex], we can clearly see that the line crosses the y-axis at (0,3)
Let's get two points from the graph to find m.
Point 1: (0,3)
Point 2: (4,0)
[tex]m = \frac{dy}{dx}[/tex], where dy is the difference in y and dx is the difference in x.
Therefore, we can put our points into that equation.
[tex]\frac{3-0}{0-4} = -\frac{3}{4}[/tex]
So, now we have m and c, we can rewrite the equation [tex]y=mx+c[/tex] with our values.
This gives us: [tex]y=-\frac{3}{4} x+3[/tex]

The picture is too big so you're not going to get the full explanation ok
I know the answer can someone just help me explain it???
Step-by-step explanation:
It is Graph B. We can do this by checking the points. The equation given is d = 5t^2, where d technically is the y-coordinate and t is the x-coordinate. On Graph B, two obvious points are (1, 5) and (2, 20). We can check these points to see if they fit the equation.
(1,5): d = 5t^2
5 = 5(1)^2
5 = 5*1
5 = 5, so this point is correct.
(2, 20): = d = 5t^2
20 = 5(2)^2
20 = 5*4
20 = 20, so this point is correct.
We know that Graph A is incorrect because it doesn't follow the equation. The line goes through (1, 5), which we already know is correct, (2, 10), (3, 15), and (4, 20). We already figured out that (2, 20) is correct so (2,10) can't be correct. (3, 15) and (4, 20) are also incorrect but in this case, we only need to find one incorrect coordinate to validate our answer. Thus, as Graph A is wrong, Graph B is right.
