Two angles x and y are complementary - which means their
angles add up to 90 degrees. Angle y is 20 degrees less
than angle x. Find the measure of each angle.

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]

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

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

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:

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.

Step-by-step explanation:

Answer:

93

Step-by-step explanation:

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.
