Given that (-4,3) and (6,-3) are opposites points on the circle (i.e diameter) write the equation of the circle

Answers

The center of the circle is the midpoint of the points or ((-4+6)/2,(-3+3)/2)=(1,0). Now, the diameter is the distance between the points. Using distance formulas (or noticing that the y-values are the same so it is a horizontal line), the distance is 10. Therefore, the radius is 5. The equation of a circle is (x-a)^2+(y-b)^2=r^2 where (a,b) is the center. Therefore, the equation is (x-1)^2+(y-0)^2=5^2.

How many ways are there to select a committee to develop a discrete mathematics course at a school if the committee is to consist of 3 faculty members from the mathematics department and 4 from the computer science department, if there are 9 faculty members of the math department and 11 of the CS department?

Answers

Answer:

There are 27,720 ways to select the committee

Step-by-step explanation:

First, it is necessary to know how many ways are there to select 3 members, if there are 9 members of the mathematics department. This can be found using the following equation:

$nCk=(n!)/(k!(n-k)!)$

Where nCk gives as the number of ways in which we can select k elements from a group of n elements. So, replacing n by 9 and k by 3 members, we get:

$9C3=(9!)/(3!(9-3)!)=84$

So, there are 84 ways to select 3 members from 9 members of the mathematics department.

At the same way, we can calculate that there are 330 ways to select 4 members from the 11 that belong to the Computer science department as:

$11C4=(11!)/(4!(11-4)!)=330$

Finally the total number of ways in which we can form a committee with 3 faculty members from mathematics and 4 from the computer science department is calculated as:

9C3 * 11C4 = 84 * 330 = 27,720

What equation represents the slope intercept from the line below y intercept ( 0, 2) slope -3/7 ( PLEASE HELP FAST TOP ANSWER GETS BRAINLIEST!!)

Answers

Answer:

$\boxed{Option \ A}$

Step-by-step explanation:

y-intercept = b = 2 [y-intercept is when x = 0]

Slope = m = -3/7

Putting this in slope-intercept equation

=> $y = mx+b$

=> $y = -(3)/(7)x + 2$

what is the ratio of 9:45, 19:38, 24:40, 14:28, 8:20, 15:20, 9:15, 19:180, 18:27, 36:60, 12:30, 32:54, 13:65, 15:30, 12:15, 12:20.

Answers

9 : 45 = 3 : 15 = 1 : 5
19 : 38 = 1 : 2
24 : 40 = 12 : 20 = 6 : 10 = 3 : 5
14 : 28 = 1 : 2
8 : 20 = 4 : 10 = 2 : 5
15 : 20 = 3 : 4
9 : 15 = 3 : 5
19 : 180 = 19 : 180
18 : 27 = 6 : 9 = 2 : 3
36 : 60 = 18 : 30 = 9 : 15 = 3 : 5
12 : 30 = 4 : 10 = 2 : 5
32 : 54 = 16 : 27
13 : 65 = 1 : 5
12 : 15 = 4 : 5
12 : 20 = 6 : 10 = 3 : 5
