the answer is B: (-4,2)
Answer:
37.6
Step-by-step explanation:
A to B - just count up the numbers, it's 10
B to C - just count up the numbers, it's 12
A to C - Now this is a right triangle, so use the Pythagorean theorem(10^2 + 12^2 = 244, and take the square root of that, which is 15.62 and round to 15.6
And just add them together 10+12+15.6 to get 37.6
Answer:
The distance between points 8 and -5 is 13
Step-by-step explanation:
We need to find distance between points 8 and -5
The formula used to find the distance is:
Absolute value is used to get only positive values. i.e |-1|=1 if required.
We are given: b=8 and a=-5
Putting values and finding distance
So, the distance between points 8 and -5 is 13
X+1 is the answer for this question
<span>Category Number of Choices
Economics 5 - 3 = 2
Mathematics 4
Education 3
Sociology 2
Since out of 5 sections in Economics 3 are full, there are only 2 remaining sections available for Jessica to choose from.
I think this is a combination:
n = 2 + 4 + 3 + 2 = 11
r = 1 + 1 + 1 + 1 = 4
nCr = n! / r!(n-r)! = 11! / 4!(11-4)! = 11! / 4! * 7! = 330
Jessica can have 330 different sets of classes to take.
