Answer:
If there are 5 persons and at a time only 3 can be arranged, the total number of arrangements is 60
Option C is correct
Step-by-step explanation:
There are 5 persons and at a time only 3 can be arranged.
The total number of arrangements = nPr = n!/(n-r)!
Here n = 5 and r = 3
nPr = n!/(n-r)!
nPr = 5!(5-3)!
nPr = 5!/2!
nPr = 5*4*3*2!/2!
nPr = 5*4*3
nPr = 60
So, if there are 5 persons and at a time only 3 can be arranged, the total number of arrangements is 60
Option C is correct.
Answer:
5 1/2 miles per 1 hr
Step-by-step explanation:
biked 1 3/8 miles in 1/ of an hour
1 3/8 miles = 11/8 miles in 1/4 of hour
11/8 miles divided by 1/4 hr
11/8 ÷ 1/4
11/8 * 4/1 =44/8 = 5 4/8 miles in 1 hr or 5 1/2 miles per 1 hr
Answer: (y - 3) = 7/6 (x - 4)
Step-by-step explanation:
The formula for point slope form is (y-y₁) = m(x-x₁)
Parallel lines will always have the same slope, so the slope of the new line is still 7/6.
The line goes through point (4, 3),
so x₁ = 4, and y₁ = 3 as points are written as (x, y).
The Answer to this Question is:
(2x^2+3y)(4x^4-6x^2y+9y^2)
This symbol ^ means that the number after is an exponent.
