Answer:
i'm not sure if this all correct
Step-by-step explanation:
part A you start at 8 from the first participant then you take away one from the last one. you add up all the numbers up to get the answer. 8+7+6+5+4+3+2+1=36.
part B the first part is 1x1x1x1x1x1x1x1=1. the second part is 8x7x6x5x4x3x2x1= 40,320. the third part is 1/40320
Answer:
a)
b)
Step-by-step explanation:
We are given in the question:
F(x,y,z) = (y, -x, z)
a)
We differentiate with respect to t.
b) F(c(t))
This is a composite function.
The rectangular one is 32 x 2 which is 64.
The square root of 64 is 8 so one side of the square garden plot is 8 meters. Hope this helped ;)
To evaluate the combination we proceed as follows:
21C3
Given nCk we shall have:
n!/[(n-k)!k!]
thus plugging the values in the expression we get:
21!/[(21-3)!3!]
=21!/(18!×3!)
=1330
Answer: 1330
Answer:
the answer is 1 because the power of any no. 0 is always 1
