124 sq in...................
Answer:
-8 - 36i
Step-by-step explanation:
To simplify 7C4 we use the combination formula given by:
nCr=n!/[(n-r)!r!]
thus:
In our case we shall have:
n=7 and r=4
7C4
=7!/[(7-4)!4!]
=5040/[6×24]
=5040/144
=35
The answer is 35
Answer:
15 Kg cm²
Step-by-step explanation:
Given that V varies inversely with P then the equation relating them is
V =
← k is the constant of variation
To find k use the condition
V = 360, P = 20, then
360 =
( multiply both sides by 20 )
k = 7200
V =
← equation of variation
When V = 480, then
480 =
( multiply both sides by P )
480P = 7200 ( divide both sides by 480 )
P = 15
