Answer:
8 (C)
Step-by-step explanation:
The diagonals of a square are congruent and bisect each other.
One half of a diagonal = 4
Therefore, the whole diagonal is 8.
The is c
The explanation is that when you were working out
let's put value of t in equation.
x = 2√t
x = 2√y
x/2 = √y
(x/2)^2 = y
y = x^2 /4
now let's differentiate it with respect to x.
dy/dx = 2x/4 = x/2
differentiating again wrt to x
d^2y/dx^2 = 1/2
One person being nervous around strangers is assumed independent of other people behaviour. Then, the multiplication rule can be applied as
both nervous = 0.14*0.14 = 0.0196 = 1.96%
one is nervous, one is not nervous = 0.14*(1-0.14) = 0.1204 = 12.04%
At least one nervous = 1.96% + 12.04% = 14%
Answer:
Step-by-step explanation:
If 2in represented 17ft
Then 51ft will give (51×2)/17 in
= 6in
