You gotta post the choices, but I'm guessing it's
So you would start with 40/n because quotient means division and then it would be (40/n) - 13 (40 divided by n then minus 13) because the answer is thirteen less than the quotient of those numbers. since it wants you to evaluate for n=2 you would do 40/2 which is 20 then subtract 13 which is 7.
So write the expression as (40/n) -13 and when you evaluate just stick the 2 where the n is for (40/2) - 13
20 - 13
= 7
Answer:
sqrt(5)
Step-by-step explanation:
I hope this helps
Let x = length of side of the square. Then area of the square is
A(x) = x^2
You are also told that dx/dt = 6 cm/s
Now, you want to find dA/dt when A = 16, i.e., when x = 4.
Since
dx/dt = 6cm/s
and
dA/dx = 16cm/s
dA/dx dx/dt
= dA/dt
dA/dt A' = 2xx'
A' = 2x6cm/s
So we need to solve for x because we are trying to find dA
<span>so
</span>16 = x^(2)
(16)^(1/2) = 4
<span>thus

A' = 2(4)(6)
A' = 48
speed of car = 22m/s
since body is travelling in opposite direction.
Relative velocity = sum of velocity of two bodies
ie 22m/s + 22m/s
44m/s.s
