How many lines of symmetry does the figure have?
11) Which answer choice is equivalent to this
n +n +n + n
C) n.
A)
4+n
(B) An
D) n(n + 3)
Answer:
4n = B
Step-by-step explanation:
N + N + N + N
Pretend that n is equaled to 2
2 + 2 + 2 + 2 is also equaled to 4 * 2 because there are four 2s.
It is just the same as n + n + n + n = 4 * n
4 * n is also written as 4n which is B.
Lets also look at the other answers.
A does not make sense because 4 + 2 (the example) does not make sense.
C does not make sense because exponents deals with multiplying n and not adding it
D does not make sense because you can already tell using the Distributive property that it is wrong
The answer is b, I hope this helps!

A water tank has a square base of area 5 square meters. Initially the tank contains 70 cubic meters. Water leaves the tank, starting at t=0, at the rate of 2 + 4 t cubic meters per hour. Here t is the time in hours. What is the depth of water remaining in the tank after 3 hours
Answer:
[tex]9.2\ \text{m}[/tex]
Step-by-step explanation:
[tex]b[/tex] = Surface area of base = 5 square meters
Volume of water in tank = 70 cubic meters
The rate at which the volume is reducing is
[tex]\dfrac{dV}{dt}=2+4t\\\Rightarrow dV=2+4tdt[/tex]
Integrating from [tex]t=0[/tex] to [tex]t=3[/tex]
[tex]V=\int^3_0(2+4t)dt\\\Rightarrow V=2t+2t^2|_0^3\\\Rightarrow V=2\times 3+2\times 3^2-0\\\Rightarrow V=24[/tex]
Volume of water remaining in the tank is [tex]70-24=46\ \text{m}^3[/tex]
Suface area of base [tex]\times[/tex] depth = Volume
[tex]5\times d=46\\\Rightarrow d=\dfrac{46}{5}\\\Rightarrow d=9.2\ \text{m}[/tex]
The depth of the water remaining in the tank is [tex]9.2\ \text{m}[/tex].
