Answer:
No, because <em>x</em> has multiple values for <em>y</em>.
Step-by-step explanation:
Any input into a function has to map into exactly one output. The input, <em>x</em>, has multiple values for <em>y</em>. Therefore, it is not a function.
I belive your answer is 3
Answer:
<em>The capacity of the cistern is</em>
<em>The volume of iron used is</em>
Step-by-step explanation:
<u>Volume</u>
The volume of a rectangular box of dimensions x,y,z is given by:
V = x.y.z
The external dimensions of the rectangular cistern are 1.35 m, 1.08 m, and 0.90 m, thus the external volume is:
The cistern is made of iron 2.5 cm= 0.025 thick, thus the internal dimensions are:
1.35 - 0.025 = 1.325 m
1.08 - 0.025 = 1.055 m
0.90 - 0.025 = 0.875 m
The internal volume is:
The capacity of the cistern is 1.2231~m^3
The volume of iron used is the difference between the external and the internal volumes:
The volume of iron used is
5^2 + x^2=8^2
25+x^2=64
X=6.2
