it is an irrational not sure but i don't believe that it could be put in an ratio, so I say an irrational number
Answer:
2 sqrt(13)
Step-by-step explanation:
We can use the Pythagorean theorem
The x value between A and B is 4 units and the y value is 6 units
The distance is
d = sqrt( x^2 + y^2)
= sqrt( 4^2 + 6^2)
= sqrt( 16+36)
= sqrt(52)
= sqrt(4*13)
= 2 sqrt(13)
43+35=78 the answer is 78
Instead of x im going to use the letter b, so it isnt confused with the times symbol
the volume is Length x height x width = Volume
(6) x (b) x (0.3 - 2b) = V
1.8b - 12b^2 = V
the first derivative of V with respect to b is
dV/db = 1.8 - 24b
this is at a maximum (or possibly minimum) when its first derivative is equal to zero
0 = 1.8 - 24b
solving for b
b = 1.8/24 = 0.075m or 7.5 cm
Answer:
-16
hope this helps
