Based on the scenario, the one that give the best practical interpretation would be :
D. the height of the water in tank , in inches, when the volume is 10 cubic inches
if the volume in terms of height then inverse V is in terms of volume
hope this helps

Answer:
5
Step-by-step explanation:
Lets recall what the pythagroens theorm is:
A^2+B^2=C^2. A and B are the side lengths(adjacent and opposite), while C is the longest sloped length(hyotenouse).
Lets plug in our values for each, and solve for the missing one:
12^3+b^2=13^2
Square each value(except for unknown):
144+b^2=169
Now get b alone(subtract 144 from both sides):
b^2=25
Now root both sides(removes the ^2):
b=5
This is your answer!
Hope this helps! :)
Use u subsitution the solve by grouping
u=x^2
u^3-16u=4u^2-64
u^3-4u^2-16u+64=0
(u^3-4u^2)+(-16u+64)=0
u^2(u-4)+(-16)(u-4)=0
(u^2-16)(u-4)=0
(u-4)(u+4)(u-4)=0
(u+4)(u-4)^2=0
u=x^2
(x^2+4)(x^2-4)^2=0
(x^2+4)((x-2)(x+2))^2=0
(x^2+4)(x-2)²(x+2)²=0
set to zero
x^2+4=0
x^2=-4
x=+/-2i
x-2=0
x=2
x+2=0
x=-2
the other roots are -2 and 2
