Answer:
Both the zoo-keepers are correct.
Step-by-step explanation:
The first zoo keeper uses the equation:
x - 41.5 = 13.5
⇒ x = 13.5 + 14. 5 = 55
Now, the second zoo- keeper uses the equation:
41.5 + 13.5 = x
⇒ x = 55
Both use x = 55.
Answer:
The absolute maximum and minimum is
Step-by-step explanation:
We first check the critical points on the interior of the domain using the
first derivative test.


The only solution to this system of equations is the point (0, 4), which lies in the domain.


is a saddle point.
Boundary points - 
Along boundary 





Values of f(x) at these points.

Therefore, the absolute maximum and minimum is
Let x be the first number each pair and y is the second of each
As you see 1x is 3y
And. 2x is 3*3y= 9y
3x = 3*3*3y= 27y
Last 4x =3*3*3*3y= 81y
So y = 3^x
Answer:
(-4, -7)
Step-by-step explanation:
21y=-147
y=-7
2x-5x(-7)=27
x=-4
