X=3
y=6
y=2x
2/3=2x
(2/3)/2=x
(2/3)×(1/2)=x
2/6=x
x=1/3
Answer:
there is one real solution
Step-by-step explanation:
use the quadratic formula. what is in the square root is called the discriminant.
since it came out to 0 there is one real solution
2.485 is round to 450 and 450 divide by 15 equals 30. 485 divide by 15 32 r 5
Use the given recursion and starting value of 
to find 
:
Do the same for 
and 
:
(That's not a mistake. This just tells you that the 2nd and 3rd iterates are very close together and have at least the same first 5 digits after the decimal.)
Weight of man and paint = 160 + 5 = 165 total pounds.
Gravitational force is independent of the path taken so we can ignore the radius of the silo.
Work done = total weight x height
The problem says he climbs to the top so overall height is 90 feet
Work = 165 lbs x 90 ft = 14,850 ft-lbs
