Answer:
y4 - 8y3 + 8y2 + 2y + 8
—————————————
2y2
Step-by-step explanation:
Step 1 :
4
Simplify ——
y2
Equation at the end of step 1 :
y y 4
(((((y2)+————)-((2•—)•y))+——)-4y)+4
(y2) 4 y2
Step 2 :
y
Simplify —
4
Equation at the end of step 2 :
y y 4
(((((y2)+————)-((2•—)•y))+——)-4y)+4
(y2) 4 y2
Step 3 :
y
Simplify ——
y2
Dividing exponential expressions :
3.1 y1 divided by y2 = y(1 - 2) = y(-1) = 1/y1 = 1/y
Equation at the end of step 3 :
1 y2 4
(((((y2)+—)-——)+——)-4y)+4
y 2 y2

Answer:
120 miles in 4.8 hours
75 miles in 5 hours
Step-by-step explanation:
Ship:
The number f(x) of miles a ship is from its destination x hours after starting a voyage is given by f(x) = 120 - 25x. This means, initially the ship is 120 miles away from its destination.
If the ship traveled 120 miles, then f(x)=0 (the ship will be 0 miles away from its destination) and
0 = 120 - 25x
25x = 120
x = 4.8 hours.
Submarine:
At x = 0 hours the submarine was 75 miles away
At x = 5 hours, the submarine was 0 miles away.
So, in 5 hours the submarine traveled 75 miles
