Answer:
-1
Step-by-step explanation:
dy/dt = y² − 1 = (y + 1) (y − 1)
At t = 0, y = 0, and dy/dt = -1. Therefore, y is initially decreasing.
As y decreases, dy/dt increases. When y = -1, dy/dt = 0 and changes signs from negative to positive.
As y increases above -1, dy/dt again becomes negative. So y continues to approach -1 as t approaches infinity.
Given :
A water well rig has dug to a height , H = 60 feet after one full day of continuous use .
To Find :
If the height is currently 143.6 feet how time it been running .
Solution :
It is given that height after 24 hours of use is 60 feet .
So , height loose in 1 hours is :
Now , time taken to cover a height of 143.6 feet is :
Therefore , time taken is 57.44 hours .
Hence , this is the required solution .

- Find Area Of Rectangle That Measures 18 Feet Long And 15 Feet Wide
-----------------------------------
Area = Base · Height
Base - 15
Height - 18
- Insert Numbers Into Equation
15 · 18
15 · 18 = 270
270
Answer:
40%
Step-by-step explanation:
Original price = x
Sale = 20% off
20% / 100 = 0.2 to convert from a percent to a decimal
Sale = x - 20% of x = x - 0.2x = 0.8x
Sale price = y = 0.8x
Reduction of sale prices = 25% = 0.25
Reduction = y - 25% of y = y - 0.25y = 0.75y
End price in terms of original price (x):
0.75y = 0.75(0.8)x
= 0.6x
End price = 0.6 or 60% of original price, coming out to a 100-60 = 40% overall percentage reduction
Answer:
<u>Divide by -8</u> on both sides. <u>Flip</u> the inequality.
Step-by-step explanation:
You didn't provide any answer choices, but here's how you would solve this:
Notice that because we divided by a negative, the inequality sign must flip in the other direction!
