Answer:
Yes
Step-by-step explanation:
If , then .
If are positive, then .
So if I multiply both sides of by it will not effect the direction of the inequality since it is of positive value.
This actions gives us .
Using foil we can multiply the left hand side out resulting in:
Add on both sides:
.

Also consider the function . This function increases after is 0. This means as you increase the value for the value for increases for positive value inputs of .
Answer:
6 feet
Step-by-step explanation:
Consider the right triangle formed by the wall, ladder and ground.
Let the distance the ladder is from the wall be d , then
Using Pythagoras' identity in the right triangle
The square on the hypotenuse ( ladder) is equal to the sum of the squares on the other 2 sides ( wall and d ), then
d² + 8² = 10²
d² + 64 = 100 ( subtract 64 from both sides )
d² = 36 ( take the square root of both sides )
d = = 6
That is the ladder is 6 feet away from the wall
Are you asking for definition because if so i believe what you’re looking for is absolute value

Answer:
74.958 lb-in
Step-by-step explanation:
We are given that
Natural length of spring=l=6 in
After stretching, the length of spring=8.3 in
Weight=W=9 lb
Extension in the sprig=8.3-6=2.3 in
By hook's law
Using the formula
Extension in the spring when the length of spring after stretching to 12.2 in=12.2-6=6.2 in
Work done, W=
