Answer:
3cm/s
Step-by-step explanation:
Area of a square is expressed as:
A = L²
Rate of change of area is expressed as:
dA/dt = dA/dL•dL/dt
Given that
dA/dt = 24cm²/s
L = 4cm
Required
dL/dt
Since dA/dl = 2L
dA/dl = 2(4)
dA/dl = 8cm
Subatitute the given values into the formula
24 = 8 dL/dt
dL/dt = 24/8
dL/dt = 3cm/s
Answer:
D) x=5, x=-5.
Step-by-step explanation:
x^2-25=0
factor
(x+5)(x-5)=0
x+5=0, x-5=0,
x=0-5=-5,
x=0+5=5.
<h2>
Answer:</h2>
Option: A is the correct answer.
A. negative 5 over 8 minus negative 2 over 8 = negative 3 over 8; therefore, the distance from A to B is absolute value of negative 3 over 8 equals 3 over 8 units.
<h2>
Step-by-step explanation:</h2>
The location of Point A is : A(-5/8)
and Point B is located at : B(-2/8)
We know that when two points lie over a number line then the distance between the two points is the absolute difference between the two points.
If A is located at a.
and B is located at b.
Then the distance between A and B is given by:
|a-b|
Hence, here the distance between A and B is given by:

Answer:
Its B
