Answer:
The rate of change of the area of the circle is approximately 
.
Step-by-step explanation:
Given:
radius 
We need to find the rate of change of the area of the circle at that instant.
Solution:
Now we know that;
Area of the circle is given by π times square of the radius.
framing in equation form we get;
to find the rate of change of the area of the circle at that instant we need to take the derivative on both side.
Substituting the given values we get;
Hence The rate of change of the area of the circle is approximately .
1/7 de catorce es dos, ahora Miriam tiene doce dólares restantes. 5/8 de 12 es 7.5, luego todos juntos, Miriam gastó nueve dólares.
Answer:
well, rounding to the nearest hundred is to the nearest hundred. For example, 151 rounded to the nearest hundred is 200, and 149 is 100.
Step-by-step explanation:
Answer:
y=-2x-3
Step-by-step explanation:
subtract 4x from both sides
4x-4x+2y=-6-4x=
2y=-6-4x
divide both sides by 2
-6/2 and -4x/2
simplify
hope this helps
Answer:
1. $29.4 million
2. 145.24
3. 145.24
4. 12.05
5. D. No, because the sample is not representative of the whole population.
Step-by-step explanation:
1. The computation of range of the sample data is shown below:-
Range of the sample data = Maximum value - Minimum value
= 42 - 12.6
= $29.4 million
2. For the computation of variance of the sample data first, we need to find out the mean which is shown below:-
Mean = 
= 24.83
The Variance of the sample data
= 
= 
= 145.24
3. The computation of the standard deviation of the sample data is shown below:-
The Standard deviation of the sample
= 
= $12.05155592
or
$12.05
4. No, as the sample does not represent the whole population.
