Answer:
The rate of change is ft^(2)/min
Step-by-step explanation:
The area of a circle is given by the following equation:
To solve this question, we have to realize the implicit differentiation in function of t. We have two variables, A and r. So
We have that:
.
We want to find
So
Since the area is in square feet, the rate of change is in ft^(2)/min.
So the rate of change is ft^(2)/min
Answer:
Step-by-step explanation:
Given
of child's age
Solving (1):
Determine the cost function.
Represent the years as y.
So, we have:
* y
Convert 25 cents to dollars.
So, we have:
The cost amount is then:
--- This is the cost function
Solving (b): Cost of 9 years old.
In this case;
Substitute 9 for y in
--- This is the cost for a child of 9
0.04 is 1/10 of 4 in the problem
Answer:
They may feel nervous because they are showing who they are as a person. Most people have a fake image of them selves when they are in public. For example If someone has a friend and they have done some things they do not want to share they might make a fake image of themselves to make it seem like they would have done those things.
This impacts their own self image because they are faking who they are and they feel that if they show someone who they truly are something bad might happen to their image and reputation and including everything they have built up in that fake image.
I hope this helps!
A:
When x=0, y is undefined. Hence A is wrong.
B:
When x=1, y=0. Thus, graph passes through (1,0) and B is correct.
C:
Plotting the graph gives us a shape consistent with an increasing function, so C is true.
D:
The graph contains values of y that are negative (y<0) so this is wrong.
E:
Graph is strictly increasing so this option is wrong.
F:
No, domain is x>0.
Correct options are B and C.
