Here we are given how much work is done in a fix time interval
then they ask to find the rate of doing the work .
in such problem we can find the rate of doing a work by using the formula :
amount of work done
--------------------------------------------------- = work done in unit time
Time taken to do that amount of work
In 40 minutes number of pages she reads = 50
In 1 minutes number of pages she would be reading = 50 /40
= 5/4 page
Answer 5/4 page .
Answer:
1 2 4 6. Tell me if im wrong.
Step-by-step explanation:
The subject area of probability is actually expressed as a fraction or percentage because it represents a part of a whole. In lay man's term, probability is the scientific study of chance, likeliness and odds of an event happening. For example, you want to find the odds of getting a heads in a toss of the coin. You know that there are 2 possible results: head and tails. So, the probability of getting a head is 1/2 or 50%. Since it is a part of a whole, the probability in fraction should never be an improper fraction. This is the type of fraction in which the numerator is greater than the denominator. This is impossible as a probability because it will never exceed 1.
First, get rid of the parenthesis:
5x-4=5x-15+11
5x-4=5x-4
this equation will always be true, so there are infinite number of solutions.
Answer:
Analyzed and Sketched.
Step-by-step explanation:
We are given 
.
We need to find the following to sketch the graph.
1) First derivative of y with respect to x to determine the interval where function increases and decreases.
2) Second derivative of y with respect to x to determine the interval where function is concave up and concave down.
The roots are x = -1/2 and x = 1/2 but negative one cannot be possible due to logarithmic function.
x = 1/2 is absolute maximum.
So, concavity is always down.
Here, x = 0 is vertical asymptote.
I attached the picture of sketched graph.
