Answer:
Step-by-step explanation:
The average rate of change is defined as
In this case, b=2 and a =-3
Knowing this, we can input in our known values
Now we can find the values of and using the table
This gives us, which can be simplified to
Answer:
Step-by-step explanation:
What we want to fator is:
There is no common factor, but let's factor it by grouping. The first two addends can be factor as follows:
the second addends can be factor as well:
.
Then our original expression can be rewritten like
And here the is the common factor!
Finally, we can factor the quadratic expression as a difference of squares
Ant we get
now, we can extract the negative sign from , and we get
.
Answer:
or 10.29563
Step-by-step explanation:
Use the distance formula to determine the distance between the two points.
d = distance
= coordinates of the first point
= coordinates of the second point
Answer:
Kalpana = 49
Abhilasha = 77
Gouri = 16
Step-by-step explanation:
You can write this as an equation, where Kalpana is x, to make it easier to understand.
Gouri + 33 = x
Gouri = x - 33
Abhilasha - 28 = x
Abhilasha = x + 28
Now just plug in 49.
49 - 33 = 16
49 + 28 = 77
