Answer:
The common difference is 1.5
Use the explicit formula to find a1.
a1 = 1.2
What is the explicit formula for the arithmetic sequence?
= 1.2 + (n - 1)1.5
Step-by-step explanation:
Answer: There are 720 ways to do so.
Step-by-step explanation:
Since we have given that
Number of spaces in a flagpole = 10
Number of types of flag = 3
Number of spaces for red flag = 1
Number of spaces for green flag = 1
Number of spaces for blue flag = 1
We will use "Fundamental theorem of counting":
So, Number of ways that the 10 spaces of the flagpole can be covered with flags such that no spaces is empty is given by
Hence, there are 720 ways to do so.
<u>Answer:</u>
<u>Step-by-step explanation:</u>
We are given the following expression and we are to evaluate it when the value of a is 10 and b is -9:
Substituting the given values in the above expression to get:
Therefore, the simplified form of the given expression that we get after evaluating it when a is 10 and b is -9 is .
Answer:
Step-by-step explanation:
The equation of the circle has the following form
The equation of the circle has the following form
We know that the circle goes through the following points
(0, 0)
(6, 0)
(0, -8).
Then we substitute the values of x and y in the equation
<u>For (0, 0)</u>
<u>For (6, 0)</u>
<u>For (0, -8)</u>
Finally the equation is:
