Answer:
The 75th term of the arithmetic sequence -17, -13, -9.... is:
Step-by-step explanation:
Given the sequence
An arithmetic sequence has a constant difference 'd' and is defined by
computing the differences of all the adjacent terms
The difference between all the adjacent terms is the same and equal to
The first element of the sequence is:
now substitute and in the nth term of the sequence
Now, substitute n = 75 in the sequence to determine the 75th sequence
Therefore, the 75th term of the arithmetic sequence -17, -13, -9.... is:
Simple...if you want to solve this.....
49-7x=21
Isolate the variable (x)
49-7x=21
-49 -49
-7x=-28
Now, simplify...
x=4
Thus, your answer.
The area of a whole circle is (pi) (radius²) .
So the area of half of it would be <em>(1/2) (pi) (radius²) .</em>
If you don't know the radius, then you can use the formula
Area = (1/8) (pi) (diameter²) .
Answer:
x = -3
Step-by-step explanation:
Notice that the addition of angle <CDH plus angle <HDE have to give the measure of angle <CDE (which is 144 degrees as stated in the problem)
Then, we can say in equation form:
<CDH + <HDE = 144
replacing with their expressions in terms of x:
x + 93 + 57 + x = 144
solving for x:
2 x + 150 = 144
2 x = 144 - 150
2 x = - 6
x = -3
