Answer: well the answer is 9
Step-by-step explanation:
Answer: c
Explanation: this is because the end behavior approaches negative infinity on the left side and positive infinity on the right side.
Answer:
92
Step-by-step explanation:
Multiplying two negatives together results in a positive.
-23 * -4 = 23 * 4 = 92
First, create a rule for this sequence.
Let a(1) be the first term (which here happens to be 1).
The next term, a(2), is twice the previous term, that is, twice 1, or 2.
a(3) = 2a(2) = 2(2) = 4
This is called a "recursive function."
The 3rd term is 4. The next, which is a(3) is 2*4, or 8.
Note that there's an alternative approach. The first term, a(1), is 1; the next is a(2) = a(1)*2^(2-1) = 1*2^1=2
the next is a(3) = 1*2^(3-1) = 1*2^2 = 4
So the rule is a(n) = a(1)*2^(n-1).
So a(8) is a(1)*2^(8-1) = 1*2^7 = 2^3*2^4 = 8(16) = 128
We have been given an image of a circle A, where BC || DE , mBC=58° and mDE=142°. We are asked to find the measure of angle CFE.
Since segment DC is parallel to segment DE, so measure of arc BD will be equal to arc CE.
We know that sum of all arcs of a circle is equal to 360 degrees. So we can set an equation as:
Since , so we will get:
Therefore, the measure of arc CE is 80 degrees.
We can see that angle CFE is inscribed angle of arc CE, so measure of angle CFE will be half the measure of arc CE.
Therefore, the measure of angle CFE is 40 degrees.
