Answer:
<em>summation of five times negative three to the power of n from n equals zero to infinity</em>
Step-by-step explanation:
<u>Summation Notation
</u>
It represents the sum of a finite or infinite number of terms. Let's analyze the terms of the given succession:
5-15+45-135+...
If we take 5 as a common factor, we have
5(1-3+9-27+...)
The parentheses contain the alternate sum/subtraction of powers of 3. The odd terms are positive, the even terms are negative, thus the exponent must be n starting from 0 or n-1 starting from 1
The summation is then represented by
This corresponds with the option:
<u>summation of five times negative three to the power of n from n equals zero to infinity</u>
The measure of the angle ∠ABC is 110° and the measure of the reflex angle ∠CBD is 70°.
<h3>What is an angle?</h3>
Angle is the space between the line or the surface that meets. And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.
Linear angle - If the total of two angles is 180 degrees, they are said to be linear angles.
The measure of the angle ABC will be
∠ABC = 110°
The angle ∠ABC and ∠CBD are the linear angles. Then we have
∠ABC + ∠CBD = 180°
110° + ∠CBD = 180°
∠CBD = 70°

So basically it seems that you can just give any value to a and b as long as the statement given is true. 4 & 5 can work for the part of the problem.
a = 4; b = 5
Plugged in:
4 + 1 = 5 (b > a; 5 > 4)
Therefore the statement is true. This is proof that it is.
Part B is asking when can the statement be false and what numbers prove that if possible.
It is possible for there to be values for a and b in which the relationship given turns false. For example, a = 4 and b = 3 makes the statement false since 4 + 1 doesn't equal 3 and 3 is not greater than its a-value of 4.
Hope this helps!
