Step-by-step explanation:
explain all steps to prove or disprove.
A(-5,0) B(5,0)
Answer:
A
Step-by-step explanation:
Here, we want to find the value of ln (-7)
ln is same as Log to base e and mathematically , we have it for positive numbers only
For that of negative numbers, we get undefined results
However, by the use of special mathematical
methods, we have the answer for ln (-7) as;
1.94591015 + 3.14159265 i
As we can see, for the second part, the value for the coefficient of the complex number is pi and thus, we have the correct option as A
Answer:
Step-by-step explanation:
1)
2(x – 4) + 32
Multiply it out.
2 * x - 2 * 4 + 32
2x - 8 + 32
2x + 24
2)
9x + 4(x + 2) – 5
Multiply it out
9x + 4 * x + 4 * 2 - 5
9x + 4x + 8 - 5
13x + 3
None. The triangle inequality states that the sum of the smaller two sides of a triangle must be greater than the third side. As 4+5=9, this inequality is false in this case, so these sides cannot create a triangle.
Answer:
Given
This is our initial premise.
2) Linear pairs of angles are supplementary
This one is a little questionable, as some definitions of linear pairs require supplementary angles, whereas others only require the intersection of two lines. Check your book or notes for any given theorems regarding supplementary angles.
3)

The definition of supplementary angles is that two angles are supplementary if their measures sum to

.
4) Substitution of 1. into 3.
As with 2), this may differ based on the teacher or book. Some may prefer that you write out the equation, whereas others may be satisfied with the references as given. Check for similar examples.
