Step-by-step explanation:
Base on my research there are ways to get the number of roots. If you are looking for negative roots and even the positive one has their own ways. But in this problem, we just need to determine the total number of roots of a polynomial. In determining the total number of roots, you just need to find the degree of the polynomial function. The degree refers to the highest exponent of the polynomial. Therefore, in the function given, 6 is the degree of the polynomial function. The total number of roots is 6.
<u>Answer:</u>
29 years
<u>Step-by-step explanation:</u>
- Given the function
, where x stands for the number of years since the material was put into the vault, we can plug 140 into x to find the amount leftover. - Another way of doing this is to change the function to
which are equivalent functions, and then plug 140 into x. This function is helpful if you also needed to find the rate. - I'll use the 1st function because the question doesn't ask for the rate
From here I'll just use a calculator & get 28.7, or 29 years.
Answer: C and D
Explanation:
Is it A? No, because a right triangle does not have all three sides with equal length. Only in a equilateral triangle will have all three equal sides of equal length.
Is it B? No, because a triangle has ZERO parallel lines. Remember parallel lines are like this | | in a triangle the lines are like this /\
Is it C? Yes, because a triangle has two sides of equal length, meaning it has two congruent sides.
Is it D? Yes, a right triangle has two sides that create the 90 degrees making it a right triangle. Perpendicular means that theirs two lines creating the 90 degree and a triangle has two perpendicular sides.
Answer:
i think the answer is, A...
