Answer: a=x, then polynomial is zero.
a = x - 1/(x^2+x-1), then polynomial is one, but we have to note (x^2+x-1) != 0.
Step-by-step explanation:
The polynomial product is identically zero when a = x, since factor (x-a) becomes zero. Another way for a polynomial to not contain x is if it is a constant not zero. For example,
(x-a) = 1/(x^2+x-1)
a = x - 1/(x^2+x-1)
Substitute a = x - 1/(x^2+x-1) into
(x^2+x-1)(x-a) = (x^2+x-1)/(x^2+x-1) = 1.
Answer:
184 cm³
Step-by-step explanation:
Volume= base*height
V= 20 cm²*9.2 cm= 184 cm³
Answer: Hello mate!
We know that out of 3000 people, 9 had a alergic reaction.
in this case our 100% is 3000, and we want to know what percentage is equivalent to those 9 that had a mild allergic reaction.
here we can use the rule of 3, this is:
if 3000 is equivalent to 100%, then 9 is equivalent to:
(9/3000)*100% = 0.3%
The slope can be found with
m = y2 - y1 So -11 is y2, -6 is y1 | x2 is 2, x1 is -6
---------
x2 - x1
m = -11 - (-6)
--------- = -5 / -5 = -1
2 - 7
slope is -1
Answer:
20
Step-by-step explanation:
mean is average
add all numbers get 160
divide by number of numbers (8) and get 20
