A. Here's a fifth degree polynomial,
f(x) = x⁵ + 4x⁴ - 14x² + 9
It's in standard form, each term a constant coefficient times a whole number power of x (including the constant, which we can think of as the coefficient on x⁰=1), with the terms sorted from highest degree (highest power on x) to lowest.
B. The closure of addition wrt polynomials just means when we add two polynomials we get another polynomial.
f(x) = x⁵ + 4x⁴ - 14x² + 9
g(x) = -2x⁴ + x
f(x)+g(x) = x⁵ + 2x⁴ - 14x² + x + 9
We added two polynomials, we got another one, that's all closure is.
Answer:
77.5
Step-by-step explanation:
in this excercise the average is 4 months (January, Febuary, March, April)
the average rate is:
Answer:
28) Y=1x+c
29)-2/3x+c
Step-by-step explanation:
So x 2x are the sides using Pythagorean theorem x^2 + (2x)^2= 5x^2
So the side is the square root of 5x^2 so now we have the third side
The sum of the sides should add to 28 so:
X+2x+√5x=28 factor the x
X(3+√5)=28 and we know √5=2.236
So x= 28/5.236= 5.347
