Answer:
0.25
Step-by-step explanation:
simplify 4/16 to 1/4.
multiply 1/4 by 25/25.
then you get 25/100, which equals to 0.25
A constant function is a horizontal line.

<u>Answer:</u>
The correct answer option is 
.
<u>Step-by-step explanation:</u>
We are given the following expression and we are to evaluate it when 
and 
:
![[\frac{3^2a^{-2}}{3a^{-1}} ]^k](https://tex.z-dn.net/?f=%5B%5Cfrac%7B3%5E2a%5E%7B-2%7D%7D%7B3a%5E%7B-1%7D%7D%20%5D%5Ek)
Substituting the given values of 
and 
to get:
![[\frac{3^2(5)^{-2}}{3(5)^{-1}} ]^{-2}](https://tex.z-dn.net/?f=%5B%5Cfrac%7B3%5E2%285%29%5E%7B-2%7D%7D%7B3%285%29%5E%7B-1%7D%7D%20%5D%5E%7B-2%7D)
Answer:
A. 4
B. 1
Step-by-step explanation:
The degree of a one-variable polynomial is the largest exponent of the variable.
__
<h3>A.</h3>
For f(x) = x^4 -3x^2 +2 and g(x) = 2x^4 -6x^2 +2x -1, the sum f(x) +a·g(x) will be ...
(x^4 -3x^2 +2) +a(2x^4 -6x^2 +2x -1)
= (1 +2a)x^4 +(-3-6a)x^2 +2ax -a
The term with the largest exponent is (1 +2a)x^4, which has degree 4. This term will be non-zero for a ≠ -1/2.
The largest possible degree of f+ag is 4.
__
<h3>B.</h3>
The polynomial sum is ...
f+bg = (1 +2b)x^4 +(-3-6b)x^2 +2bx -b
When b = -1/2, the first two terms disappear and the sum becomes ...
f+bg = -x +1/2 . . . . . . a polynomial of degree 1
The smallest possible degree of f+bg is 1.
