In Polynomials all the exponents of x-variable must be positive integers, then polynomials are: <span>a) -x^5+7x-1/2x^2+9, the exponents of x's are: 5, 1, and 2 b) x^3-4x-3, the exponents of x's are: 3, and 1 f) x^4+x^3√7+2x^2-√3/2x+π, the exponents of x's are: 4, 3, 2, and 1
Not polynomials are: </span><span>c) 4 / x^2-4x+3 = 4x^(-2)-4x+3, the exponents of x's are -2, and 1 d) x^4+5/x^3-√x+8=x^4+5x^(-3)-x^(1/2)+8, the exponents of x's are 4, -3, and 1/2 e) </span>|x|^2+4√x-2=<span>|x|^2+4x^(1/2)-2, the exponents of x's are 2 and 1/2</span>
The proportion of the secret blend is 90/27. When there is only 40 pounds of gazebo, your proportion looks like this: 40/X. X being pounds of Kona. When you are to simplify 90/27 you're left with 10/3. Cross multiply 10/3 and 40/X to and simply to get 10x = 120, leaving you with 12 as your final answer. Hope this explanation helps.
