Answer:18x+5
Step-by-step explanation:
Answer: 15 rpm
Step-by-step explanation:
D is the correct answer. To find this, take the total number, 25 and multiply it by 19% to get 21, which is the number of hard copies.
Answer:
6x^8y^5
Step-by-step explanation:
Combine the like terms. 3 x 2 is 6. x^2 x x^6 is x^8, because you add the exponents of similar bases. Finally, y^4 x y is y^5.
I find it useful to use a graphing calculator to find the zeros of higher-order polynomials. Once you find one or more rational zeros, you can factor them out to find the reduced polynomial factors (or you can use synthetic division).
1. This factors as (5x+2)(3x-1)(x-8). Roots are {-2/5, 1/3, 8}
2. This factors as (x-9)(x²-5x+2). Roots are {2.5-√4.25, 2.5+√4.25, 9}
3. This factors as (x-6)(5x²+3x+1). Roots are{-0.3-i√0.11, -0.3+i√0.11, 6}
