What are the zeros of the polynomial function?

1 answer:

4 0

It won't be 0 because f(0) = 300

AS the last term is 300 the zeroes could possibly be 4 of the following possibilities +/-1 , +/-3 , +/- 10 ( The Rational Roots Theorem)

f(3) = 3^4 - 2(3)^3 - 103(3)^2 + 209(3) + 300 = 0

so 3 is one zero

f(10), f(-10) and f(-1) are also = zero

so the list is -10, -1, 3, 10 answer

F= 4m + 3 m – 1 make m the subject

PSYCHO15rus [73]

Answer:

m = $\frac{f+1}{7}$

Step-by-step explanation:

f = 4m + 3m -1

f = 7m - 1

Adding 1 to both sides

f+1 = 7m

Dividing both sides by 7

m = $\frac{f+1}{7}$

jenyasd209 [6]

Answer: 6%

Step-by-step explanation:

2/50 walk, that's the same as 4/100 or 4%

1/50 bike, that's the same as 2/100 or 2%

4/100 + 2/100 = 6/100 or 6%

What are the vertical asymptotes of the function f(x) =5x+5/x2 + x-2

katen-ka-za [31]

let's recall that the vertical asymptotes for a rational expression occur when the denominator is at 0, so let's zero out this one and check.

$\bf \cfrac{5x+5}{x^2+x-2}\qquad \stackrel{\textit{zeroing out the denominator}~\hfill }{x^2+x-2=0\implies (x+2)(x-1)=0}\implies \stackrel{\textit{vertical asymptotes}}{ \begin{cases} x=-2\\ x=1 \end{cases}}$

Select all that are equivalent to a^2/a^9 Assume a \= 0 1 1 DONE

Verdich [7]

0^2/0^9 = 0/0, therefore your answer is 1/1 considering that it is a fraction that is 100%, but if you divide 0 by 0, according to Keith’s theory you should have an endless number aka Infinity.
