The answer is A, 2,000 minus 23.75 is 1,976.25 and you divide that by 8 so it’s comes out to 247.03
The answers are
5(2x + 1)(3x - 2)
and
-5(-6x^2 + x +2) /
Hope this helps, trust me it's correct.
Answer:
Step-by-step explanation:
The root of a polynomial: the value of which x makes f(x) = a,x^n+a₂x^n-1+...+aₙx+aₙ⁺₁=0
Because the polynomial has exactly 3 roots, we know that f(x) = (x+a) (x+b) (x+c)
(-a,-b and -c are the 3 roots)
So its highest digit is 3.
Only 2x³ - x² - x + 4 corresponds to it.
Answer:
=-3 Stable
=-1 Instable
=1 Semistable
=2.5 Instable
Step-by-step explanation:
Equilibrium constant solutions (or critical points) occur whenever x′ = f(x) = 0
x′=−(x+3)(x+1)3(x−1)2(x−2.5)=0
=-3
=-1
=1
=2.5
we can see the plot of x′ = f(x) in the figure annexed. In order to analyse the stability of the constant solutions, we must see how the function changes around the constant solutions X's:
(i.) If f(x) < 0 on the left of X, and f(y) > 0 on the right of
X, then the equilibrium solution is unstable.
(ii.) If f(X) > 0 on the left of X, and f(y) < 0 on the right of
X, then the equilibrium solution y = c is stable.
(iii.) If f(x) > 0 on both sides of X, or f(x) < 0 on both
sides of c, then the equilibrium solution y = X is
semistable.
Then:
=-3 Stable
=-1 Instable
=1 Semistable
=2.5 Instable
You can figure this out by doing a proportion:
4.5 pages x pages
---------------- = ---------------
36 minutes 60 minutes(1 hr)
*makes sure that because they are giving you time in minutes that you convert the hour to minutes. also you need to always remember to line up the same factors like in this case line up the pages and the time.
36x = 4.5(60)
36x = 270
x = 270/36
x = 7.5 pages
hope this helps :)
