Step-by-step explanation:
10 red 6 blue so 16 altogether.
apologies if I'm wrong
The <em>correct answer</em> is:
P(x) = 13x² – 10x + 350; 1,102 fish
Explanation:
I plotted this data in a graphing calculator. The screenshot is attached. You can see the curve of the parabola in the graph. I then ran the quadratic regression; again, the screenshot is attached. It lists the values of a, b and c for the equation y = ax²+bx+c.
I<span>s that cos (2pi/3) or cos^2 (pi/3) ????</span><span>
1/2 of 2 =1
</span>cos (2pi/3) = - 1/2 <span>
cos (pi/3) = 1/2
cos^2 (pi/3) = 1/4
take your pick!
pi/3 radians = 60 degrees, and cos is looking for the side adjacent to the 60 degree angle
in a 30-60-90 triangle, the sides are in the ratio 1-sqrt(3)-2
so cos 60 = 1/2
2(pi/3) = 120 degrees-- the same triangle, except now, x is negative ==> cos 2pi/3 = -1/2</span>
Answer:
element remained after 14 minutes = = 7.091 g =~ 10 g
Step-by-step explanation:
After every minute the amount remained will be
(100 - 26.9 ) % i.e. 73.1 %
which is 0.731 times as much as the amount was at the start.
if the number of minutes passed is represented by t the function f(t) represents the mass of element remaining our equation will be
f(t) = 570( 0.731) ^ t
t= 14 minutes
f(14) = 570 ( 0.731) ^ 14
= 7.091 g =~ 10 g
