The first answer is 0.38(x^2)-2.45x+5.1. first, on a graphing calculator, you enter the data in the chart into stat edit. then you turn on stat plot 1 and press graph. press stat calc quadreg to find the equation. then, substitute 9 in for x to find that there will be 13.83 thousand bacteria after 9 hours
Answer:
33/40
Step-by-step explanation:
Find a common multiple or multiply each denominator so 1/5 *8 is 8/40 and 5/8*5 is 25/40, add them together to get 33/40 and simplify
As you can see, this is a multiplication root.
y = 4 · x
x = 7 · 3
So solve for x first to solve for y.
x = 7 × 3
x = 21
y = 4 · x
y = 4 × (21)
y = 84
We have cos( x - y ) = cosxcoy + sinxsiny <=> cos ( π - x ) = cosπcosx + sinπsinx <=> cos ( π - x ) = (-1)cosx + 0sinx = -cosx;
