Answer:
-3
Step-by-step explanation:
g(1) = -3x² + x - 1
= -3() + 1 -1
= -3(1) + 1 - 1
= -3 +1 -1
g(1) = -3
Just put the 1 everywhere you see an x.

Answer:
a) 4800 bacteria
b)
c) 754 bacteria
Step-by-step explanation:
A bacteria culture starts with 300 bacteria and doubles in size every half hour.
This means that the number of bacteria after t periods of half hour is given by:
(a) How many bacteria are there after 2 hours?
2 hours is 2*60/30 = 4 periods of 2 hours, so this is y(4).
(b) How many bacteria are there after t hours?
It doubles every half hour, so each hour, it is multiplied by 4. Then
(c) How many bacteria are there after 40 minutes?
40 minutes is 40/30 = 1.33 periods of half hour. So this is y(1.33).
The standard form of a circle is:
(x-h)^2+(y-k)^2=r^2, where (h,k) is the (x,y) coordinate of the center of the circle and r is its radius. In this case:
(h,k) is (1,5) and it has a radius of √4 which is 2
So the center is the point (1,5) and it has a radius of 2.
