A bacteria culture begins with eight bacteria which triple in size every week. how many bacteria exist in the culture after four

bija089 [108]

Well, you would have to multiply 8 by whatever factorial of 3, in this case 4 for the number of weeks
The equation is 8 x 3^4 which equals 648

My only thing is that they only triple in SIZE, and not multiply (as in make more of themselves) so technically speaking, there would still be 8 bacteria, just much bigger

3. A straight line passes through two points with

kirza4 [7]

Answer:

Step-by-step explanation:

Find the slope of the line

(x₁ , y₁) = (6 , 8) & (x₂ , y₂) = (0 , 5)

$Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{5-8}{0-6}\\\\=\frac{-3}{-6}\\\\=\frac{1}{2}$

m = 1/2 ;(x₁ , y₁) = (6 , 8)

y - y₁ = m(x - x₁)

$y - 8 = \frac{1}{2}(x - 6)\\\\y - 8 =\frac{1}{2}x -\frac{1}{2}*6\\\\y - 8 =\frac{1}{2}x- 3\\\\y = \frac{1}{2}x - 3 + 8\\\\y = \frac{1}{2}x + 5$
