Scientists can estimate the number of bacteria in a refrigerated food using the formula 0.26=

monitta

Time is C. 50 seconds

Step-by-step explanation:

The population of bacteria at time t here is given by

$0.2b=\frac{t^2}{20}$

where

b is the number of bacteria

t is the time in seconds

Here we want to find the approximate time at which the number of bacteria is

b = 625

Substituting into the equation and solving for t, we find:

$t^2=20\cdot 0.2 b\\t=\sqrt{4b}=\sqrt{4\cdot 625}=50 s$

Therefore, the solution is

C. 50 seconds

sergejj [24]

Y = 2x - 3 . . . (1)
y = -2x + 5 . . . (2)
Equating (1) and (2),
2x - 3 = -2x + 5
2x + 2x = 5 + 3
4x = 8
x = 8/4 = 2
x = 2
y = 2(2) - 3 = 4 - 3 = 1
y = 1

Solution = (2, 1)

Find the seventh term of the

jekas [21]

Answer:

$T_7 = \frac{64}{729}$

Step-by-step explanation:

Given

$a =1$

$r = \frac{2}{3}$

Required

Determine the 7th term

The nth term of a gp is:

$T_n = a * r^{n-1$

So, we have:

$T_7 = 1 * \frac{2}{3}^{7-1$

$T_7 = 1 * \frac{2}{3}^{6$

$T_7 = 1 * \frac{2^6}{3^6}$

$T_7 = 1 * \frac{64}{729}$

$T_7 = \frac{64}{729}$
