Answer:

(3x + 5)/2 = 7

Step-by-step explanation:

If you substitute 3 for x, you get the equation:

(3(3) + 5)/2 = 7

(9 + 5)/2 = 7

14/2 = 7

Answer: Infinite

Step-by-step explanation:

well a lot things can equal x=3

There are many examples so 2x=4x-6 or 3x=4x-3 or 1000x=2000x-3000 would all equal to x=3

Suppose that the number of bacteria in a certain population increases according to an exponential growth model. A sample of 2600

melisa1 [442]

Answer: There is 3.994% continuous growth rate per hour.

Step-by-step explanation:

Since we have given that

Initial bacteria = 2600

After two and a half hours,

Number of bacteria = 2873

We need to find the continuous growth rate per hour.

As we know the equation for continuous growth rate per hour.

$y=y_0e^{rt}\\\\2873=2600e^{2.5r}\\\\\dfrac{2873}{2600}=e^{2.5r}\\\\1.105=e^{2.5r}\\\\\text{Taking log on both the sides}\\\\\ln 1.105=2.5r\\\\0.0998=2.5r\\\\r=\dfac{0.0998}{2.5}\\\\r=0.0399\times 100\\\\r=3.994\%$

Hence, there is 3.994% continuous growth rate per hour.
