HELP WILL MARK BRAINLIEST IF RIGHT Colby and Jaquan are growing bacteria in an experiment in a laboratory. Colby starts with 50 bacteria in his culture and the number of bacteria doubles every 2 hours. Jaquan starts with 80 different type of bacteria that doubles every 3 hours. Let x equal the number of days.
Colby's experiment follows the model:
y=50·2^x
y=50·2^8x
y=50·2^12x
Jaquan's experiment follows the model:
y=80·2^x
y=80·2^8x
y=80·2^12x

answer: it would most likely be y=6 and 5/7.

step-by-step explanation:

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
