A scientist has a culture of bacteria. The initial culture starts with 500 bacteria, and the number grows by 20% per hour, h. Which equation can be used to find the number of hours it takes for the number of bacteria to reach 1,000?
O 1,000 - 500(0.20)
O 1,000 - 500(1.20)
O 1,000 - 500 +0.20h
1,000 - 500+ 1.20%

answer: 25.4 units

step-by-step explanation: radius = 12.7 units

diameter = twice the radius

diameter = 12.7 x 2

= 25.4

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

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!
