Please check explanations for answer to the question
Step-by-step explanation:
The exponential relation can generally be represented as ;
y = I (1 + x)^n
where I is the initial value
1 + x represents the growth rate
n represents the time such as number of years
y represents the value after n count
a) The value 1200 represents the initial count of bacteria in the study
b) 1.8 represents the growth rate of the bacteria population in the culture
c) 1000 represents the initial bacteria population in the second function
The difference mean that the initial population in the first case study is greater than what we have in the second function
where is the s in here though

Explanation:
Divide the figure into areas for which you have a surface area formula. Use the appropriate formula for each area, then add up the results.
Formulas are available for surface areas of a cone, cylinder, sphere, pyramid, rectangular prism, and for plane shapes that are circles, ellipses, triangles, rectangles, trapezoids, and regular polygons.
Most of the figures for which you are asked to find the area will decompose to some subset of these shapes. Take care to identify the relevant dimensions of each of the constituent parts of the area, and to make sure that all parts are accounted for. Do not allow your parts of the area to overlap, unless you intend to account for that overlap by subtracting the area that is counted more than once.
Also, use your common sense. A semicircle will have half the area of a circle, for example.
In some cases, it may be expedient to compute the area of a larger figure than the one you have, then subtract the part of that area that is missing from your figure.
Answer:
40 and 16
Step-by-step explanation:
Let's say these numbers are 5x and 2x.
Their sum is 56, so
5x + 2x = 56
7x = 56
x = 8
Now substitute the unknown value with 8.
5 · 8 = <u>40</u>,
2 · 8 = <u>16</u>
Answer:
Go for the 200 copies!
Step-by-step explanation:
Paying 77 times $0.39 is $30.03, which is more than the 200 copies offer, so even if you throw away all the copies you don't need, the 200 offer is still cheaper!
