Infinite! You can, for example, add -1 and 1 to the equation and make it equal. In x=5, you can have x=5+1-1. and it'd still be the same. To add on to it, you could do x+1-1=5+1-1, etc..

Jenny studied the characteristics of two species of bacteria. The number of bacteria of species A, A(t), after t hours is repres
Marina CMI [18]
<h3><u>Answer:</u></h3>

The function N(t) is given as:

N(t)=3+(0.25t)^3-8(1.06)^t

<h3><u>Step-by-step explanation:</u></h3>

Jenny studied the characteristics of two species of bacteria.

The number of bacteria of species A, A(t), after t hours is represented by the function:

A(t) = 5+(0.25t)^3

The number of bacteria of species B, B(t), after t hours is represented by the function:

B(t) = 2 + 8(1.06)^t

N(t) denotes the difference in the number of bacteria; hence N(t) is given by after t hours as:

N(t)=A(t)-B(t)

N(t)= 5+(0.25t)^3-(2 + 8(1.06)^t)

which on simplifying gives:

N(t)=5+(0.25t)^3-2-8(1.06)^t\\\\N(t)=5-2+(0.25t)^3-8(1.06)^t\\\\N(t)=3+(0.25t)^3-8(1.06)^t

Hence,

What area of the grass is being watered by this sprinkler
Novay_Z [31]
<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ Use this formula:

Area of circle = \pi r^{2}

However, as we are using 3.14 for 'pi', we can write it like this:

Area = (3.14)r^{2}

'r' is the radius which is 12ft

Substitute this value into the equation:

Area = (3.14)12^{2}

Solve:

Area = 452.16

Multiply this value by 0.75 to get the answer:

452.16 x 0.75 = 339.12

339.12 square feet is being watered

➶ Hope This Helps You!

➶ Good Luck (:

➶ Have A Great Day ^-^
