The area of the square is 9 square inches.
The area of the circle is about 7.065. As a result, the area of the shading region is 1.94 square inches. Hope it help!
A small bottle costs $14.
To solve the problem, the equation would be this:

Let <em>s </em>represent a small bottle. Since one large bottle is $4 more than a small one, you would write out <em>(4+s)</em>. Then, multiply it by 8 to find one side of the equation, and get <em>8(4+s)</em>. To write out the right side of the equation, you would write out <em>12s
</em>to represent 12 small bottles, and <em />subtract <em />24 from that to represent that 8 large bottles is $24 less than 12 small ones.
Then, proceed to solve the equation to get the answer of <em>s=14</em>. Because a small bottle is $14, you can check your work by substituting the 14 in replace of <em>s</em>. <em />
Answer:

f^-1 represents the number of hours the bacteria developed
Step-by-step explanation:

To find inverse of a function , replace f(t) with y

replace t with y and y with x

solve for y
divide both sides by 100

take ln on both sides

divide both sides by ln

multiply by 3 on both sides

Replace x with t and y with f^-1

f^-1 represents the number of hours the bacteria developed
