Answer:
- 10 mice left after 5 years
Step-by-step explanation:
<u>The function is given:</u>
- f(x) = 5719(0.28)ˣ
- f(x) is the number of mice left after x years, 5719 is initial number of mice (now) and x is the number of years from now
<u>Substitute x with 5 for 5 years and find the value of the function.</u>
- f(5) = 5719(0.28)⁵ = 10 (rounded up to the integer number)
- Multiply 5719 by 0.28 to the 5th power to get approximate number of 10
There will be 10 mice left after 5 years
I think it’s D because they are never going to touch
Your answer would be 45 and 1/3
You can convert between the various different sizes by merely moving the decimal point the correct number of places. The basic metric units are meters (for length), grams (for mass or weight), and liters (for volume).
Answer:
f^-1(x) is 6x + 48
f(x) = 1/6x - 8
To find f^-1(x) equate f(x) to y
That's
f(x) = y
y = 1/6x - 8
Next interchange the terms
We have
x = 1/6y - 8
Make y the subject
Multiply through by 6
We have
6x = y - 48
y = 6x + 48
Therefore f^-1(x) is 6x + 48
Hope this helps you
