231 chairs because 9 times 25 is 225, plus 6 is 231
Answer:
a) 122.5 m ; b) 10 s
Step-by-step explanation:
Just use the given equation and plug in what you know.
a)
d = 4.9t^2
d = 4.9(5^2)
d = 4.9 * 25
d = 122.5 m
b)
d = 4.9t^2
490 = 4.9t^2
100 = t^2
t = 10 s
Answer:
The inverse of this function is f(x) = 3x - 6.
You can find the inverse of any function by switching the f(x) and x values. Once you've done that, solve for the new f(x). The result will be the inverse function. The step-by-step process is below.
f(x) = 1/3x + 2 ---> Switch f(x) and x values
x = 1/3f(x) + 2 ---> Subtract 2 from both sides
x - 2 = 1/3f(x) ----> Multiply both sides by 3
3(x - 2) = f(x) ----> Distribute the 3
3x - 6 = f(x) ----> Place in the proper order for formatting purposes
f(x) = 3x - 6
And that is your inverse function.
