Basically the inverse is when you reflect the function across the identity line, y=x
basically to find the inverse of a function
flip switch all x and y and solve for y, then replace y with finverse
f(x)=7x-13
y=7x-13
switch
x=7y-13
solve for y
x+13=7y
(x+13)/7=y
finverse=(x+13)/7
3rd one
quantity of x plus 13 over 7
For most questions asking for the area of a part of a figure, you first have to find the area of the figure then divide to get the part. Because the water level is 2/3 up, we can divide by 3 and that would make it the needed 1/3.
Volume of a rectangular prism: L*W*H
3 3/4 * 3 3/8 * 13 1/3
Becomes
168 3/4
Then divide by 3
56 1/4
or
56.25
What is another way to write the equation <span>?
</span>
Step-by-step explanation:
f(x) = |x-7| + 3
when x is equal to 4, then
f(4) = |4-7| + 3
=-3+3
=0
<h2>
Hello!</h2>
The answer is:
The ball will hit the ground after
<h2>
Why?</h2>
Since we are given a quadratic function, we can calculate the roots (zeroes) using the quadratic formula. We must take into consideration that we are talking about time, it means that we should only consider positive values.
So,
We are given the function:
Where,
Then, substituting it into the quadratic equation, we have:
Since negative time does not exists, the ball will hit the ground after:
Have a nice day!
