The answer would be 105, it's square root is approximately 10.2469 <span />
Answer:
If 5x-2 = 3x+4, then x=3
Step-by-step explanation:
5x-2=3x+4
Add 2 to both sides, and you get 5x=3x+6. Subtract 3x from both sides, and you get 2x=6. Divide both sides by 2, and what's left is x=3. Hope this helps. :)
Answer:
In this problem, we are given the following functions:
and its inverse function:
First of all, we want to calculate 
. This can be obtained by substituting
x = 2
into f(x). Doing so, we find:
Then we want to calculate 
. We can do it by substituting
x = 1
into 
. Doing so,
Then we want to calculate 
, which can be found by calculating f(2) and then using it as input for 
We know that
f(2) = 1
Therefore,
Then we want to calculate 
, which can be calculated by plugging
x = -2
into . Doing so,
Then we want to calculate 
; by substituting
x = 4
into f(x), we find
Finally, we want to find 
We know already that
So we have:
Answer:
$47.988-$47.99
Step-by-step explanation:
20/100=0.20
39.99x0.20=7.998
39.99+7.998=47.988
Answer:
It depends on the situation being modeled.
Step-by-step explanation:
Assuming the vertex (8.33,236.67) is on a quadratic curve modeling height of an object in feet after t seconds.
Then t=8.33s is the time the object reached the maximum height.
The maximum height is the y-value of the vertex, which is 236.67 feet.
In this case the quadratic curve opens downwards.
The vertex is then the maximum point on this curve.
