Answer:

Step-by-step explanation:
There is a formula that can be used to find the x-value of the vertex of the parabola. This formula is 
We have the function 
From this function, we can find that

We can plug in our know values into the formula to get

Then we can plug in our x-value to find the y-value of the vertex

This means that the vertex would be 
Answer:
25.047 or roughly 25.
Step-by-step explanation:
I solved it wrong the first time then i double check with wolframalpha and got the correct number.
We know that the area of the tile is 18
and it makes a triangle, we also know the base and height. In this case the base is 2
and the height is also given which is
.
Area of triangle =
,
substituting we will end up with 18
=( 2
*
) / 2
Here is the tricky part
, i totally forgot about that lol.
Simplifying: we will get 18
= 
Now, in order to find the x, we will need to take the log of both sides.

Solving for x we end up getting:
= x
where x = 25.047.
To be honest I deserve a nobel prize not a brainliest lol.
Good question bro, take it easy.
The formula is d=C/π.
The diameter is 2 times the radius
The formula for the circumference using the radius is 2πr.
in order to do this backwards, we would have to do 16÷2÷π, but we're not looking for the radius.
Therefore, we take out the ÷2 part, which would be 16÷π
16 is the circumference
16÷π=d
d=C÷π
=7x^4+15x^3+4y^2 I hope this helps!!
Answer:
-3
Step-by-step explanation:
h(k(2)) = h(k(x=2)) = h(-2) = h(x= -2)= 3/( -2+1) = 3/-1= -3
sorry if I'm wrong.
