Answer:
(-3, 2)
Step-by-step explanation:
Be just a bit clearer, please: "find the vertex."
You could either "complete the square" or use the "quadratic formula."
Here the coefficients are a=-1, b=11 and c=-18. Because a is -, the curve opens downward and the vertex is on top, representing the function's maximum.
Use the quadratic formula with the coefficients given above.
-b plus or minus sqrt(b^2-4ac)
x = -------------------------------------------
2a
Step 1
calculate the value for i=1
=(4*(1/2)<span> ^(1-1))---> 4
step 2
</span>calculate the value for i=2
=(4*(1/2) ^(2-1))---> 2
step 3
calculate the value for i=
=(4*(1/2) ^(3-1))---> 4*(1/4)---->1
step 4
find the sum
(4+2+1)=7

Answer:
Step-by-step explanation:
Let's first get our variables straight. M is how much money you make each night, and h is the amount of hours she works.
This means that M will be what our function is equal to, aka the y-axis. h will be the x-axis.
We know that you earn a rate of $50 per night through tax, and your hours worked doesn't influence this in any way. That means there will be a constant on this function, +50.
We also know that you earn 7.50$ per hour, which is directly influenced by how many hours you work, so we will have .
Combining this all together, we get
.
Hope this helped!
