The vertex form of all expressions is given below.
We have given that the expressions
We have to write the function in vertex form.
<h3>What is the vertex form of the equation?</h3>
The vertex form of a quadratic function is given by f (x) = a(x - h)^2 + k, where (h, k) is the vertex of the parabola.
Therefore the first equation
it can be written as
The second equation can be written as
vertex for is,
The third equation is,
Vertex form is,
Forth equation is,
Vertex form is,

We're looking for C(h), where h is the hundreds of shirts. The fact that they cost "$500 for each additional 100 t-shirt" tells us the slope is 500. Knowing that 1 hundred costs 750, we could use point-slope at this point: (C - 750)/(h - 1) = 500C - 750 = 500h - 500C(h) = 500h + 250 We can check that C(1) = 750 and C(2) = 1250, as we expect. I'll leave it to you to evaluate C(5).
Answer: 33 degrees
Step-by-step explanation:
Angles inscribed in the same arc are congruent, so
Answer:
Step-by-step explanation:
Starting from the right, put this into groups of three so you can see for sure where a million is.
254 212 610
A million is right where the 4 is. So use the hundred thousands (the second 2) to round to the nearest million. Since 2 is less than 5, it rounds like this.
254 000 000
Answer:
See explanation
Step-by-step explanation:
To solve the equation 
graphically, we need to consider left and right parts of this equation separately.
Left side gives us the function 
The graph of this function is shown with green curve in attached diagram.
Right side gives us the function 
The graph of this function is shown with blue curve in attached diagram.
The x-coordinates of the points of their intersections are the solutions to the equation
From the graph you can see that the solutions are
