(-3, -2) is the vertex. 

You can find this by plugging into -b/2a to find the x value and using the x value to find the y value. 

And another spot on the vertex would be (0, 16), which is the y intercept.

A piece of property valued at $56 100 is assessed for property tax purposes at 11 of its value. If the property tax rate is $3.7
Ksivusya [100]

Answer:

Properties are assessed for tax pruporses taking a fraction of property value and applying the tax rate.

In this case say at 11 of its value (I suposse that it means 1/11)

So the value assesed is

56100*\frac{1}{11}=5100

Applying the tax

5100*\frac{3.75}{100}=191.25

So the amount levied is $191.25 in the case that the property is assessed at 1/11 of its value. In other case you can follow the same procedure using the respective fraction.

Chicago Pizza charges $10.49 for a medium 14" pepperoni pizza and NY Pizza charges $20.99 for an x-large 18" pepperoni pizza.
Leona [35]

Answer;

The cost is $0.07 per  square inch

Step-by-step explanation:

In this question, we are asked to calculate the cost of the Chicago pizza per square inch rounded to the nearest cent.

Firstly, we will need to calculate the area occupied by the 14 inch medium pepperoni pizza made by Chicago pizza

Since the pizza is circular in shape, we use the formula for the area of a circle to calculate its area in square inch

Mathematically, the area of a circle is equal to π . Here, our r is half the size of the pizza as the 14 inch represents the full length of the pizza across the center of the pizza ( This is the diameter) d=2r or r = D/2 = 14/2=  7 inch

The area is thus = 22/7 × 7 × 7 = 154 square inch

Now, since the full pizza costs $10.49, the cost of the pizza per square inch is 10.49/154 = 0.068 = $0.07 per  square inch
