Hey, this question concerns the inscribed angle theorem.

The formula for this is:

∠ABC = 2*∠ADC

∴ ∠ABC = 40°

For proof, look up 'inscribed angle theorem (or central angle theorem)' on YT.

the axis of symmetry for a function in the form f(x)=x^2+4x-5 is x=-2. what are the coordinates of the vertex of the graph?

Alenkasestr [34]

Hello :
f(x)=x²+4x-5
The axis of symmetry for a function in the form f(x)=x^2+4x-5 is x=-2 :
f(x) = (x+2)² + b
f(x) x²+4x+4+b= x² +4x-5
4+b= -5
b = -9
the vertex is : (2 , -9)

At Mario's Pizza, a large pizza has a diameter of 18 inches. What is the area of two pizzas?

irinina [24]

First, the area of the pizza then double it.

Area for a circle: Area = $\pi$ * r^2

Plug in the values.

We will use 3.14 for $\pi$ .

We need the radius. So half the diameter to get the radius.

18 / 2 = 9

Area = 3.14 * 9^2
Area = 3.14 * 81
Area = 254.34

Then multiply 2 to get the double the area.

254.34 * 2 = 508.68

So, the answer to this question is D. 508.68 in. 2.
