smaller r = -10

larger r = 6

The ordered pair for the vertex of the parabola is

Step-by-step explanation:

We have the function

In order to factor this quadratic equation, we need to look for two numbers that will

Add together to get 4

Multiply together to get -60

Lets look for the numbers that multiply to give us -60.

-1 and 60

1 and -60

2 and -30

-2 and 30

3 and -20

-3 and 20

4 and -15

-4 and 15

5 and -12

-5 and 12

6 and -10

-6 and 10

Now, we just need to determine which of these numbers will add together to get us 4.

Those two numbers would be -6 and 10.

This means that our factored form of this equation will be

From this, we can find our roots, which are the solutions to the equation when it is equal to 0.

These are our r values.

The vertex of a parabola will always be directly between the two roots.

The number that is between -10 and 6 is

To find the y-value of the coordinate pair, we just need to plug -2 into our function.

This means that the ordered pair for the vertex of the parabola is

answer is 12345678900987654321234567890987654321

step-by-step explanation:

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees
