Hey can you please help
AfilCa [17]

Answer:

Measure of major arc BDC = 260.5°       Option A

Step-by-step explanation:

Given that, measure of central angle ∠BAE = 80.5°

Firstly we will find the measure of arc BE .  

The measure of arc BE  is same as the measure of its central angle.

So, measure of minor BE arc = 80.5°

measure of arc EDC = 180°  because of half circle

So,

measure of major arc BDC = 180° + 80.5° = 260.5°       option A

That's the final answer.

Bess [88]

Answer:

Anything 3 or more

Step-by-step explanation:

3 x 4 = 12.

12 > 10.

If you follow through with the next multiple of 4, 4, we get 16.

16 > 10.

This is true for any other multiple of 4, making any value 3 or me greater than 10.

What do exponential functions model in the real world? How does the
sineoko [7]

They model various situations where there is an increasing curve. An example is if you throw a baseball and it curves back down as gravity has more and more of a affect on it. This would be a different equation than if you threw a basketball as the basketball wouldn't go as high but would have about the same downwards acceleration due to gravity.
