It it 270 degrees for the shaded part of it
Shifting a graph up by c units involves adding c to the whole function
therefor
y=ax^2+c is c units higher than y=ax^2 (aka, it is shifted c units up)
If you are making 4 billion a second do 4,000,000,000 x 60 = 240,000,000,000
Then times that by 10 which equals. 2,400,000,000,000
Is the answer for the second one
6,000,000,000 x 60 x 60 x 2 = 1,296,000,000,000,000
The relation between arc length and exterior angle is given in the figure.
Now we are given far arc length as DE =124
We are given near arc length as BC = 36
So plugging in the formula to find measure of angle A:



Angle A = 44 degrees
Answer : A) 44 degree
