Answer:
Step-by-step explanation:
It is given that,
The sun produces of radiant energy per second.
We need to find how many ergs of radiant energy does the sun produce in .
Energy produced in 1 seconds =
In , energy produced is :
Hence, the radiant energy produced in 1 second is .
1,-4/5
there two zeroes
f(x) =x2- 10x +21
10x-2x=21
8x = 21
x =21/8
x = 2.625
