Answer:
Step-by-step explanation:
eq of circle is (x-h)²+(y-k)²=r²
where (h,k) is center of circle and r is the radius.
given eq. of circle is (x+10)²+(y-4)²=100
or {x-(-10)}²+(y-4)²=10²
center is (-10,4)
and radius =10 units
Answer:
0.0000302
Step-by-step explanation:
When 10 is to the power of a negative number, "move" the decimal dot left.
10⁻⁵ means to "move" the decimal 5 times to the left.
1. Write a bunch of extra 0's for the coefficient. (The coefficient is 3.02).
0000003 . 02
2. Count 5 place values over.
00←0←0←0←0←3 . 02
3. Put the decimal behind the digit.
00 . 0000302
4. Get rid of the 0s that you don't need. You only need one 0 left of the decimal.
0.0000302 <= Final answer
One billionth of a second
