Answer:
1.958 * 10^-5 seconds or 0.00001958 seconds.
Step-by-step explanation:
3740 = 3.74 * 10^3 in scientific notation.
Time = distance / speed.
= 3. 74 * 10^3 / 1.91 * 10^8
= 1.958 * 10^-5 seconds.

Answer:
AC=18.1cm
Step-by-step explanation:
When we subtract 11-4=7cm we get one cathetus of the right triangle a=7cm also we know hypotenuse which is c=16cm.
We will use Pythagorean theorem to find the second cathetus b
b=√16∧2-7∧2= √256-49= √207 ≈ 14.39cm =DC =>
AC =√(DC)∧2+(AD)∧2= √14.39∧2+11∧2= √207+121= √328= 18.1cm
AC=18.1cm
