1) To find a square root means to find the number that multiplied by itself gives you the given number. Since both a positive number multiplied by itself and a negative number multiplied by itself give you a positive number, we can say that every positive number has two square roots, one positive and one negative.
In order to find the square root of 0.0064, you need to think the number without the comma, in your case then 64. The square root of 64 is 8 (indeed 8x8=64).
You know need to decide how many decimals your root needs to have: since the given number had 4 decimals, you have to halve, therefore your root will have 2 decimal: 0.08
The square roots you are looking for are +0.08 and -0.08
2) To find the real-number root means to find the number that gives you real roots if square rooted. Since negative numbers give you imaginary numbers if square rooted, your answer has to be 1.1, the only positive number.
Answer:
7.9 miles
Step-by-step explanation:
pi = 3.14
r = radius = 10 miles
c = circumference
substituting the values
c = 2pi*r
c = 2 * 3.14 * 10
c = 62.83 miles
The ship has traveled 45° due north
so,
d = ( total circular distance * 45 ) / 360
substituting the values:
we get;
d = ( 62.83 * 45 ) / 360
= 7.85 miles
= 7.9 miles
Answer:
Step-by-step explanation:
Total height lowered = 75m
No of times balloon lowered = 5
Height lowered in each lowering = Total height lowered / No of times balloon lowered
= 75 / 5
= 15 m
The number indicated that each time balloon is lowered by 15 m
