Answer:
Each length of the rope will be 0.8 feet long
Answer:
1107 feets below sea level
Step-by-step explanation:
Given that :
Initial elevation of submarine = 984.6 feets below sea level
Depth of dive from initial elevation = 122.4 feets below sea level
The elevation after the dive :
Initial elevation + depth of dive
984.6 + 122.4
= 1107 feets below sea level
Answer:
It should be $50.00.
Step-by-step explanation:
It shows that every 2 mins. adds 20 cents to the bill. I wrote out the numbers and did this:
6 30.60
8 30.80
10 40.00
12 40.20
14 40.40
16 40.60
18 40.80
20 50.00
Step-by-step explanation:
there is no real number solution for the square root of a negative number.
a sqare root multiplied by itself had to deliver exactly the number inside the square root.
so for sqrt(-49), what can be the answer ?
which number multiplied by itself gives -49 ?
it any negative number at that.
because
a × a = a²
and
-a × -a = a² but definitely not -a².
we get a negative number only, when we multiply a positive number with a negative number or vice versa.
the only solution is complex or imaginary (based on the imaginary number i):
i² = -1
i = sqrt(-1)
so, sqrt(-49) = sqrt(49 × -1) = 7×sqrt(-1) = 7i
but again, no real solution.
