Answer:
32.33 <= m
Step-by-step explanation:
Since we are dealing with below sea level our initial starting point and max level will both be negative values, while our descending rate will also be negative because we are going down. Using the values provided we can create the following inequality...
-400 <= -12m - 12
Now we can solve the inequality to find the max number of minutes that the submarine can descend.
-400 <= -12m - 12 ... add 12 on both sides
-388 <= -12m ... divide both sides by -12
32.33 <= m
Answer:
1.28 m
Step-by-step explanation:
The speed at which water rises in the tank is proportional to the speed of the water in the pipe and inversely proportional to the ratio of the tank area to the pipe area.
The ratio of tank area to pipe area is the square of the ratio of their diameters:
((150 cm)/(4 cm))² = 1406.25
Then the rate of rise of water in the tank is ...
(0.5 m/s)/(1406.25)
After 1 hour = 3600 seconds, the height of the water will be ...
rise = (time)(rate of rise)
(3600 s)(0.5 m/s)/1406.25 = 1.28 m
Your equations would be:
X * y = -5
X + y = 2
Your answer would be -1.5 and 3.5

we know that
<u>The correlation coefficient</u> is a measure of linear association between two variables. Values of the correlation coefficient are always between −1 and +1.
Using a mathematical tool-------> Excel software
Find the correlation coefficient
see the attached table N 1 and N 2
the answer is
Part 1) The correlation coefficient of the data is 0.02
Part 2) The correlation coefficient of the data is 0.98
Answer:
Rate=9.05%
Step-by-step explanation:
Let P represent the Principal ,t the time = 8 years and r be the rate of interest.
It is given money doubles in 8 years so A=2P.
The compound interest is given by the formula :
Substituting the values we have:
Dividing both sides by P :
1.0905-1=r
r=0.09050
r=9.05%
