Answer: average speed of the train = 4,483.0 km/h
Step-by-step explanation:
Speed = Distance / Time
Distance = 66 km
Time = 15.47 cancelling 15, we have 60 sec added to 47 sec
<u> - 14.54</u>
= 14. 107 60 + 47
<u> - 14. 54</u>
<u> 53secs</u>
53secs to hours becomes =
60 secs = 1 min
60 min= i hour
therefore 53seconds =53/3600=0.0147222hours
Speed= 66/ 0.0147222= 4,483.025
Rounding to 1 dp becomes= 4,483.0 km/h
Answer:
Angle A is F Angle A = 57. 52+71=123. 180-123=57
Answer:
C is dependent variable
S is independent variable
Step-by-step explanation:
Here, give the equation, we are told to identify the independent and the dependent variable
When we talk of the independent variable, it is that variable which values does not depend on whatever values the second variable in the equation has. It is that variable that is used to find the other variable in the equation
While the dependent variable depends on the values we input in the equation. It is the variable that we arrive at after plugging different values for the independent variable
now looking at the question, the equation we have is as follows;
c = 0.09s
To get the value of c which is the cost , we have to input different values of a. As is the amount in sales that we have that will yield the value of the commission to be received
Thus, we can categorically say that the values of the commission are dependent on the values we get from the sales
Hence, while commission represents the dependent variable, the values of the sales are the independent variables
Well i guess 8 because 4/5 = 8/10 and 8/10 = .8 so yea
Given: <span>f(x) = log3 (x + 1), look for f^-1 (2)
We are looking for the inverse of a function. The inverse of the function can be obtained by switching the variables and obtaining the values of the new function, before substituting f(2). Using a calculator:
</span><span>f^-1 (2) = 8</span>
