Answer:
20 minutes
Step-by-step explanation:
The trains are separating at the rate of 80 +70 = 150 km/hour. The time required to be 50 km apart is then ...
time = distance/speed = (50 km)/(150 km/h) = 1/3 h = 20 minutes
Answer:
(A) The slope of secant line is 18.
(B) The slope of secant line is h+16.
Step-by-step explanation:
(A)
The given function is
At x=3,
At x=9,
The secant line joining (3,27) and (9,135). So, the slope of secant line is
The slope of secant line is 18.
(B)
The given function is
At x=5,
At x=5+h,
The secant line joining (5,55) and 
. So, the slope of secant line is
The slope of secant line is h+16.
If you use the pothaorian theorym (A squared + B squared= C squared) youll be able to figure out the right answer is 65.
Answer: 79
Step-by-step explanation:
Line up the numbers from least to greatest. 39, 42, 44, 51, 55, 62, 66, 72, 77, 81, 94, 86 Then find the Median. Look at the upper part of the data set and from there find the 3rd quartile.
