Answer:
f(t) = 160t,
d = f(t)
The function that relates the distance traveled d to the time t is:
f(t) = 160t, where d = f(t)
Step-by-step explanation:
If the train travels 480 kilometers in 3 hours, then it will travel 160 kilometers in one hour:
d = 160t
Now we replace d by f(t) because d = f(t):
f(t) = 160t
for any given value of t, d will be equal to t multiplied 160 times
No way to tell . . . . . we can't see the chart below.
It must be WAY down there where the sun don't shine.
9 divided by 15 equals 0.6. Did i do that right?
5 hours and 20 minutes because 1/3 as a decimal is 0.3 continued (i wrote down 0.33 so its simplified) and 0.33 decimal hours is 20 minutes.
Answer: 2748.5 feet
Step-by-step explanation:
Given that the
Height h = 120 feet.
angle of depression = 2.5 degrees
The angle of depression is equal to the angle of elevation.
The base of the observation deck will be achieved by using trigonometry ratio.
Tan Ø = opposite/ adjacent
Opposite = height = 120 feet
Adjacent = base = ?
Substitutes the given parameters into the trigonometry ratio.
Tan 2.5 = 120 / adjacent
Adjacent = 120 / tan 2.5
Adjacent = 2748.452
Therefore, the base of the observation deck is 2748.5 feet
