Answer:
33.16ft
Step-by-step explanation:
Sin 56° = x / 40ft
0.829 = x / 40ft
x = 40ft * 0.829
x = 33.16ft
Domain is everything below 0. Range is all real numbers. It is a function as it passes the vertical line test.
The Tama monorail runs for 18 hours every day.
Answer:
23.6 ft
Step-by-step explanation:
Sketch a right triangle representing this situation. The length of the hypotenuse is 26 ft and the angle of elevation from ground to top of ladder is 65°. The "opposite side" is the reach of the ladder, which we'll call x.
Then:
opp
- sin 65° = ----------
- 26 ft
or (26 ft)(sin 65°) = opp side = height off the ground of top of ladder.
Evaluating this, we get:
(26 ft)(0.906) = 23.56 ft, or, rounded off, 23.6 ft
The ladder reaches 23.6 ft up the side of the building.
386 divided by 20 is 19.3 so Greg averaged 19.3 miles per gallon.
