Answer:
The rate of travel is 105.6 feet per second, so 211.2 feet could be travelled in 2 seconds.
Step-by-step explanation:
If you take 5280 times 72 it equals 380160 which is the total amount of feet travelled in an hour so you divide it by 60 giving you 6336 which is the total feet travelled in 1 minute and you divide it 1 more time to get 105.6 which is the total feet travelled in 1 second. Hope this helps!
We have a triangle, when:
hypotenuse=slant height=20 ft
opposite side=height of the tree=?
angle formed by the tree with the ground=72º
sin Ф=opposite/ hypotenuse ⇒ opposite=(hypotenuse)(sin Ф)
In this case:
oppssite=20 ft /sin 72º=19.021...≈19
Answer: the heigth of the tree is 19 ft.
Answer: the answer is C because it is the only one that matches with one pair on the table wich is (4,2)
