Answer:
10.9
Step-by-step explanation:
Pythagoras theorem- a² + b² = c²
Since this is a right angle with each side on the right angle's length given you can use pythagoras theorem.
7² + 8.44² = c²
= 49 + 70.56 = c²
= 119.56 = c²
∴ c = √119.56
= 10.9
2(4a^2 +a +3)
Factor out the 2
So in 1 hour, the parachutist will fall 12 miles or
12 mi/1hour
convert
1 hour=60 mins
1 min=60 seconds
1 hour=60 times 60 seconds=360 seconds
12 miles per 360 seconds
convert miles to feet
5280 feet per mile
12 miles times 5280=63360 feet
63360/360
do the math and simplify
63360/360=6336/36=176
176 feet per second
