1.7 hrs
Step-by-step explanation:
We can use cosine law to find the distance d:
where. a = 3 mi
b = 4 mi
gamma = 71.7°
d^2 = (3mi)^2 + (4 mi)^2 - 2(3 mi)(4 mi)cos(71.7)
= 9 mi^2 + 16 mi^2 -24cos(71.7)
= 17.464 mi^2
or
d = 4.2 mi
To find the time it takes for him to go from the cave to the waterfall, divide this distance d by his walking rate of 2.5 mi/hr:
t = d/v = 4.2 mi/2.5 mph
= 1.7 hrs
Answer:
answer is D. geometric
Step-by-step explanation:
7*2=14*2=28*2=56*2=112
False. consider u1 = (0, 0, 0), u2 = (1, 0, 0), u3 = (0, 1, 0), and u4 = (0, 0, 1).

You give us the answer right now. It's the answer to :
<span>If {u1, u2, u3} does not span R3, then neither does {u1, u2, u3, u4}.

Answer:
42c
Step-by-step explanation:
To find the answer, times 80 by 3 (240 miles). Then, 34 times 7 = 238, which means you would end up with a mixed number (238 2/34.) Hope this helps :)
