Answer:
(3, 6)
Step-by-step explanation:
You add the x points together and divide by two, then you add the y points together and divide by 2.
To solve the question we shall use the formula for the range given by:
Horizontal range, R=[v²sin 2θ]/g
plugging in our values we get:
500=[160²×sin 2θ]/10
5000=160²×sin 2θ
0.1953=sin 2θ
thus:
arcsin 0.1953=2θ
11.263=2θ
hence:
θ=5.6315°~5.63
Step-by-step explanation:
0.08*300 + 0.13x = 51.95
Multiply thru by 100 to get:
8*300 + 13x = 5195
13x = 5195-2400
13x = 2,795
x = 215 hours
