He uses sin(x):
sinx = opposite side/hypotenuse = y/ (distance eath-sun)
Since x is known and y is known, then:
Distance earth-sun = y/sinx
So the the answer would be calculated in this way: 10*11/100 + 6*7/100 = 110/100 + 42/100 = 1.1 + 0.42 = 1.52
Answer: 1.52 gallons
Let the distance of diver from boat = d
depth = h = 248ft
sin 26 = h/d
⇒ 0.438 = 248/d
⇒ d = 248/0.438
⇒ d = 566.21 ft
distance is 566.21 ft
Answer:
1980
If you divide 99 and 0.05 you'll get 1980.
Sorry if I'm wrong!
y - y1 = m(x - x1) Point slope form
y - y1 = 4(x - x1) Plug in the given slope m = 4
y - (-10) = 4(x - 3) Plug in the given (x1,y1) point
y + 10 = 4(x - 3) Simplify
y + 10 = 4x - 12 Distribute
y+10-10 = 4x - 12 - 10 Subtract 10 from both sides
y = 4x - 22 Combine like terms
Answer is choice A
