Answer:
The bearing is N 55.62° W
Step-by-step explanation:
ship leaves the port of Miami with a bearing of S80°E and a speed of 15 knots.
It then turns 90° towards the south after one hour.
Still maintain the same speed and direction for two hours.
The bearing is just the angle difference from the ship current location to where it started.
Let the speed be km/h
Distance covered in the first round
= 15*1
= 15km
Distance covered in the second round
=15*2
= 30 km
Angle at C = (90-80)+90
Angle at C = 10+90= 100
Let the distance between the port and the ship be c
C²= a² + b² -2abcos
C²= 15²+30²-2(15)(30)cos 100
C²= 225+900+156.28
C²= 1281.28
C= 35.8 km
Using sine formula
30/sin x= 35.8/sin 100
30/35.8 * sin 100 = sinx
0.838*0.9848= sin x
0.8253= sin x
Sin ^-1 0.8253 = x
55.62° = x
The bearing is N 55.62° W
The answer is three, 150 square feet
The answer is y = 14
Explanation:
AC≅CB, so the triangle is isosceles
So, m∠A = m∠B
m∠A = 50 and m∠A = m∠B, so m∠B = 2x = 50
The sum of all angles in a triangle is 180°
So:
180 = (5y + 10) + 50 + 50
180 = 5y + 10 + 100
180 = 5y + 110
-5y = 110 - 180
-5y = -70
5y = 70
y = 70/5
y = 14
Hope it helps!
Answer:
114
Step-by-step explanation:
if,
24inches=72cents
38inches=?
we cross multiplication,
38times72=2736 divide with 24=114
The answer is114
I would say age of a plant to its height is a function while the others are not.
