Answer:
about 2.81 km/h
Step-by-step explanation:
It can be useful to draw a diagram.
The lines pointing to due north from points B and P are parallel, so the angle BCP and the bearing of point C from P are the same, 30°. The angle BPC will be the difference of bearings of B and C at P, so is 47-30=17°. This is enough information to solve the triangle using the Law of Sines:
PB/sin(C) = CB/sin(P)
CB = PB·sin(P)/sin(C) = (1200 m)·sin(17°)/sin(30°) ≈ 701.7 m
The speed of the boat is then ...
x = distance/time = (0.7017 km)/(1/4 h) = 2.8068 km/h
Answer:
Step-by-step explanation:
The slope formula is M=y2-y1
______
X2-X1
Ex. (-1,1) and (1,-2)
x1,y1 x2,y2
-2+1 -3
_____= ____
1+(+1) 2
Graph:
Any linear function can be quickly graphed using the form: y=mx+b
X: independent variable
y: dependent variable
M: slope
b: y-intercept
(When you don't have a denominator for M put a 1 Ex. 4--> 4/1)
Ex. y=-1/2x + 4
M= 1/2
B: 4
Rise/Run = -1/2 "rise" (being the change in y, going up or down) divided by the "run" (being the change in x, going from left to the right).
Answer: A 17.5 square units
Step-by-step explanation:
The area of a triangle is Half of the base times the height.
A = 35/2
A = 17.5
Answer:
36.7
Step-by-step explanation:
32+16+54+60+26+32=220
220 divided by 6 is 36.6666666666
