Answer:
a. 7.64 km/h
b. 6.0°
c. see below
Step-by-step explanation:
a) The total velocity of the boat is ...
7i +(0.6i +0.8j) = 7.6i +0.8j
The magnitude of this velocity is the speed of the boat, relative to land. That is given by the Pythagorean theorem.
|7.6i +0.8j| = √(7.6² +0.8²) = √58.4 ≈ 7.642 . . . . km/h
__
b) The angle of the total velocity with respect to the "i" direction (the direction of vector v) is ...
α = arctan(0.8/7.6) ≈ 6.009°
__
c) The boat is headed in a direction 6° different from its velocity relative to the water. That may need to be accounted for if the boat is traveling any significant distance.
Answer:
8.46/6 = 1.41
Step-by-step explanation:
X=24
To find the value of x, you have to divide 48 by 2.
The slope of the line is (1/2).
The original equation is y=mx+b
m = slope
x = variable
b = y-intercept
The answer would be 34.8 I’m pretty sure
