7+(-9)+6+(-10)+(-13)+(-5)=
7-9+6-10-13-5=
-24
mean is the sum of all the numbers divided by the total number of numbers within the data.
-24÷6=-4
The mean is -4.
Answer:
The magnitude of the boat's velocity is 5.66 m/s
Step-by-step explanation:
Given;
Radius of curvature of the circular path, r = 40 m
speed of the boat, v = 0.8 t m/s
The magnitude of the boat's velocity when it has traveled 20 m is ?
a = dv / dt,
v = 0.8 t (differentiate with respect to t)
dv / dt = 0.8 = a
thus, a = 0.8 m/s²
If the boat starts from rest, initial velocity, u = 0
Apply kinematic equation, to solve for the boat velocity at 20 m
v² = u² + 2as
v² = 0 + 2 x 0.8 x 20
v² = 0 + 32
v² = 32
v = √32
v = 5.66 m/s
Therefore, the magnitude of the boat's velocity when it has traveled 20 m is 5.66 m/s
Answer:
b = 35.00
Step-by-step explanation:
To make use of the Law of Sines, you need to know angle B. Of course, its value will make the sum of all angles be 180°, so it is ...
B = 180° -34.5° -29.8° = 115.7°
Then the law of sines tells you ...
b = sin(B)·a/sin(A) = 22·sin(115.7°)/sin(34.5°)
b = 35.00
