Answer:
70
Step-by-step explanation:
Answer:
x=4 or x= - 16
Step-by-step explanation:
|x+6|
Now subtract 7 which equals to 3.
|x+6|-7=3
|x+6|=10
Now remove the mode by adding plus minus sign in the front of 10.
x+6=±10
x+6=10 or x+6=-10
x=4 or x=-16
Answer:
i. a = 8.7, b = 7.1 and c = 11.2
ii. A = , B = and C =
Step-by-step explanation:
Given a right triangle with, b = 7.1 and B = .
I. Applying the trigonometric function to determine leg a, we have;
Tan θ =
Tan =
a =
= 8.675
The length of leg a is 8.7.
ii. To determine leg c,
Sin =
=
⇒c =
= 11.21
The length of leg c is 11.2.
iii. Given that: B = and C =
Then,
A + B + C = (sum of angles at a point)
A + + =
A + =
A = -
=
Draw a diagram (shown below) to illustrate the problem.
The rotational speed is
ω = (3 rev/min)*(1 min/60 s)*(2π rad/rev) = π/10 rad/s
The period is
T = 2π/ω = 20 s
The amplitude of the rotational motion is equal to the radius of 15 ft.
At t=0, the height of the tip of the blade is horizontal to the right, therefore its motion relative to the ground is given by
A plot of the motion is shown below.
