B
You would divide 45 mm/15mm to get 3. Multiply 3 by 27 to get 81 mm.
Answer:
2758 Nm
Step-by-step explanation
Work done usually depends on two things force applied and distance travelled due to applied force. In this current scenario, the force is being applied at an angle so we will have to find a component of force in the direction of the movement.
We usually find component using cos θ.
Here θ is 40°
Now, the modified equation becomes,
Work Done = Force * Distance * Component of force along the direction of distance
∴ Work = 30 N * 120 m * Cos 40°
⇒Work = 30 * 120 * 0.766
⇒Work = 2757.6 Nm
Rounding to the nearest whole number.
∴ The work done by force is 2758 Nm which is option B
Answer:
a, b, f, and h
Step-by-step explanation:
Answer:
-8 = m-2+b
-2 = m-0+b
4 = m2+b
10 = m4+b
Step-by-step explanation:
You just put them in y = mx+b format
The formula for the value of nth term is
= 3n + 1
Step-by-step explanation:
The formula of the nth term in the arithmetic sequence is
, where
- a is the first term of the sequence
- d is the common difference between each two consecutive terms
∵ The first term of an arithmetic sequence is equal to four
∴ a = 4
∵ The common difference is equal to three
∴ d = 3
- Substitute these values in the rule of the nth term
∵ 
∴ 
- Simplify it
∴ 
∴ 
The formula for the value of nth term is
= 3n + 1
