a. The equation that describes the forces which act in the x-direction:
<span> Fx = 200 * cos 30 </span>
<span>
b. The equation which describes the forces which act in the y-direction: </span>
<span> Fy = 200 * sin 30 </span>
<span>c. The x and y components of the force of tension: </span>
<span> Tx = Fx = 200 * cos 30 </span>
<span> Ty = Fy = 200 * sin 30 </span>
d.<span>Since desk does not budge, </span><span>frictional force = Fx
= 200 * cos 30 </span>
<span> Normal force </span><span>= 50 * g - Fy
= 50 g - 200 * sin 30

a. The equation that describes the forces which act in the x-direction:
(200N)cos(30) - F_s = 0
b. The equation that describes the forces which act in the y-direction:
F_N - (200N)sin(30) - mg = 0
c. The values of friction and normal forces will be:
Friction force= (200N)cos(30),
The Normal force is not 490N in either case...
Case 1 (pulling up)
F_N = mg - (200N)sin(30) = 50g - 100N = 390N
Case 2 (pushing down)
F_N = mg + (200N)sin(30) = 50g + 100N = 590N
Answer:
correct answer is option C.
Step-by-step explanation:
net income of a year = $35,000
accounts receivable is increased (AR)= $7,000
accounts payable decrease(AP) = $3,000
depreciation expense = $8,000
net cash provided = net income - increase in current asset (AR) - decrease in current asset (AP) +non cash flow
net cash provided = $35,000 -$7,000-$3,000+ $8,000
= $33000
hence the correct answer is option C.
Answer:
x = 4 ± 
Step-by-step explanation:
Given
x² - 8x = 3
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 4)x + 16 = 3 + 16
(x - 4)² = 19 ( take the square root of both sides )
x - 4 = ± ( add 4 to both sides )
x = 4 ±
Answer:
2 sales
Step-by-step explanation:
Based on the plot of discrete probability, it can be seen that the distribution is symmetrical and the peak occurs at the stock of 30. If there is a sale of less than 30 such as 20 or 25, the seller is at a loss. Similarly, if the demand is above 30 such as 35 or 40, the seller is also at a loss. Therefore, there is approximately 2 sales to be lost each day based on the decision made by the seller.
