The force needed to keep the cart at rest is 149.022 pounds

<h3>Force and Motion</h3>

Given Data

  • Weight of cart = 200 pounds
  • Angle = 40 degree

The force needed to keep the cart at rest is the vertical component of the resultant force, hence we have

Fy = Mg sin θ

Substituting our given data we have

Fy = 200 sin 40

Fy = 200 *0.74511

Fy = 149.022 pounds

Find the measure of angle Y. Round your answer to the nearest hundredth. (Please type the numerical answer only)
Sati [7]

Answer:

y = 11.54°

Step-by-step explanation:

Reference angle = y°

Opposite side length = 4

Hypotenuse = 20

Apply trigonometric function SOH:

Sin(y) = \frac{Opp}{Hyp}

Sin(y) = \frac{4}{20}

Sin(y) = 0.2

y = Sin^{-1}(0.2)

y = 11.536959° ≈ 11.54° (nearest hundredth)

Perform the addition.<br> (3x² + 3x - 5) + (-7x² + 9)
lakkis [162]
The question is asking us to find the sum. To do this, let's first write the original equation and then take it from there.
(3 x^{2}  + 3x - 5) + (-7 x^{2}  + 9)<span>
Use distributive property:
</span>3 x^{2}  + 3x - 5 - 7 x^{2}  + 9
Combine Like Terms:
&#10;-4 x^{2} +3x+4
Therefore, the answer to your question is -4x² + 3x + 4. Hope this helps and have a fantastic day!
