Because this graph does not show two arrows pointing away from each other, this becomes an 'and' inequality, which cancels out options A and B. We can also see that the line doesn't go any lower than -2 and doesn't go any higher than 3, so that means x is greater than or equal to -2 and less than or equal to 3. Numerically, this would be -2\leq x\leq 3 or option D.

Solve for x ax+ b= r​
Alexxx [7]

Answer:

x = \dfrac{r - b}{a}

Step-by-step explanation:

ax + b = r

Subtract b from both sides.

ax = r - b

Divide both sides by a.

x = \dfrac{r - b}{a}

The surface area of the triangular prism is of 140 cm².

<h3>What is the surface area of a prism?</h3>

It is the sum of the areas of all faces of a prism. In this problem, the prism has these following faces:

  • One rectangle of dimensions 8 cm and 6 + 4 + 5 = 15 cm.
  • Two right triangles with sides 4 cm and 5 cm.

For a rectangle, the area is given by the multiplication of the dimensions, hence:

Ar = 8 x 15 = 120 cm²

For each right triangle, the area is given by half the multiplication of the sides, hence:

At = 2 x 0.5 x 4 x 5 = 20 cm².

Then the surface area of the prism is:

S = 120 cm² + 20 cm² = 140 cm².

Answer:

54.8 Nm

Step-by-step explanation:

Torque is the cross product of the radius vector and force vector:

τ = r × F

Another way to write it is the product of the radius and force magnitudes times the sine of the angle between the vectors.

τ = rF sin θ

Here, r = 0.366 meters and F = 155 Newtons.  F is in the +y direction, and r is 15° below the +x axis, so the angle between the vectors is 90° − 15° = 75°.

τ = (0.366 m) (155 N) (sin 75°)

τ = 54.8 Nm
