Answer:

t = 0, t = - 2

Step-by-step explanation:

Given

- t² - 2t = 0 ← factor out t from each term

t(- t - 2) = 0 ← in standard form

Equate each factor to zero and solve for t

t = 0

- t - 2 = 0 ( add 2 to both sides )

- t = 2 ( multiply both sides by - 1 )

t = - 2, thus

solutions are t= 0, t = - 2

Answer:

1) x= -2

2) x= 3

3) x=7

4) x>5

5) x=-14

Step-by-step explanation:

1) −3x − 3 −7x = 17

−10x−3=17

−10x=17+3

−10x=20

x= -20/10

x=-2

2) 10x − 6 = 24

10x=24+6

10x=30

x= 30/10

x= 3

3) −4−5x=−39

−5x=−39+4

−5x=−35

x=-35/-5

x= 7

4) 3x - 5 > 10

3x>10+5

3x>15

x>​15/3

x>5

5)  -5 + x + 16 = -3

x+11=−3

x=−3−11

x=-14

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
