If 8-2x<12 is -2 a solution to the inequality

Mathematics

Answer: No

Step-by-step explanation: To determine whether <em>x = -2</em> is a solution to the inequality, substitute a <em>-2</em> in for <em>r</em>.

So we have 8 - 2(-2) < 12.

Notice that I used parentheses.

This is a great habit to get into when

substituting numbers in for variables.

So we have 8 - (-4) which can be changed to 8 + (+4) or +12.

Since 12 is not less than 12, -2 is not a solution.

Answer:

no

Step-by-step explanation:

Let's plug in -2 for x.

8 - 2 (-2) <12

8 + 4 < 12

12 < 12

Since this is a false statement, -2 is not a solution to the inequality.

dsp73

Answer:

The magnitude of the boat's velocity is 5.66 m/s

Step-by-step explanation:

Given;

Radius of curvature of the circular path, r = 40 m

speed of the boat, v = 0.8 t m/s

The magnitude of the boat's velocity when it has traveled 20 m is ?

a = dv / dt,

v = 0.8 t (differentiate with respect to t)

dv / dt = 0.8 = a

thus, a = 0.8 m/s²

If the boat starts from rest, initial velocity, u = 0

Apply kinematic equation, to solve for the boat velocity at 20 m

v² = u² + 2as

v² = 0 + 2 x 0.8 x 20

v² = 0 + 32

v² = 32

v = √32

v = 5.66 m/s

Therefore, the magnitude of the boat's velocity when it has traveled 20 m is 5.66 m/s
