lara31 [8.8K]

Answer:

5m/s²

Step-by-step explanation:

<u>Given </u><u>:</u><u>-</u><u> </u>

  • Initial Velocity = 40m/s
  • Final velocity = 60 m/s
  • Time = 4s

<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u><u> </u>

  • The acceleration .

<u>Solution</u><u> </u><u>:</u><u>-</u><u> </u>

We know that the rate of change of velocity is called acceleration. Therefore ,

\sf\implies a = v - u / t \\

\sf\implies a = 60m/s - 40m/s/ 4 \\

\sf\implies a = 20m/s \div 4 \\

\bf\implies a = 5m/s^2

Help please I dont understand this​
s2008m [1.1K]

Answer:

x=6

Step-by-step explanation:

The lengths of line segments \overline{AB} and \overline{AC} because of the two segments and two angles marked as equal in the diagram. Because of this, the arcs \widehat{AB} and \widehat{AC} are equal.

Since there are 360 degrees in a circle, we can now set up the following equation:

(10x-23)+(10x-23)+106=180,\\20x-46+106=180,\\20x+60=180,\\20x=120,\\x=\boxed{6}
