A number that is a multiple of 2 is also a multiple of 4.If a number is a multiple of 2, then it a multiple of 4. False If a num
valentina_108 [34]

Answer:

If a number is a multiple of 2, it may NOT be a multiple of 4. An example would be the number 6.

6\div2=3, but 6\div4=1.5.

However, if a number is multiple of 4, it is guaranteed to be a multiple of 2, since 4 itself is a multiple of 2.

Example:

8\div4=2

This is simply

8\div2\div2=2.

It is a multiple of 2 twice.

deff fn [24]

Answer:

2.7 s  (1 d.p.)

Step-by-step explanation:

Use the <u>Constant Acceleration Equations</u> where:

  • s = displacement in meters
  • u = initial speed in m/s
  • v = final speed in m/s
  • a = acceleration in m/s²
  • t = time in s (seconds)

Given:

  • s = 55 m
  • u = 11.8 m/s
  • a = 6.39 m/s²

\begin{aligned}\text{Using }s & =ut+\dfrac{1}{2}at^2\\\implies 55 & =11.8t+\dfrac{1}{2}(6.39)t^2\end{aligned}

Rearrange the equation to equal zero:

\implies 3.195t^2+11.8t-55=0

<u>Quadratic Formula</u>

x=\dfrac{-b \pm \sqrt{b^2-4ac} }{2a}\quad\textsf{when }\:ax^2+bx+c=0

Use the quadratic equation to solve for t:

\implies a=3.195, \quad b=11.8, \quad c=-55

\implies t=\dfrac{-11.8 \pm \sqrt{11.8^2-4(3.195)(-55)} }{2(3.195)}

\implies t=2.694780675, -6.388051411

As time is <u>positive</u>:

\implies t=2.694780675... \:\text{s}

\implies t=2.7 \: \text{s (1 d.p.)}
