  • Time period=0.5s
  • No if oscillations=20

\\ \sf\longmapsto Time\:period=\dfrac{Time\:taken}{No\:of\; oscillations}

\\ \sf\longmapsto Time\:taken=No\:of\: oscillations (Time\: period)

\\ \sf\longmapsto Time\:taken=20(0.5)

\\ \sf\longmapsto Time\:taken=10s

<h2><u>Given</u> :</h2>

  • Time period = 0.5s
  • Number of oscillations = 20

<h2><u>What </u><u>To </u><u>Find</u> :</h2>

  • Time taken to complete 20 oscillations.

<h2><u>Formula </u><u>Using</u> :</h2>

\begin{gathered} {\underline{\boxed{ \rm {\red{Time \:  period \:  =  \: \frac{Time  \:  \: taken}{Number \:  of \:  oscillations}  }}}}}\end{gathered}

\begin{gathered} {\underline{\boxed{ \rm {\purple{Time  \: taken \:  =  \: Number  \: of \:  oscillations \: (Time \:  period)}}}}}\end{gathered}

<h2><u>Solution</u> :</h2>

\large \rightarrow \:  {\rm {{{\color{orange}{Time  \: taken \:  =  \: 20 (0.5)}}}}}

\large \rightarrow \:  {\rm {{{\color{orange}{Time  \: taken \:  =  \: 10s}}}}}

a. 9/10

explanation:

• the denominators (bottom number) are the same so there is no need to change to a common factor

• because the fractions have common factors, you add the top numbers (3+6) to get 9

• then you put the top number over the 10 (9/10) and it’s simplified as much as possible

b. 3/4

explanation:

• each denominator (bottom term) is a factor of 12 so you have to change each fraction to #/12

• to change 1/3, you multiply the top and bottom numbers by 4 (1x4 & 3x4 = 4/12)

• to change 1/4, you multiply the top and bottom numbers by 3 (1x3 & 4x3 = 3/12)

• to change 1/6, you multiple the top and bottom numbers by 2 (1x2 & 6x2 = 2/12)

• then you add each of the top numbers (4+3+2) and put it over the common denominator (12) to get 9/12

- both 9 & 12 are divisible by 3, so you simply by dividing both by 3 to get 3/4

c. 1/3

explanation:

•the denominators are the same, so you subtract 5-3 without changing the denominator & you get 2/6

• then, because both numbers are divisible by 2, you divide both by 2 and get 1/3

Answer: (x−2)(x−2)

The middle number is -4 and the last number is 4.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get -4

Multiply together to get 4

Can you think of the two numbers?

Try -2 and -2:

-2+-2 = -4

-2*-2 = 4

Fill in the blanks in

(x+_)(x+_)

with -2 and -2 to get...

(x-2)(x-2)

Answer:

(x−2)(x−2)

so the answer is D.
