Answer:

the quadrilateral is a rhombus as its all four sides are equal (of 4cm) each

Area of rhombus = 1/2 (digonal 1 × digonal 2)

= 1/2 ( 7×6 )

= 1/2 ( 42)

= 21

hence area of quadrilateral is 21 cm square

Write 56 as a product of primes. Use index notation when giving your answer.

mixas84 [53]

Answer:

56 as a product of primes using index notation is: $\mathbf{2^3 \times 7}$

Step-by-step explanation:

We need to write 56 as a product of primes.

Prime Numbers:

Numbers that are divisible by 1 or itself.

Now, writing 56 as product of primes

56 = 2 x 2 x 2 x 7

Now, Use index notation when giving your answer.

Index Notation:

Express elements in power form i.e. if we have 2 x 2 we can write it as 2^2

So, answer will be:

$56 = 2 \times 2 \times 2 \times 7$

$=2^3 \times 7$

So, 56 as a product of primes using index notation is: $\mathbf{2^3 \times 7}$

Last year, a beauty magazine had a total of 2,650 subscribers. This year, after its parent company made some changes, it had 3,2

lilavasa [31]

Answer:

22%

Step-by-step explanation:

Divide 2,650 by 100:

2,650/100=26.5

Then divide 3233 by the dividend:

122=122%

Now you can see that there is a 22% percent increase over 100%, theefore making our answer 22%.

Dont answer this question if you dont know the answer

$\huge\boxed{♧ \: \mathfrak{ \underline{Answer} \: ♧}}$

here's the solution,

$\pi = 180$

$\dfrac{\pi}{3} = \dfrac{180}{3}$

$\dfrac{\pi}{3} = 60$

=》

$f( \theta) = \cos( \theta) + 2 \cos( \frac{ \theta}{2} )$

=》

$f(60) = \cos(60) + 2 \cos( \frac{60}{2} )$

=》

$f(60) = \dfrac{1}{2} + 2 \cos(30)$

=》

$f(60) = \dfrac{1}{2} + (2 \times \frac{ \sqrt{3} }{2})$

=》

$f(60) = \dfrac{1}{2} + \sqrt{3}$

=》

$f(60) = \dfrac{1 + 2 \sqrt{3} }{2}$

hence, correct option is C.
