Answer:

cosec x

Step-by-step explanation:

\cos  x \:  \cot x +  \sin  x \\  \\  = \cos  x  \times  \frac{\cos  x }{ \sin  x }  +  \sin  x   \\  \\  = \frac{\cos^{2}  x +\sin^{2}  x }{ \sin  x }  \\  \\  = \frac{1}{ \sin  x }  \\  \\  = cosec x \\  \\   \red{ \boxed{ \bold{\therefore \:  \cos  x \:  \cot x +  \sin  x = cosec \: x}}}

Answer:

The solution is obtained by dividing the number of flowers by the number of vases.

Let's look at the question again.

Although we do not have all the quantities, we can still show how to solve the problem.

Let x be the total  number of flowers.

There are 4 vases.

Therefore, the number of flowers in each vase will be:

x/4

Flow the same rule for similar problems.

How to solve. Y=-4(x-2)squared+4
Amiraneli [1.4K]
What do you mean, "solve"?
y = -4(x-2)² + 4 
the line is a parabol with a maximum (2;4)
it's roots are  -4(x-2)² + 4  = 0 => (x-2)² = 1 => x-2 = 1 => x = 3
                                                              => x-2 = -1 => x = 1 
symetrical axe: x = 2
is that all you need?

Option B) (x + 3)^2 − 5 is the correct answer

Step-by-step explanation:

Given expression is:

x^2+6x+4

We will solve eah expression in the options to chek which is equivalent to given expression

So,

<u>A) (x + 3)^2 + 5</u>

(x + 3)^2 + 5 = x^2+6x+9+5 \\= x^2+6x+14

NOT equivalent

<u>B) (x + 3)^2 − 5</u>

(x + 3)^2 − 5 = x^2+6x+9-5\\= x^2+6x+4

Equivalent

Hence,

Option B) (x + 3)^2 − 5 is the correct answer
