Find the value of each variable.

insens350 [35]

Step-by-step explanation:

11)

x= 5

${y}^{2} = 2 \times {5}^{2} \\ {y}^{2} = 50 \\ y = 5 \sqrt{2}$

12)

$\tan(30 ) = \frac{9}{y} \\ y = \frac{9}{ \tan(30) } = 9 \sqrt{3} \\ {x}^{2} = {9}^{2} + {(9 \sqrt{3} )}^{2} \\ {x}^{2} = 324 \\ x = 18$

13)

$\sin(60) = \frac{x}{22} \\ x = 11 \sqrt{3} \\ \cos(60) = \frac{y}{22} \\ y = 11$

14)

${16}^{2} = {x}^{2} + {y}^{2} \\ x = y \\ {16}^{2} = 2 {x}^{2} \\ x = 8 \sqrt{2} \\ y = 8 \sqrt{2}$

15)

$\tan(30) = \frac{x}{42} \\ x = 14 \sqrt{3} \\ \cos(30) = \frac{42}{y} \\ y = \frac{42}{ \cos(30) } \\ y = 28 \sqrt{3}$

16)

${(19 \sqrt{2}) }^{2} = {x}^{2} + {y}^{2} \\ x = y \\ 722 = 2 {x}^{2} \\ {x}^{2} = 361 \\ x = 19 \\ y = 19$

Hey can you please help me posted picture of question

Common factor is such a term which can be taken out common from each term of the expression.

If you observe the given expression, 2x can be taken out common leaving the expression which cannot be factored any further.

14x² - 12x
= 2x (7x - 6)

So 2x is the common factor. The answer to this question is option C

F(n)=64+6n what is the recursive formula of f(n)?

Ghella [55]

Answer:

Step-by-step explanation:

f(n)=64+6n

f(n-1)=64+6(n-1)=64+6n-6=f(n)-6

f(n-1)+6=f(n)

or f(n)-f(n-1)=6
