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)

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

Diane works at a gardening store, and today she is helping assemble gas trimmers to be sold. An employee from an earlier shift a

Oxana [17]

The linear function for the number of trimmers assembled is:

y = 7 + 4x.

--------------------------------

A linear function has the following format:

$y = ax + b$

In which:

a is the rate of change.
b is the fixed amount.

--------------------------------

In an earlier shift, 7 trimmers had already been produced, thus 7 is the fixed amount, that is, $b = 7$ .
Diane assembles 4 trimmers per hour, thus the rate of change is 4, that is, $a = 4$
The <u>amount of trimmers y produced after x hours</u> is given by:

$y(x) = 4x + 7$
