Answer: A.) -21

               B.) 14

Step-by-step explanation:

f(-3)=x

A.) f(-3) = 4(-3) - 9

           = -12-9

           = - 21

B.) f(-3) = -1/3(-3) + 13

           = 1 + 13

           = 14

SOLUTION

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Explain the formula to use

Using the cosine rule which states that:

z^2=x^2+y^2-2xy\cos Z

STEP 2: Write the given sides

x=4,y=6,Z=41^{\circ},z=?

STEP 3: Find the value of z

\begin{gathered} By\text{ substitution,} \\ z^2=4^2+6^2-2(4)(6)\cos41 \\ z^2=16+36-48cos41 \\ z^2=52-36.22605985 \\ z^2=15.77394015 \\ z=\sqrt{15.77394015} \\ z=3.971641997 \\ z\approx4.0 \end{gathered}

Hence, the indicated length is 4.0

.At Phil’s work, there are 12 part-time workers and 18 full-time workers. What is the ratio of part-time workers to total worker
Scrat [10]

Answer:

  2/5

Step-by-step explanation:

The desired ratio is ...

  (part-time)/(total) = (part-time)/((part-time) +(full-time)) = 12/(12+18)

  = 12/30 = 2/5

The ratio of part-time workers to total workers is 2 : 5.

What is the value of x and y?
Pavel [41]

Answer:

x=\boxed{2}

y=\boxed{4}

Step-by-step explanation:

\begin{cases} y= 6x-8... (1)\\\\y=-3x+10...(2)\end{cases}

From equations (1) & (2), we find:

6x - 8 = - 3x +10

\therefore 6x+3x = 8+10

\therefore 9x = 18

\therefore x =\frac{18}{9}

\therefore x = 2

Plug x = 2 in equation (1)

y = 6(2)-8 = 12-8 =4

So,

x=\boxed{2}

y=\boxed{4}
