Answer:

Step-by-step explanation:

cos(t) + i * sin(t) = e^(i * t)

Therefore, (cos(t) + i * sin(t)) / (cos(s) + i * sin(s)) = cos(t - s) + i * sin(t - s)

9 * (cos(135) + i * sin(135)) / (7 * (cos(10) + i * sin(10))) =>

(9/7) * (cos(135 - 10) + i * sin(135 - 10)) =>

(9/7) * (cos(125) + i * sin(125))

Tracy sells water at a fair in 17oz bottles or 11oz cans. If on one shelf she has 11 containers of water that hold a total of 15

blondinia [14]

Answer:

Number of bottles = 6

Number of cans = c

Step-by-step explanation:

Given that:

Container for selling water :

17 oz bottle

11 oz can

Let number of bottles = b

Number of cans = c

b + c = 11 - - - (1)

17b + 11c = 157 - - - (2)

b = 11 - c

Substitute into (2)

17(11 - c) + 11c = 157

187 - 17c + 11c = 157

187 - 6c = 157

-6c = 157 - 187

-6c = -30

c = 30/6

c = 5

From ; b = 11 - c

b = 11 - 5

b = 6

Hence,

Number of bottles = 6

Number of cans = c

DIA [1.3K]

Answer:

A. x = 5

Step-by-step explanation:

3x + 9 = 24

→ Minus 9 from both sides

3x = 15

→ Divide both sides by 3

For each graph below, state wether it represents a function.

Paul [167]

Answers:

Row 1: No, No, No

Row 2: Yes, Yes, Yes

===============================

Explanation:

Use the vertical line test. If it is at all possible to draw a single vertical line through more than one point on the relation curve, then the relation is not a function. This is because a function is only possible when any x input leads to exactly one y output.

So that's why graphs 1,2,3 are not functions, while graphs 4,5,6 are functions.

I HAVE 5 MIN TO TURN THIS IN!!!! PLEASE HELP ME!!!<br> IT'S IN THE IMAGE BELOW

Mariulka [41]

Answer:

<h3>a. x = 8 years</h3><h3>b. 52,000</h3><h3 />

Step-by-step explanation:

company A = 28,000 + 3,000 (x)

company B = 36,000 + 2,000 (x)

where x = no. of years.

<u>company A = company B</u>

28,000 + 3,000 (x) = 36,000 + 2000 (x)

3,000 (x) - 2,000 (x) = 36,000 - 28,000

1,000 (x) = 8,000

x = <u>8,000</u>

1,000

<h3>x = 8 years</h3>

plugin value of x = 8 into company A and B

company A = 28,000 + 3,000 (8)

<h3>company A = 52,000</h3>

company B = 36,000 + 2,000 (8)

<h3>company B = 52,000</h3>

/= fraction sign

3.6 hours

Step-by-step explanation:

Blake can do work in hours = 9

Blake can do a part of work in 1 hour = 1/9

Ned can paint the same room in six hours.

Ned can do a part of work in 1 hour = 1/6

They can do a part of work together in 1 hour = 1/9+1/6

= 5/18

Now they can do 5/18} part of work in hour = 1

So, they can do whole work in hours = 1/5/18

= 3.6

Hence it will take 3.6 hours to paint the room if they work together.
