Which set of coordinates follows these two rules x coordinate start with 4 and add 4 to each term y coordinate start with 4 and multiply each term by 2

A (4, 4), (8, 8), (12, 16)
B (4, 4), (8, 8), (16, 16)
C (4, 4), (6, 16),(8, 64)
D (4, 4), (16,2), (64,0)

Answers

Answer:

A; (4,4), (8,8) and (12,16)

Step-by-step explanation:

The value x starts with 4 and add 4 to each term

The value y start with 4 and each term next is multiplied by 2

So for x, we have;

4 , (4 + 4) and (4 + 4 + 4)

= 4,8 and 12

For y;

we have ;

4, (4 * 2) , (4 * 2 * 2)

= 4, 8, 16

so pairing up, we have;

(4,4), (8,8) and (12,16)

Given that sinФ = 8/17 and cos Ф < 0:

In which quadrant does the terminal side lie when it is placed in standard position?

What is the value of CosФ? CosФ =

What is the value of tanФ? TanФ =

Answers

Answer:

1) The terminal side lies in quadrant 2

2) cosФ = -15/17

3) tanФ = -8/15

Step-by-step explanation:

1) First, we should realize that since sinФ = 8/17, it is positive. Thus, Ф must be in quadrants 1 or 2. And since cosФ is negative, Ф must be in quadrant 2 because cos, sin, and tan are all positive in quadrant 1

2) Next, we must realize that the sides given are a 8-15-17 right triangle. And in this case, since sinФ = 8/17, cosФ should be 15/17. But since cosФ is negative, cosФ = -15/17

3) Lastly, tanФ is opposite/adjacent. Since opposite of Ф is 8 and adjacent of Ф is 15, then tanФ should be 8/15, but since Ф is in quadrant 2, then tanФ is -8/15

A combined total of $53,000 is invested in two bonds that pay 2% and 8.5% simple interest. The annual interest is $3,335.00. How much is invested in each bond? The amount invested at 2% is $ The amount invested at 8.5% is $

Answers

Answer:

8.5 = $35,000

2% = $18,000

Step-by-step explanation:

two equations can be derived from the question

x + y = $53,000 equation 1

0.02x + 0.085y = $3,335.00. equation 2

x = amount invested in 2% bond

y =  amount invested in 8.5% bond

multiply equation 1 by 0.02

0.02x + 0.02y = 1060 equation 3

subtract equation 2 from 3

0.065y = 2275

y = 35,000

substitute for y in equation 1

53,000 - 35,000 = 18,000

Step-by-step explanation:

(9)

The given angles are vertical and congruent , then

2x + 10 = 60 ( subtract 10 from both sides )

2x = 50 ( divide both sides by 2 )

x = 25

(10)

The given angles are vertical and congruent , then

2x + 6 = 100 ( subtract 6 from both sides )

2x = 94 ( divide both sides by 2 )

to accomplish this they mulitpied both sides of the fraction

after that they mulitplied what was in the numerator and combined like terms

Answer:

The answer is 9/10

Step-by-step explanation:

8/10 is the same thing as ⅘, ⅘ is just simplified

⅖ is less than ⅘ so it would come before c

6/5 is more than 1 so it wouldn’t be on that number line.

Answer:

OK.

My answer is based on 2 things.

1. That the furthest point on the left is 0( That other little distance is ignored)

2. That the point C is equidistant from 4/5 and 1.

If so..

Then

4/5 + x + x =1

4/5 +2x = 1

2x= 1-4/5

x=1/10

Now

From 4/5 to C is x...

Then Position C would be

4/5 + 1/10

c= 9/10

Or by simply making guesses...

All Other options are greater than 1... So It can't be those cos C is less than 1

Find the value of x and each arc measure.

12 and 13 please

Answers

Answer:

See answers below;

Step-by-step explanation:

Find the diagram attached

12) Given the following

m<EF = 3x - 6

m<GF = 15x - 30

From the diagram, arcEf and arcGF are supplementary. Hence;

arcEF + arcGF = 180

3x - 6 + 15x - 30  = 180

18x - 36 = 180

18x = 180 + 36

18x = 216

x = 216/18

x = 12degrees

arcEF = 3x-6

arcEF = 3(12) - 6

arcEF = 36 - 6

arcEF = 30degrees

arcGF = 180 - aecEF

arcGF = 180 - 30

arcGF = 150degrees

Since arcDE = arcGF (vertical angles), hence arcDE = 150degrees

arcDFG = arcDG+arcGF

arcDFG = 30 + 150

arcDFG = 180degrees

13) arcMN = arcQP (vertical angles)

12x-5 = 6x+3

Collect like terms

12x - 6x = 3 + 5

6x = 8

x = 8/6

x = 1.3

arcMN =12x - 5

arcMN = 12(8/6) - 5

arcMN = 16 - 5

arcMN = 11degres

arcNP = 180 - arcMN

arcNP = 180 - 11

arcNP = 169degrees

Since arcNQP lies on straight line, hence arcNQP is 180degrees

He closed all banks for four days in order to check their health and restore consumer confidence, and he worked with Congress to pass legislation that protected deposits and gave the Fed greater regulatory power.
