How do I convert radians to degrees? Is it pi/180 or 180/pi? I get them confused! Thanks

Answers

It could be either one, depending on whether you intend to multiply or divide.

When you convert, just remember that degrees ==> less radians,
and radians ==> more degrees. Then you can always check the
results, and make sure that you used the right conversion factor
in the right direction.

degrees = radians * 180/pi

Which scenario best matches the linear relationship expressed in the equation y = 32x + 80?Joseph has $80 in his bank account and spends $32 each day.
Joseph has $80 in his bank account and earns $32 each day.
Joseph had $32 in his bank account and deposited another $80.
Joseph has $32 in his bank account and earns $80 each day.

Answers

Answer:

Option (2) best matches the given the linear relationship y = 32x + 80

Step-by-step explanation:

Given linear relationship as y = 32x + 80

We have to find the best match from the given options to the given the linear relationship.

1) Joseph has $80 in his bank account and spends $32 each day.

Let the money Joseph spend each day be $x

Since, the amount one spend gets deducted from the money one have.

So, given statement is represented as y = 80 - 32x .

2) Joseph has $80 in his bank account and earns $32 each day.

Let the money Joseph earns each day be $x

Since, the amount one earns gets added to the money one have.

So, given statement is represented as y = 80 + 32x .

3) Joseph had $32 in his bank account and deposited another $80.

Since, he is depositing money in account so it gets add up

So, given statement is represented as y = 32 + 80 = 112

4) Joseph has $32 in his bank account and earns $80 each day.

Let the money Joseph earns each day be $x

Since, the amount one earns gets added to the money one have.

So, given statement is represented as y = 32 + 80x .

Out of all four option, option (2) best matches the given the linear relationship y = 32x + 80

he has 80 in the bank account and earns 32 each day....where x represents the number of days and y represents the total in the account

Answer:

31/20

Step-by-step explanation:

You need to plug in x as y-3.

so instead of 10x+10y=1 it is 10(y-3)+10y=1

Then just simplify the equation to find the value of y

Answers

Adding and subtracting amonomial requires having the same variables. No matter how big or small theircoefficient is, if their variables do not match, they cannot be added or subtracted.The crucial part in adding or subtracting monomials is their sign. If the signsare the same, retain the sign. If the signs are different, subtract and keepthe sign of the larger number.

3x2y + 3xy (cannot be added)
3x2y + (–12x2y) = -9x2y
3x2y + 2x2y2 (cannot be added)
3x2y + 7xy2 (cannot be added)
3x2y + (–10x2) (cannot be added)
3x2y + 4x2y = 7x2y
3x2y + 3x3 (cannot be added)

A boat costs $11,850 and decreases in value by 10% per year. How much will the boat be worth after 8 years?A. $4,590.93

B. $11,770.00

C. $25,401.53

D. $5,101.04

Answers

Answer:

The boat worth is $5101.04 after 8 years .

Option D is correct .

Step-by-step explanation:

The decrease exponential function is written in the form

$y = a (1 - r)^(t)$

Where a is the initial value , r is the rate of interest in the decimal form and t is the time in years .

As given

A boat costs $11,850 and decreases in value by 10% per year .

a = $ 11850

10% is written in the decimal form

$= (10)/(100)$

= 0.10

t = 8 years

Put all the values in the function

$y = 11850(1 - 0.10)^(8)$

$y = 11850(0.9)^(8)$

$y = 11850* 0.430467$

y = $5101.04

Therefore the boat worth is $5101.04 after 8 years .

Option D is correct .

11,850 x .9 = 11,605

11605 x . 9 = 9,598.5   year 2

9,598.5 x .9 = 8,638.65

8,635 x .9 = 7,774.785 year 4

7,774.785 x .9 = 6,997.31

6,6997.31 x .9 = 6297.58   year 6

6297.58 x .9 = 5,667.82

5,667.82 x .9 = 5,101.04 year 8

The answer is D
