Is 10+ √42 rational?

Answers

Answer 1

Answer:

This not a rational... means answer is false

Step-by-step explanation:

Answer 2

Answer:

No.

Step-by-step explanation:

Rational numbers can be rewritten as fractions or have a terminating decimal.

We see that √42 will be a never ending decimal. Therefore, the entire expression would become irrational.

Answers

Answer:

1) y=1/5x +0.8

2) y= -2x +10

Step-by-step explanation:

It's been a while, but I think this is right:

1)

For 2 lines to be parallel they must have the same slope

Recall that the equation of a line is

y-y1 = m (x- x1)

m being slope

So looking at equation 1, we can tell that the slope is 1/5 because it has already been distributed to the x.

So we know our equation will look something like this

y-y1 = 1/5 (x- x1)

We also know that the line passes through the point (8,1)

So, you plug in those points to your equation

y- 1 = 1/5(x - 8)

Simplifying and distributing the equation, we end up with

y= 1/5x + 0.8

(if you would like me to explain the simplification plz ask in a comment.)

2)

First you have to move -x from the left side of the equation to the right, making the equation

2y= x+10

then divide by 2 on both sides (im writing x/2 as 1/2x, because they are the same)

y= 1/2x + 5

For 2 lines to be perpendicular they must have the opposite reciprocal slope

Meaning if you had a slope of 2, the opposite would be -2 and the reciprocal would be 1/2, so your slope would be -1/2

Knowing this and keeping in mind our equation of a line from the first question, our slope of a perpendicular line (or m in our equation) of y= 1/2x + 5

would be -2

So far we have an equation that looks like

y-y1 = -2 (x- x1)

So now we plug in our points (6, -2)

(y- -2)

y + 2 = -2 (x - 6)

Simplifying and distributing the equation, we end up with

y= -2x +10

(if you would like me to explain the simplification or have a question don't hesitate to ask in a comment.)

Answer:  1.)  y = 1/5 x - 3/5

2.) y = -2x + 10

Step-by-step explanation:

1.)  Keep the same slope. Substitute the y and x-values from the given coordinate into the slope-intercept form and solve for the new b

1 = 1/5(8) + b    1 = 8/5 +b .subtract  8/5 form both sides:

-3/5 = b

y = 1/5 x - 3/5

2.) Rewrite the given equation in slope-intercept form

-x + 2y = 10  becomes y= 1/2 x +10

Take the reciprocal of the slope and reverse the sign:  1/2 becomes -2

Substitute the y and x-values from the given coordinate into the slope-intercept equation and solve for b.

-2 = -2(6) + b

-2 = -12 + b   Add +12 to both sides

10 = b

y = -2x + 10   Standard form: 2x + y = 10

Say you own 5,715 shares of Sanden Research Labs, each of which pays a yearly dividend of $14.66. How much do you receive in dividends every year? a. $83,781.90 b. $81,729.50 c. $75,865.50 d. $93,954.60

Answers

Answer:

$83,781.90

Step-by-step explanation:

Dividend received each year is $83781.9

What is Algebra?

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

Given;

Number of shares= 5715

Yearly dividend of each share= $14.66

Now,

Total dividend of all shares

=5715*14.66

=83781.9

Therefore, by algebra the dividend will be $83781.9

Diego pays $4.50 for 3 pound of bananas and 2 pounds of oranges. One pound of oranges costs $0.75 more than one pound of bananas. Let b represent the price per pound of bananas . which equation represents the situation, and what is the price per pound of each fruit?

Answers

Answer:

D. 3b + 2(b + 0.75) = 4.50; $0.60 per pound of bananas, $1.35 per pound of oranges

Step-by-step explanation:

Price per pounds of bananas = b

Price per pound of oranges = b + $0.75

Diego buys:

3 pounds of bananas = 3(b) = 3b

2 pounds of oranges = 2(b + 0.75)

Amount paid by Diego is expressed as:

3b + 2(b + 0.75) = 4.50

To find the price per pound of each fruit, use the equation above to find the value of b:

3b + 2b + 1.50 = 4.50

Combine like terms

5b + 1.50 = 4.50

5b + 1.50 - 1.50 = 4.50 - 1.50

5b = 3

5b/5 = 3/5

b = 0.6

Price per pound of banana = b = $0.6

Price per pound of oranges = b + $0.75

Plug in the value of b

= $0.6 + $0.75

= $1.35

What is the future value of the loan in the previous problem if the interest is compounded
monthly (all other conditions remain the same)?

Answers

Answer:Your calculator should now display a screen with these variables. I have written what each

variable stands for next to the variable. You calculator likely has numbers next to some of the

variables. This is okay. We will type over them when we need to solve a specific loan problem.

N Number of payments

I% Annual interest rate

PV Loan amount (Normally

entered as a POSITIVE

number in loan problems.)

PMT Monthly payment amount

(Usually entered as a

NEGATIVE number in loan

problems.)

FV Balance when loan is paid

off. (Usually 0 in a loan

problem.)

P/Y Number of payments per

year. (Usually 12 in a loan

problem.)

C/Y How often interest is

charged. (Usually 12 in a

loan problem)

Begin / End Choose Begin if you make a

loan payment the day you

take your loan. Otherwise

choose End. We will always

leave this on END.

Example: A new car is purchased and a $25,000 loan is taken. The loan is for 6 years (72

months) and the interest rate is 4.9% compounded monthly. What is the monthly payment?

Calculator steps: Hit APPS button then select Finance then select TVM solver.

We will solve most of the problems in this chapter from this screen. We need to know what

each variable represents. We will enter values for every variable except for the one we are

solving for. We are computing a monthly payment. We will put values in for every variable,

except (PMT). PMT stands for the payment.

Enter these values on your calculator.

N (number of payments) 72

I% (annual interest rate) 4.9

PV (Loan amount, make

this amount positive.)

25000

PMT Move cursor here and hit

green alpha button then

enter after you have entered

every other value.

FV (what you owe after

make all payments)

0

P/Y (payments per year) 12

C/Y (how often interest is

paid)

12

Begin / End

(We will always leave this

on end.)

End

Once you have entered all of the amounts scroll up to PMT. Make sure your cursor is flashing

next to PMT. It doesn’t matter what value is in the PMT. Your calculator will put in the correct

payment when you tell it to compute the payment. Hit the green ALPHA button the ENTER.

4. A room measures 10 meters by 15 meters. How many 30 centimeters by 30 centimeters squares of carpet are needed
to cover the floor of this room?​

Answers

Answer:

1667 carpets.

Step-by-step explanation:

For this problem we have to find the

area of room,

area of 1 carpet.

Then we have to find how many such carpet's sum will be equal to area of room.

_______________________________________________

area for rectangle is given by = length * width

area of room = 10 m * 15 m = 150 m. sq.

dimension of carpet = 30 cm * 30 cm

lets converts first 30 cm in meter so that dimension of room and carpet are in same unit that is in meters

100 cm = 1 meter

30 cm = 1/100 * 30 meters = 0.3 meters

area of 1 carpet = 0.3 m * 0.3 m = 0.09 m. sq.

let there be need of x carpet to cover the floor of room.

area of x carpet = area of 1 carpet *x

area of x carpet =0.09x m. sq.

area of x carpet = area of room

0.09x m. sq. = 150 m. sq.

x = 150/0.09 = 1666.67

Thus, there will be need of 1666.67 carpets but carpets cannot be in fraction

hence rounding the number of carpet to nearest whole number.

there will be need of 1667 carpets.
