Try it as follows:

Numerator 

sqrt(64,5) → sqrt(2*32,5) → sqrt(2,5)*sqrt(32,5) → sqrt(2,5)*sqrt(2^5,5) → sqrt(2,5)*2

sqrt(2,5) is 2^(1/5), so sqrt(64,5) → 2*2^(1/5)

Hence sqrt(64,5)*2^(-1/5) → 2*2^(1/5)*2^(-1/5) → 2

Denominator

sqrt(8) → (sqrt(2)*sqrt(4)) → 2*sqrt(2)

Numerator/Denominator → 1/sqrt(2)

Raise this to the power -4:   (1/sqrt(2))^-4 → sqrt(2)^4 → (sqrt(2)^2)^2 → 2^2 → 4

I think the following is probably what is needed (but you should check it carefully!).

Note:  The force on top of BE should be labelled R_E not R_D (which was a typo by me).  It will be the same in magnitude as R_B. 

.

Very well, now for member BE what is Rd and Rb ? 

If you are asking about how to use matrices on the home page calculator here, then the answer is that that function seems to be unavailable currently (it was available some time ago!).

Otherwise, just go ahead and ask your matrices question.

The hyperbolic sine (pronounced "shine", though spelled as "sinh") is defined as:

sinh(x) = (e^x - e^-x)/2 

Thank You CPhill for the answer.   :)

0.03x-0.6=2.4      multiply through by 100 to clear the decimals

3x - 60 = 240     add 60 to both sides

3x = 300    divide both sides by 3

x = 100

Since Linda arrived at 12:35pm and left at 8:50am, her flight was:

12:35 - 8:50=3:45 hours, which was Linda's flight. Note that usual subtraction doesn't work here, so we use "clock arithmetic".

Since it took her another half an hour to get home, so we just add arrival time plus 30 minutes=12:35 + 30=1:05pm, when Linda arrives home.

Note: You could do ordinary subtraction but have to convert the minutes into decimals by dividing them by 60. So 12:35 becomes 12 +35/60=12.5833 - 8 + 50/60=8.8333=3.75.But since an hour has 60 minutes, then .75 X 60=45 minutes.

Post your question in the "Ask New Question" section, but NOT here. This is the "Answers" section.

Lindas flight left chicago at 8:50am and arrived in nassaua at 12:35pm the same day. 

 a. how long was her flight .

it took another 1half hour before she finaly arrived at her home.

b. at what time did she arrived home

A certain brand of peanut butter comes in jars of two sizes. The larger jar  is 32 ounces and sells it for 2.99 while the smaller jar is 18 ounces and sells for 1.59 .Calcualte and sate which is better

2.99/32=.0934375 cost per ounce of the larger jar.

1.59/18=.088333 cost per ounce of the smaller jar.

Therefore the smaller jar is cheaper and better deal. In fact, it is cheaper by about 5.5%

4+4=8

-2^(-4) Is that what you want? If so, then:

= - 1/16

65+0.10x=73.40  subtract 65 from both sides

.10x = 8.40     multiply both sides by 100 in order to clear the decimals

10x = 840       divide both sides by 10

x = 84

65+0.10x=73.40 What is the value of x?

.10x=73.4 - 65

.10x=8.4

x=8.4/.1

x=84

what does -20 over -13 reduce to?

-20/-13=20/13

=1 7/13

The answer is 4

how do you get it?

A box of blueberries is 2/5 full. Stella and her friends each ate 1/10 of the blueberries. How many people ate blueberries

Because Stella and her friends EACH ate 1/10 of the blueberries, that means there were 10 people who ate the blueberries.

10^6-10^4=10^2  That is NOT true! It is only true when you divide like this:

10^6/10^4=10^2 You subtract exponents when you DIVIDE. You ADD exponents when you MULTIPLY.

what is 2+2 equal?

=4 which is your answer.

The sine MUST be between +1 and -1

What is 2 to the millionth power?   

It is a very, very, very BIG NUMBER!!. It has 301,030 digits long!.If you were to print it on an ordinary paper, you would need about 150 pages of paper. It begins with: 9900656...........and so on.

-3/4 + p = 1/2 move all the numbers to one side and change the sign + or -, like this:

p=1/2 +3/4 Now you have to find the smallest common denominator, which is 4 in this case, so

p=2/4 +3/4, Now we just add the two top numbers, like this:

p=5/4=1 1/4 which is your answer.

x=20

rounding to the 10th place

For example: 10.123456, so rounding to the 10th place will look like this:

10.1 rounded to the 10th place

10.12 rounded to the hundredth place

10.123 rounded to the thousandth place...........and so on.
