Just hit the "2nd" button on the calculator and find the "asin" key

1×10^4

1 Mile=1,760 yards

7,040 / 1,760 =4 miles.

Because PI are fucking good

There are 3 feet in a yard and 5280 feet in a mile, so let's multiply 7040 by 3 and get 21,120

21120/5280 = 4

Now, we wanted yards, so divide 4 by 3 to get back to yards again. 

There are 1 1/3 miles in 7040 yards.

Just use the distance fromula, rarinstraw

For instance....PQ  = sqrt  [ (2 -1)^2 + (-3-2)^2 ]  = sqrt [1 + 25]   =  sqrt(26)  = RS

QR = sqrt [ (-1 - 4)^2 + (-3 -2)^2]  = sqrt [ 25 + 25]  = sqrt [50]  = 5sqrt(2)  = SP

\(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\begin{pmatrix} 1\\ 2 \end{pmatrix}\)

x/y

Use the backslash as the fraction bar.

No. Here's one: sqrt(-4384)

1.023*10^3/2.8*10^4    we can write this as

(1.023 / 2.8) * (10^3 / 10^4)  =

0.3653571428 * 10^-1 

u/5+3=1    subtract 3 from both sides

u/5  = -2    multiply both sides by 5

u  = -10

Polynomial for v^2-5v+4

v² - 5v + 4 = 0

v(1;2) = - (-5/2) ± √ ((5/2)² - 4)

v(1) = 2,5 + 1,5 = 4

v(2) = 2,5 - 1,5 = 1

v² - 5v + 4 = (v - 4) * (v - 1)

Suppose you have 2 direct ancestors and they have two direct ancestors, How many direct ancestors do you have 10 generations back?

Beginning Amount __2__________

Growth Rate___100%______________

Time Periods_10 generation. A generation is generally taken to be between 20 - 25 years, or between 200 - 250 years. Direct ancestors is 2^10=1,024.________________

Solve for v: v^2-5 v+4 = 0            The left hand side factors into a product with two terms: (v-4) (v-1) = 0 Split into two equations: v-4 = 0 or v-1 = 0 Add 4 to both sides: v = 4 or v-1 = 0 Add 1 to both sides: Answer: | | v = 4                  or              v = 1

She was not nice to me and trust me I was super nice to her. she called me a cat and started bullying be in the messages and said I was an idiot.

 i = sqrt(-1), which is an impossibility because there is no square root of any negative number.

thank you for you help

thank you for you help

The statue is sqrt (13^2  - 12^2)  = sqrt(169 - 144)  = sqrt(25)   = 5 feet taller

she or he is correct

Ok, first, distribute the 2 into a+3

2a+6=-12

Then subtract 6 from both sides.

2a=-18

Lastly, divide by 2.

a=-9

So, a=-9

In a 45-45-90  right triangle, the legs are  1/sqrt(2)  as long as the hypotenuse....

So.....the legs are  3sqrt(2) * (1 / sqrt(2))   =    3  units long

Both legs are equal to 3 because they are congruent and equal 3*(sqrt(2))/sqrt(2).

Reason: 45-45-90 Thrm.

Both legs are congruent, hypotenuse is leg*sqrt(2)
