If we  have a unit circle......x  =  -sqrt (1 - (4/5)^2 )   =  -sqrt ( 25/25 - 16/25)   = - sqrt (9/25)   = -3/5

[Remember, x is negative in the 2nd quadrant ]

So

sin(t ) = y/r =  (4/5) / 1   = 4/5

cos (t)  = x / r  =  (-3/5)/ 1 = -3/5

tan(t)  = y/x =  [4/5] / [-3/5]   = [4/5] * [ -5/3]  = -4/3

sec (t)  = reciprocal of cos (t)  =  -5/3

You have to know at least ONE ANGLE and ONE SIDE.

0.51, next time, use a calculator 

No. They are used for ALL triangles.

[Old value - New value] / Old value X 100=% change.

How do I write 0.0082515398387924 in scientific notation?=8.2515398387924 X 10^-3

0.51

what is the solution to 1830000 X [1-1/(1.09)^10/.09]=-6.7590... X 10^6

E stands for "exponent" or "power of 10".

   .000415E-3= 4.15 × 10^-7

I'm not positive but I'm pretty sure it's 0 because 0 over anything is 0 but since ou cant devide anything by 0 it could be indefinate but since you're deviding 0/0 it's most likely 0

4, and go to school.

Let P be the total population.....and 15%  = .15  ....  and "of" means "multiply"....so we have

.15 P  = 2100   divide both sides by .15

P = 14000

15/100 * x = 2100 

.15x=2100 divide both sides by .15

x=2100 / .15=14,000 people in Brenham.

9+10=19.

anwsered by ariana akizian 9+ 10 = 19

you could even check this anwser on the caluclator on this website

2376 / 8  = 297 miles

2 / sqrt (2)  =

[sqrt(2) * sqrt(2) ] / sqrt(2)  =

sqrt(2)   which is irrational

24% of $184.50=24/100 X 184.5=$44.28

If you wanted the same difference between the terms, then:

A=21, B=28, C=35

Because, we can always multiply either the top/bottom of any fraction by 1 without changing it's value....so.......3   =  1 * 3      ......so.......

[1 * 3] / [ 3 * 3 * 3]   =  [1 ] / [3 * 3]  =  1/9

Your question dosen't make sense.

What is cost per ounce if the price is .44 and there is 8oz in the can?

.44 / 8=.055, or five and a half cents per ounce.
