X is 8 y is 6 , sin (y/r) r=10. x^2+y^2 = r^2. cos(x/r) tan (y/x) the other 3 are probably cosecant secant and cotangent just do the inverse (flip them) r/x etc..
Answer:
(2x² + 3y)(4
- 6x²y + 9y²)
Step-by-step explanation:
A sum of cubes is factored in general as
a³ + b³ = (a + b)(a² - ab + b²) , thus
8
+ 27y³
= (2x²)³ + (3y)³ with a = 2x² and b = 3y
= (2x² + 3y)((2x²)² - 2x²(3y) + (3y)²)
= (2x² + 3y)(4 - 6x²y + 9y²)
The equation used to find surface area of a sphere is A=4 pi radius sqaured
So i believe the surface area is <span>314.16. In terms of pi thats 100pi</span>
X represent the smaller number and
represent the larger number
firts lets see how many dollars she has
192 divided by 4 is 48 so she currently has 48 dollars.
and she puts in 2 quarters daily
so lets see how much she need to earn
75 - 48 is 27
lets see how many quarters she need to have 27 dollars 27 x 4 is 180
now lets divide 180 by two because shes giving two everyday. 180 divided by 2 is 54 so if she kept adding two quarters everyday it would take her 54 days to get the rest of the money she need to by and iPod.
i dont know if this helped or not but i solved it
