Answer:
2:3:5 = 480:720:1200
(a) 480+720+1200
(b) 480
(c) 720/(a)
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
All I did was find another angle that is around 275 and I got 360. Also D has a number around 360.
9+7x=37
7x=37-9
7x=28
x=28/7
x=4
Answer:
3 - 151 x
Step-by-step explanation:
d/dx(5×3 x - 10×15 x - 3 x - 10 x - (3 x - 3)) = -151
Indefinite integral:
integral(3 - 151 x) dx = 3 x - 75.5 x^2 + constant
Definite integral after subtraction of diverging parts:
integral_0^∞ ((3 - 151 x) - (3 - 151 x)) dx = 0
Answer:
D
Step-by-step explanation:
Set up to different integrals that match the endpoints
so in our case it would look like
![\int\limits^0_{-2} {x} \, dx +\int\limits^1_0 {x+1} \, dx](https://tex.z-dn.net/?f=%5Cint%5Climits%5E0_%7B-2%7D%20%7Bx%7D%20%5C%2C%20dx%20%2B%5Cint%5Climits%5E1_0%20%7Bx%2B1%7D%20%5C%2C%20dx)
now it's just a matter of computing it
![\int\limits^0_{-2} {x} \, dx =x^2\\0^2-(-2)^2=4\\\int\limits^1_0 {x+1} \, dx =\frac{x^2}{2}+x\\\frac{1}{2}+1-0=\frac{3}{2}\\\frac{3}{2}+4=\frac{11}{2}](https://tex.z-dn.net/?f=%5Cint%5Climits%5E0_%7B-2%7D%20%7Bx%7D%20%5C%2C%20dx%20%3Dx%5E2%5C%5C0%5E2-%28-2%29%5E2%3D4%5C%5C%5Cint%5Climits%5E1_0%20%7Bx%2B1%7D%20%5C%2C%20dx%20%3D%5Cfrac%7Bx%5E2%7D%7B2%7D%2Bx%5C%5C%5Cfrac%7B1%7D%7B2%7D%2B1-0%3D%5Cfrac%7B3%7D%7B2%7D%5C%5C%5Cfrac%7B3%7D%7B2%7D%2B4%3D%5Cfrac%7B11%7D%7B2%7D)
