Answer:
18.9271 liters
Step-by-step explanation:
i googled it
From the attached graphic:
e = c*h/wavelength therefore,
wavelength = c*h / e
wavelength = 299,792,458 * 6.62606957e-34 / 3.38x10^-19
wavelength = 5.8771e-7 meters
37 over 8 or 37/8. I plugged it in on my calculator and it was correct.
We need to find the product of :
![\mleft(4y-3\mright)\mleft(2y2+3y-5\mright)](https://tex.z-dn.net/?f=%5Cmleft%284y-3%5Cmright%29%5Cmleft%282y2%2B3y-5%5Cmright%29)
So, the result as following:
![\begin{gathered} \mleft(4y-3\mright)\mleft(2y^2+3y-5\mright) \\ =4y\cdot(2y^2+3y-5)-3\cdot(2y^2+3y-5) \\ =8y^3+12y^2-20y-(6y^2+9y-15) \\ =8y^3+12y^2-20y-6y^2-9y+15 \\ \\ =8y^3+6y^2-29y+15 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Cmleft%284y-3%5Cmright%29%5Cmleft%282y%5E2%2B3y-5%5Cmright%29%20%5C%5C%20%3D4y%5Ccdot%282y%5E2%2B3y-5%29-3%5Ccdot%282y%5E2%2B3y-5%29%20%5C%5C%20%3D8y%5E3%2B12y%5E2-20y-%286y%5E2%2B9y-15%29%20%5C%5C%20%3D8y%5E3%2B12y%5E2-20y-6y%5E2-9y%2B15%20%5C%5C%20%20%5C%5C%20%3D8y%5E3%2B6y%5E2-29y%2B15%20%5Cend%7Bgathered%7D)
So, the answer is the option 4. 8y3 + 6y2 − 29y + 15
Y = 90 degrees
1) The angles on a straight line add to 180 degrees so 180-110= 70 degrees.
2) The angles in a triangle add to 180 degrees so 70+70= 140 degrees. The angle at the top of the triangle will have to be 40 degrees as 140+40= 180 degrees.
3) As x is half the angle at the top of the triangle (40 degrees), x will equal 20 degrees.
4) As the angles in a triangle add to 180 degrees 20+70=90 degrees 180-90=90 degrees.
5) Answer = 90 degrees
