IT DOES NOT MATTER YOU WILL NOT BE ABLE TO SOLVE THIS QUESTION
YOU WOULD GET 5x = 2 + 3x^2 AND YOU WOULD STILL NOT BE ABLE TO SOLVE YOU COULD GET 3x^2 = 2 + 5x AND YOU COULD NOT SOLVE.
THE REASON WHY IS BECAUSE YOU HAVE TO HAVE THE SAME X TO ADD THEM OR MINUS THEM< WHICH IN THIS CASE ONE IS REGULAR BUT THE OTHER IS SQUARED. AND ALSO THE TWO NEEDS SOMEONE TO GO WITH< BUT THE IS ONLY ONE OF HIS TYPE SO HE CAN'T.
WELCOME :/
Answer:
y = -0.5(x - 4)^2 + 5.
y = -0.5x^2 + 4x - 3.
Step-by-step explanation:
The vertex is at (4, 5). so we have:
f(x) = a(x - 4)^2 + 5
When x = 0 y = -3 so substituting in the above:
- 3 = a(0-4)^2 + 5
-8 = 16a
a = -0.5.
So the vertex form is y = -0.5(x - 4)^2 + 5.
Standard form:
y = -0.5(x^2 - 8x + 16) + 5
y = -0.5x^2 + 4x - 8 + 5
y = -0.5x^2 + 4x - 3.
Answer:
6^-4 ÷ 3^-4
6^-4/3^-4
Since their powers are negative
Flip them both so the negative index is lost.
It now becomes
3^4/6^4
81/1296
=1/16
Answer:
The area of the sphere in the cylinder and which locate above the xy plane is 
Step-by-step explanation:
The surface area of the sphere is:

and the cylinder
can be written as:


where;
D = domain of integration which spans between 
and;
the part of the sphere:

making z the subject of the formula, then :

Thus,


Similarly;


So;





From cylindrical coordinates; we have:

dA = rdrdθ
By applying the symmetry in the x-axis, the area of the surface will be:





![A = 2a^2 [ cos \theta + \theta ]^{\dfrac{\pi}{2} }_{0}](https://tex.z-dn.net/?f=A%20%3D%202a%5E2%20%5B%20cos%20%5Ctheta%20%2B%20%5Ctheta%20%5D%5E%7B%5Cdfrac%7B%5Cpi%7D%7B2%7D%20%7D_%7B0%7D)
![A = 2a^2 [ cos \dfrac{\pi}{2}+ \dfrac{\pi}{2} - cos (0)- (0)]](https://tex.z-dn.net/?f=A%20%3D%202a%5E2%20%5B%20cos%20%5Cdfrac%7B%5Cpi%7D%7B2%7D%2B%20%5Cdfrac%7B%5Cpi%7D%7B2%7D%20-%20cos%20%280%29-%20%280%29%5D)
![A = 2a^2 [0 + \dfrac{\pi}{2}-1+0]](https://tex.z-dn.net/?f=A%20%3D%202a%5E2%20%5B0%20%2B%20%5Cdfrac%7B%5Cpi%7D%7B2%7D-1%2B0%5D)


Therefore, the area of the sphere in the cylinder and which locate above the xy plane is
