Answer:

8\frac{37}{56}

Step-by-step explanation:

12\frac{2}{7} + 3\frac{5}{8}  = \frac{86}{7}  + \frac{29}{8}  = \frac{688 - 203}{56} = \frac{485}{56}  = 8\frac{37}{56}

Consider the paraboloid z=x2+y2. the plane 4x−8y+z−10=0 cuts the paraboloid, its intersection being a curve. find "the natural"
VladimirAG [237]

4x-8y+z-10=0\implies4x-8y+x^2+y^2-10=0


Complete the square to get


x^2+4x+4-4+y^2-8y+16-16-10=0


(x+2)^2+(y-4)^2=30


Now let


x+2=\sqrt{30}\cos t

y-4=\sqrt{30}\sin t


and the intersection can be expressed as a function of t,


\mathbf r(t)=(\sqrt{30}\cos t-2,\sqrt{30}\sin t+4)


with 0\le t\le2\pi.

luda_lava [24]
The issue here is to express fractions more easily:
2 <span>1/4: 6 3/4
lets simplify fractions:
</span>2 <span>1/4 = 8/4 + 1/4 = 9/4
6 3/4 = 24/6 + 3/4 = 27/6
So the ratio can also be expressed as:
</span><span>9/4 : </span>27/6
lets find a common denominator:
54/24 : 108/24
are also equivalent, so we can reduce:
54 : 108
and finally
1 : 2

Which of the following graphs represent a nonproportional relationship? Select all that apply.
natka813 [3]

Answer:

2nd, 4th and 5th one

Step-by-step explanation:

Hey There!

So remember in order for it to be a proportional relationship it has to be a straight line and it has to go through the origin (0,0)

The 2nd, 4th and 5th ones are non proportional relationships

Why? Well because they don't go through the origin
