Answer:
A
Step-by-step explanation:
The correct divisor is 2. You change the sign of the real number without a variable when that real number is the divisor.
So - 2 becomes 2 and C and D are both incorrect.
The 0 comes between - 2 and 4 because the x term is 0x. (there isn't one).
That makes B wrong.
The answer is A
Answer:
34.3
Step-by-step explanation:
To multiply just convert the 49 into a decimal like this -> 49.0 x 0.7 = 34.3
I assume the cone has equation 
(i.e. the upper half of the infinite cone given by 
). Take
The volume of the described region (call it 
) is
The limits on 
and 
should be obvious. The lower limit on 
is obtained by first determining the intersection of the cone and sphere lies in the cylinder 
. The distance between the central axis of the cone and this intersection is 1. The sphere has radius 
. Then satisfies
(I've added a picture to better demonstrate this)
Computing the integral is trivial. We have
To solve this we need to form 2 equations with only 2 variables.
x+4y-5z=-7
2x+y+5z=8
3x+5y=1
15x+10y+15z=35
6x+3y+15z=24
9x+7y=11
Now we need to use these to find x and y
9x+15y=3
9x+7y=11
8y=-8
y=-1
Therefore:
x=2
From this we can find that:
2(2)-1+5z=8
Therefore z=1
The answer is x=2, y=-1, z=1
Answer:
Hello
Step-by-step explanation
3 3/4 goes first on the left side then 3 1/4, 2 3/4,
2 1/2 ,1 3/4, 1 1/4, 1, 2, 3
Hope this helps
