Answer:
1126.4
Step-by-step explanation:
5.97 x 1024 =6113.28
4.87 x 1024= 4986.88
6113.28-4986.88 =1126.4
Answer:
x = -4, v = 2.5
x = -14, v = -2.5
Step-by-step explanation:
I am a bit confused with the beginning part of the question. From what I understand, you are trying to solve for x and then plug x into the top equation to find the value for V. I am sorry if that is not what you are looking for. If it is, look below!
x + 9 = 5
x = 5 -9
x = -4
v(x + 9)2 = 25
v(-4 + 9)2 = 25
v(5)2 = 25
v(10) = 25
v = 25/10
v = 2.5
x + 9 = -5
x = -5 -9
x = -14
v(x + 9)2 = 25
v(-14 + 9)2 = 25
v(-5)2 = 25
v(-10) = 25
v = 25/(-10)
v = -2.5
I hope this helped! If not, I am sorry. :(
Expression
(5+3)+(5x2)=p
Solution
18
(Step-by-Step)
In this expression we simply have to use basic PEMDAS (Parenthesis Equation Multiplication Division Addition Subtraction) Order.
We start by working out the parenthesis
5 + 3 and 5 x 2
First let's work out our metal and wood paperweights
5+3=8
Simple enough, we have 8 metal AND wood paperweights
Now we have to work out our glass paperweights.
We have twice as many glass as we do metal PW's meaning we need to multiply the 5 metal paperweights by 2
5x2=10
This simplifies and boils our equation down to
8+10
simply solve and add the two and you have your answer
18
The normal vectors to the two planes are (3, 3, 2) and (2, -3, 2). The cross product of these will be the direction vector of the line of intersection, (12, -2, -15).
Using x=0, we can find a point on this line by solving the simultaneous equations that remain:
... 3y +2z = -2
... -3y +2z = 2
Adding these, we get
... 4z = 0
... z = 0
so the point we're looking for is (x, y, z) = (0, -2/3, 0). This gives rise to the parametric equations ...
- x = 12t
- y = -2/3 -2t
- z = -15t
By letting t=2/3, we can find a point on the line that has integer coefficients. That will be (x, y, z) = (8, -2, -10).
Then our parametric equations can be written as
- x = 8 +12t
- y = -2 -2t
- z = -10 -15t
