Answer:
The general solution is
Step-by-step explanation:
Given differential equation is
y''-4y'+4y=0
and
To find the we are applying the following formula,
The general form of equation is
y''+P(x)y'+Q(x)y=0
Comparing the general form of the differential equation to the given differential equation,
So, P(x)= - 4
The general solution is
Answer:
the P value is 45.22%
Step-by-step explanation:
The computation of the P value is as follows;
Given that
standard deviation = 14.9
mean = 675
Reduction in diameter= 673.2
Based on the above information,
We have to applied the following formula i.e.
Now the P value for -0.1208 is 0.4522 i.e. 45.22%
Hence, the P value is 45.22%
The same is to be considered
Answer:
-35,35,0
Step-by-step explanation:
Let's organise our information :
Now let's add them together :
- x+xy²+x-xy²=250y-240y
- 2x=10y
- x=5y ⇒ y= x/5
Let's replace y by x/5 in the first equation :
- x+x*(x/5)²=250*(x/5)
- x+ (x∧3)/25 = 50x
- 49x-(x∧3)/25=0
- x(49-(x²/25))=0
- x=0 or 49-(x²/25)=0
- x=0 or 49= x²/25
- x=0 or x²=1225
- x=0 or x= or x= -
- x=0 or x=35 or x= -35
so x=[0,35,(-35)]
1) √72z² = 6z √2 B.
2 * 6 * 6 = 72
2) C. √6
3 * 3 √6 - 4 * 2 √6 = 9√6 - 8√6 = √6
