3x^2y+5xy^2 is Cubic polynomial or binomial.
Answer:
the total charge is
Step-by-step explanation:
Since x is measured from the center, that means that x=0 is the center so the edges of the rod correspond to x=-6 and x=6. that meas that the total charge can be calculated as
separating the integral from -6 to 0 and from 0 to 6, taking into account that |x|=-x for x<0 and |x|=x for x >=0, we get
using the substitution x=-u in the first integral we get
which is the same as the first integral. Thus, the total charge is given by
integrating we get
Y=mx+c
y=7/18x+c
now we will find the value of c
20=7/18*4+c
20=28/18+c
20=14/9+c
20-14/9=c
180-14/9=c
18.4=c
so the equation is y=7/18x+18.4
Answer:6 1/2
Step-by-step explanation:1/2+3 1/2+2 1/2
Add all the halves (1/2)
1/2+1/2+1/2=1 1/2
Then add the 3 and 2 in front of the fraction.
3+2=5
So, 1 1/2+5=6 1/2
The equation is 138=300-3x
now solve by first subtracting 300 from each side: -162=-3x
divide each side by -3: x=54
