How do you use the slope to prove lines are parallel or perpendicular

Mathematics
1 answer:
zaharov [31]3 years ago
3 0

In order to find if two lines are parallel or perpendicular or neither, following rules are used:

  1. If the slope of two lines is the same, the two lines will be parallel
  2. If the product of slopes of two lines is -1, the two lines will be perpendicular to each other.
  3. If none of the above two conditions is being satisfied, this mean lines are neither parallel nor perpendicular.

So the steps that must be followed are:

  • Find the slope of the given lines.
  • Use the values of the slope to check which of the above point is being satisfied and draw the conclusion accordingly.

Determine whether or not f is a conservative vector field. if it is, find a function f such that f = ∇f. (if the vector field is
sineoko [7]
\mathbf f(x,y)=(ye^x+\sin y)\,\mathbf i+(e^x+x\cos y)\,\mathbf j is continuous, so \mathbf f(x,y) is indeed conservative. So we know there is some scalar function f(x,y) such that \nabla f(x,y)=\mathbf f(x,y).

\dfrac{\partial f}{\partial x}=ye^x+\sin y
\displaystyle\int\frac{\partial f}{\partial x}\,\mathrm dx=\int(ye^x+\sin y)\,\mathrm dx
f(x,y)=ye^x+x\sin y+g(y)

\dfrac{\partial f}{\partial y}=\dfrac{\partial(ye^x+x\sin y+g(y))}{\partial y}
e^x+x\cos y=e^x+x\cos y+g'(y)
0=g'(y)
\implies g(y)=C

So we have

f(x,y)=ye^x+x\sin y+C

True or Fase?<br> The slant height and the altitude (height) of a pyramid are the same thing.
sdas [7]

False, the slant height will be longer than the altitude because if you look at it like a right triangle, the slant height represents the hypotenuse.

If f (1)=10 and f (n)=f (n-1)-3 then find the value of f (4)
padilas [110]

Answer:

Given that the  height of the plant f(n), in cm, after n days:

To find n when f(n) = 11.04 cm

i.e. in 2.5 days

2) n cannot go up to infinity

If maximum growth is h, then domain is (0, )

3) Put n=0

y intercept = 10 cm.

4) This gives the initial height of the plant i.e. when n =0

5) Average rate of change = 10(1.04)^n ln 1.04

6) n =1,2,3,4,5

n 1      2               3        4                         5

f(n) 10.4 10.816 11.24864 11.6985856 12.16652902

(this is got by substituting n =1,2,3,4,5.

7) Avg rate of change in interval (a,b) = change in f(n)/change in n
