Find parametric equations for the tangent line to the curve with the given parametric equations at the specified point. x = t, y
DochEvi [55]

Answer:

Step-by-step explanation:

At the point (0, 1,0) t = 0

Find the tangent vector:

\frac{dx}{dt}= 1

\frac{dy}{dt}= -4e^{-4t}

\frac{dz}{dt}=5-5t^4

The tangent vector for all points \vec v(t) is

\vec v(t) = \hat {i}-4e^{-4t}\hat{j}+(5-5t^4)\hat{k}

\rightarrow \vec v (0)= \hat{i}-4\hat{j}

The vector equation of the tangent line is

(x,y,z) = (0,1,0)+s(\hat{i}-4\hat{j})

The parametric equation for this line are

x= s

y=1-4s

z=0

SIX LESS THAN TWICE A NUMBER, X, IS 38 WHAT IS THE VALUE OF X
stealth61 [152]

Answer:

17

Step-by-step explanation:

first write the equation:

twice a number x is 2x

six less is -6

so equation is 2x - 6 = 38

solve for x:

2x = 34

x = 17

Oki I have a few but I’m giving a lot of points I just didn’t feel like doing them separate.
Ghella [55]
Given two angles of a triangle, we can find the third one by subtracting what we have from 180:
180-63.2-75.9=40.9°.  This means C is correct.
This also means that B is correct; if a triangle is equilateral, all angles must be congruent as well, which these are not.

Cross multiplying the proportion we have:
x*1 = 3(y-3)
1x = 3y - 9
Solving for y, we first cancel the 9 by adding:
1x+9 = 3y
Now we cancel the 3 by dividing:
1x/3 + 9/3 = 3y/3
1/3x + 3 = y
In this format, we can see that the slope (m) is 1/3 and the y-intercept (b) is 3.

Going by the directions for the points P, Q, R, and S, PQ would be parallel to SR and PS would be parallel to QR.  These sides are not parallel to any other sides of this figure.

For the last problem, the vertices given do not form a parallelogram.  There is only 1 pair of parallel sides using these points.
