Rewrite the following equation in slope-intercept form. 6x − 14y = -3 Write your answer using integers, proper fractions, and im
Alex17521 [72]
Answer:
y = (3/7) x + (3/14)

Explanation:
The slope-intercept form has the following formula:
y = mx + c
where:
m is the slope
c is the y-intercept

The given is:
6x - 14y = -3

To get in the slope-intercept form, we need to isolate the y as follows:
6x - 14y = -3
14y = 6x + 3
y = (6/14)x + (3/14)
y = (3/7) x + (3/14)

Hope this helps :)

Find the unit tangent vector T(t) to the curve r(t) = [sin(t), 1 + t, cos(t)] when t = 0.
ss7ja [257]

Compute the derivative of \mathbf r(t) at t=0 - this will be the tangent vector - then normalize it by dividing it by its magnitude to get the unit tangent vector \mathbf T(t).

\mathbf r(t) = \langle \sin(t), 1+t, \cos(t) \rangle \implies \dfrac{d\mathbf r}{dt} = \langle \cos(t), 1, -\sin(t) \rangle \implies \dfrac{d\mathbf r}{dt}(0) = \langle 1, 1, 0 \rangle

\|\langle1,1,0\rangle\| = \sqrt{1^2+1^2+0^2} = \sqrt2

\implies\mathbf T(0) = \dfrac{\langle1,1,0\rangle}{\sqrt2} = \boxed{\left\langle \dfrac1{\sqrt2}, \dfrac1{\sqrt2}, 0\right\rangle}

Plzzzzzx anyone help me
Yuki888 [10]

First look at the points and find their x and y values. So we have:

(-3,3), (0,0), (3,3)

Next separate the x values and the y values

x values: -3, 0, 3

y values: 3, 0, 3

The x values are your domain and the y values are are range

So the answer is b
