Answer:

The slope is 2.

Step-by-step explanation:

You have your graph marked and ready to find the slope.

slope = rise/run

rise = vertical distance (up or down)

run = horizontal distance (left or right)

Start at the lower point you have marked in the graph.

That point is (-2, -7).

We need to go to the other point you have marked on the line, but we can only move vertically (up or down) and horizontally (left or right).

We start at point (-2, -7) and we go 2 units up along the segment you drew.

2 units up is a rise of +2.

Now we go 1 unit right along the segment you drew.

1 unit right is a run of +1.

slope = rise/run = 2/1 = 2

Answer: The slope is 2.

You ride your bike at an average of 12 miles per hour on the way to school, and at an average of 15 miles per hour on the way ho

-Dominant- [34]

Answer:

2.44 miles

Step-by-step explanation:

Give the following :

Average miles to school = 12 miles per hour

Average Miles from school = 15 miles per hour

Total ride time : ( time to school + time from school) = 22 minutes = (22/60) = 0.3667

Recall:

Speed = distance / Time

Time = distance / speed

Let distance = d

For the scenario described :

d/12 + d/15 = 0.3667

(5d + 4d) / 60 = 0.3667

5d + 4d = 22

9d = 22

d = 22/9

d = 2.44 miles

Which is a greater y-intercept (0,-1) or (0,-2)

kolezko [41]

Answer:

(0,-1)

Step-by-step explanation:

Find the directional derivative of f(x,y,z)=2z2x+y3f(x,y,z)=2z2x+y3 at the point (−1,4,3)(−1,4,3) in the direction of the vector

Feliz [49]

$f(x,y,z)=2z^2x+y^3$

$f$ has gradient

$\nabla f(x,y,z)=2z^2\,\vec\imath+3y^2\,\vec\jmath+4xz\,\vec k$

which at the point (-1, 4, 3) has a value of

$\nabla f(-1,4,3)=18\,\vec\imath+48\,\vec\jmath-12\,\vec k$

I'm not sure what the given direction vector is supposed to be, but my best guess is that it's intended to say $\vec u=15\,\vec\imath+25\,\vec\jmath$ , in which case we have

$\|\vec u\|=\sqrt{15^2+25^2}=5\sqrt{34}$

Then the derivative of $f$ at (-1, 4, 3) in the direction of $\vec u$ is

$D_{\vec u}f(-1,4,3)=\nabla f(-1,4,3)\cdot\dfrac{\vec u}{\|\vec u\|}=\boxed{\dfrac{294}{\sqrt{34}}}$
