Juan roller skates at the constant speed of 8 miles per hour. How far can he travel in 2.4 hours.

lara [203]

Answer: Juan can travel 19 miles in 2.4 hours at a speed of 8 miles per hour

Step-by-step explanation:

Juan roller skates at the constant speed of 8 miles per hour. Distance travelled is expressed as

Distance = speed × time

Therefore, the distance that Juan can travel in 2.4 hours is

Distance = 2.4 × 8 = 19.2 miles

Approximating to the nearest whole number, it becomes 19 miles

Find a vector function that represents the curve of intersection of the paraboloid z=3x2+2y2 and the cylinder y=6x2. Use the var

Cerrena [4.2K]

Answer:

$\vec{r(t)}=t\hat{i}+6t^2\hat{j}+(3t^2+72t^4)\hat{k} \text{ For }t \in (-\infty, \infty)$

Step-by-step explanation:

First plug the equation of y into the equation of z, so that we get their intersection:

We plug

$y=6x^2$

Into: $z=3x^2+2y^2$

So, we get:

$z=3x^2+2(6x^2)^2\\z=3x^2+2(36x^4)\\z=3x^2+72x^4$

Then we set

$x=t$

And plug that in the equation $y=6x^2$ and the one we just got for z.

So that we get:

$y=6t^2, z=3t^2+72t^4$

Therefore, the vector function that represents the curve of intersection is:

$\vec{r(t)}=t\hat{i}+6t^2\hat{j}+(3t^2+72t^4)\hat{k} \text{ For }t \in (-\infty, \infty)$

127.17 because 9x9=81 and 81x3.14=254.34 then divide by 2 and it’s equal 127.17
