Answer:

The wheels have to rotate 500 times

Step-by-step explanation:

The wheel is 1 meter in diameter so we need to find the circumference.

C = 2 $\pi$ r

C = 2 $\pi$ 1

C= 2 $\pi$

2meters = .002kilometers

1000meters = 1kilometer

1000/2 = 500

expeople1 [14]

Answer:

$14

Step-by-step explanation:

Oliver earnings per day = $4

Each day, his mom takes $2 and put it into a savings account for Oliver

His savings per day = $2

Oliver's total savings after 7 days = savings per day × 7 days

= $2 × 7

= $14

Oliver gets to keep a total of $14 after 7 days

Find the vector equation for the line of intersection of the planes 5x+3y−2z=−45x+3y−2z=−4 and 5x+5z=0

olga_2 [115]

$5x+5z=0\implies x+z=0\implies z=-x$

$5x+3y-2z=7x+3y-2x-2z=7x+3y-2=-4\implies7x+3y=-2$

Letting $x=t$ and $z=-t$ , we have

$7t+3y=-2\implies y=-\dfrac73t-\dfrac23$

so the intersection is given by

$\mathbf r(t)=\left(t,-\dfrac73t-\dfrac23,-t\right)$
