Oslo is colder than Copenhagen by 7 degrees. When finding the colder temperature below 0, the larger number with a minus sign in front is the colder temperature. For example -9degrees is colder than -2 degrees.

Find a vector parametrization for the line with the given description. Perpendicular to the yz-plane, passes through (0, 0, 8)

Brilliant_brown [7]

Answer:

$\left\{\begin{array}{l}x=t\\ \\y=0\\ \\z=8\end{array}\right.$

$\overrightarrow{(t,0,8)}$

Step-by-step explanation:

yz-plane has the equation $x=a,$ where $a$ is a real constant. The normal vector of this plane (vector perpendicular to the plane) is

$\overrightarrow {n}=(1,0,0)$

If the line is perpendicular to this plane, then it is parallel to the normal vector, so the equation of this line is

$\dfrac{x-x_0}{1}=\dfrac{y-y_0}{0}=\dfrac{z-z_0}{0},$

where $(x_0,y_0,z_0)$ are coordinates of the point the line is passing through.

In your case, the line is passing through the point (0,0,8), so the canonical equation of the line is

$\dfrac{x-0}{1}=\dfrac{y-0}{0}=\dfrac{z-8}{0}$

Write a vector parametrization for this line

$\left\{\begin{array}{l}\dfrac{x-0}{1}=t\\ \\\dfrac{y-0}{0}=t\\ \\\dfrac{z-8}{0}=t\end{array}\right.\Rightarrow \left\{\begin{array}{l}x=t\\ \\y=0\\ \\z=8\end{array}\right.$

You are building a skateboard ramp from a piece of wood that is 3.1 meters long. You want the ramp to make and angle of 25 with

andrew11 [14]

Answer:

30 degrees.

Step-by-step explanation:

The ladder that extends from the floor to the storeroom makes a right triangle. The ramp is the hypotenuse measuring 10 m and the elevation of the storeroom is the opposite side. The angle of elevation is the arcsin of the quotient of the 5/10. Thus, the answer is 30 degrees.

Michael works 30 hours per week and makes $15.00 per hour. How much does he make in a 4-week month?

Wewaii [24]

Answer:

$1,800

Step-by-step explanation:

If Michael works 30 hours a week for $15 an hour we can use the equation:

15 x 30 = 450.

Now just multiply the given answer by 4 and you're left with:

450 x 4 = 1800.
