Find the product (2/9) x (9/5)

nevsk [136]

We can set it up like this:
$\frac{2}{9}\cdot \frac{9}{5}$
Multiply straight...
$=\frac{2\cdot \:9}{9\cdot \:5}$
Simplify...
$=\frac{2}{5}$
That's our answer, we can also convert it to decimal.

Answer in fraction form: $=\frac{2}{5}$
Answer in decimal form: $0.4$

Find the vector and parametric equations for the line through the point P(0, 0, 5) and orthogonal to the plane −1x+3y−3z=1. Vect

yulyashka [42]

Answer:

Note that orthogonal to the plane means perpendicular to the plane.

Step-by-step explanation:

-1x+3y-3z=1 can also be written as -1x+3y-3z=0

The direction vector of the plane -1x+3y-3z-1=0 is (-1,3,-3).

Let us find a point on this line for which the vector from this point to (0,0,5) is perpendicular to the given line. The point is x-0,y-0 and z-0 respectively

Therefore, the vector equation is given as:

-1(x-0) + 3(y-0) + -3(z-5) = 0

-x + 3y + (-3z+15) = 0

-x + 3y -3z + 15 = 0

Multiply through by - to get a positive x coordinate to give

x - 3y + 3z - 15 = 0

A wheelchair ramp is 16 feet Long. The ramp sits up on a 2 foot platform. How far is it from the end of the ramp to the bottom o

il63 [147K]

Answer:

√254 feet

Step-by-step explanation:

This is basically a triangle, with a height of 2, and hypotenuse of 16.

Using the Pythagorean theorem (a^2+b^2=h^2) we can find the other side.

2^2+b^2=16^2

4+b^2=256

b^2=254

b=√254
