Find an equation of the plane with x-intercept a, y-intercept b, and z-intercept c. What is the distance between the origin and
Elenna [48]

Answer:

The equation is:

(1/a)x + (1/b)y + (1/c)z = 1

Step-by-step explanation:

The direction vector between the points (a, 0, 0) and (0, b, 0) is given as:

<0 - a, b - 0, 0 - 0>

<-a, b, 0> .....................(1)

The direction vector between (0, 0, c) and (0, b, 0) is given as:

<0 - 0, b - 0, 0 - c>

= <0, b, -c> .....................(2)

To obtain the direction vector that is normal to the surface of the plane, we take the cross product of (1) and (2).

Doing this, we have:

<-a, b, 0> × <0, b, -c> = <-bc, -ac, -ab>

To find the scalar equation of the plane we can use any of the points that we know. Using (0, b, 0), we have:

(-bc)x + (-ac)y + (-ab)z = (-bc)0 + (-ac)b + (-ab)0

(bc)x + (ac)y + (ab)z = (ac)b

Dividing both sides by abc, we have:

(1/a)x + (1/b)y + (1/c)z = 1

Harold paid 5% in sales tax on his new "smart fabric" warm-ups.
natita [175]

Answer:

The pre-tax price of "smart fabric" warm-ups is $745 .

Step-by-step explanation:

Let us assume that the pre-tax price of the "smart fabric" warm-ups be x .

As given

arold paid 5% in sales tax on his new "smart fabric" warm-ups.  

if harnold paid 37.25 in sales tax on the warm ups .

5% is written in the decimal form .

=\frac{5}{100}

= 0.05

Equations becomes

0.05 × x = 37.25

0.05x = 37.25

x = \frac{37.25}{0.05}

x = $745

Therefore the pre-tax price of "smart fabric" warm-ups is $745 .
