(100*2)-30 
100 is multiplied by two to get 200 and then you subtract 30 to get 170 because they withdrew money so they took away money.

g Let P be the plane that goes through the points A(1, 3, 2), B(2, 3, 0), and C(0, 5, 3). Let ` be the line through the point Q(
Sedbober [7]

Answer:

  (x, y, z) = (1, 1/3, 3 1/3)

Step-by-step explanation:

The normal to plane ABC can be found as the cross product ...

  AB×BC = (1, 0, 2)×(2, -2, -3) = (4, 1, 2)

Then the equation of the plane is ...

  4x +y +2z = 4·0 +5 +2·3 . . . . using point C to find the constant

  4x +y +2z = 11

__

The direction vector of the reference line is the vector of coefficients of t: (0, -1, 2). Then the line through point Q is ...

  (x, y, z) = (1, 2, 0) +t(0, -1, 2) = (1, 2-t, 2t)

__

The value of t that puts a point on this line in plane ABC can be found by substituting these values for x, y, and z in the plane's equation.

  4(1) +(2 -t) +2(2t) = 11

Solving for t gives ...

  t = 5/3

so the point of intersection of the plane and the line is

  (x, y, z) = (1, 2-t, 2t) = (1, 2-5/3, 2·5/3) = (1, 1/3, 3 1/3)

A toy airplane climbs 30 vertical feet while traveling 50 feet horizontally. A toy helicopter climbs 20 feet while traveling 40
maw [93]

Answer:

The Slop of airplane is greater than slop of helicopter

Step-by-step explanation:

Given as

Vertical height of toy airplane = 30 feet

The horizontal distance is 50 feet

Let, The slop of toy airplane is H

Now by Pythagoras  theorem

H ²  = P² + B²

Or, H² = 30² + 50² = 900 + 2500

Or, H² = 3400 feet

SO, Slop = H =√3400 = 58.30  feet

Again

Vertical height of toy helicopter = 20 feet

The horizontal distance is 40 feet

Let, The slop of toy helicopter is h  

Now by Pythagoras  theorem

H ²  = P² + B²

Or, h² = 20² + 40² = 400 + 1600

Or, h² = 2000 feet

SO, Slop = h =√2000 = 44.72  feet  

Since H> h

Hence The Slop of airplane is greater than slop of helicopter Answer
