Two planes intersect in exactly one point

Mathematics
1 answer:
adell [148]3 years ago
7 0

Answer:

If two planes intersect, then their intersection is a line. A line contains at least two points. If two lines intersect, then exactly one plane contains both lines. If a point lies outside a line, then exactly one plane contains both the line and the point.

The scale factor of the blueprint of a gymnasium to the actual gymnasium is 1in/15ft . The area of the floor on the blueprint is
miskamm [114]
B) 25, 650 ft^2
If the ratio is 1:15, then the measurements of each side of the actual gym are 15 times greater than the scale's. So the areas would have a ratio of 1:225. 114 times 225 is equal to 25, 650

Find all solutions to the equation.
anyanavicka [17]

Answer:

x=n\pi or x= \frac{(2n\pm1)\pi}{2}, where n\ge0

Step-by-step explanation:

The given trigonometric equation is:

(\sin x)(\cos x)=0

By the zero product principle;

Either \sin x=0 or \cos x=0

When  \sin x=0,  then x=n\pi

When \cos x=0, then x=2n\pi \pm \cos^{-1}(0)

This implies that: x=2n\pi \pm \frac{\pi}{2}

Therefore the general solution is  x=n\pi or x= \frac{(2n\pm1)\pi}{2}, where n\ge0

A parabola has an x-intercept of -1, a y-intercept of -3, and a minimum of -4 at x = 1.
torisob [31]

Answer:

The graph in the attached figure

Step-by-step explanation:

we know that

The equation of a vertical parabola in vertex form is equal to

y=a(x-h)^{2}+k

where

a is a coefficient

(h,k) is the vertex

In this problem we have

(h,k)=(1,-4)

substitute

y=a(x-1)^{2}-4

we have

An x-intercept of (-1,0)

substitute and solve for a

0=a(-1-1)^{2}-4

0=4a-4

4a=4

a=1

The equation is

y=(x-1)^{2}-4

<u><em>Verify the y-intercept</em></u>

For x=0

y=(0-1)^{2}-4

y=-3

The y-intercept is the point (0,-3) -----> is correct

using a graphing tool

see the attached figure
