Answer:

Step-by-step explanation:

depending on the space you're considering, it would be SOMETIMES true. But usually, the 2 lines would be parralel.

What i'm saying is, that in an euclidian space, the 2 lines would be parallel. In another kind of space, the two lines could be anything...

for example: look at how longitude and lattitude are represented on a globe : they are "lines"... 2 sets of perpendicular lines...

Now look at what happens in the poles : all lines intersect! (therefore, they're not parallel, and not necessarily perpendicular either)

In a woodworking class, you need to make five triangles out of plywood. Each triangle has a height of 6 inches and a base of 14

skelet666 [1.2K]

Answer:

210 in²

Step-by-step explanation:

Use the formula for area:

A = 1/2bh

Each triangle will have the area of:

A = 1/2*6*14 = 42 in²

Total amount of plywood will be:

42*5 = 210 in²

Write the equations for all vertical horizontal asymptotes. Vertical asymptote(s):Horizontal asymptote(s):Find all x-intercepts

NISA [10]

We have the next graph

And we must find:

1. Vertical asymptote(s):

We can see that there is a vertical asymptote when x = 2.

So, the vertical asymptote is

$x=2$

2. Horizontal asymptote(s):

We can see that there is a horizontal asymptote y = -1

So, the horizontal aymptote is

$y=-1$

3. x-intercept(s) and y-intercept(s):

We can see the graph intercepts the x-axis when x = -6

So, the x-intercept is (-6, 0)

We can see the graph intercepts the y-axis when y = 3

So, the y-intercept is (0, 3)

4. Domain nd Range:

Domain: The domain is the set of numbers that we can take in x-axis for the function.

Since we have a vertical asymptote that is x = 2 and we don´t have any more vertical asymptote the domain will be all real numbers except the value of the asymptote. So, the domain is

$\text{domain}\colon(-\infty,2)\cup(2,\infty)$

Range: The range is the set of numbers that the function takes in the y-axis.

Since we have only one horizontal asymptote the range will be all reals numbers except the value of the horizontal asymptote. So, the range is

$\text{range}\colon(-\infty,-1)\cup(-1,\infty)$

Wich is a factor of x^2+ 5x-24?

Nimfa-mama [501]

Answer:

(x−3)(x+8)

Step-by-step explanation:

Let's factor x2+5x−24

x2+5x−24

The middle number is 5 and the last number is -24.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get 5

Multiply together to get -24

Can you think of the two numbers?

Try -3 and 8:

-3+8 = 5

-3*8 = -24

Fill in the blanks in

(x+_)(x+_)

with -3 and 8 to get...

(x-3)(x+8)

Answer:

(x−3)(x+8)

Hope this helps.
