What is the answer to this question?

Answer:

It would be answers A and C

Step-by-step explanation:

Notice both end in negative 2, matching your range, so you can't get that correct using either B or D

The functions having domain (-∞,∞) and range (-2,∞) are f(x)=[tex]0.25^{x}-2[/tex] and f(x)=[tex]3^{x}-2[/tex].

A function is relationship between two or more variables expressed in equal to form .In a function each value of x must have a corresponding y value. The value of x is known as domain of the function and the value of y is known as range of function.

We have been given four functions and we have to find the functions having domain (-∞,∞) and range (-2,∞).

Taking f(x)=[tex]0.25^{x}-2[/tex]

f(0)=1-2

=-1

f(1)=0.25-2

=-1.75

f(2)=0.50-2

=-1.50

f(-2)=1/0.50-2

=1-1/0.50

=0

So this function has domain (-∞,∞) and range (-2,∞) because the value of function increases from -2 as the value of x increases.

Taking f(x)=[tex]0.25^{x}+2[/tex]

Because the above function is opposite of the first function so it behaves opposite as the function.

Taking f(x)=[tex]3^{x} -2[/tex]

f(0)=1-2

=-1

f(1)=3-2

=1

f(-2)=1/9-2

=(1-18)/9

=-17/9

=-1.8

This function also has domain (-∞,∞) and range  (-2,∞) because the value of increases from -2 as the value of x increases.

Next function is opposite from the third function so it behaves opposite to third function

Hence the functions having domain (-∞,∞) and range (-2,∞) are f(x)=[tex]0.25^{x}-2[/tex] and f(x)=[tex]3^{x}-2[/tex].

Answer:

(a) 36 routes

(b) 6 routes

Step-by-step explanation:

Given

[tex]North\ Point \to Boulder\ Creek = 3[/tex]

[tex]Boulder\ Creek \to Beaver\ Dam = 4[/tex]

[tex]Beaver\ Dam \to Star\ Lake= 4[/tex]

[tex]Boulder\ Creek\to Star\ Lake= 2[/tex]

Solving (a): From [tex]North\ Point[/tex] to [tex]Star\ Lake[/tex] through [tex]Beaver\ Dam[/tex]

To do this, we consider the following routes;

[tex]North\ Point \to Boulder\ Creek \to Beaver\ Dam \to Star\ Lake[/tex]

Taking a pair of routes, we have:

[tex]North\ Point \to Boulder\ Creek = 3[/tex]

[tex]Boulder\ Creek \to Beaver\ Dam = 4[/tex]

[tex]Beaver\ Dam \to Star\ Lake= 4[/tex]

By multiplication route, we have:

[tex]Routes = 3 * 4 * 3[/tex]

[tex]Routes = 36[/tex]

(b) From [tex]North\ Point[/tex] to [tex]Star\ Lake[/tex] bypass [tex]Beaver\ Dam[/tex]?

To do this, we consider the following routes

[tex]North\ Point \to Boulder\ Creek \to Star\ Lake[/tex]

Taking a pair of routes, we have:

[tex]North\ Point \to Boulder\ Creek = 3[/tex]

[tex]Boulder\ Creek\to Star\ Lake= 2[/tex]

By multiplication rule, we have:

[tex]Routes = 3 * 2[/tex]

[tex]Routes = 6[/tex]

Step-by-step explanation:

Answer:

m<1 = 125°

m<2 = 55°

Step-by-step explanation:

Okay, so we're dealing with alternate interior angles and all that sorta stuff, so I'll try to explain it best I can, if I'm too confusing let me know, let's go:

So the angle labeled 125° and angle 1 are alternate interior angles, so they're equal (yes, we're ignoring the fact that that might not me right because the other line isn't straight, I don't have another solution okay) anyways, so that means that:

1 = 125°

Now we know what 1 and 2 are on the same plane or axis or something like that, so basically, 1 and 2 HAVE TO add up to 180°, so that means that:

125 + x = 180

And now we just have to do the inverse operations thing:

180 - 125 = 55

So, m<1 = 125° and m<2 = 55°

tell me if this is wrong so I can fix it

hope this helps:)

Answer:

x = 12

Step-by-step explanation:

<CED = 180 - (9x-8)

= 180 - 9x +8

= 188 - 9x

Angle sum of triangle is 180

.'. (5x-10) + (50) + (180 - 9x +8) = 180

5x -10 + 50 + 188 -9x = 180

-4x = 180 + 10 - 50 - 188

-4x = -48

4x = 48

x = 12

Answer:

Step-by-step explanation:

Terminal points of vector u has been given as (4, 0), (9, 4).

Therefore, vector u can be represented by,

[tex]\vec{u}=\vec{u_2}-\vec{u_1}[/tex]

[tex]\vec{u}=(9i+4j)-(4i)[/tex]

[tex]\vec{u}=5i+4j[/tex]

And the magnitude of the vector u will be,

|| u || = [tex]\sqrt{5^2+4^2}[/tex]

       = [tex]\sqrt{41}[/tex]

Slope of vector passing through [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is defined by the expression,

Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Therefore, slope of vector u will be,

Slope = [tex]\frac{4-0}{9-4}[/tex]

          = [tex]\frac{4}{5}[/tex]

Similarly, terminal points of vector v are (-7, 1) and (3, 9).

So the vector v will be,

[tex]\vec{v}=(3i+9j)-(-7i+1j)[/tex]

[tex]\vec{v}=(3i+7i)+(9j-1j)[/tex]

[tex]\vec{v}=10i+8j[/tex]

Therefore, magnitude of vector v will be,

|| v || = [tex]\sqrt{10^2+8^2}[/tex]

        = [tex]\sqrt{164}[/tex]

        = [tex]2\sqrt{41}[/tex]

Slope of vector v = [tex]\frac{9-1}{3+7}[/tex]

                             = [tex]\frac{8}{10}[/tex]

                             = [tex]\frac{4}{5}[/tex]

The blue dot is at -15 because the line is counting by fives rather than by ones, twos, threes, etc. So, when you count from the left from 0, it goes by -5, -10, -15 which is where the blue dot is. Hope this helps :)

The graph that represents the following piecewise defined function is graph D (Image attached).

A piecewise function is known to be a type of function that is known to be formed or created from scratch (pieces) of different functions over different intervals.

An example, a person can make a piecewise function f(x) where f(x) = -9 when -8 < x ≤ -4, f(x) = 5 when -4 < x ≤ -1, and f(x) = -6 when -1 <x ≤ 9. Looking at the graph attached, you can see that it tells us more about  piecewise defined function.
