Which option below best describes why the domain of g(x) = 5–x is all real numbers but the range of g is not all real numbers?

1 answer:

4 0

The reason why the domain of g(x)=5⁻ˣ has a domain of all real numbers while the range is not is because, every real number value of x makes perfect sense as an exponent, that means there no restrictions because there are divisions by zero or the square root of the negative number.
The reason why the range is not all real number is because of the negative exponent. This will limit the range to positive real numbers only.

Given the domain (-2,2,4) what is the range for the relation 3x-y=3

Bumek [7]

Answer:

Given the domain, the range for 3x-y = 3 is {-9, 6, 9}

Step-by-step explanation:

First you have to put the relation in terms of y ⇒ 3x - y = 3⇒ 3x -3 = y

⇒ y = 3x - 3.

Then you replace the values indicated by the domain to find their "y" values (the ones that constitute the range).

f(-2) = -9

f(2) = 6

f(4) = 9.

Finally, the range for the given domain is {-9, 6, 9}

Question 10 Multiple Choice Worth 1 points)

Elis [28]

Answer:

Length = 8 feet

Step-by-step explanation:

Perimeter = 2 x ( length + width )

20 = 2 x (length + 2)

10 = Length + 2

10 - 2 = Length

Therefore, Length = 8 feet

The petronas towers in Kuala Lumpur, Malaysia, are 452 meters tall. A woman who is 1.75 meters tall stands 120 meters from the b

bazaltina [42]

Answer:

$75.1^{\circ}$

Step-by-step explanation:

In this problem, we have:

H = 452 m is the height of the Petronas tower

h = 1.75 m is the height of the woman

d = 120 m is the distance between the woman and the base of the tower

First of all, we notice that we want to find the angle of elevation between the woman's hat the top of the tower; this means that we have consider the difference between the height of the tower and the height of the woman, so

$H' = H-h = 452-1.75=450.25 m$

Now we notice that $d$ and $H'$ are the two sides of a right triangle, in which the angle of elevation is $\theta$ . Therefore, we can write the following relationship:
