What are the possible values of x and y for two distinct points, (5, –2) and (x, y), to represent a function?

bonufazy [111]

The correct answer is:

Any real number for x except 5, and any real number for y.

Explanation:

A function is a relation in which each element of the domain, or x-value, is mapped to one element of the range, or y-value. This means that no x can be mapped to more than one y, so if we have the same number used twice for x, we do not have a function.

This means that 5 cannot be used for x in the other ordered pair.

Since there is no restriction on y in order to be a function, y can be any real number.

Jack had 4 hours of school. He spent 45 minutes in the library and 12 hour on a science lecture and had a lunch break of 25 minu

andre [41]

Answer:

$\dfrac{10}{4} \ hour$

Step-by-step explanation:

Given that :

Jack had 4 hours of school.

He spent 45 minutes in the library

1/2 hour on a science lecture and;

had a lunch break of 25 minutes

The objective is to determine how much time is left for the school to get over and we are to write the answer as a fraction.

In order to do that, we will have to convert the minutes into hours,

we all know that; 60 minutes = 1 hour.

Then,

45 minutes = (45/60)hour = 3/4 hour

25/60 minutes = 1/4 hour

Therefore, the amount of time left for the school to get over is:

= $4 - (\dfrac{3}{4}+\dfrac{1}{2}+ \dfrac{1}{4})$

= $\dfrac{16-(3+2+1)}{4}$

= $\dfrac{16-6}{4}$

= $\dfrac{10}{4} \ hour$

QuestionIn PQR, sin P = 1/3, sin R = 2/3,and p = 9. Find the side length r.

mamaluj [8]

Lets draw our triangle:

Lets use the "Law of Sines" to find our side r:

$\frac{p}{\sin P}=\frac{r}{\sin R}\rightarrow\frac{9}{\frac{1}{3}}=\frac{r}{\frac{2}{3}}\rightarrow9\times\frac{3}{1}\times\frac{2}{3}=r\rightarrow r=18$

So r=18
