Answer:

D. The range of the function is all real numbers greater than or equal to 0.

Step-by-step explanation:

The graph of the function $y=\sqrt{-x}$ is shown in attached diagram.

1. The domain of the function is the set of all possible values for input (for x). Hence, the domain of this function is

$x\in (-\infty,0]$

2. The range of the function is the set of all possible values for output (for y), so the range of this function is

$y\in [0,\infty)$

As you can see, only option D is true - The range of the function is all real numbers greater than or equal to 0.

Ella is a landscape photographer. One weekend at her art gallery she sells a total of 52 prints for a total of $2,975. How many

abruzzese [7]

Answer:

Ella sold the each print for the cost of $57.21.

Step-by-step explanation:

The total number of prints sold at gallery = 52

Total amount it is sold for = $2,975

Noe, If 52 prints are sold for $2,975.

⇒ $\textrm{Cost of 1 print} = \frac{\textrm{Total cost of 52 prints}}{\textrm{52}}$

$= \frac{2,975}{52} = 57.21$

or, Cost of 1 print = $57.21

So, Ella sold the each print for the cost of $57.21.

HELP PLEASE ITS DUE IN 10 MIN Use algebraic strategies to solve for x.

mr Goodwill [35]

Answer:

x = 4, x ≠ -1

Step-by-step explanation:

√3x + 4 = x

(√3x + 4)² = x² (Square both sides to get rid of the radical.)

3x + 4 = x²

0 = x² - 3x - 4 (Set everything to 0 by moving everything to one side.)

0 = (x - 4)(x + 1) (Factor.)

x = 4 x = -1

Now we need to check for extraneous solutions:

√3(4) + 4 = 4

√12 + 4 = 4

√16 = 4

4 = 4

√3(-1) + 4 = -1

√-3 +4 = -1

√1 = -1

1 ≠ -1

-1 is an extraneous solution.

A college professor reports that students who finish exams early tend to get better grades than students who hold on to exams un

s344n2d4d5 [400]

Answer:

The correlation between exam score and amount of time spent on the exam is an example of a <u>negative correlation</u>.

Step-by-step explanation:

Consider the provided statement.

College professor reports that students who finish exams early tend to get better grades than students who hold on to exams until the last possible moment.

That means the student who finish the exam early will get the highest marks. One who finish after the first student will get second highest mark and the one who finish in the end will get the least marks.

Now consider time as first variable and marks as second variable.

That means as the first variable increase the second variable decreases.

According to the definition of Negative correlation: It is a relationship between two variables in which one variable increases as the other decreases, and vice versa.

Hence, the correct answer is negative correlation.
