The required expression that gives the number of months t in terms of the price p is, t(p) =√1/2 (600-p).

The given function is p(t) = 600 − 2t².

We need to find the expression that gives the number of months t (passed since January 1) in terms of the price p.

Functions are the fundamental part of calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x. Mapping or transformation is used to denote a function in math. These functions are usually denoted by letters such as f, g, and h.

Here, the expression that gives p in terms of t is, p(t) = 600 − 2t²----(1)

Where p represents the price and t represents the number of months t (passed since January 1).

From equation (1),

p= 600 − 2t²

⇒2t²=600-p

⇒t²=1/2 (600-p)

⇒t=±√1/2 (600-p)

But, the number of months can not be negative, t=√1/2 (600-p).

Since in this expression t is in the term of p.

Hence, the required expression that gives the number of months t in terms of the price p is, t(p) =√1/2 (600-p).

Your question is incomplete, probably the complete question/missing part is:

Statistical models predict that the price (in dollars) of a 500 GB hard drive will change according to the function p(t) = 600 − 2t², where t is the month. Which expression gives the number of months t (passed since January 1) in terms of the price p?

Answer:

No

Step-by-step explanation:

The first and 2nd answer are different because in the first one the circle is open and in the 2nd one the circle is closed. When the circle is open it means that the number that the circle is on is not a part of the asnwer. This is represented by < or > signs. When the circle is closed it means the number is included in the answer. This is represented by the [tex]\leq or \geq[/tex] symbol.

Answer: Third option.

Step-by-step explanation:

We have the variables:

x =  number of roses that Sarah buys

y = number of carnations that Sarah buys.

Each rose costs $3, then the price for x roses is: x*$3.

Each carnation costs $1, then the price for y carnations is: y*$1.

The total price will be:

$3*x + $1*y

And she can spend no more than $75, then we have the inequality:

$3*x + $1*y ≤ $75

Writing this as a line, we have:

y ≤ 75 - 3*x

Then the graph of this will be:

A solid line with a negative slope and the shaded part will be below that line.

The value of y goes between 0 and 75.

The value x goes between 0 and the value of x such y = 0, this is:

y = 0 ≤ 75 - 3*x

 3*x ≤ 75

     x ≤ 75/3 = 25

Then the value of x goes between 0 and 25.

The correct option will be the third one.

The correct graph is option 3.

Given,

Sarah buys x no. of roses and y no. of carnations.

The cost of each roses be $3, so cost of x roses be 3 x .

And the cost of each carnations be $1, so cost of y carnations be y.

The total cost will be  [tex]3x + y.[/tex]

But as given in question she can spend no more than $75, so we have the inequality  [tex]3x + y \leq 75[/tex].

Writing the above equation as a line we have  [tex]y\leq 75-3x[/tex].

So graph of above line will be a solid line with a negative slope and the shaded part will be below that line so the value of y goes in between 0 and 75.

Now, value of x when y is o will be calculated from  [tex]y\leq 75-3x[/tex].

[tex]0\leq 75-3x[/tex]

[tex]3x\leq 75[/tex]

[tex]x\leq \frac{75}{3}[/tex]

[tex]x\leq 25[/tex]

Now we have values of x in between 0 and 25.

here we have y in between 0 and 75 with a negative slope and x in between 0 and 25. so the shaded part will be below that line goes in between 0 and 75 on y axis . option 3 has shaded part in between 0 and 75 on y axis  so the correct option is 3.

The statistic which is most appropriate in the given situation is Mode.

Mode is defined as the statistical method which gives the value of an entity that occurs the greatest number of times in a set of values of data. For example, if the marks of 5 students scored in a test are given as 35, 45, 35, 35, 50 then the mode of the given set of data is 35 as it occurs the maximum number of times. Here, the student is sure that the principal will call out the name of a certain number of tables very often. She keeps track of the tables over 21 days and as the table number was called out for the maximum number of times within 21 days the value of the table number will be given by the Mode of the data.

Thus, the most suitable method is Mode.

a. f(a) =5a+12

we have 1. a=6

Therefore, where ever we find a we'll substitute in 6

f(6) =5(6) +12

6f=30+12

6f=42

so therefore 1. a=6 will match c on the right

2. a=2

f(2) =5(2) +12

2f = 10+12

2f = 22

therefore 2. a=2 will match a on the right

3. a=4

f(4) =5(4) +12

4f=20+12

4f=32

therefore 3. a=4 will match d on the right

4. a=5

f(5) =5(5) +12

5f=25+12

5f=37

therefore 4. a=5 will match b on the right

Answer:

[tex]y = \frac{3}{2} x + 2[/tex]

Step-by-step explanation:

It gives us the slope in the question (3/2), so we can write an equation that looks like this:

[tex]y = \frac{3}{2} x + b[/tex]

To find the y-intercept we can plug the point (4,8) in the equation. Remember that 4 is x and 8 is y.

[tex]8 = \frac{3}{2} (4)+ b[/tex]

Now solve for b

[tex]8 = \frac{12}{2} + b\\8 = 6 + b\\2 = b[/tex]

Next, write the full equation using the slope and y-intercept:

[tex]y = \frac{3}{2} x + 2[/tex]
