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:

C. $19.65

Step-by-step explanation:

You have to find 20% of $98.25

This is equal to,

20% * $98.25                Because of usually means multiplication

= .20 * 98.25                 Because .20 = 20%

= 19.65!

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]

The answer is r={-8,1/4}

X: -4. Y: -3

Step-by-step explanation:

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.

The "open circle" represents less than or greater than, and the "closed circle" represents greater than or equal to or less than or equal to.

Hope it helps! Have a great day! :) let me know if it helped

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:

He bought 3 jumbo packs and 4 hobby packs.

Step-by-step explanation:

Ethan bought 4 number of hobby packs and 3 number of jumbo packs.

Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.

Linear equations may include one or more variables.

Let x be the number of hobby pack that Ethan buy and y be the number of jumbo packs that Ethan buy.

Ethan bought 7 packs for a total of 141 cards.

We got two linear equations here :

x + y = 7

9x + 35y = 141

Multiplying the first equation throughout by 9,

9x + 9y = 63

Subtracting the resulting equation we get from the second equation,

(9x + 35y) - (9x + 9y) = 141 - 63

35y - 9y = 78

26y = 78

y = 3

x = 7 - y = 4

Hence Ethan bought 4 hobby packs and 3 jumbo packs.
