The price of a computer component is decreasing at a rate of 13​% per year. State whether this decrease is linear or exponential
nika2105 [10]

Answer:

$59.27

Step-by-step explanation:

It is exponential decrease.

After each year goes by its worth 100 - 0.13 = 0.87 of the previous value.

The equation of decrease  is V = 90(0.87)^t   where t = the number of years.

So after 3 years it is worth  90(0.87)^3

= $59.27.

I need help. Thank you.

Answer:

v=b (the answer is option b.)

Step-by-step explanation:

3b=6v−3b

Rewrite the equation as 6v−3b=3b.

6v−3b=3b

Move all terms not containing v to the right side of the equation.

Add 3b to both sides of the equation.

6v=3b+3b

Add 3b and 3b.

6v=6b

Divide each term by 6 and simplify.

Divide each term in 6v=6b by 6.

6v/6=6b/6

Cancel the common factor of 6.

v=6b/6

Cancel the common factor of 6.

v=b

Hope this helps! Plz mark as brainliest! :)

Given the function f(x)=4(2)2, Section A is from x=1 to x=2 and section B is from x=3 to x=4. Part A: find the average rate of c
Pepsi [2]

Answer:

I found thois from someone else asking this queetion so gope it helps.

Step-by-step explanation:

I'm sure you want your functions to appear as perfectly formed as possible so that others can help you.  f(x) = 4(2)x should be written with the " ^ " sign to denote exponentation:  f(x) = 4(2)^x

                                                                                     f(b) - f(a)

The formula for "average rate of change" is a.r.c. = --------------

                                                                                          b - a

                                   change in function value

This is equivalent to  ---------------------------------------

                                           change in x value

For Section A:  x changes from 1 to 2 and the function changes from 4(2)^1 to  4(2)^2:  8 to 16.  Thus, "change in function value" is 8 for a 1-unit change in x from 1 to 2.  Thus, in this Section, the a.r.c. is:

                8

              ------ = 8 units    (Section A)

                 1

Section B:  x changes from 3 to 4, a net change of 1 unit:  f(x) changes from

4(2)^3 to 4(2)^4, or 32 to 256, a net change of 224 units.  Thus, the a.r.c. is

       224 units

     ----------------- = 224 units (Section B)

           1 unit

The a.r.c for Section B is 28 times greater than the a.r.c. for Section A.

This change in outcome is so great because the function f(x) is an exponential function; as x increases in unit steps, the function increases much faster (we say "exponentially").
