Alex777 [14]

Answer: Multiplicative rate of change in housing costs, for summer term t years since Chinedu applied to his college.

Step-by-step explanation:

Given: 1.5\times1.09^t models the housing costs, in thousands of dollars, for summer term t years since Chinedu applied to his college.

Since, the above expression is an exponential function. [ t is the exponent ]

The standard exponential function is given by :-

y=Ab^x, A is the initial amount , b is the multiplicative rate of change with respect to time period x.

as compare to the given expression, we get b= 1.09, which is the multiplicative rate of change in the housing costs, for summer term t years since Chinedu applied to his college.

Nagaraj has a​ party-length sandwich that is 45 inches long and is to be cut into three pieces. The middle piece will be 3 inche
Sergio039 [100]

Answer:

The length of the shortest piece is  11 inches. The length of the medium piece is   14 inches. The length of the longest piece is  20 inches.

Step-by-step explanation:

Ok, so we have a long sandwich of 45 inches that will be divided in 3, giving us the following formula (x = shortest, y = medium, z=longest):

x + y + z = 45

Then we have middle piece (y) is 3 inches longer than the smallest (x):

y = x + 3

And the shortest  piece (x) is 9 inches shorter than  the longest (z):

x = z - 9 or z = x + 9

Let's place the found values of y and z in the first equation:

x + y + z = 45

x + (x + 3) + (x + 9) = 45

3x + 12 = 45

3x = 33

x = 11

So, x = 11, y = 14 and z = 20.  (11 + 14 + 20 = 45).

List all possible permutations
lesantik [10]

1. 1, 2, 3 has 3! = 6 possible permutations:

1 2 3 // 1 3 2 // 2 1 3 // 2 3 1 // 3 1 2 // 3 2 1

2. T, V, W taken 2 at a time has \dfrac{3!}{(3-2)!}=6 possible permutations:

T V // T W // V T // V W // W T // W V

3. I'll replace these symbols with f, s, h, and t (face, sun, heart, triangle). This sequence has \dfrac{4!}{(4-2)!}=12 possible permutations:

f s // f h // f t // s f // s h // s t // h f // h s // h t // t f // t s // t h

4. This has 4! = 24 possible permutations.

A B C D // A B D C // A C B D // A C D B // A D B C // A D C B //

B A C D // B A D C // B C A D // B C D A // B D A C // B D C A //

C A B D // C A D B // C B A D // C B D A // C D A B // C D B A //

D A B C // D A C B // D B A C // D B C A // D C A B // D C B A
