An arithmetic sequence is represented by the recursive formula

a1=13
a^n=a^n−1 −7 .

What is the fifth term in the sequence?


a5=−8

a5=−15

a5=−22

a5=−35

Answer:

23, 25

Step-by-step explanation:

let the first number be represented as A, since there are two odd numbers, the second number would be A + 2

A + A+2 = 48

2A + 2 = 48

2A = 48 - 2

2A = 46  ( divide both sides by 2)

A = 23

since we know the next number to be A + 2

= 23 + 2 = 25

the two numbers are 23 and 25

Answer:

m<E = 1/2 ( WP - KA )

Answer:

x = √17

Step-by-step explanation:

x² = 4² + 1²

x² = 17

x = √17

x² = y² + z²

x² = 4² + 1²

x² = 16 + 1

x² = 17

Answer:

420 unique combinations

Step-by-step explanation:

Simply multiply:

2 * 5 * 6

There are 2 choices for the first set, and 5 choices for the second set. Each of the 2 choices from the first set can be combined with each of the 5 choices from the second set. So, there are 2 times 5 combinations from the first and second sets.

Answer:

A

Step-by-step explanation:

x is hour. {from the question}

k = [tex]\frac{-500+200}{5}[/tex]

[tex]=\frac{-300}{5}[/tex]

[tex]=-60[/tex]

So [tex]y=-60x+500[/tex] choose A.

I hope this helps you

:)

The function that describes the car's distance from Austin is

y = -60x + 500.

A function is a relationship between a number of inputs and outputs. A function is an association of inputs where each input is coupled with exactly one output. There is a range, codomain, and domain for every function.

Let x be the time period in hour.

And y is the distance from Austin.

We substitute the value of x =5 to the functions and see if it gives the output 200.

In A:

y = 60x -500

y = 60(5) - 500

y = -200

Distance is not negative. So, this is not a required function.

In B:

y = -60x +500

y = 200 miles.

This is a required function.

In C:

y = -40x + 500

y = -200 + 500

y = 300 miles.

This is not a required function.

In D:

y = 60x + 200

y = 300 + 200

y = 500 miles.

This is not a required function.

Therefore, y = -60x +500 is a required function.

There are three possible solutions:

Let be [tex]x[/tex], [tex]y[/tex] and [tex]z[/tex] the quantities of large, medium-sized and small candies bought by the unicorn., which represent non-negative integers. After a quick reading, we build the following system of linear equations:

[tex]x + y + z = 10[/tex]  (1)

[tex]4\cdot x +2\cdot y +z = 16[/tex]   (2)

We notice that the number of variables is greater than the number of linear equations. Thus, the system have several solutions. By (1):

[tex]z = 10 - x - y[/tex]

(1) in (2):

[tex]4\cdot x + 2\cdot y + 10 - x - y = 16[/tex]

The cash price of her purchase would be $5262.79

If n is the number of times the interested is compounded each year, and 'r' is the rate of compound interest annually, then the final amount after 't' years would be:

[tex]a = p(1 + \dfrac{r}{n})^{nt}[/tex]

The Present value = C [1 - (1+i)^(-n)]/i

C = the amount of payment per period

i = interest rate

n=number of payments

In this problem we have;

C = $174.80

i = 12% per year compounded monthly

 = 12/(12 x 100)

 = 0.01

n = 3 x 12 = 36 months

Present Value = 174.80[1  - (1+0.01)^(-36)]/0.01

Cash price = $5262.79

Hence, the cash price of her purchase would be $5262.79

m-n = 3 becomes m=3+n

Substitute 3+n to m in m+n = 5

Therefore;

2n = 2

n = 1

m - n = 3, n is 1

Step-by-step explanation:

i took the quiz :)

have a great rest of your day/night :)

Answer:

A = P(1 + r/n)nt

A is the amount accumulated, P is the principle (initial) amount, r is the decimal rate, n is the number of times interest is compounded per year, and t is the number of years.

In this question, we are solving for A, P is $1200, r is 0.03, n is 1 (because interest is compounded once per year), and t is 3 years.

Thus:

A = $1200(1 + 0.03/1)1(3) = $1200(1.03)3 = $1311.27

and

Interest earned = 1311.27 - 1200 = $111.27

Answer:

Interest earned = 1311.27 - 1200 = $111.27

Step-by-step explanation:
