write an equation for the n th term of the arithmetic sequence -4, 1, 6, 11 ... Then find a(50)
an equation is: a(n) = _n-_
a(50)= _

Answers

Answer 1

Answer:

see explanation

Step-by-step explanation:

The n th term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 4 and d = a₂ - a₁ = 1 - (- 4) = 1 + 4 = 5 , thus

[tex]a_{n}[/tex] = - 4 + 5(n - 1) = - 4 + 5n - 5 = 5n - 9

Then

a(50) = 5(50) - 9 = 250 - 9 = 241

A company offers two monthly plans. Plan A costs $ 25 plus an additional $0.10 for each minute of calls. Plan B costs $18 plus an additional $0.15 for each minute of calls.

Answers

Answer:

The indifference point is 140 minutes.

Step-by-step explanation:

Giving the following information:

Plan A costs $ 25 plus an additional $0.10 for each minute of calls.

Plan B costs $18 plus an additional $0.15 for each minute of calls.

First, we need to establish the total cost formula for each plan:

Plan A= 25 + 0.1*x

Plan B= 18 + 0.15*x

x= number of minutes

Now, to calculate the indifference point, we equal both formulas and isolate x:

25 + 0.1x = 18 + 0.15x

7 = 0.05x

140=x

The indifference point is 140 minutes.

Prove:

Plan A= 25 + 0.1*140= $39

Plan B= 18 + 0.15*140= $39

Graph the linear function d(x)=−1/2x−3.

Answers

Answer:

Step-by-step explanation:

The required graph of the given function d(x)=−1/2x−3 has been shown.

Given that, to plot the graph of the linear function,  d(x)=−1/2x−3.

What is the graph?

The graph is a demonstration of curves that gives the relationship between the x and y-axis.

Here,
The graph of the liner function d(x)=−1/2x−3 can be plot by putting the values of the x in the equation which gives the value of y by calculating such an ordered pair we can plot the curve of the liner equation on the graph. i.e.
At x = 0
d(0) = -1/2 * (0) - 3
d(0) = -3
So, the ordered pair will be (0, -3).
Now, put x = 2
d(2) = -1/2 * 2 - 3
d(2) = -1 - 3
d(2) = - 4
So the ordered pair will be (2, -4)
joining these two points will show the graph of the given equation d(x)=−1/2x−3.


Thus, the required graph of the given function d(x)=−1/2x−3 has been shown.

Chris's age is 17 more than one-fourth of Brian's age. How old is Chris if Brian is 27?

Answers

Answer:

23.75

Step-by-step explanation:

Given that:

Brian's age = 27

Age of Chris is 17 more than one - fourth of Brian's age.

To find:

Age of Chris = ?

Solution:

Let age of Chris = [tex]x[/tex]

One - fourth of Brian's age =  [tex]\frac{27}{4}[/tex]

17 more than One - fourth of Brian's age = [tex]\frac{27}{4}[/tex] + 17

Therefore, we can write the equation as per question statement:

[tex]x = \frac{27}{4} + 17\\\Rightarrow x = 6.75+17\\\Rightarrow \bold{x = 23.75}[/tex]

Therefore, Chris is 23.75 years old if Brian is 27.
