Question

Write a recursive formula for the given sequence. 47, 39, 31, 23, 15, ....

Hint:

  • Recursive Formula is a formula that defines the each term of sequence using the previous/preceding terms.

The correct answer is: a_n=a_(n-1)-8.


    Explanation:
    • We have given a sequence 47,39,31,23,15,...
    • We have to find the recursive formula.
    Step 1 of 1:
    We have given a sequence 47, 39, 31, 23, 15, ....
    The given sequence is an AP.
    We know that the recursive formula for any AP is a subscript n equals a subscript n minus 1 end subscript plus d, where d is common difference.
    Here the common difference is - 8
    So, The recursive formula is

    a subscript n equals a subscript n minus 1 end subscript plus d

    a subscript n equals a subscript n minus 1 end subscript minus 8

    How do you find vertical and horizontal asymptotes of a rational function?
    What are the vertical asymptotes for the graph of f left parenthesis x right parenthesis equals fraction numerator 3 x minus 2 over denominator x squared plus 7 x plus 12 end fraction

    1. Find the asymptotes of the rational function, if any.
    2. Draw the asymptotes as dotted lines.
    3. Find the x -intercept (s) and y -intercept of the rational function, if any.
    4. Find the values of y for several different values of x .
    5. Plot the points and draw a smooth curve to connect the points. Make sure that the graph does not cross the vertical asymptotes.
    The vertical asymptote of a rational function is x -value where the denominator of the function is zero. Equate the denominator to zero and find the value of x .
    x2 +7x + 12 = 0
    x2 + 3x + 4x + 12 = 0
    x(x + 3) + 4 (x + 3) = 0
    (x + 3)(x + 4)=0
    x= -3  or  x = -4
    The vertical asymptote of the rational function is x=−3 and x=-4
    This function has no x -intercept at (4,0) and y -intercept at (0,7) . We will find more points on the function and graph the function.


    From the graph we can analyze that the vertical asymptote of the rational function is  x= -3 and x = -4.

    The cost to rent a bike is $28 for the first day plus $2 for each day after that. Write an explicit formula for the rental cost for n days. What is the cost of renting a bike for 8 days?

    Maths-General
    • We have given a cost of rent of bike $28 for the first day plus$2 for each day after that.
    • We have to write an explicit formula for the rental cost for n days and cost of renting bike for 8 days.
    Step 1 of 2:
    We have given first day cost is $28 and for each more day $2 will be charged
    Here

    Write an equation of the line that passes through the point (4, 5) and is perpendicular to the graph of y = 2x + 3

    • We have to write an equation of the line that passes through the point (4, 5) and is perpendicular to the graph of 𝑦 = 2𝑥 + 3.
    Step 1 of 1:
    We have to find a line passes through a point (4, 5) and perpendicular to a line 𝑦 = 2𝑥 + 3.
    Since product of two perpendicular lines is equal to -1.
    So,

     m cross times 2 equals negative 1

    m equals fraction numerator negative 1 over denominator 2 end fraction
    Therefore the equation of the line will be

     y minus 5 equals fraction numerator negative 1 over denominator 2 end fraction left parenthesis x minus 4 right parenthesis

    y equals fraction numerator negative 1 over denominator 2 end fraction x plus 7
