Question

Write explicit formula. a subscript n equals a subscript n minus 1 end subscript plus 15 semicolon a subscript 1 equals 8

Hint:

  • A sequence is said to be arithmetic if the common difference is always constant.
  • The General formula of any AP is a subscript n equals a subscript 1 plus left parenthesis n minus 1 right parenthesis d.

The correct answer is: a_n=15n-7


    Explanation:
    • We have given a subscript n equals a subscript n minus 1 end subscript plus 15 comma a subscript 1 equals 8
    • We have to find the explicit formula of the given sequence.
    Step 1 of 1:
    We know that the recursive formula of an AP is a subscript n equals a subscript n minus 1 end subscript plus d, where d is common difference.
    Here we have a subscript n equals a subscript n minus 1 end subscript plus 15
    So, d = 15
    Also, We have a1 = 8
    So, The explicit formula will be

    The equation 2x + 7 represents a north path on a map. Find the equation for a path that passes through the point (6, 3) and is perpendicular to the north path.

    • We have been given an equation that represents the north path on a map.
    • We have to find an equation for a path that passes through the point (6, 3) and is perpendicular to the north path.
    Step 1 of 1:

    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

    Maths-

    Are graphs of the equations parallel, perpendicular or neither?
    y equals 2 x plus 6 space straight & space y equals 1 half x plus 3

    • We have been given two equations in the question for which we have to tell are graphs of the equations parallel, perpendicular or neither.
    Step 1 of 1:
    We have given two equations

     y equals 2 x plus 6

    y equals 1 half x plus 3
    Slope of both lines are 2,1 half respectively
    Since slope are not equal then both are not parallel.
    Product of both slope is 2 cross times 1 half equals 1
    So, both are not perpendicular also.
    So,
    Both are nor parallel neither perpendicular.

    What are the horizontal asymptotes for the graph
    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 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.
