Answer:

  write factor pairs of 3^4

Step-by-step explanation:

Take the anti-log, then identify integer factor pairs of the number on the right side of the equal sign. One of the factors in each pair is the value of "a", the other is the value of "b".

_____

<em>The solution you didn't want to see</em>

Take the antilog:

  ab = 3^4

Find factor pairs of 3^4:

  3^4 = 1×81 = 3×27 = 9×9 = 27×3 = 81×1

Possible solutions are ...

  (a, b) ∈ {(1, 81), (3, 27), (9, 9), (27, 3), (81, 1)}

There is a line through the origin that divides the region bounded by the parabola and the x-axis into two regions with equal ar
jasenka [17]

Using the slope line formula,

The slope of line y = mx is 1.0315.

We have given that,

parabola equation is y = 5x - 3x²

line passing through origin is in the form of y = mx

==> mx = 5x - 3x²

==> 3x²+ mx - 5x = 0

==> 3x² + x(m -5) = 0

==> x(3x + (m -5)) = 0

==> x = 0 , x = (5 -m)/3

The total area of the bounded region is then the integral of 5x - 3x² from x = 0 to x = (5-m)/3

Area under y = 5x - 3x2 and y = mx is (125/54)/2 = 125/108

==> [0 to (5 -m)/3] ∫(5x - 3x²-mx )dx = 125/108

==> [0 to (5 -m)/3]∫( (5 - m)x - 3x2 )dx = 125/108

==> [0 to (5 -m)/3] ((5 - m)x²/2 - x³ )= 125/108

==> (5 - m)[(5 -m)/3]²/2 - ((5 -m)/3)³ = 125/108

==> (5 -m)³/18 - (5 -m)³/27 = 125/108

==> (5 -m)³/54 = 125/108

==> (5 -m)³ = 125/2

==> (5 -m) = 3.9685

==> m = 5 - 3.9685

==> m = 1.0315

Hence slope of line = 1.0315
