The sales of lawn mowers t years after a particular model is introduced is given by the function y = 5500 ln(9t + 4), where y is
Nimfa-mama [501]

Given:

The function is:

y=5500\ln (9t+4)

Where y is the sales of lawn mowers t years after a particular model is introduced.

To find:

How many mowers will be sold 3 years after a model is introduced?

Solution:

We have,

y=5500\ln (9t+4)

Substituting t=3, we get

y=5500\ln (9(3)+4)

y=5500\ln (27+4)

y=5500\ln (31)

On substituting the approximate value of ln(31), we get

y=5500\times 3.433987

y=18886.9285

y\approx 18887

Therefore, the 18887 mowers will be sold 3 years after a model is introduced.

-1/2 divided by what equals -7/3
marshall27 [118]
(-1/2)/x = -7/3

*multiply both sides by x

(-1/2) = (-7/3)x

*divide both sides by (-7/3)

(-1/2)/(-7/3) = x

dividing by a fraction is the same as multiplying by it's reciprocal:

x = (-1/2)*(-3/7)

* the negative signs cancel

x = (1/2)*(3/7)

x = (1*3)/(2*7)

<u><em>x = 3/14</em></u>
