Designer dolls, inc. found that the number n of dolls sold varies directly with their advertising budget a and inversely with the price p of each doll. the company sold 5200 dolls when $26,000 was spent on advertising and the price of a doll was set at $30. determine the number of dolls sold when the amount spent on advertising is increased to $52,000. round to the nearest whole number.
a. 5,200 dolls
b. 1,723 dolls
c. 3,447 dolls
d. 10,400 dolls

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
