To solve this problem you must apply the proccedure shown below:
 1. You have the following functions given in the problem above:
 f(x)=x-6 &#10; and g(x)=x1/2(x+3)=x(x+3)/2<span>
 2. You have that g(x) times f(x) can be written as g(x)*f(x). Therefore, you must multiply f(x) * g(x), as following:
 </span>g(x)*f(x)=(x-6)*x(x+3)/2<span>
 3. Applying the distributive property, you have:
</span> g(x)*f(x)=( x^{3} + 3x^2 - 6x^{2} -18x)/2
 g(x)*f(x)=(x^{3} - 3x^{2} -18x)/2
 The answer is:  g(x)*f(x)=(x^{3} - 3x^{2} -18x)/2

anastassius [24]

Answer:

b. About how many shoppers received ​$5 off their first​ purchase?

25% out of 230, so:

230\frac{25}{100} = 230\frac{1}{4} = \frac{230}{4} = 57.5

About 58 shoppers, that is \frac{230}{4} received ​$5 off their first​ purchase.

How to figure out how to do this problem
padilas [110]
The circumference should be 37.68 because area= pi *r^2. So if area=pi*36, then the radius must be 6 which makes the diameter 12 and circumference=pi*diameter and 3.14*12= 37.68. So circumference of the circle is 37.68!
