Jake forgot to replace the cap on a bottle of deodorant. The deodorant began to evaporate at the rate of 12% per day. If the ori

ginal amount of deodorant in the bottle was 30 grams, which of the following graphs best represents the amount of deodorant f(x) that would remain in the bottle after x days?
graph of function f of x equals 30 multiplied by 0.88 to the power of x
graph of exponential function going down from left to right in quadrant 1 through the point 0, 40 and approaching the x axis
graph of function f of x equals 50 multiplied by 0.82 to the power of x
graph of exponential function going down from left to right in quadrant 1 through the point 0, 4 and approaching the x axis

Answer:

1.  Graph of function f of x equals 30 multiplied by 0.88 to the power of x

Step-by-step explanation:

We are given that,

Original amount of deodorant in the bottle = 30 grams

The rate of evaporation = 12% = 0.12

That is, we see that the deodorant is decreasing as the number of days increases.

So, the function form of the decrease in the amount of deodorant is given by,

f(x)=30(1-0.12)^x, where x is the number of days.

i.e. f(x)=30(0.88)^x, where x is the number of days.

Hence, the graph representing the amount of deodorant after x number of days is,

1.  Graph of function f of x equals 30 multiplied by 0.88 to the power of x

For 17a-17c, choose Yes or No to indicate wheter a zero must be written in the dividend to find the quotient.
Simora [160]

Answer:

a) yes b) no c) no

Step-by-step explanation:

In order to know this, remember something: to do the division between a number and a rational number like this and with zero to the left, the best way to solve them is converting these number to a natural number.

To do that, you only need to multiply the number by 10, 100, 1000, depending of how many decimals it have.

In case a) 0.05 has two decimals, therefore we multiply by 100:

0.05 * 100 = 5

However, when you do that, you have to do the same thing with the number in the dividend, in this case, 1.4:

1.4 * 100 = 140

So we can conclude that 1.4 you have to add a zero to do the division.

Case b) and c) do not apply, in both cases we multiply by 10 and we get this:

25.2 and 6,

26.1 and 3.

A ​used-boat dealership buys a boat for ​$2800 and then sells it for ​$4000. What is the percent​ increase?
Rudik [331]

Answer:

Step-by-step explanation:

percent increase = increase divided by original number x 100

                           

increase is the difference between the two numbers...

new number - original number.....4000 - 2800 = 1200

percent increase = (1200 / 2800) x 100

                            = 0.42857 (round to .4286) x 100

                             = 42.86 %.....if you need it rounded to the nearest percent, it      would be 43% increase

9.   she spends 1 hour total  and 1/2 hour on spanish. So she has another 1/2  on another subject ( as she spends equal time on each subject)

So number of subjects = 1 / 1/2 = 1 * 2 = 2
