Answer:

f(x) = 10 + 0.5x

Where x represents the number of days.

After 17 days the plant would be 18.5 cm tall.

Step-by-step explanation:

Let x represents the number of days after which the height of the plant would be 18.5 centimeters,

Given,

The original height of the plant = 10 cm

Also, it has grown approximately 0.5 centimeter per day,

So, the total increment in height after x days = 0.5x

The final height of the plant after x days = Original height + Total increment

f(x) = 10 + 0.5x

Which is the required function.

Now, f(x) = 18.5 cm

⇒ 10 + 0.5x = 18.5

Subtracting 10 on both sides,

0.5x = 8.5

Divide both sides by 0.5,

x = 17

Hence, after 17 days the plant would be 18.5 cm tall.

Can some one help me asap

It'd be easier to do #18 if y ou were to break it up:

                                                        14* (first term + 14th term)
Sum from n=1 to 14 of n =  S      = ---------------------------------
                                               14                       2
                                    
     14(1+14)
= ---------------- = 7(15) = 105 
           2

The sum of twice that is 210.  The sum of "1 from n=1 to n=14" is just 14.

The final sum is 210 + 14 = 224 (answer)

Nikolay [14]

Answer:

4 hours

Step-by-step explanation:

The amount remaining at the end of each hour is 0.85 of the amount at the start of the hour. You want to find the exponent such that ...

... 0.85^x = 0.5 . . . . . x = the number of hours until half is left

... x·log(0.85) = log(0.5) . . . . . take the log to turn it to a linear equation

... x = log(0.5)/log(0.85) ≈ 4.265024

Rounded to the nearest  hour, x = 4.
