Dennis stood on a 9 foot ladder to measure the sunflower. How much taller is the tallest sunflower than the ladder?
Shalnov [3]

Answer:

See Explanation

Step-by-step explanation:

Given

Ladder = 9ft

Tallest\ Sunflower = x

Required

How much taller is the tallest

To get this, we simply calculate the difference between the height of the tallest sunflower and the ladder.

i.e.

Difference  = Tallest\ Sunflower - Ladder

Difference  = x - 9

-----------------------------------------------------------------------------------------------------

If for instance, the tallest is 13ft, then it is 4ft taller.

Because:

Difference = 13ft - 9ft

Difference = 4ft

All polynomials have at least one maximum.<br> O A. True<br> O B. False
Advocard [28]

Answer: B) False

A counter-example would be the cubic polynomial y = x^3 which doesn't have a max or a min. The graph stretches forever in both directions (up and down) indicating that the range is the set of all real numbers.

a medication prescription states 1/4 tablet twice a day per 20kg the peson weight is 211 pounds. how many tablets should be take
Black_prince [1.1K]
<h2>Hello!</h2>

The answer is: 1.187 tablets each time (twice a day)

<h2>Why?</h2>

From the statement we know that 0.25 tablet (1/4) should be taken twice a day per 20 kg, it makes 0.5 table a day, per 20 kg.

First, we need to convert the given weight unit (pounds) to kg:

1 Pound=0.45Kg

So,

211Pounds*\frac{0.45Kg}{1Pound}= 94.95Kg=95Kg

A weight of 95 Kg, means 4.75 times more than the given information of 0.5 table a day, per 20 Kg

\frac{95Kg}{20Kg}=4.75

Then,

4.75*(0.5)=2.375

So,

For a weight of 95 Kg,  2.375  tablets should be taken a day, or 1.187  tablets each time.

Have a nice day!
