Answer:

<h2>f(19) =  -  \frac{27}{7}  \\</h2>

Step-by-step explanation:

f(x) =  \frac{3}{x + 2}  -  \sqrt{x - 3}  \\

To find f(19) , substitute the value of x that's 19 into f(x). That is for every x in f (x) replace it with 19

We have

f(19) =  \frac{3}{19 + 2}  -  \sqrt{19  - 3}  \\  =  \frac{3}{21}  -  \sqrt{16}  \\  =   \frac{1}{7}  - 4 =  \frac{1 - 28}{7}

We have the final answer as

f(19) =  -  \frac{27}{7}  \\

Hope this helps you

Mr. Frank has 1.08 kilograms of fertilizer for the plants in his nursery. He wants every plant to get 93 mg of fertilizer 4 time
joja [24]

Answer: See explanation

Step-by-step explanation:

First and foremost, we should know that: 1 kilogram = 1,000,000 milligrams

Therefore, 1.08kg will be converted to milligram and this will be:

= 1.08 × 1,000,000 milligrams

= 1,080,000 milligrams

Since every plant gets 93mg of fertilizer, the number of plants that can be fertilized will be:

= 1,080,000 / 93

= 11612.903

Therefore, 11612 plants can be fertilized.

The fertilizer left over will be:

= 1,080,000 - (11612 × 93)

= 1080000mg - 1079916mg

= 84 mg
