Answer: <u><em>No. of students in 9th grade = 150 </em></u>

<u><em>No. of students in 10th grade = 300</em></u>

Step-by-step explanation: Total No. of Students = 450

∴No. of students in 9th grade = 1/3 of 450

I.e. = 1/3 × 450 = 150 students in 9th grade.

<em>Let the No. of students in 10th grade be 'x'</em>

x = 450 - 150 = 300 students in 10th grade.

∴No. of Students in 9th grade = 150 students

∴No. of Students in 10th grade = 300 students

Use the definition of a derivative to find f’(x).
tatyana61 [14]

Answer:

f'(x) = -\frac{9}{x^2}

Step-by-step explanation:

i) f(x) = 9 / x

ii) f'(x)  = $\lim_{h\to 0} \frac{f(x+h) - f(x)}{h} $  \hspace{0.2cm}

        = $\lim_{h\to 0} \frac{\frac{9}{x+h}  - \frac{9}{x} }{h}  =  \hspace{0.1cm} $\lim_{h\to 0} \frac{9x - 9(x+h)}{hx(x+h)} $ \hspace{0.1cm} =  \hspace{0.1cm}$\lim_{h\to 0} \frac{-9h}{hx(x+h)}  =  $\lim_{h\to 0} \frac{-h}{x(x+h)} = \frac{-9}{x^2}$

Answer is H. p/5 = 8

Given:
1/5 of the plants in a vegetable garden are cucumber plants.
8 cucumber plants.

Find the total number of plants in the vegetable garden.

8 ÷ 1/5 = p

Steps in dividing fractions.
1) Get reciprocal of 2nd fraction. 1/5 is the 2nd fraction. Its reciprocal is 5/1

2) multiply 1st fraction to the reciprocal of the 2nd fraction
8 * 5/1 = p

3) 8*5 = p ⇒ p = 40

p * 1/5 = 8
p/5 = 8

40/5 = 8
8 = 8
