aniked [119]4 years ago
6 0

Answer:

- 3

Step-by-step explanation:

Differentiate f(x) using the power rule

\frac{d}{dx}(ax^{n} ) = nax^{n-1}

Given f(x) = \frac{3}{x} = 3x^{-1}, then

f'(x) = - 3x^{-2} = - \frac{3}{x^2}

f'(1) = - \frac{3}{1} = - 3

Several friends bought flowers to make table centerpieces. write the ratios of purple flowers to white flowers for each friend.
Zina [86]

The ratio for Rowan = <u>4:1</u>.

The ratio for Marcia = <u>10:1</u>.

The ratio for Jillian = <u>5:1</u>.

The ratio for Lulua = <u>6:1</u>.

The smallest ratio among these for purple to white flowers is for Rowan, that is, <u>4:1</u>.

Ratios are fractions in the simplest form representing the relationship between two quantities.

The ratio of purple to white flowers for each friend can be shown as:-

Rowan:

The number of purple flowers = 8

The number of white flowers = 2

Thus, the fraction of purple to white flowers = 8/2 = 4/1.

Thus, the ratio for Rowan = 4:1.

Marcia:

The number of purple flowers = 10

The number of white flowers = 1

Thus, the fraction of purple to white flowers = 10/1.

Thus, the ratio for Marcia = 10:1.

Jillian:

The number of purple flowers = 10

The number of white flowers = 2

Thus, the fraction of purple to white flowers = 10/2 = 5/1.

Thus, the ratio for Jillian = 5:1.

Lulua:

The number of purple flowers = 18

The number of white flowers = 3

Thus, the fraction of purple to white flowers = 18/3 = 6/1.

Thus, the ratio for Lulua = 6:1.

The smallest ratio among these for purple to white flowers is for Rowan, that is, <u>4:1</u>.
