The graph is **increasing on the interval (-2, 1)**because the graph has a positive slope from x=-2 to x=1. It’s **decreasing at the intervals (-infinity, -2) and (1, infinity)**because the graph has a negative slope between the x values -infinity to -2 and is also decreasing between the x values of 1 and infinity.

21 feet to 8 yards write a ratio as a fraction in simplest form without any units
Dmitriy789 [7]

We know, 3 feet = 1 yard.

We have to convert feet to yards to calculate the ratio so that the final answer doesn't have any unit.

Therefore, 21 feet = \frac{21 feet}{3 feet}yards = 7 yards

Thus, the ratio

\frac{21feet}{8yards} =\frac{7yards}{8yards} =\frac{7}{8}

The fraction \frac{7}{8} is already in its simplest form.

Therefore, the given ratio as a fraction in the simplest form without any units is \frac{7}{8}

Ede4ka [16]

Answer:

The actual area of the garden is 1256 square feet.

Step-by-step explanation:

Given:

A gardener is designing a circular garden.

On the blueprint, the garden has a diameter of 16 centimeters.

The blueprint has a scale of two centimeters to five feet.

Now, to find the actual area of the garden.

Let the actual diameter of the garden be x\ feet.

And the diameter of the garden on blueprint = 16\ centimeters.

As, given:

The blueprint has a scale of two centimeters to five feet.

2 centimeters is equivalent to 5 feet.

Thus, 16 centimeters is equivalent to x\ feet.

Now, to get the actual diameter by using cross multiplication method:

\frac{2}{5} =\frac{16}{x}

By cross multiplying we get:

2x=80

Dividing both sides by 2 we get:

x=40\ feet.

<em>Thus, the actual diameter of the garden is 40 feet.</em>

Now, to get the area of the garden we get the radius and then put the formula of area:

Radius = \frac{Diameter}{2}

Radius(r)= \frac{40}{2}=20\ feet.

Area =\pi r^2.

Area=3.14\times 20^2

Area=3.14\times 400

Area=1256\ square\ feet.

Therefore, the actual area of the garden is 1256 square feet.
