<h2>Answer:</h2><h2>The radius of the circle = 15.92 cm</h2>

Step-by-step explanation:

Given, the central angle of the arc = \frac{2\pi }{5} = 1.256

Length of the arc = 20 cm

Radius of the circle = ?

Radius of the circle = \frac{arc length}{central angle} = \frac{20}{1.256} = 15.92 cm

Match the following key attributes for the graph
anzhelika [568]

Answer:

Domain: [-4, ∞]

Range: [-6, ∞]

Step-by-step explanation:

The domain is the set of the possible x values

The range is the set of the possible y values.

In the graph, we can see that the function cuts in a given part. We can see that for the x-values, the smallest one is x = -4, and then the function extends to the right (we see no limit at the right, then there is none)

This means that the domain is:

D: [-4, ∞]

For the y-values, the smallest value is when x = -4, and the y-value is -6

Then we can see that, as x increases, the same happens for y.

Then the range is:

R: [-6, ∞]

Score: 16.17/50
Vesna [10]

Answer:

There will be $4450 left at the end of the year.

Step-by-step explanation:

We first take 11% and multiply it by $5,000. We get 550. This means that the account will lose $550. Next, we take our original amount, $5,000, and subtract $550 from it. We will get $4450.
