The diameter of a quarter is 2.5 cm. What is it’s circumference?

anastassius [24]

Answer:

7.85 cm

Step-by-step explanation:

The circumference of a circle can be found using the following formula.

$c=\pi d$

The diameter is 2.5 centimeters. Therefore, we can substitute 2.5 cm in for d.

$c=\pi *2.5 cm$

Now, find the circumference.

- In terms of pi:

$c=\pi *2.5 cm$

$c= (2.5)\pi cm$

$c= 2.5\pi cm$

-Using 3.14 as pi

$c=\pi *2.5 cm$

$c=3.14 *2.5 cm$

$c=7.85 cm$

-Using 3.14159... as pi

$c=\pi *2.5 cm$

$c=7.85398163 cm$

Which of the following graphs model exponential functions? Select all that apply.

shusha [124]

The given graphs model exponential functions are a, b and c.

Option a, b and c are the correct answers.

To choose the graph.

<h3>What is exponential function?</h3>

A relation of the form y = ax, with the independent variable x ranging over the entire real number line as the exponent of a positive number a.

Given that:

The three graphs in the second picture are the graphs of exponential functions. You can detect it from the L shaped graphs.

The very first graph represents a linear function. A straight line always represents a linear function. In a Linear function, the change in the values of y is constant throughout in relative to change in x values.

Therefore, the given graphs a, b and c are the correct answers.
