(2/3) PI radians = 120 degrees
If radius is 3 feet then circumference = 2* PI * 3 =

Answer:

Hence, the arc length is 2π feet or 6.28 feet.

Step-by-step explanation:

In a circle with a radius of 3 ft, an arc is intercepted by a central angle of 2π/3 radians.

If the central angle is measured in degrees than the arc length is given by:

arc length=(θ\360°)×2πr.

and if central angle is measured in radians than the arc length is given by:

arc length=θr. ( where r is the radius of the circle)

where θ is the central angle.

Hence, here we have:

r= 3 ft.

and θ=2π/3.

Hence the arc length is given by:

Arc length=(2π/3)×3=2π  feet.

Hence, the arc length is 2π feet or 2×3.14=6.28 feet.

Which graph shows the solution to the following system of inequalities x+y&gt;4 x+y &lt;3
LekaFEV [45]

Answer:

The following graph has no solution.

Step-by-step explanation:

Since , we are given a system of inequalities as:

             x+y>4

and        x+y<3

So from the two in equalities we could clearly see that in one the sum of x+y>4 while in the other the sun x+y<3 which is not possible.

This could also be seen from the graph.

The graph will not have any common region and are parallel lines.

Hence, the graph has no solution.

Which absolute value function, when graphed, will be wider than the graph of the parent function, f(x) = |x|?
Iteru [2.4K]

There is no absolute value function when graphed, will be wider than the graph of the parent function f(x) = |x|

<h3>What is an absolute value function?</h3>

An absolute value function is a function such that,

|x|=-1  when x\geq 0 and |x|=1 when x\leq 0

For the given example,

We have been given a parent function f(x) = |x|

We need to find the absolute value function, when graphed, will be wider than the graph of the parent function.

Consider the graph of all absolute value functions.

The graph of f(x) = |x| + 3 is represented blue color.

The graph of f(x) = |x − 6| is represented green color.

The graph of f(x) = |x| is represented red color.

The graph of f(x) = 9|x| is represented violet color.

From this graph, we can observe that,

f(x) = |x| + 3 is as wise as the parent absolute value function f(x) = |x| translated up by 3 units.

Similarly, the function f(x) = |x - 6| is as wise as the parent absolute value function f(x) = |x| translated right by 6 units.

This means, there is no absolute value function when graphed, which will be wider than the graph of the parent function f(x) = |x|

Answer:

a) 72

b) $259.2

Step-by-step explanation:

A- The bus travels 40 miles on 8 gallons of gasoline. The bus is traveling 360 miles in total.

360/40= 9

9*8= 72

B- $3.60 per gallon and 72 gallons in total.

3.60*72=259.2

$259.2
