Answer:

a. the domain is 1 ≤ x ≤ 6

b. the cost of 4 sandwhiches is $8

Step-by-step explanation:

A. The domain is all of the possible x values (the range is all of the y values)

B. By finding the x value of 4 you can then trace it up until it intersects with the slope or your data points. Then you look left and see which y-value is associated with the x-value.

I hope this was helpful! Good Luck!

the length of an arc of a circle is 269⁢πcentimeters and the measure of the corresponding central angle is 65∘. what is the leng

scZoUnD [109]

The length of the circle's radius = 744.92 cm

Given the length of arc of a circle, arc length = 269⁢π cm

Central angle of a circle is the angle made between the radius through the arc length at the center of the circle.

The corresponding central angle = 65°

To find the corresponding central angle in radians = 65° x π/180 = 13π/36 radians

We have, arc length of a circle = radius x central angle

Therefore, radius of the circle = arc length / central angle

= 269⁢π /(13π/36)

= 744.92 cm

What is the answer 9c-5=13?

riadik2000 [5.3K]

C is 2 because you have to move the 5 so you add 5 to 13 which is 18 then divide both sides by 9 so it's 2
