6n + 28 because the difference is 12 so if u half that to get the second it’s 6 hence 6n and then u have to add 6 to 22 to get 28 and it’s a positive number so therefore the expression is 6n+ 28

Answer:

an = 22 -6(n -1)

Step-by-step explanation:

The first term of the sequence is given as a1 = 22. The general term of an arithmetic sequence is ...

an = a1 +d(n -1) . . . . n-th term for first term a1 and common difference d

The third term will be ...

a3 = 10 = 22 +d(3 -1)

Then the common difference is ...

10 -22 = 2d

-12/2 = d = -6

Putting the known values into the formula for the general term, it becomes ...

an = 22 -6(n -1)

This can be simplified to ...

an = 28 -6n

NemiM [27]

Answer:

the plans can go 560 miles per hour and in 10 hours it can travel 5600 miles

Step-by-step explanation:

1st divide miles over hour so you have to do 3360/6 and the solution you get for that equation is how far the plane can go in miles per hour 2nd for the second question you have to multiply your unit rate by the 10 hours so since our unit rate was 560 miles per hour you would multiply 360 and 10.

What s the length of the arc for the half circle

Andrej [43]

Answer`Step-by-step explanation:

The length of an arc depends on the radius of a circle and the central angle Θ. We know that for the angle equal to 360 degrees (2π), the arc length is equal to circumference. Hence, as the proportion between angle and arc length is constant, we can say that:
