NEED HELP PLEASE We described numbers in this lesson using both powers of 10 and using standard decimal value. For example, the speed of light through ice can be written as a multiple of a power of 10, such as (2.3)⋅108 meters per second, or as a value, such as 230,000,000 meters per second. Use the number line to answer questions about points A and B.
Describe point B as:

a. A multiple of a power of 10
_ x 10 ^ _
b. A value
_

Describe point A as:

a. A multiple of a power of 10
_ x 10 ^ _

b. A value
_

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

graph them on a graphing calculator, press 2nd trace. select intersect. hit enter until it says answer. ti 84 works best
