Abigail drives at an average speed of 60 miles per hour for 3 hours. the graph shows her distance versus time. which statements are true? check all that apply.

as abigail’s time increases, her distance increases.
as abigail’s time increases, her distance decreases.
at 2 hours, abigail has traveled 120 miles.
at 1.5 hours, abigail has traveled 100 miles.
at 3 hours, abigail has traveled 180 miles.

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,

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
