Determine whether each statement is sometimes, always or never true.
a. A function whose graph is a straight line has a variable rate of change.
b. A quadratic function has a constant rate of change.
c. The rate of change of a linear function is negative.
d. The rate of change between two points on the
graph of a nonlinear function is 0.

Answer choices- always, sometimes, never

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.

it would rotate about 180 degrees.
