The distance between points (1, 2) and (x1, y1) is the square root of (x1 - 1)2 + (y1 - 2)2. a. true b. false

Question says that "The distance between points (1, 2) and is the square root of ."

It indicates that we need to find distance between given points (1, 2) and using distance formula then verify if the given answer is true or false.

Distance formula is

where (x1,y1) and (x2,y2) are usually given points.

Given that we have to use point (1,2)

so x2=1 and y2=2

plug these values into distance formula

Which is same as the given equation for distance.

Hence given statement is TRUE.

the answer would be the last one (constat) she stays at the same rat every two mintues it goes up by 0.4

step-by-step explanation:

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.
