Question 16

Find the distance between the points. Round to the nearest hundredth, if necessary. (9, 6), (7, -3)

Accepted Answer

Using the distance formula, 
d = sqrt((7-9)^2 + (-3-6)^2) 
d = sqrt(4 + 81) 
d = sqrt(85) 
d ≈ 9.22 (rounded to the nearest hundredth)

Question 18

Use inequality notation to describe the set. t is at least -19 but less than 2

Accepted Answer

The inequality notation for "t is at least -19 but less than 2" is -19 ≤ t < 2, which translates to -19 ≤ t and t < 2. Choice E is the only option that correctly represents this inequality with the notation -19 ≤ t ≤ 2, which means -19 is less than or equal to t, and t is less than or equal to 2. The other options either have the wrong inequality symbols or include 2 as part of the inequality, which is incorrect.
