E) 10.44

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
A) 2 $\le$ t $\lt$ -19
B) 2 $\lt$ t $\le$ -19
C) -19 $\le$ t$\le$ 2
D) -19 $\lt$ t $\lt$ 2
E) -19 $\le$ t $\lt$ 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.
