Answer:
Using the distance formula, when I plugged in the information, the answer I got was the square root of 85. (B)
explanation:
C(x₁ , y₁) and T(x₂ , y₂) OR C(0,4) and T(-6,-3)
CT=√[(x₂ - x₁)² + (y₂ - y₁)²] =√[(-6-0)² + (-3 - 4)²]
CT=√[(36) + (49)} = CT = √85
I’m pretty sure the answer is 9 to 1
Answer:
From the information provided you cannot conclude whether or not G-1 is a function. You would need more coordinates in the set to conclude this answer.
40 mph would be 120 miles in 3 hours (120/40)
80 mph is 120 miles in 1.5 hours(120/80)
3 - 1.5 = 1.5, not 3 hrs
Change the speed to 20 mph( 1/2 the speed) to double the hours.
20 mph = 6 hours(120/20)
40 mph = 3 hrs(120/40)
6 - 3 = 3 hours difference
