Answer:
6,7
Step-by-step explanation:
Answer:
5/16
Step-by-step explanation:
This is a geometric sequence
aₙ=a₁*rⁿ⁻¹
a₆=10*.5⁶⁻¹
a₆=10*.5⁵
a₆=10*(1/2)⁻⁵
a₆=10*1/32
a₆=10/32=5/16
Answer:
Slope = 2
Step-by-step explanation:
So to find the slope we have to put it in y = mx + b form;
2y = 4x - 8
Divide both sides by 2;
y = 2x - 4
The slope is 2
Answer: a) 70 mph
b) 80 mph
Step-by-step explanation:
Given that Kayleen left home at noon and drove to boston.she got there at 4:00. Then time spent will be 4 hours . Noon means 12pm
Distance covered = 280 miles kayleens average speed will be
Speed = distance/time
Speed = 280/4 = 70 mph
Given that Elijah was already 40 miles closer than Kayleen was when she started
Distance covered by Elijah will be
Distance = 40 + 280 = 320
Time = 4 hours
Speed = 320/4 = 80 mph
