Answer:
6. 300/4 feet per hour or feet/hour
7. 90/10 feet per second or feet/sec
Try simplifying the fractions though.
Step-by-step explanation:
average rate of change just means the change in distance per the change in time (per meaning divided by). what is the change in distance? 700-400 = 300. change in time is 6-2 = 4 hours. so 300/4
Same thing, change in distance is 100 - 10 feet and change in time is 40-30 seconds so the average rate of change is 90/10 feet per second
Answer:
2y-8
Step-by-step explanation:
-y-5+y+2(2y-y)-3
Do the parenthesis first
-y-5+y+2(y)-3
Multiply
-y-5+y+2y-3
Combine like terms
2y-8
Answer:
dy/dx=sec^2^(x)-(-csc^2(x)
=sec^2(x)+ csc^2(x)
so solution is E
Okay so the answer would be
Pemdas 1. parentheses: everything is already in parentheses. so next is exponents. 10×-2 is -20. and 10×6 is 60. so 4×-20 is the next step. it equals -80. and then 3×60 is 180. lastly,add -80 and 180 together. the answer should be 100 if i did that correctly.
