Answer:
38
Step-by-step explanation:
This is a right handed limit because there is a "+" next to the -19. This means that we have to find the limit as the function goes to -19 from the right side. This means that the limit is when it goes from -19.1 --> -19.
From the table we see that this area is aproaching 38 as it gets closer to -19.
The f(x) number will get increasingly closer to 38 but never reach 38, and that is why it is the limit.
Hope this helps!!!
Answer:
160 mph
Step-by-step explanation:
The relationship between time, speed, and distance is ...
time = distance/speed
__
If p represents the plane's speed, then the speed with the wind is p+20 and the time to go 405 miles is ...
405/(p+20)
The speed against the wind is p-20, and the time to go 315 miles is ...
315/(p-20)
These two times are equal, so we have ...
405/(p+20) = 315/(p-20)
405(p-20) = 315(p+20) . . . . . . cross multiply
90p = 6300 +8100 = 14400 . . . . add 8100 -315p
p = 14400/90 = 160
The speed of the plane in still air is 160 mph.
Answer:
5 and 6 as well as 2 and 3
Step-by-step explanation:
Answer:
V=1/3hπr². Basically, 1/3 x height x 3.14 (pi) x radius squared.
Step-by-step explanation:
The formula of figure 2 would be 1/3 x 15 x 3.14 x 8 squared. The volume of figure 2 would be 1005.30965
the formula for figure 3 would be 1/3 x 15 x 3.14 x 4 squared. The volume of it would be 251.32741
hope this helps! (Also please make me brainliest if this helps u :) )
