Answer:
false have a god day!
Step-by-step explanation:
Answer: 20 minutes.
Explanation:
Think of the water stream as being still (perhaps like a solid pavement), from the point of view of objects floating on the surface. (of course, from the POV of anyone standing on the banks, the water flows downstream). Think of the boat as a bike riding on the pavement. The boat just turned upstream and the hat fell into the water. In this POV, the hat lies on the surface and the boat/bike is riding away. For 20 minutes. Then (Katya realizes she lost the hat and turns back), the boat/bike needs exactly the same time, i.e., 20 minutes to come back to the hat, which rests at the same spot on the surface!
What makes the question initially confusing is the fact that the river flows with respect to the banks and one's mind is tempted to view the situation from there, which makes it much more complicated.
In physics this is referred to as choosing the suitable "frame of reference."
b = 19
substitute x = - into the equation and solve for b
5(- )² - b + 12 = 0
+ = b
= b
multiply both sides by 5 and divide by 4
b = = 19
Answer:
The correct option is:
Shaded region above dashed boundry line.
Step-by-step explanation:
The question is incomplete as the graphs are not given. Lets make the graph of the given function and you can match it with the options to see which is the solution.
We have been given the function:
y > |x + 4| - 1
This can be divided into two equations:
y > (x + 4) - 1 , y > -(x + 4) -1
Simplify both equations.
y > x + 4 - 1 , y > -x - 4 - 1
y > x + 3 , y > -x - 5
Graph both equations
The red region shows the first equation, the green region shows the second equation. The brown region satisfies the inequality.
Compare it with your graph to get the answer, i think it should shaded region above dashed boundry line
