Answer:
- boat: 15 mph
- current: 5 mph
Step-by-step explanation:
The relation between time, speed, and distance is ...
speed = distance/time
__
The speed downstream is ...
downstream speed = (100 mi)/(5 h) = 20 mi/h
The speed upstream is ...
upstream speed = (100 mi)/(10 h) = 10 mi/h
The boat's speed in still water is the average of these:
boat speed = ((downstream speed) + (upstream speed))/2 = (20 +10)/2 mi/h
boat speed = 15 mi/h
__
The speed of the current is the difference between the travel speed and the boat speed:
current speed = downstream speed - boat speed
= (20 mi/h) - (15 mi/h)
current speed = 5 mi/h
If the brackets need to be a square term of the form (x+h)^2
then
just half the co-efficient of x term and square it.
So here it will be
(-6)/2 = -3
squaring it, (-3)^2 = 9
so 9 is what goes in the blank to make the bracket () of the form (x+h)^2
Answer:
3
Step-by-step explanation:
I'm assuming you're saying the value of x is -1?
y-3=2(-1+1)
y-3=2(0)
y-3=0
y=3
The Median is 11, and it is shown by the line on the middle of the rectangle.
The range is 12, and you can find it by subtracting the highest data point (17) by the lowest data point (5).
The 25th percentile is 9, and it could be found by looking at the first line in the rectangle.
The 75th percentile is 14, and it could bee found by looking at the last line in the rectangle.
The inter-quartile range is 5, and it can be found by subtracting the upper quartile, or the 75th percentile (14) by the lower quartile, or the 25th percentile (9). 14-9=5
Hopefully this helps.
Answer:
greater than
Step-by-step explanation:
An exponential growth function has a base that is__greater than__one.
If the base is less than one, it will be a decay function.
Note: the above assumes an exponent greater than one as well.
