Answer:
Step-by-step explanation:
The amplitude (A) and the mean (M) temperature are given by:
The mean temperature, 45 degrees. occurs at midnight (t=0) and the frequency is f=24h. Therefore, the temperature D, in degrees, as a function of t, in hours, is:
This corresponds to a sinusoidal graph, we have:
Radius= 20 feet, that corresponds to the amplitud (A)
One revolution takes 24 seconds, that corresponds to the period
Min= 3 feet
k=360/24=15
D= bottom distance+ amplitud=3+20=23 feet
Then, let x be the time, in seconds:
a) To determine Reid's height after 1 minute= 60 seconds, substitute x=60
b) To determine when Reid's height will first reach 18 feet, we have to substitute y=18 feet, and isolate x:
One-fifth means
so one-fifth of 14 is just one-fifth * 14. 1/5*14=14/5.
One-fourth means 0.25 or a quarter so 0.25*-60 or 1/4*-60=-60/4=-15.
Answer:
After controversy over the location of a capital, the Dakota Territory was split in two and divided into North and South in 1889. Later that year, on November 2, North Dakota and South Dakota were admitted to the Union as the 39th and 40th states. This vast territory was one of the last American regions to be settled.
If 8 ducks are for $23.60, then one duck would be:
23.60 <span>÷ 8
</span>2.95
So one duck would be $2.95.
I hope that's correct, good luck.
