The scatter plot shows a hiker's elevation above sea level during a hike from the base to the top of a mountain. The equation of a trend line for the hiker's elevation is y equals=9.069.06xplus+651651, where x represents the number of minutes and y represents the hiker's elevation in feet. Use the equation of the trend line to estimate the hiker's elevation after 175 minutes.
Answers
Answer:
2236.5
Step-by-step explanation:
The regression equation for predicting hiker's elevation is
y=9.06x+651.
Here x is the number of minutes.
We wish to estimate hiker's elevation after 175 minutes. For this purpose we put x=175 in the predicted regression equation.
y=9.06(175)+651
y=1585.5+651
y=2236.5
Thus, the hiker's elevation after 175 minutes is 2236.5 feet.

In Bear Creek Bay in July, high tide is at 1:00 pm. The water level at high tide is 7 feet at high tide and 1 foot at low tide. Assuming the next high tide is exactly 12 hours later and the height of the water can be modeled by a cosine curve, find an equation for Bear Creek Bay's water level in July as a function of time (t).

Add x on both sides.
3 - x + x = 5 + x
3 = 5 + x
Subtract 5 on both sides
3 - 5 = 5 - 5 + x
3 - 5 = x
x = 3 - 5
x = -2

Well, technically, you've only told us the time to travel across
our galaxy, so we don't have enough information to calculate
anything about its length.
Fortunately, some of us are vaguely aware that our galaxy is
roughly round, at least in its plane. So "across" means its diameter,
and that's the same in any direction through the center.
Relieved, we can now proceed to calculate:
(3 x 10⁸ meter/sec) x (8.64 x 10⁴ sec/day)
x (3.65 x 10² day/yr) x (10⁵ years)
= (3 x 8.64 x 3.65 x 10¹⁹) meters
= 94.608 x 10¹⁹ meters
= 946,080,000,000,000,000,000 meters
(about 587,867,000,000,000,000,000 miles) .
