15. The table shows the minimum and maximum
elevations, relative to sea level, of several
hiking trails. Which hiking trail has the least
change in elevation, related to sea level?
Explain how you solved.
Answers
The hiking trail that has the least change in elevation, related to sea level, is:
Southern Moon.
Which trail has the least change in altitude?The change in altitude of each trail is calculated as the subtraction of the highest altitude by the lowest altitude, that is:
Change in elevation = highest altitude - lowest altitude.
For Eastern Point, the change is given as follows:
Change = 78 - (-85) = 78 + 85 = 163 feet.
(subtracting by a negative is the same as adding to the positive of the number).
For Northern Star, the change is given as follows:
Change = 34 - (-150) = 34 + 150 = 184 feet.
For Southern Moon, the change is calculated as follows:
Change = 48 - (-62) = 48 + 62 = 110 feet.
The smallest amount is of 110, hence Southern Moon has the least change in elevation relative to sea level.

Answers
The inequality which is represented by the dashed line and the description as in the task content is; y < Negative three-halvesx + 1.
Which inequality correctly represents the dashed line as described in the task content?It follows from the task content that the inequality which correctly represents the line is to be determined.
Therefore, first, the slope which is the rate of change of y to x according to the two points given is;
slope, m = (y2 - y1)/(x2 - x1)
m = (-2 - 1)/(2 - 0)
m = -3/2.
Also, since the point, (0, 1) is given, the y-intercept of the line is; 1.
Therefore the equation of the dashed line is;
y = (-3/2)x + 1.
And ultimately, since the line is dashed and everything to the left is shaded, the required inequality is;
y < (-3/2)x + 1.

Step-by-step explanation:
Find and classify the global extrema of the following function:
f(x) = -x^3 + 5 x^2 + x
Find the critical points of f(x):
Compute the critical points of -x^3 + 5 x^2 + x
To find all critical points, first compute f'(x):
d/(dx) (-x^3 + 5 x^2 + x) = -3 x^2 + 10 x + 1:
f'(x) = -3 x^2 + 10 x + 1
Solving -3 x^2 + 10 x + 1 = 0 yields x = 1/3 (5 - 2 sqrt(7)) or x = 1/3 (5 + 2 sqrt(7)):
x = 1/3 (5 - 2 sqrt(7)), x = 1/3 (5 + 2 sqrt(7))
f'(x) exists everywhere:
-3 x^2 + 10 x + 1 exists everywhere
The critical points of -x^3 + 5 x^2 + x occur at x = 1/3 (5 - 2 sqrt(7)) and x = 1/3 (5 + 2 sqrt(7)):
x = 1/3 (5 - 2 sqrt(7)), x = 1/3 (5 + 2 sqrt(7))
The domain of -x^3 + 5 x^2 + x is R:
The endpoints of R are x = -∞ and ∞
Evaluate -x^3 + 5 x^2 + x at x = -∞, 1/3 (5 - 2 sqrt(7)), 1/3 (5 + 2 sqrt(7)) and ∞:
The open endpoints of the domain are marked in gray
x | f(x)
-∞ | ∞
1/3 (5 - 2 sqrt(7)) | -0.0490425
1/3 (5 + 2 sqrt(7)) | 21.9009
∞ | -∞
The largest value corresponds to a global maximum, and the smallest value corresponds to a global minimum:
The open endpoints of the domain are marked in gray
x | f(x) | extrema type
-∞ | ∞ | global max
1/3 (5 - 2 sqrt(7)) | -0.0490425 | neither
1/3 (5 + 2 sqrt(7)) | 21.9009 | neither
∞ | -∞ | global min
Remove the points x = -∞ and ∞ from the table
These cannot be global extrema, as the value of f(x) here is never achieved:
x | f(x) | extrema type
1/3 (5 - 2 sqrt(7)) | -0.0490425 | neither
1/3 (5 + 2 sqrt(7)) | 21.9009 | neither

The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. A dilation in mathematics is a function f from a metric space M into itself that, for all points x, y in M, satisfies the identity d=rd, where d is the distance between x and y and r is some positive real number.

What is the slope of the ramp from the ground to the landing? Write your answer as a fraction with a whole-number numerator and denominator.
Answers
The slope of the ramp is m = h/√(r² - h²).
What is mean by square root of a number?
A square root of a number is a value that multiplied by itself gives the same number.
Let h = height of the landing.
And, r = the length of the ramp.
Then, the length from the ground where the ramp touches it, to the ground directly below the landing is
⇒ √(r² - h²)
And, The slope of the ramp is m = h/√(r² - h²)
For example, if the ramp is 5 meters long and the landing height is 3 meters high, the slope of the ramp is 3/4.
As, Slope of the ramp (m) = 3/√(25-9) = 3/√16 = 3/4
Thus, The slope of the ramp is m = h/√(r² - h²).
