Mounting Climbing Several mountain climbers are located in a mountain pass between two peaks. The angles of elevation to the two peaks are
(a) Find the angle between the two lines.
(b) Approximate the amount of vertical climb that is necessary to reach the summit of each peak.

(a)
To find:
The angle between the two lines.
Answer to Problem 1PS
Solution:
The angle between the two lines is
Explanation of Solution
Given:
The angle of elevation to the two peaks are
The given diagram is shown in figure
Figure
Approach:
The sum of the angle of elevations of the two peaks and the angle between the sight to the peaks is equal to
Calculation:
Suppose the angle between two lines of sight to the peaks be
So the total of the all angles must be equal to
Therefore, the angle between the two lines is

(b)
To find:
The Approximate amount of vertical climb that is necessary to reach the summit of each peak.
Answer to Problem 1PS
Solution:
The Approximate amount of vertical climb to the peak is
Explanation of Solution
Approach:
The formula of
Here,
And the value of
Calculation:
Suppose the vertical climb for the first peak is
Consider, the vertical climb for the second peak be
Therefore, the approximate amount of vertical climb to the peak is

- A tank contains 200 gal of fresh water. A solution containing 4 lb/gal of soluble lawn fertilizer runs into the tank at the rate of 1 gal/min, and the mixture is pumped out of the tank at the rate of 5 gal/min. Find the maximum amount of fertilizer in the tank and the time required to reach the maximum. Find the time required to reach the maximum amount of fertilizer in the tank. t= min (Type an integer or decimal rounded to the nearest tenth as needed.)arrow_forwardThumbi Irrigation Scheme in Mzimba district is under threat of flooding. In order to mitigate against the problem, authorities have decided to construct a flood protection bund (Dyke). Figure 1 is a cross section of a 300m long proposed dyke; together with its foundation (key). Survey data for the proposed site of the dyke are presented in Table 1. Table 2 provides swelling and shrinkage factors for the fill material that has been proposed. The dyke dimensions that are given are for a compacted fill. (1) Assume you are in the design office, use both the Simpson Rule and Trapezoidal Rule to compute the total volume of earthworks required. (Assume both the dyke and the key will use the same material). (2) If you are a Contractor, how many days will it take to finish hauling the computed earthworks using 3 tippers of 12m³ each?
