(a)
To find: The slope of the secants
(a)

Answer to Problem 7E
The units for the slope are
Secant | Slope |
Explanation of Solution
Given information: The below figure shows the distance-time graph for a
Calculation:
As shown in the graph the points are
The slope of the secant
So, the slope of the secant
The slope of the secant
So, the slope of the secant
The slope of the secant
So, the slope of the secant
The slope of the secant
So, the slope of the secant
Therefore, the units for the slope are
Secant | Slope |
(b)
To find: The speed at the point
(b)

Answer to Problem 7E
The speed at the point
Explanation of Solution
Given information: The below figure shows the distance-time graph for a
Calculation:
As calculated in part (a), the slope of the line joining the point nearest to the point
Therefore, the speed at the point

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? Make appropriate assumptions. DIKE CROSS SECTION OGL KEY (FOUNDATION) 2m 1m 2m 8m Figure 1: Cross section of Dyke and its foundation 1.5m from highest OGL 0.5m…arrow_forward
