Answer:
The correct option is;
C. (1.6, 1.3)
Step-by-step explanation:
Given that at x = 1.5 the y-values of both equations are y = 1.5 and y = 1 respectively
The x-value > The y-value
The difference in the y-values = 1.5 - 1 = 0.5
At x = 1.6 the y-values of both equations are y = 1.2 and y = 1.4 respectively
The x-value > The y-value
The difference in the y-values = 1.2 - 1.4 = -0.2
At x = 1.7 the y-values of both equations are y = 0.9 and y = 1.8 respectively
The x-value > The first y-value and the x-value < the second y-value
The difference in the y-values = 0.9 - 1.8 = 0.9
Therefore, the approximate y-value can be found by taking the average of both y-values when x = 1.6 where the difference in the y-values is least as follows;
Average y-value at x = 1.6 = (1.2 + 1.4)/2 = 1.3
Therefore, the best approximation of the exact solution is (1.6, 1.3)
By calculation, we have;
-3·x + 6 = 4·x - 5
∴ 7·x = 11
x = 11/7 ≈ 1.57
y = 4 × 11/7 - 5 ≈ 1.29
The solution is (1.57, 1.29)
Answer:
c = 6√2
Step-by-step explanation:
The following data were obtained from the question:
Angle θ = 30°
Opposite = 3√2
Hypothenus = c
The value of 'c' can be obtained by using the sine ratio as shown below:
Sine θ = Opposite /Hypothenus
Sine 30° = 3√2/c
Cross multiply
c × sine 30° = 3√2
Divide both side by sine 30°
c = 3√2 / sine 30°
But: sine 30° = 1/2
c = 3√2 / sine 30°
c = 3√2 ÷ 1/2
c = 3√2 × 2
c = 6√2 yard
Therefore, the value of 'c' is 6√2 yard.
