Answer:
Depends on the context however this appears to be units for area and should be simplified to 107.4m²
Step-by-step explanation:
The answer to this depends on the context. If m represents a variable where an unknown number is then you must square both 7.40 and m in the parenthesis (7.40m)^2. However, from what is written here this is an area expression and the units are meters squared or m². In this case, it does not represent a variable. You should add the areas together since they are the same unit to simplify the expression.
(7.40m)^2+100.0m^2 = 7.4m² + 100m² = 107.4m²
Answer:
The answer is .125
Step-by-step explanation:
Answer:
a) integral = 24.72
b) |Error| ≤ 0.4267
Step-by-step explanation:
a)
The integral:
can be approximated with the midpoint rule, as follows:
6.7*(0.8 - 0.0) + 8.9*(1.6 - 0.8) + 6.9*(2.4-1.6) + 8.4*(3.2 - 2.4) = 24.72
(that is, all the intervals are 0.8 units length and f(x) is evaluated in the midpoint of the interval)
b)The error bound for the midpoint rule with <em>n</em> points is:
|Error| ≤ K*(b - a)^3/(24*n^2)
where <em>b</em> and are the limits of integration of the integral and K = max |f''(x)|
Given that -5 ≤ f''(x) ≤ 1, then K = 5. Replacing into the equation:
|Error| ≤ 5*(3.2 - 0)^3/(24*4^2) = 0.4267
