Answer:
Total área: 9+9+8+6= 32 mm^2
Step-by-step explanation:
Square = 3x3 = 9mm^2
Triangle= Heigh: sqrt (3^2+3^2) = 9 and base=3
A = (9x3)/2 = 9mm^2
Rectangle= 4x2= 8mm^2
Triangle (high: 5-2=3)
(4x3)/2 = 6mm^2
Total area
Answer:
1.No- that just means that the numbers on that side are smaller
Step-by-step explanation:
For f(x) = 12/(1+x²), and subinterval width 4, you are to evaluate f(1), f(5), and f(9) and combine them according to the rule
... Integral ≈ (4/3)(f(1) + 4·f(5) + f(9)) = (4/3)(6.0000 + 4·0.4615 + 0.1463) ≈ 10.66
_____
Simpson's rule has you combine values of f(x) with coefficients 1, 4, 2, 4, ..., 2, 4, 1, where those values are evenly spaced at the edges of an even number of subintervals. Since we have only 3 values to combine, there are no terms that have a coefficient of 2. The entire sum is multiplied by 1/3 the subinterval width.
-6+3= -3
3/7+2/7=5/7
The answer is -3 5/7
