Answer:
80 degrees
Step-by-step explanation:
A triangle has 180 degrees so you have to add up the two angles with measurements you know (70 + 30= 100) and subtract 100 from 180
Answer:
Height of cactus= 3.8ft
Step-by-step explanation:
Height of palm tree= 4.9ft
Height of cactus= ?
we know, 4.9ft= 1.2ft+c
So, 4.9ft- 1.2ft= c
c= 3.8ft
SV middle line of trapezoid, so
Answer: QR=18
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.
