Answer:
Average value of the function over the interval is 3.
Step-by-step explanation:
Average value of the function y = 2x³ - 3x² over the interval (-1, 3) will be defined by the area under curve for the given interval divided by width of the interval.
A = 
= ![[\frac{2x^{4}}{4}-\frac{3x^{3}}{3}]^{3}_{(-1)}](https://tex.z-dn.net/?f=%5B%5Cfrac%7B2x%5E%7B4%7D%7D%7B4%7D-%5Cfrac%7B3x%5E%7B3%7D%7D%7B3%7D%5D%5E%7B3%7D_%7B%28-1%29%7D)
= ![[\frac{x^{4}}{2}]^{3}_{-1}-[x^{3}]^{3}_{-1}](https://tex.z-dn.net/?f=%5B%5Cfrac%7Bx%5E%7B4%7D%7D%7B2%7D%5D%5E%7B3%7D_%7B-1%7D-%5Bx%5E%7B3%7D%5D%5E%7B3%7D_%7B-1%7D)
= ![[\frac{3^{4}-(-1)^{4} }{2}]-[3^{3}-(-1)^{3}]](https://tex.z-dn.net/?f=%5B%5Cfrac%7B3%5E%7B4%7D-%28-1%29%5E%7B4%7D%20%7D%7B2%7D%5D-%5B3%5E%7B3%7D-%28-1%29%5E%7B3%7D%5D)
= ![[\frac{81-1}{2}]-[27+1]](https://tex.z-dn.net/?f=%5B%5Cfrac%7B81-1%7D%7B2%7D%5D-%5B27%2B1%5D)
= 
= 12
Width of the interval = 3 - (-1) = 4
Average value = 
Therefore, average value of the function over the given interval is 3.
Answer:
D
Step-by-step explanation:
Sum of interior angle = (n-2)180
900 = (n - 2)180
Opening bracket
900 = 180n - 360
180n = 900 + 360
180n = 1260
n = 1260/180
n = 7
Answer:Perimeter=5*2+2*(x-2)
Step-by-step explanation:
Because perimeter =2*length+2*width
1)Simplify 3\times 1043×104 to 312312
312-5\times 102312−5×102
2)Simplify 5\times 1025×102 to 510510
312-510312−510
3)Simplify
-198−198
rise is 5 - - 4 = 5 + 4.
Thus, the rise of the points is 9.
