There all 0 so zero is the answer because the first set the first 0 is slope the second 0 is the y-intercept
Answer:
this is your answer look it once
Length of the subintervals: ![[0,\frac{\pi}{2}], [\frac{\pi}{2}, \pi}]](https://tex.z-dn.net/?f=%20%5B0%2C%5Cfrac%7B%5Cpi%7D%7B2%7D%5D%2C%20%5B%5Cfrac%7B%5Cpi%7D%7B2%7D%2C%20%5Cpi%7D%5D%20)
Using Upper Riemann sum,
∑Max{f(x_i) delta(x)
![=[max{(f(x_1))+max(f(x_2))]delta(x)\\ =(3+3)\frac{\pi}{2} \\=9.42](https://tex.z-dn.net/?f=%20%3D%5Bmax%7B%28f%28x_1%29%29%2Bmax%28f%28x_2%29%29%5Ddelta%28x%29%5C%5C%20%3D%283%2B3%29%5Cfrac%7B%5Cpi%7D%7B2%7D%20%5C%5C%3D9.42%20%20)
Lower sum for n=2:
The minimum value for the function on ![[0,\frac{\pi}{2}], [\frac{\pi}{2}, \pi]](https://tex.z-dn.net/?f=%20%5B0%2C%5Cfrac%7B%5Cpi%7D%7B2%7D%5D%2C%20%5B%5Cfrac%7B%5Cpi%7D%7B2%7D%2C%20%5Cpi%5D%20)
is 2.
Answer: -91
Step-by-step explanation:
(2-5)^2-(4*5^2)
Follow the order of operations.
2-5=-3 Which uses the property of parentheses
(-3)^2-(4*5^2)
(-3)^2=9 which uses the property of exponents
5^2=25 which uses the property of exponents
9-(4*25)
4*25=100 which uses the property of multiplication
=9-100 which uses the property of subtraction
=-91
