I need help with these questions

1.

Use summation properties and formulas to rewrite and evaluate the sum. 33 Z [(2102 7k] 3921 l: Use part I of the Fundamental Theorem of Calculus to find the derivative of h(a:) = [5111\") (cos(t4) + t)dt 5 W: [NOTE: Enter a function as your answer. Make sure that your syntax is correct, i.e. remember to put all the necessary *, (, ), etc. ] Evaluate the integral (2x + 5) (202 + 5x + 10) doc by making the substitution u = x + 5x + 10. + C NOTE: Your answer should be in terms of a and not u.Find the area of the region enclosed by y = 3.75:1: and m = 8 y2. Q Use horizontal strips to find the area, that is, integrate with respect to y. First find the y coordinates of the two points where y = 3.7556 meets a: = 8 y2. lower limit c = C] and upper limit d = C] d To find the area of the enclosed region from c to d we will integrate: / g(y)dy where g( y ) = C :J Evaluate the definite integral to find Area = C]
