Delta x = (b - a)/n delta x = (16 - 0)/8 delta x = 2 right-hand riemann sum = 2(2.1 + 1.9 + 2.3 + 2.4 + 2.7 + 2.9 + 3.1 + 4.5) = 2(21.9) = 43.8 i am told that s(t) is in "thousands of gallons per hour," and t is only in minutes, so i suspect that 43.8 is not the end of this problem. should i understand this as 43.8 thousand gallons, or does something else need to be done?

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180

60 for the first and 130 for the second
