b. i. Suppose f is continous on [a, b] and differentiable on (a, b). Prove that if f(x) >0 for every x e(a, b) then f increases throughout (a, b) (4 marks) ii. Find the intervals on which f(x)=2+x-x2 increases and decreases. Hence, sketch the graph of this function. (4 marks)​

(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

answer: 270

step-by-step explanation:

you have to times 200 by 1.35 to get your answer
