DISEASE SPREAD: A model for the spread of disease assumes that the rate at which disease spreads is proportional to the product of the number of people infected and the
number not infected. Assume the size of the population to be a constant. The number of
people infected is a variable. When is the disease spreading most rapidly? (Hint: Use the
equation .)

is there any photos or whatever?

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
