An infectious disease specialist is studying the effect of a new antibiotic on a bacterial infection. The number of bacteria in the culture on day 1 is estimated at 400000. A dose of antibiotic is applied to the culture. At the end of 1 week, the number of bacteria in the culture is estimated at 6250. The study is discontinued at the end of 2 weeks and the antibiotic is deemed effective because the estimated number of bacteria was just under 50.

c. side angle side. u shares the same sides

i think the amount would be $140.62

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.
