The radioactive element sodium-24 has a half-life of 16 hours and is used to locate obstructions in blood flow. if the procedure requires 0.60 grams to be in the blood stream at the time of the ct scan which is scheduled to take place in 2 days ( 48 hours), what minimum amount must be on hand now.

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.

you need to give us more information since we can't answer

11) obtuse

13)right

15) acute
