Help! Determine a so that A(t)=A0a^t describes the amount of radium-223 left after t days, where A0 is the amount at time t=0. Round to six decimal places.

50x5=$250

step-by-step explanation:

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.

a reflection across the x axis and a 90 degree rotation left and right.
