Answer:

14.04º

Step-by-step explanation:

Since it is a right-angle triangle, we can apply the trigonometry identity.

The Tangent rule state that Tan (θ) = Opposite/Adjacent

In the diagram, the opposite (the side that is opposite of the θ) is 5 units.

The adjacent (the side that is along the θ) is 20 units.

Applying the identity,

Tan (θ) = 5/20

θ = 14.04º (nearest hundredth)

Francium has a decay rate of 50% every 22 minutes. How much of an initial amount of 4.8 grams would be left after 88 minutes?

Jlenok [28]

Answer:

0.65g

Step-by-step explanation:

Decay rate = 50%

Decay rate = 0.5

$A = Aoe {}^{ - kt}$

where Ao = initial amount at start, k = rate of decay or growth, t = time, e = euler's number and A = value at time 't'

Ao = 4.8

t = 88/44 = 4

k = 0.5

substitute these values in the equation

$A = 4.8e {}^{ - 0.5 \times 4}$

$A = 0.6496$

$A = 0.65 \: (2dp)$
