The half-life of cesium-137 is 30 years. Suppose we have a

VMariaS [17]

(a) If $y(t)$ is the mass (in mg) remaining after $t$ years, then $y(t) = y(0) e^{kt}=100e^{kt}.$

$y(30) = 100 e^{30k} = \frac{1}{2}(100) \implies e^{30k} = \frac{1}{2} \implies k = -(\ln 2) /30 \implies \\ \\
y(t) = 100e^{-(\ln 2)t/30} = 100 \cdot 2^{-t/30}$

(b) $y(100) = 100 \cdot 2^{-100/30} \approx \text{9.92 mg}$

(c)
$100 e^{- (\ln 2)t/30} = 1\ \implies\ -(\ln 2) t / 30 = \ln \frac{1}{100}\ \implies\ \\ \\
t = -30 \frac{\ln 0.01}{\ln 2} \approx \text{199.3 years}$

If (7²)x = 1 what is the vaule of x

IrinaVladis [17]

Answer:

x=4

Step-by-step explanation:

1 Add 11 to both sides.

2x=7+12x=7+1

2 Simplify 7+17+1 to 88.

2x=82x=8

3 Divide both sides by 22.

x=\frac{8}{2}x=

8

4 Simplify \frac{8}{2}

 to 44.

x=4x=4

cheek:

1 Let x=4x=4.

2\times 4-1=72×4−1=7

2 Simplify 2\times 42×4 to 88.

8-1=78−1=7

3 Simplify 8-18−1 to 77.

7=7 7=7
