Answer:

A(t)=A_{0}e^{\frac{ln(\frac{1}{2})}{22}t}

Step-by-step explanation:

This half life exponential decay equation goes by the formula:

A(t)=A_{0}e^{kt}

Where

k=\frac{ln(\frac{1}{2})}{Half-Life}

Since half life is given as 22, we plug that into "Half-Life" in the formula for k and then plug in the formula for k into the exponential decay formula:

So,

k=\frac{ln(\frac{1}{2})}{Half-Life}\\k=\frac{ln(\frac{1}{2})}{22}

Now

A(t)=A_{0}e^{\frac{ln(\frac{1}{2})}{22}t}

third choice is correct.

Please help me solve for the missing angle, θ.
Marrrta [24]

sinθ = opp. / hyp.

sinθ = 11 cm / 35 cm

sinθ = 0.3142857

θ = 18.31769841°


Therefore, the missing angle is approximately 18°

X+3y=-5<br> 4x-y=6<br><br> solve by elimination please
const2013 [10]
Multiply the second equation by 3, so 4x-y=6 becomes 12x-3y=18.

x + 3y = -5
+ (12x-3y = 18)
______________
13x = 13

So x = 1

Plug x = 1 into any of these, such as 1 + 3y = -5, which becomes 3y = -6, and then y = -2.
x = 1
y = -2

Rewrite the expression with the given base. <br><br> 16^x with a base of 2.
olga55 [171]
Keeping in mind that 16 = 2*2*2*2, thus 16 = 2⁴

\bf 16^x\implies (2^4)^x\implies 2^{4\cdot x}\implies 2^{4x}
