A quantity with an initial value of 600 decays exponentially at a rate of
Snowcat [4.5K]

Answer:

The value of the quantity after 87 months will be of 599.64.

Step-by-step explanation:

A quantity with an initial value of 600 decays exponentially at a rate of 0.05% every 6 years.

This means that the quantity, after t periods of 6 years, is given by:

Q(t) = 600(1 - 0.0005)^{t}

What is the value of the quantity after 87 months, to the nearest hundredth?

6 years = 6*12 = 72 months

So 87 months is 87/72 = 1.2083 periods of 6 years. So we have to find Q(1.2083).

Q(t) = 600(1 - 0.0005)^{t}

Q(1.2083) = 600(1 - 0.0005)^{1.2083} = 599.64

The value of the quantity after 87 months will be of 599.64.

Determine the value of base b if (152)b = 0x6A. Please show all steps.
DaniilM [7]

Assuming 0x6A is given in base 16, first convert 152_b and 6A_{16} to a common base, say base 10:

152_b=1\cdot b^2+5\cdot b^1+2\cdot b^0=(b^2+5b+2)_{10}

6A_{16}=6\cdot16^1+10\cdot16^0=106_{10}

Then

b^2+5b+2=106

b^2+5b-104=(b-13)(b+8)=0

\implies b=13
