Step-by-step explanation:

the correct formula for this is the heron's formula

which states that s=√s(s-a)(s-b)(s-c). Where s is a+b+c all divided by 2

s=√(13.5-12)(13.5-9)(13.5-6)

s=√(1.5)(4.5)(7.5)

s=√50.625

s= 7.11 or 7 to the nearest square unit

Suppose that you follow a population over time. When you plot your data on a semilog plot (using logs with base 10), a straight
antoniya [11.8K]

Answer:

P(t)=80(10^{0.1t})

Step-by-step explanation:

The 'y' axis represent log(P), so it may be modeled as a line (or linear function), where its slope is 0.1:

log(P)=0.1t+C

Pow each part of the equation by 10:

10^{log(P)}=10^{0.1t+C}\\ P=10^{0.1t+C}

Evaluate at t=0, where the population is known.

P(0)=10^{C}=80

Applying logarithmic properties:

P=10^{0.1t+C}=10^{0.1t}*10^{C}

So, the final function is:

P(t)=80(10^{0.1t})
