We will make a proportion:
67 : 33 = 100 : x
67 x = 33*100
67 x= 3300
x= 3300/97= 49.2537
Round to the nearest tenth:
Answer: 49.3%.
Population are often modelled by exponential functions
The population will reach 1000000 people after 26.5 years
The population function is given as:

When the population reaches 1000000 people, we have:
P(x) = 1000000
So, the equation becomes

Divide both sides by 692600

Take logarithm of both sides

Apply logarithm to both sides

Make x the subject

Solve the logarithms of 1.444 and 1.014

Divide

The value of x, is the number of years the population reaches 1000000 people.
Hence, the population will reach 1000000 people after 26.5 years

Hope this helped. A brainliest would be very much appreciated. (I need 4 brainliest so I can level up) :)
Answer:
0
Step-by-step explanation:
To evaluate log10 1 without using a calculator
From the laws of logarithm,
Logₐ b = x
Then a^x = b
Therefore if log10 1 = x
10^x = 1
From the laws of indices (any figure raised to the power of 0 = 1)
a^0 = 1
Therefore, x = 0
log10 1 = 0
