1 answer:
Anna007 [38]3 years ago
5 0

Answer:

Year 2004

Step-by-step explanation:

Population of a country in year 1995 = 286

Model that expresses the growth rate of the population is,

P(t) = 286(1.009)^{t-1995}

Here, t = year

a). For P = 311 million people

   311 = 286(1.009)^{t-1995}

   \text{log}(\frac{311}{286})=\text{log}(1.009)^{t-1995}

   log(311) - log(286) = (t - 1995)log(1.009)

   2.4928 - 2.4564 = (t - 1995)(0.00389)

   \frac{0.03639}{0.00389}=t-1995

   t = 1995 + 9.4

   t = 2004

In year 2004 population of the country will be 311.

A triangle has side lengths of (8d – 3) centimeters, (6d + 2) centimeters, and
alisha [4.7K]

The perimeter of a triangle is the sum of its side lengths.

The perimeter of the triangle is: 14d + 7f +7

<u>The sides of the triangle are:</u>

Side 1 = (8d - 3) cm

Side 2 = (6d + 2) cm

Side 3 = (7f + 8) cm

The perimeter (P) is calculated as:

P = Side 1 + Side 2 + Side 3

So, we have:

P = (8d - 3) + (6d + 2) + (7f + 8)

Remove brackets

P = 8d - 3 + 6d + 2 + 7f + 8

Collect like terms

P = 8d  + 6d + 7f - 3 + 2 + 8

P = 14d + 7f +7

Hence, the perimeter of the triangle is: 14d + 7f +7
