Answer:

h=9cm

P=(x+5)cm

b=(x-3)cm

by the Pythagoras theorem,

h^2=p^2+b^2

9^2=(x+5)^2+(x-3)^2

81=x^2+10x+25+x^2-6x+9

81=2x^2+4x+34

Keith_Richards [23]

Answer:

42

Step-by-step explanation:

_aP_b = \dfrac{a!}{(a - b)!}

_7P_2 = \dfrac{7!}{(7 - 2)!}

_7P_2 = \dfrac{7 \times 6 \times 5!}{5!}

_7P_2 = 7 \times 6

_7P_2 = 42

For a period of time, an island’s population grows at a rate proportional to its population. If the growth rate is 4.5% per year
Oduvanchick [21]

The population of the island with growth rate of 4.5% per year and the current population is 1500 is 1953 after 6 years.

<h3>How to solve an exponential function</h3>

Let y represent the population after x years.

Given that the growth rate is 4.5% per year and the current population is 1500.

Hence a = 1500, b = 100% + 4.5% = 104.5% = 1.045

y = 1500(1.045)ˣ

After 6 years:

y = 1500(1.045)⁶ = 1953

The population of the island with growth rate of 4.5% per year and the current population is 1500 is 1953 after 6 years.
