The 6 term of a G.P is -2\27 and it's first term is 18.what is the common ratio​
Airida [17]

Answer:

r = - \frac{1}{3}

Step-by-step explanation:

The n th term of a GP is

a_{n} = a₁ r^{n-1}

where a₁ is the first term and r the common ratio

Here a₁ = 18 and a₆ = - \frac{2}{27} , then

18 r^{5} = - \frac{2}{27} ( divide both sides by 18 )

r^{5} = - \frac{1}{243} ( take the fifth root of both sides )

r = \sqrt[5]{-\frac{1}{243} } = - \frac{1}{3}

A weather forecaster says the temperature will be about-5C “give or take” 10 degrees. What is the greatest possible temperature?
IRINA_888 [86]

The greatest possible temperature is 5^{\circ} \mathrm{C} and least possible temperature is -15^{\circ} \mathrm{C}

<u>Solution:</u>

Given that according to weather forecaster the temperature will be about -5 degree celsius given or take 10 degree”

Need to determine greatest possible temperature and least possible temperature.

Give and take in given statement means a temperature can go up by 10 degrees and can go down by 10 degrees

So greatest possible temperature will be -5^{\circ} \mathrm{C}+10^{\circ} \mathrm{C}=5^{\circ} \mathrm{C}

Least possible temperature will be -5^{\circ} \mathrm{C}-10^{\circ} \mathrm{C}=-15^{\circ} \mathrm{C}

Hence according to weather forecaster, greatest possible temperature = 5^{\circ} \mathrm{C} and least possible temperature = -15^{\circ} \mathrm{C}
