Consider this equation. cos(θ)= -3/10 If θis an angle in quadrant II, what is the value of tan (θ)?

Alja [10]

Answer:

Step-by-step explanation:

Trigonometry ratio:

$\sf Cos \ \theta = \dfrac{Adjacent \ side}{hypotenuse}=\dfrac{-3}{10}$

We need to find the opposite side using Pythagorean theorem.

opposite side² = hypotenuse² - adjacent side²

= 10² - (-3)²

= 100 - 9

= 91

opposite side = √91

$\sf tan \ \theta = \dfrac{opposite \ side}{adjacent \ side}$

$\sf = \dfrac{\sqrt{91}}{3}$

In quadrant II, value of tan $\theta$ is negative.

$\sf tan \ \theta = -\dfrac{\sqrt{91}}{3}$

Jersey village population in 1950 was 10,173. The population increases by 8.9% every 10 years. Predict the population in 2020

Oksanka [162]

Answer:

Future Value= 18,478 people

Step-by-step explanation:

eGiving the following information:

Present value (PV)= 10,173

Growth rate (g)= 0.089 every 10 years

Number of periods (n)= 7

<u>To calculate the population in 2020, we need to use the following formula:</u>

FV= PV*(1 + g)^n

FV= 10,173*(1.089^7)

FV= 18,478 people
