Find the distance traveled by the tip of the second hand of a clock in one minute if the hand is 6cm long.

gayaneshka [121]

The circumference of a circle with radius 6 inches is 12π inches. 15 minutes is 1/4 of the circle which is 60 minutes Therefore the tip moves 1/4 of 12π = 3π inches In 25 minutes the tip moves (25/60)12π = 5π inches Yes, you can also use the formula s = rθ θ is the angle of rotation. 15 minutes is equivalent to 90 degrees or π/2 radians Therefore s = 6 inches(π/2) = 3π inches 25 minutes is equivalent to 25/60 x 360 degrees = 150 degrees = 5π/6 radians

Pls help need answer asap pls provide explanation if you can if not than it is fine thx

Answer:

Correct options are B, C and E.

Step-by-step explanation:

From the graph, we see that,

A. The graph is a decreasing as the number of years are increasing.

So, the function is not representing an exponential growth.

B. From the graph, we see that,

At 0 years, the function value is at 500,000.

Thus, there was $500,000 initially when the owner started making withdrawals

C. From the graph, we see that,

At 10 years, the function value is at 300,000.

Thus, after 10 years, there is exactly $300,000 left in the account.

D. We have that, 'The amount that the owner withdraws is given by the slope of the points'.

So, the slope at different points is given by,

$\frac{300,000-500,000}{10-0}=\frac{-200,000}{10}=-200,00$

$\frac{100,000-200,000}{30-10}=\frac{-100,000}{10}=-100,00$

So, the amount withdrew each year is not same.

E. As, the y-axis represents the amount of money remaining when the owner started withdrawing.

The y-intercept is the point when the graph crosses y-axis i.e. when x = 0.

So, the y-intercept represents the amount of money withdrew at 0 years.

Thus, y-intercept represents the amount of money in the account when the owner started making withdrawals.

Hence, the correct options are B, C and E.

Find the polar equation of the conic with the focus at the pole, directrix x = -5, and eccentricity 2.

prohojiy [21]

Step-by-step explanation:

Given that,

Directrix, d= -5, and eccentricity, e = 2.

The polar equation of the conic is given by :

$r=\dfrac{ed}{1-e\cos\theta}$

Put all the values,

$r=\dfrac{-5\times 2}{1-2\cos\theta}\\\\=\dfrac{-10}{1-2\cos\theta}$

As e>1, it is a hyperbola. Hence, this is the required solution.
