27. Find a polar equation of the conic with focus at the pole that has the given eccentricity and equation of directrix.

ololo11 [35]

The polar equation will be $r=\dfrac{4}{1+cos\theta}$

<h3> What is the polar equation?</h3>

A polar equation is any equation that expresses the relationship between r and theta, where r is the distance between the pole (origin) and a point on a curve, and theta is the counterclockwise angle formed by a point on a curve, the pole, and the positive x-axis.

From the equation, we are told that

The Eccentricity: e = 1

The Directrix is y = 4

Generally, the polar equation for e = 1 and y = + c is mathematically represented as

$r =\dfrac{e\times c}{1+ecos\theta}$

$r =\dfrac{1\times 4}{1+1\times cos\theta}$

$r=\dfrac{4}{1+cos\theta}$

Therefore the polar equation will be $r=\dfrac{4}{1+cos\theta}$

Cerra Co. expects to receive 5 million euros tomorrow as a result of selling goods to the Netherlands. Cerra estimates the stand

Jlenok [28]

Answer:

$58,075

Step-by-step explanation:

Given:

Expected amount to be received = 5 million euros

Standard deviation of daily percentage change of euros, σ = 1%

Confidence level = 95%

Expected percentage change of the euro tomorrow = 0.5 percent

let,

the current spot rate of the euro (before considering the maximum one-day loss = $1.01

Now,

The maximum one-day percentage loss

= Expected change of euro - 1.65 × σ

(here 1.65 is constant for 95% confidence)

= 0.5% - 1.65 × 1%

= -1.15% (Here negative sign depicts the loss)

Therefore,

maximum one-day loss in dollars

= maximum one-day percentage loss × Exchange rate × Amount to be received

= -1.15% × $1.01 × 5 million euros

= -0.0115 × 1.01 × 5,000,000

= -$58,075 (Here negative sign depicts the loss)

The difference between twice a number and a number that is 5 more than it is 3. Which of the following equations could be used t

saw5 [17]

Answer:

Step-by-step explanation:

Let the number = x

2x - (x + 5) = 3 Answer

Now Let's solve it.

2x - x - 5 = 3

x - 5 = 3

x = 8

Check

2*8 - (8 + 5)

16 - 13

which is exactly what the right hand sign is.

vovikov84 [41]

Answer:

384π cm³

Step-by-step explanation:

Formula for the volume of a cone is $\displaystyle \large{\frac{1}{3}\pi r^2 h}$ where:—

r is radius
h is height

Our radius is given in an attachment which is 12 cm and height is 8 cm. Substitute these values in the formula:—

$\displaystyle \large{V = \frac{1}{3}\pi (12)^2 \cdot 8}\\\displaystyle \large{V = \frac{1}{3}\pi \cdot 144 \cdot 8}\\\displaystyle \large{V = 48 \pi \cdot 8}\\\displaystyle \large{V = 384 \pi}$

__________________________________________________________

Summary

Volume (Cone)

$\displaystyle \large{V = \frac{1}{3}\pi r^2 h}$ where:—

h is height or perpendicular.

r is radius.

Value of Pi (Commonly Used)

$\displaystyle \large{\pi \approx 3.14}$
