What is the domain of the relation y = arccscx?
Stella [2.4K]

Answer:

y=arc\csc x

Step-by-step explanation:

The given function is y=arc\csc x.

The domain refers to all values of x for which this function is defined.

Recall that: the domain of y=arc \sin (x) is -1\le x\le1

And we know y=arc\csc x is the reciprocal of y=arc \sin (x).

Therefore the complement of the domain of y=arc \sin (x) which is (-\infty,-1]\cup [1,+\infty) is the domain of y=arc\csc x

What is the x coordinate of the solution of the system? 2x+y=15 and x-y=3
Varvara68 [4.7K]

x - y = 3

x = 3 + y

x -3 = y

y = x-3

put it in 1st equation

2x +y = 15

2x + x - 3 = 15

3x - 3 = 15

3x = 15+3 = 18

x = 18/3 = 6

x = 6

Tema [17]

Answer:

592 hours

Step-by-step explanation:

Given

Area = 11000m^2

Radius = 0.10m/h

Required

Determine the time taken to cover the area

Since, the oil formed a circular pattern; the question will be answered using area of a circle

Area = \pi r^2

Let t represent the time take to cover 11000m²;

The relationship between these parameters is:

11000 = \pi * (0.10t)^2

Substitute 3.14 for π

11000 = 3.14 * (0.10t)^2

Divide both sides by 3.14

\frac{11000}{3.14} = \frac{3.14 * (0.10t)^2}{3.14}

\frac{11000}{3.14} =(0.10t)^2

3503.18471338 = (0.10t)^2

Take square root of both sides

\sqrt{3503.18471338} = \sqrt{(0.10t)^2}

\sqrt{3503.18471338} = 0.10t

59.1877074516 = 0.10t

Divide both sides by 0.10

\frac{59.1877074516}{0.10} = \frac{0.10t}{0.10}

\frac{59.1877074516}{0.10} = t

591.877074516 = t

t = 591.877074516

t = 592\ hours <em>(</em><em>Approximated)</em>

<em>Hence, it'll take approximately 592 hours to cover the given area</em>
