Which of the following is equivalent to sin theta csc(–theta) wherever sin theta csc(–theta) is defined?

Firlakuza [10]

$sin\theta csc(-\theta)=sin\theta\cdot\frac{1}{sin(-\theta)}=sin\theta\cdot\frac{1}{-sin\theta}=\frac{1}{-1}=-1\\\\Answer:F$

a rectangular room is 7 feet wide. it is twice as long as it is wide. what is the perimeter of the room?

Fiesta28 [93]

42 because it is all of the sides have to be added up for the perimeter so the formula would be 14+14+7+7.

bryan brought 8/10 gallon of water on a hiking trip.he drank 4/10 gallon of water.how much water is left

Lostsunrise [7]

The amount of water left is 4/10 gallons

<h3>Difference of fractions</h3>

Fractions are written as a ratio of two integers

Given the following parameters

Amount of gallon bought = 8/10 gallons

Amount he drank = 4/10

Determine the amount left

Amount left = 8/10 -4/10

Amount left = 4/10 gallons

Hence the amount of water left is 4/10 gallons

The coordinate plane below represents a city.

alex41 [277]

Answer:

Part A) The system of inequalities is

$x\geq2$ and $y\geq2$

Part B) In the procedure

Part C) The schools that Natalie is allowed to attend are A,B and D

Step-by-step explanation:

Part A: Using the graph above, create a system of inequalities that only contain points C and F in the overlapping shaded regions

we have

Points C(2,2), F(3,4)

The system of inequalities could be

$x\geq2$ -----> inequality A

The solution of the inequality A is the shaded area at the right of the solid line x=2

$y\geq2$ -----> inequality B

The solution of the inequality B is the shaded area above of the solid line y=2

see the attached figure N 1

Part B: Explain how to verify that the points C and F are solutions to the system of inequalities created in Part A

we know that

If a ordered pair is a solution of the system of inequalities, then the ordered pair must satisfy both inequalities

Verify point C

C(2,2)

<em>Inequality A</em>

$x\geq2$ -----> $2\geq2$ ----> is true

<em>Inequality B</em>

$y\geq2$ ------> $2\geq2$ ----> is true

therefore

Point C is a solution of the system of inequalities

Verify point D

F(3,4)

Inequality A

$x\geq2$ -----> $3\geq2$ ----> is true

Inequality B

$y\geq2$ ------> $4\geq2$ ----> is true

therefore

Point D is a solution of the system of inequalities

Part C: Natalie can only attend a school in her designated zone. Natalie's zone is defined by y < −2x + 2. Explain how you can identify the schools that Natalie is allowed to attend.

we have

$y < -2x+2$

The solution of the inequality is the shaded area below the dotted line $y=-2x+2$

The y-intercept of the dotted line is the point (0,2)

The x-intercept of the dotted line is the point (1,0)

To graph the inequality, plot the intercepts and shade the area below the dotted line

see the attached figure N 2

therefore

The schools that Natalie is allowed to attend are A,B and D
