Find the exact value of csc 5pi/6

Answers

Answer 1

Answer:

csc 2 (csc [tex]\frac{5\pi}{6}[/tex] = csc 150 = csc 30 = csc 2)

Step-by-step explanation:

csc [tex]\frac{5\pi}{6}[/tex] is in the 2nd Quadrant where only sin, and csc are positive.

csc [tex](\frac{5\pi}{6})=csc (\pi -(\frac{5\pi}{6}))=csc(\frac{5\pi}{6})[/tex]

but csc [tex]\frac{5\pi}{6}[/tex] = [tex]\frac{1}{sin (\pi/6)} = \frac{1}{sin 30} = \frac{1}{1/2} =2[/tex]

Help

Answers

Answer:

10

Step-by-step explanation:

I simply divided 140/14 and got 10! Hope this helps :)

The 140 percentage of the number 10 is 14

Given data ,

To find the number that is 140% of another number, we can set up the equation:

140% of x = 14

So , 140 percentage of the number x = 14

To solve for x, we need to convert 140% to its decimal form, which is 1.40:

1.40 * x = 14

Now we can solve for x by dividing both sides of the equation by 1.40:

x = 14 / 1.40

Dividing 14 by 1.40 gives us:

On simplifying , we get

x = 10

Therefore , the value of x = 10

Hence , 140 percentage of 10 is equal to 14

What is the slope of (-4,6) and (2,-5)

Answers

Answer:

-11/6

Step-by-step explanation:

Slope can be found with this equation:

(y₁ - y₂) / (x₁ - x₂)

What this essentially tells us to do is to put one set of the x and y coordinates into x₁ and y₁, respectfully. Then, put the other set of x and y points as x₂ and y₂.

With this scenerio, we can substitute the given points into the formula.

(6 - (-5)) / (-4 - 2) =

(6 + 5 ) / (-6) =

11 / (-6) =

-11/6

The slope is  - 11/6

The slope is equal to y2 - y1 over x2 - x1.
The answer is -11/6

Maggie wants to buy a new energy­efficient refrigerator. Her old refrigerator uses about 1200 kWh per year,while the new one would use about 400 kWh per year. Approximately how much money would Maggie saveper year if she buys the new refrigerator?

Answers

Answer:

800 Kwh

Step-by-step explanation:

To solve this problem, we need to find the difference in energy saved and then multiply by the cost of 1kWh of electricity

How much did Maggie save?

Let's first of all calculate the the difference in energy saved

Data;

old refrigerator = 1200kWhnew refrigerator = 400kWh

[tex]1200 - 400 = 800kWh[/tex]

Maggie would've saved 800kWh in one year.

But since we were not given a standard cost of electricity, we would assume that 1kWh will cost $1.

So, to determine how much she must've saved, we simply multiply $1 by 800kWh

[tex]1 * 800 = $800[/tex]

Using our assumptions, she would've saved $800 in one year.
