Answer:
b. 5/√21
Step-by-step explanation:
The sine is positive in quadrant II, so the cosecant will be also. The sine function never has a magnitude greater than 1, so the cosecant function (the reciprocal of the sine) never has a magnitude less than 1.
The only positive number with a magnitude greater than 1 among your answer choices is 5/√21, selection B.

If you draw the triangle with hypotenuse 5 and side 2 along the x-axis, you find the Pythagorean theorem tells you the opposite side (parallel to the y-axis) has length ...
... O = √(5² -2²) = √21
Then the sine ratio is ...
... Sin = Opposite/Hypotenuse = (√21)/5
The cosecant function is the reciprocal of the sine function, so its value is ...
... csc(θ) = 1/sin(θ) = 1/((√21)/5)
... csc(θ) = 5/√21
Start at the first point which in this case is (-1,-4). then go up 3 (since thats where the next point is) and over to the right 1 (since thats where the point is lol). since the line is positive, then the answer is 3/1 or 3.
Hey there!
We simply have to do 182/2.8, and you will get the area (65m^2).
We know that the formula for area is <u>length x width</u>, and the formula for volume is<u> length x width</u> x height. In the volume formula, we can see it can also be <u>area x height</u> to get <u>volume</u>. So, we know that<em><u> area x height = volume</u></em>, right? And in this equation, we are given volume and height. If <u>V = ha</u>, with V = volume; h = height; a = area, we can divide "h" on both sides, and we get V/h = a, or volume divided by height is area. To solve for the above equation, we can plug the numbers in the formula: 182/2.8 = a, or 65 = a.
Hope this helps! Have an amazing day, and remember, you've got this!
Well, it depends on the size of the ice cub and how much heat is being added. if its smaller and it has large amounts of heat being added it will melt fast, if its small and low amounts of heat are being added it will melt slower, if its a big cubs and large amounts of heat are being added it will melt slower than the small cub at the same temp but if its getting more heat than the small cub its should melt faster, ect. but in your case id say your right and bigger surface slower melt.
