Step-by-step explanation:
after you draw a unit circle you will find the answer
cosec(3pi)=1/sin(3pi)
sin3pi=sinpi=0
so cosec3pi=1/0 which is undefined.
Answer:
5 centimeters
Step-by-step explanation:
We know the equation to find volume is V = B x h, where B is the base of the prism. (It is also known as the simple V = l x w x h.)
No matter what equation you use, you will end up with V = l x w x h, since the base of a rectangular prism is length x width. So, we're going to plug in our known information to get 420 = 6 x 14 x h.
Then, we're going to multiply 6 x 14 to get 84. Now we have 420 = 84 x h. To isolate the h (in order to find what it is), we must divide both sides by 84.
420/84 = 5, so whats left of the equation is 5 = h, meaning your height is 5 centimeters.
Answer:
Step-by-step explanation:
Let's start with the equation of the volume of a cylinder:
Where:
- r is the radius of the cylinder (r=D/2=24/2=12 cm)
- h is the high of the cylinder (h = 60 cm)
We can us partial derivatives to find the differential of this volume. So we will have:
(1)
Now:
dr is a differential of the radius, so in our case it is 0.1 cm and dh, differential of the high, is 0.1*2 cm. We multiply by 2 because we need to consider the top and the bottom of the cylinder.
Now we just need to put all of this definitions in the equation (1).
I hope it helps you!
Answer: 3 pounda
Step-by-step
1 bar of soap = 4 ounce
1 pound = 16 ounces
Therefore, 12 bars = 4 x 12 = 48 ounces
1 pound = 16 ounces
Therefore 48 ounces
= 3 pounds
Let x be the base of the triangle, and
2x + 4 be the height.
One of the ways in solving for the area of a triangle is to half the product of its height (h) and base (b). Mathematically,
A = bh / 2
Substituting the expression for b and h and the given condition for the area,
<em>(x)(2x + 4) / 2 ≤ 168</em>
