Answer:

Option C) 16(0.5x - 0.75y + 2)

Step-by-step explanation:

16(0.5x - 0.75y + 2) = 16*0.5x - 0.75y*16 + 2 *16

                                = 8.0x - 12.0y + 32

                                =  8x - 12y + 32

Find the area under the curve y = 27/x3 from x = 1 to x = t. Evaluate the area under this curve for t = 10, t = 100, and t = 100
Darina [25.2K]

Answer:

Step-by-step explanation:

given is a function as

y=\frac{27}{x^3}

We are to find the area form x=1 to x=t

The curve from x=1 lies in the I quadratnt.

So area  above x axis is to be calculated

Area = \int\limits^t_1 {\frac{27}{x^3} } \, dx \\=\frac{-27}{2x^2} \\= \frac{-27}{2t^2}-\frac{-27}{2}\\=\frac{27}{2}(1-\frac{1}{t^2} )

a) When t =10,

area = \frac{27}{2} (1-\frac{1}{10^2} )\\= 13.365

b) t=100

area = \frac{27}{2} (1-\frac{1}{100^2} )\\= 13.49865

c) t=10000

area = \frac{27}{2} (1-\frac{1}{10000^2} )\\= 13.5

Solve the equation for x
KengaRu [80]
You can do this 2 ways, one is knowing the special right triangles called triplets. An example of a triplet would be 3-4-5 where the largest value is the hypotenuse. In this example, the other 2 sides are 3 and 4 and the missing side is the hypotenuse, so using the knowledge of triplets, we can find that the hypotenuse is 5.

algebraically, we can use the Pythagorean theorem; a^2+b^2=c^2 where a and b are the opposite and adjacent and where c is the hypotenuse. We can then substitute in the values to get : 3^2 + 4^2 = c^2. When simplified, we get 9+16=c^2. Simplify further, and get 25=c^2. Now we Square root both sides to solve for C. Finally, we get C=5. Your missing side is 5.
