Merl is a Canadian exchange student in China, and he currently has 12,000 yuan in his bank account. If the exchange rate changes

natali 33 [55]

The value has decreased because the amount he gets in Canadian dollars has decreased for the exact same amount he has in yuan.
I.e. Before: 12000/6.64 = 1807.23 Canadian dollars
Present: 12000/6.78 = 1769.91 Canadian dollars

Volume of composite figures

ollegr [7]

Given:

The diameter of cylinder is 6 in and the height of the cylinder is 8 in.

The dimensions of the cuboid are 15 in by 9 in by 9 in.

To find:

The volume of the composite figure.

Solution:

Volume of a cuboid is:

$V_1=length\times breadth\times height$

$V_1=15\times 9\times 9$

$V_1=1215$

So, the volume of the cuboid is 1215 cubic inches.

The diameter of cylinder is 6 in. So, the radius of the cylinder is:

$\dfrac{6}{2}=3\text{ inches}$

Volume of a cylinder is:

$V_2=\pi r^2h$

Where, r is the radius and h is the height.

Substituting $r=3,h=8,\pi =3.14$ , we get

$V_2=(3.14)(3)^2(8)$

$V_2=(3.14)(9)(8)$

$V_2=226.08$

The volume of the cylinder is 226.08 cubic inches.

Now, the volume of the composite figure is:

$V=V_1+V_2$

$V=1215+226.08$

$V=1441.08$

Therefore, the volume of the composite figure is 1441.08 cubic inches.

What is the range of function gif g(x) = -2/(x) + 1

Zina [86]

The function g(x) is a rational function, and none of the options represent the range of the function g(x)

<h3>How to determine the range of the function?</h3>

The function is given as:

g(x) = -2/x + 1

The above function is undefined at point x = 0.

This is so because -2/x is undefined.

So, we have:

g(0) = -undefined + 1

g(0) = undefined

This means that the range of the function is:

(-infinity, 1) and (1, infinity)

None of the options represent the range of the function g(x)
