What is the inverse of f(x)=2-2x

1 answer:

6 0

In the usual sense, it has no inverse function. Since it is not an injection (f(0)=f(2)=0), an inverse function would have to map 0 both to 0 and 2, and that’s impossible.

However, if you restrict the domain to [1,+oo> (to make it injective), and the codomain to [-1,+oo> (to make it surjective), then it has an inverse function, given by g(y)=1+sqrt(y+1).

The height and radius of a cone are each multiplied by 3. What effect does this have

Black_prince [1.1K]

The volume of the original cone is multiplied by 27

<h3>Solution:</h3>

We have been given that the height and radius of a cone are each multiplied by 3.

We need to find what effect it has on the volume of the cone.

The volume of the original cone is given as follows:

$\text {Volume of cone}=\frac{1}{3} \pi r^{2} h$

Now, the radius and height are multiplied by 3.

Therefore, the new radius is ‘3r’ and the new height is ‘3h’.

Hence the new volume is

$\text {Volume of new cone}=\frac{1}{3} \pi(3 r)^{2}(3 h)=9 \pi r^{2} h$

original volume of cone x 27 = volume of new cone

Therefore, the original volume of cone is multiplied by 27

Solve the following system of equations. Express your answer as an ordered pair in the format (a,b), with no spaces between the

Sholpan [36]

2x + 7y = 4.....multiply by 2
-4x - 3y = 14
------------------
4x + 14y = 8 (result of multiplying by 2)
-4x - 3y = 14
----------------add
11y = 22
y = 2

2x + 7y = 4
2x + 7(2) = 4
2x + 14 = 4
2x = 4 - 14
2x = - 10
x = -5

solution is : (-5,2)
