Answer:

h = 22.91 cm

Step-by-step explanation:

Given that,

The volume of a vase, A = 1330.2 cm³

Radius of the vase, r = 4.3 cm

We need to find the height of the vase. The formula for the volume of a cylinder is given by :

$V=\pi r^2 h\\\\h=\dfrac{V}{\pi r^2}\\\\h=\dfrac{1330.2 }{3.14\times (4.3)^2}\\\\h=22.91\ cm$

h = 23 cm

So, the height of the vase is equal to 23 cm.

The angle of sine has a value of 3/5.

Option A is the correct representation of angle sin(b°).

<h2>How do you calculate the angle b for sine?</h2>

Given that tan(b°) = 3/4 and cos(b°) = 4/5.

In trigonometry, we know that,

$\dfrac {sin \theta}{cos \theta} = tan \theta$

The angle of sine can be written as below.

$sin \theta = cos \theta \times tan \theta$

For the angle b, the above expression can be written as,

$sin (b^\circ) = cos (b^\circ) \times tan (b^\circ)$

Substituting the values in the above expression, we get,

$sin (b^\circ) = \dfrac {3}{4} \times \dfrac {4}{5}$

$sin (b^\circ) = \dfrac {3}{5}$

Hence we can conclude that the angle of sine has a value of 3/5.

Answer:

The question confused me a bit because of the different numbers.

The answer would be

w(2 * 18), which would be the same as choice a if the numbers weren't different.

Consider the function f(x) = x(x-4.

jeyben [28]

Step-by-step explanation:

point (c-2, y) lies on the graph of f(x)=x(x-4)f(x)=x(x−4) .

Step-by-step explanation:

Given function f(x)=x(x-4)f(x)=x(x−4) also point (2+ c,y) is on the graph of f(x) ,

We have to find out of given point which point will also be on the graph of f(x).

Consider the given function f(x)=x(x-4)f(x)=x(x−4)

f(x)=x(x-4)f(x)=x(x−4) can be rewritten f(x)=x^2-4xf(x)=x

−4x

Now we substitute the given point (2+ c, y) in the function given ,

we have,

f(x)=y=x(x-4)f(x)=y=x(x−4)

put for x as 2+c , we have,

\Rightarrow y=(2+c)(2+c-4)⇒y=(2+c)(2+c−4)

Solve, we get

\Rightarrow y=(2+c)(c-2)⇒y=(2+c)(c−2)

Thus, both point (2+c, y) and (c-2, y) lies on the graph of f(x)=x(x-4)f(x)=x(x−4)

Thus, option (1) is correct.
