I think it’s 10 cm
Don’t know if I’m right tho

volume Large Can
r = 8 cm
pi = 3.14
h = 20 cm
V = pi r^2 h
V = 3.14*8^2 * 20
V = 4019 cm^3

Volume left over.
He has 1/4 of a can of paint left.
V1 = 1/4 * 4019
V1 = 1004.8

Calculate height.
V = 1004.8
pi = 3.14
r = 5 cm^2
h = ??

h = V/(pi r^2)
h = 1004.8 / (3.14 * 5^2)
h = 1004.8 / 78.5
h = 12.8 cm

There are other ways of doing this, but this is the clearest.

Answer:

The values of $x$ so that $y = \csc x$ have vertical asymptotes are $-2\pi$ , $-\pi$ , $0$ , $\pi$ , $2\pi$ .

Step-by-step explanation:

The function cosecant is the reciprocal of the function sine and vertical asymptotes are located at values of $x$ so that function cosecant becomes undefined, that is, when function sine is zero, whose periodicity is $\pi$ . Then, the vertical asymptotes associated with function cosecant are located in the values of $x$ of the form:

$x = 0\pm \pi\cdot i$ , $\forall \,i\in \mathbb{N}_{O}$

In other words, the values of $x$ so that $y = \csc x$ have vertical asymptotes are $-2\pi$ , $-\pi$ , $0$ , $\pi$ , $2\pi$ .

HURRYYYYYY !! A cube has an edge length of 9 centimeters.

CaHeK987 [17]

The perimiter is 4 times 1 side
currently, it is 9 times 4 or 36

increased by 3
I think y mean times 3
so 9*3=27
new perimiter is 27*4=108

how much larger is it?
108-36=72

it is 72cm larger

it is the first answer
(it isn't cm² because that is for area and we are calculating perimiter)

An equation is formed of two equal expressions. The equation of function g(x) in terms of f(x) is g(x) = -3[f(x)].

<h3>What is an equation?</h3>

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The given graph is the graph of an exponential function, the general equation of an exponential function is given by the y=aeᵇˣ. To get the function f(x) and g(x), you need to substitute the points in the given function and produce the equation of each function.

The equation for f(x) from the given graph can be written as,

$f(x)=e^{(\ln2)x}-2$
