Dexter has 83 tiles left over from tiling his bathroom floor and he would like to use them to tile the front entrance of his hou
creativ13 [48]

Answer: [0, 396]

Step-by-step explanation:

The domain is the acceptable values of x in the function.  In this case, x = t, the number of tiles.  If you think about it, the minimum number of tiles is 0 (you can't have a negative number of tiles), and the maximum number of tiles is 44 (you only have 44 tiles).  So, the domain for this function is from 0 to 44.

0 to 44 written in interval notation is [0,44].

The range is the acceptable values of y in the function.  In this case, y = A, the area given.  A(t) = 9t, so you can use the acceptable values of t to get the range.  Again, the minimum area is 0 because you can't have negative area. To find the maximum area, plug in the maximum number of tiles: 9.

A(t) = 9t

A = 9(44)

A = 396

With the maximum number of tiles, 44, the area you get is 396 cm².  Therefore, the acceptable values of A are from 0 to 396.

0 to 396 written in interval notation is [0, 396].

Which function has a simplified base of 4RootIndex 3 StartRoot 4 EndRoot? f(x) = 2(RootIndex 3 StartRoot 16 EndRoot) Superscript
PIT_PIT [208]

Answer:

  f(x)=4\sqrt[3]{16}^{2x}

Step-by-step explanation:

We believe you're wanting to find a function with an equivalent base of ...

  4\sqrt[3]{4}\approx 6.3496

The functions you're looking at seem to be ...

  f(x)=2\sqrt[3]{16}^x\approx 2\cdot2.5198^x\\\\f(x)=2\sqrt[3]{64}^x=2\cdot 4^x\\\\f(x)=4\sqrt[3]{16}^{2x}\approx 4\cdot 6.3496^x\ \leftarrow\text{ this one}\\\\f(x)=4\sqrt[3]{64}^{2x}=4\cdot 16^x

The third choice seems to be the one you're looking for.

Which statement is true when all points of a line lie in a plane?
stira [4]
Your answer would be choice 3, because when all points of a line lie in a plane, the plain contains the line so the line can contain all of the points. Hope this helped. ;)

Which equation has a constant of proportionality equal to 2?
NemiM [27]

Answer:

A

Step-by-step explanation:

The equation y=kx describes the proportional relationship between variables x and y. In this equation, k is the coefficient of proportionality.

Consider all options:

A. For the equation

y=\dfrac{10}{5}x,

the coefficient of proportionality is

k=\dfrac{10}{5}=2

B. For the equation

y=\dfrac{2}{2}x,

the coefficient of proportionality is

k=\dfrac{2}{2}=1

C. For the equation

y=\dfrac{2}{4}x,

the coefficient of proportionality is

k=\dfrac{2}{4}=\dfrac{1}{2}

D. For the equation

y=\dfrac{22}{22}x,

the coefficient of proportionality is

k=\dfrac{22}{22}=1
