Answer:

64.8cm = x + y

The maximum sleeve length, x, plus the maximum allowable deviation, y, is 62.2cm = x - y

Step-by-step explanation:

The minimum sleeve length is the ideal length, x, minus the maximum allowable deviation, y.

64.8cm + 62.2cm = x + y + x - y

127.0cm = 2x

63.5cm = x

There are now two equations with two unknowns so both variable can be solved for.

Add the equations together and solve for the ideal length, x.

64.8cm = 63.5cm + y

1.3cm = y

Substitute x into either of the original equations and solve for y.

Result:

x = 63.5cm

±y = ±1.3cm

Consider the graph of the function f(x) = 25

trasher [3.6K]

Considering it's horizontal asymptote, the statement describes a key feature of function g(x) = 2f(x) is given by:

Horizontal asymptote at y = 0.

<h3>What are the horizontal asymptotes of a function?</h3>

They are the limits of the function as x goes to negative and positive infinity, as long as these values are not infinity.

Researching this problem on the internet, the functions are given as follows:

$f(x) = 2^x$ .

$g(x) = 2f(x) = 2(2)^x$

The limits are given as follows:

$\lim_{x \rightarrow -\infty} g(x) = \lim_{x \rightarrow -\infty} 2(2)^x = \frac{2}{2^{\infty}} = 0$

$\lim_{x \rightarrow \infty} g(x) = \lim_{x \rightarrow \infty} 2(2)^x = 2(2)^{\infty} = \infty$

Hence, the correct statement is:

Horizontal asymptote at y = 0.

I have 15a but I need 15b and 14

Naily [24]

14. For a prism, the volume is given by
.. V = Bh . . . . . . . . where B is the area of the base, and h is the height of the prism

For a pyramid, the volume is given by
.. V = (1/3)*Bh . . . . where B is the area of the base, and h is the height of the pyramid

The volume is proportional to the area of the base. If the dimensions of the base decrease linearly to zero at the height of the geometry as they do for pyramids and cones, then the volume formula includes a factor of 1/3.

15b. The volume of a pyramid is 1/3 that of a prism with the same base area and height.
