ANSWER

The height of the larger cone is 3cm

EXPLANATION

Since the two cones are similar we can use the scale factor to determine the height of the larger cone.

It was given that, the volume of the larger cone is 27 cm³ and the volume of the smaller cone is 8 cm³.

The scale factor for the volume is

${k}^{3} = \frac{27}{8}$

The scale factor for the length is

$k = \sqrt[3]{ \frac{27}{8} }$

$k = \frac{3}{2}$

To find the height of the larger cone, we multiply by

$h = \frac{3}{2} \times 2 = 3$

the concentration of a drug in a patient's bloodstream t hours after the drug was administrated presented by the equation c(t) =

Andrews [41]

The graph of the function has no asymptotes.

<h3>The table of values of c(t)</h3>

The function is given as:

c(t) = 5t - t² + 1

When t = 1, 2, 5, 10;

We have:

c(1) = 5(1) - 1² + 1 = 5

c(2) = 5(2) - 2² + 1 = 7

c(5) = 5(5) - 5² + 1 = 1

c(10) = 5(10) - 10² + 1 = -49

So, the table of values is

t c(t)

1 5

2 7

5 1

10 -49

See attachment for the graph of the function

<u>The domain</u>

From the question, we understand that t represents time.

Time cannot be negative i.e. t ≥ 0
The time does not exceed 5.2 i.e. t ≤ 5.2

So, the domain is 0 ≤ t ≤ 5.2

<u>The range</u>

From the graph, the maximum of the graph is 7.25

So, the range is 0 ≤ f(t) ≤ 7.25

<u>Asymptotes</u>

From the graph, we can see that the graph has no asymptotes.
