Find the missing dimension of the prism. Round your answer to the nearest hundredth.
Nitella [24]

Answer:

x = 6.99in

Step-by-step explanation:

Given

l =2in

Volume = 72.66in^3

See attachment for prism

Required

Find x

The prism has a regular hexagon base

The base area is calculated as:

Base\ Area= \frac{3\sqrt 3}{2}l^2

This gives:

Base\ Area= \frac{3\sqrt 3}{2} * 2^2

Base\ Area= \frac{3\sqrt 3}{2} * 4

Base\ Area= 3\sqrt 3 * 2

Base\ Area= 6\sqrt 3

Side x represents the height.

So, we have:

Volume = Base\ Area*x

Make x the subject

x = \frac{Volume }{ Base\ Area}

x = \frac{72.66in^3}{6\sqrt 3 in^2}

x = \frac{72.66}{6\sqrt 3}in

x = \frac{12.11}{\sqrt 3}in

x = 6.99in --- approximated

K anyone help please
tigry1 [53]

Answer:

Step-by-step explanation:

Given equation is,

a). y = \frac{6}{x}

x        0.5                1            2            3            4              5             6

y       \frac{6}{0.5}=12      \frac{6}{1}=6      \frac{6}{2}=3      \frac{6}{3}=2     \frac{6}{4}=1.5     \frac{6}{5}=1.2     \frac{6}{6}=1

b). By plotting the input-output values on the graph we get the curve as shown in option C.

Therefore, Option C will be the answer.
