Two sides of a triangle measure 6 cm and 8 cm. What is the possible measurement of the 3rd side of the triangle

Novosadov [1.4K]

Step-by-step explanation:

If the triangle is right, we can use Pitagora

We can have 2 results

$\sqrt{ {6}^{2} + {8}^{2} } = \\ = \sqrt{36 + 64} = \\ = \sqrt{100} \\ = 10$

$\sqrt{ {8}^{2} - {6}^{2} } = \\ = \sqrt{64 - 36} = \\ = \sqrt{28 } \\ = 2 \sqrt{7}$

What is the value of "?" if the Perimeter = 50 km?

777dan777 [17]

Answer:

14km

Explanation

11km + 11km = 22km is the sum of both the width.

If you want to find the length than minus the perimeter with 22.

50km - 22km = 28km is the sum of both the length.

To know only one side of the length, divide it by 2.

28km/2 = 14km is the length

The sequence defines a function $f(x)=4.(3)^{x-1}$

Domain : $\{1,2,3,4,5\}$

Range : $\{4,12,36,108,324\}$

Explanation:

A sequence defines a function if it is the set of natural numbers.

Thus, the function is given by

$f(x)=4.(3)^{x-1}$

The sequence can be determined by substituting the values for x.

For $x=1$ ,

$f(1)=4(3)^{0}=4$

For $x=2$ ,

$f(2)=4(3)^{1}=4(3)=12$

For $x=3$ ,

$f(3)=4(3)^{2}=4(9)=36$

For $x=4$ ,

$f(4)=4(3)^{3}=4(27)=108$

For $x=5$ ,

$f(5)=4(3)^{4}=4(81)=324$

Thus, from these the domain and range of a function can be determined.

The domain of a function is the set of independent values, which are generally the x-coordinates.

Domain of a function is $\{1,2,3,4,5\}$

The range of a function is the set of dependent values obtained by substituting the values for x.

Range of a function is $\{4,12,36,108,324\}$
