Answer:
The missing dimension is

Step-by-step explanation:
The Pythagorean Theorem states that

Note that c is the hypothenus <em>(</em><em>the</em><em> </em><em>hypothenus</em><em> </em><em>is</em><em> </em><em>always</em><em> </em><em>opposite</em><em> </em><em>to</em><em> </em><em>the</em><em> </em><em>right</em><em> </em><em>angle</em><em> </em><em>of</em><em> </em><em>a</em><em> </em><em>triangle</em><em>)</em>
Therefore


Therefore the missing dimension is 5

Step-by-step explanation:
Go to Khan Academy and type in Solving linear systems the matrices (video).
Answer:
y = 36
Step-by-step explanation:
Given y varies directly as z and inversely as x then the equation relating them is
y =
← k is the constant of variation
To find k use the condition y = - 18, z = 3 when x = 6 , then
- 18 =
( multiply both sides by 6 )
- 108 = 3k ( divide both sides by 3 )
- 36 = k
y =
← equation of variation
When x = 5 and z = - 5, then
y =
=
= 36
Answer:


Step-by-step explanation:
Given
Grade 9: 22
Grade 10: 32
Grade 11: 41
Grade 12: 30
Required
Determine the domain and the range
The domain and range of a function is represented as thus (x,y)
From the given parameters;

Remove "Grade" to represent as only digits

Split to x and y values:
<em>Where x = domain and y = range</em>


<em>So, from the list of given options; option C answers the question.</em>
