Here to find the diagonal, you would simply split the square diagonally into 2 triangles and use the Pythagorean theorem which is used on triangles:
a² + b² = c²
a and b are both short sides and c is the diagonal side. So since it's a square, a and b would both be 5 and you would solce for c which is the diagonal:
a² + b² = c²
5² + 5² = c²              square the 5s
25 + 25 = c²            add the 25s
50 = c²                    square root both numbers to get rid of Cs 2nd power
√50 = √c²                 
√50 = c                  you can reduce the square root if you want but √50 should be fine.
√(25 × 2) = c
√(5×5×2)
5√2 = c                  this is the reduced root

The variable z is directly proportional to x, and inversely proportional to y. When x is 6 and y is 6, z has the value 12.
dalvyx [7]

z is directly proportional to x: z = kx.

If z is directly proportional to x and inversely proportional to y, then z = Kx/y.

When x= 6 and y = 6, z is 12. Find the constant of proportionality, K:

12 = K(6/6), or K = 12

Then, in general, z = 12x/y.

What is z when x=13 and y=10? z = 12(13)/(10) = 15.6 (answer)

F(x) = 5x – 20 find f(6), f(10), and f(20)
damaskus [11]

Answer:

f(6) = 10, f(10) = 30, f(20) = 80

Step-by-step explanation:

Plug in the values into the equation and compute. 5*6 - 20 = 10, 5*10 - 20 = 30, 5*20 - 20 = 80.
