Answer:
The constant of proportionality is 6
Step-by-step explanation:
Recall the equation for direct variation is
where
varies directly with
and
is the constant of proportionality. If we take any listed coordinate point, we can determine the value of
. I will use (20,120) as an example:

Therefore, the constant of proportionality is 6
Answer:
(suprisingly easy) 6x3x4=72 in.
Step-by-step explanation:
Answer:
<h2>256</h2>
Step-by-step explanation:
The expression 4 raised to 4 can be written in mathematical term as
and this means the value of 4 in four places as shown;

Hence the expression 4 raised to 4 is equivalent to 256
Step-by-step explanation:
sec⁴A + tan⁴A = 1 + (2tan²A/cos²A)
LHS = sec⁴A + tan⁴A
= (sec²A)² + (tan²A)² {using formula of a²+b²)
= (sec²A-tan²A) + 2tan²A.sec²A
= 1 + {2tan²A.(1/cos²A)}
= 1 + (2tan²A/cos²A)
