If x∆y = 3x - y², then
5∆1 = 3×5 - 1² = 15 - 1 = 14
and
14∆6 = 3×14 - 6² = 42 - 36 = 6
So (5∆1)∆6 = 6.
Answer:
Step-by-step explanation:
In order to find the value of y, first we need to find the length of the perpendicular dropped from one of the vertices of the triangle to its opposite side.
By geometric mean theorem:
Length of the perpendicular
Next, by Pythagoras theorem:
What is the question if it 98-49 than it would be 49
Answer:
(-∞, ∞) = domain
(-∞, 12] = range
Explanation:
Find the domain by finding where the function is defined. The range is the set of values that correspond with the domain.
Hope this helps! :)
