The position of the fly is shown as cross in the diagram below
The distance of the fly from the ceiling is given as
We need to work out the distance
to be able to work out the value of
by the Pythagoras theorem
by Pythagoras theorem
The distance of the fly from the point P is 4m
Answer:
Step-by-step explanation:
the answer is C
Answer:
ez the domain his the first number and the range is the second. so the domain here is 0,5,1 do not write two same numbers like 0 and 0 and the range is 5,2,-4 and again do not write 5 twice
Step-by-step explanation:
0,5,1 is the domain i could be wrong lol
Answer:
C.
f(x) = 8*(x - 1)²
f(x) = 8x² - 16x + 8
Step-by-step explanation:
vertex form:
f(x) = a*(x - h)² + k
where (h, k) is the vertex of the parabola
In this case, the vertex of the parabola is at (1, 0). Replacing this information into the equation we get:
f(x) = a*(x - 1)²
The parabola passes through point (2, 8). Replacing this information into the previous equation we get:
8 = a*(2 - 1)²
8 = a
Then, the final equation is:
f(x) = 8*(x - 1)²
Expanding the quadratic term and applying distributive property:
f(x) = 8*(x² - 2x + 1)
f(x) = 8x² - 16x + 8
