y = x² is the parent function.
This is a parabola, with minimum turning point at (0, 0 ) and axis of symmetry the y- axis
y = x² - 5
is the graph of x² translated 5 units vertically down ( indicated by - 5 )
with minimum turning point at (0, - 5 )
Answer:
x ≈ 18.9
Step-by-step explanation:
using the cosine ratio in the right triangle
cos19° =
=
( multiply both sides by 20 )
20 × cos19° = x , then
x ≈ 18.9 ( to the nearest tenth )
-4x^2/24x^5 = -x^2/6x^5 - 4 will go into the top and bottom
-x^2/6x^5 = -1/6x^3 - subtract exponents and keep the side that had the higher exponent
