Answer:
x ≈ 14.4
Step-by-step explanation:
using the cosine ratio in the right triangle
cos59° =
=
( multiply both sides by 28 )
28 × cos59° , then
x ≈ 14.4 ( to the nearest tenth )
<span>-7 x (-9) = +63
because if we multiply negative by negative we obtain +</span>
The new equation is
<em>Y = (x-8)² </em>.
The other way to write it is like this: (you might not recognize it in this form)
Y = x² - 16x + 64
5 and 6 because 5 1/4 = 5.25.
5.25 is less than 6, but greater than 5.
