Answer:
-3/5
Step-by-step explanation:
Pythagorean formula :
x^2 + y^2 = r^2
(-8)^2 + (-6)^2 = r^2
64 + 36 = 100
r^2 = 100
r= 10
sin is the y coordinate over the radius :
-6/10
-3/5
Answer:
the vertex represents a maximum
Vertex is (4,7)
f(x)=-(x-4)^2+7
Step-by-step explanation:
Given the function
Equation is in the form of y=ax^2+bx+c
When 'a' is negative, then vertex is maximum
when 'a' is positive, then vertex is minimum
is negative, so the vertex represents a maximum
, factor out negative
Take out negative sign in common
