Answer:
downwards
Step-by-step explanation:
the equation of a parabola in vertex form is
f(x) = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
• if a > 0 then parabola opens upwards
• if a < 0 then parabola opens downwards
for
f(x) = - 4(x - 3)² + 9 with a = - 4 < 0 , then
the parabola opens downwards
Answer:
x=15
Step-by-step explanation:
2x=15+x
2x-x=15
x=15
Answer:
Measure of CIO = 30°
Measure of MAP = 150°
Complement of smaller angle = 60°
Step-by-step explanation:
Given that <CIO and <MAP are supplementary, therefore:
m<CIO + m<MAP = 180°
Let x be m<CIO
m<MAP = 5x
Thus:
x + 5x = 180
Solve for x
6x = 180
Divide both sides by 6
x = 30°
The smaller angle = m<CIO = x = 30°
The bigger angle = m<MAP) = 5x = 5(30) = 150°
Complement of the smaller angle = 90 - 30 = 60°
