Answer:

  54°, 90°, 108°, 126°, 162°

Step-by-step explanation:

The sum of angles in a pentagon is 180°(5 -2) = 540°.

The sum of ratio units is 3 +5 +6 +7 +9 = 30. So, each "ratio unit" stands for ...

  540°/30 = 18°

Then the angles are found by multiplying the given ratios by 18°:

  3 : 5 : 6 : 7 : 9 = 54° : 90° : 108° : 126° : 162°

The functions f(x) = (x + 1)2 − 2 and g(x) = −(x − 2)2 + 1 have been rewritten using the completing-the-square method. Apply you
galina1969 [7]

Answer:

f(x)=(x+1)^2-2 is the minimum and g(x)=-(x-2)^2+1 is the maximum

Step-by-step explanation:

Looking at the graph, (you should be able to graph this) the parabola for f(x)=(x+1)^2-2 is pointing downwards and stops at the vertex. This vertex is negative which is the lowest point possible which makes it the minimum. The parabola for -(x-2)^2+1 is pointing upwards and stops at the vertex which is the highest point possible which makes it the maximum.
