No. AB is not perpendicular to AC
Answer:
x = 5
Step-by-step explanation:
4x = 1x + 15
subtract 1x from both sides
3x = 15
divide 3 from both sides
x = 5
Answer:
no it is not 32.725 is 0.01 less than
Vertex aka max or min point is found by -b/2a in form
f(x)=ax^2+bx+c
f(x)=-1x^2+8x+20
vertex x value is -8/(2)(-1)=-8/-2=4
input back to find y value
f(4)=-(4^2)+8*4+20
f(4)=-16+32+20
f(4)=36
max (since the graph opens down) is (4,36)
axis of symmetry is the x coordinate
max is (4,36)
axis of symmetrry is x=4
