Y = -sqrt(x-3)
the -sqrt reflects the graph over the x-axis. Then, the -3 within the sqrt will affect the graph horizontally, shifting it to the right 3 units. (Operations inside parentheses or under radicals do the opposite. That is, - means move right and + means move left, across the y- axis).
Answer:
73
Step-by-step explanation:
90-17=x
x=73
Y=2(x+3)^2+2
y=2(x^2+6x+9)+2
y=2x^2+12x+20
dy/dx=4x+12
The graph is decreasing when dy/dx, which is velocity, is less than zero so:
dy/dx<0 when:
4x+12<0
4x<-12
x<-3
So the graph is decreasing from x=(-oo, -3)
Answer:
= 9
Step-by-step explanation:
The given parameters are;
The point of intersection of the perpendicular bisectors of the sides , , and intersect (meet) at point G
Let D represent the point of intersection of the perpendicular bisector from G to , we have for ΔBGD and ΔCGD;
≅ by reflexive property
∠GDB = ∠GDC = 90° given that is the perpendicular bisector of
Similarly, ≅ , also given that is the perpendicular bisector of
Therefore;
ΔBGD ≅ ΔCGD by Side-Angle-Side (SAS) rule of congruency
≅ by Congruent Parts of Congruent Triangles are Congruent, (CPCTC)
= = 9 by definition of congruency
∴ = 9.
