Answer:
vertex =
(
4 , 25
)
Step-by-step explanation:
given a parabola in standard form y
= a
x
2
+
b
x
+
c
x
;
a
≠
0
then the x-coordinate of the vertex is
X vertex=-b/2a
y=-x2+8x+9 with a=-1 b=8 c=9
X vertex= -8/-2=4
substitute the value on the equation
Y vertex = -(4)squared+8(4)+9=25
Isolate the variable by dividing each side by factors that don't contain the variable.
x=40

Answer:
yes they are.
Step-by-step explanation:
if you were to divide the numbers in the first triangle by 2.5 you would get the numbers of the other triangles and vice versa for the other triangle
There are 100 centimeters in one meter
therefore .1 meters = 10 centimeters
.01 meters = 1 centimeter
to convert form centimeters to meters you will move the decimal to the left 2 times starting from the far most right digit.
