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
Detailed Answer:
Diameter = Radius * 2
Radius = Diameter/2
a) 64cm
r = 32 cm
Diameter = 32 * 2 = 64cm
b) 25.2 m
r = 12.6 m
Diameter = 12.6 * 2 = 25.2 m
c) 29.5 in
r = 14 3/4 = 14.75
Diameter = 14.75 * 2 = 29.5 in
d) 64 cm
r = √32 cm^2 = 32 cm
Diameter = 32 * 2 = 64 cm
e) 49.32 ft
r = 24.66 ft
Diameter = 24.66 * 2 = 49.32 ft
Answer:
Seventy-five percent of the data values lie between 20 and 50.
Hope this helps
Sorry if I am wrong but I saw the answer in the internet
If correct can I get brainliest please
Answer:
company a
Step-by-step explanation:
It is probably company a because if you make a box and whisker plot in your head the median of 6 would be more in between 3 and 10 than 9. If the median were 9 it would probably be skewed. If 6 is near the middle the box and whisker plot would look more symmetric
