Answer:
angle BEF = 100 degrees
Step-by-step explanation:
For a regular 9-sided polygon (nonagon),
each exterior angle = 360/9=40 degrees
each interior angle = 180-40 = 140 degrees.
Referring to diagram, in the trapezoid (trapezium) BCDE, the base angles are 180-140 = 40 degrees.
Therefore angle DEB = 40 degrees
that leaves BEF = 140-40 = 100 degrees
Answer:
2/5
Step-by-step explanation:
To figure out which is larger, you must first find the common denominator.
Multiply the denominators to find a common denominator:
8 x 5 = 40
Then, cross-multiply to find the new numerators:
2 x 8 = 16 3 x 5 = 15
You now have:
2/5 = 16/40 and 3/8 = 15/40
So, 2/5 is larger!
A ) This is a quadratic function:
y = a x² + b x + c
If the starting point is ( 0, 0 ) then c = 0
b ) The function is:
y = - 0.2 x² + 3.6 x
( with coefficients to the nearest tenth )
The graph is in the attachment.
c ) The roots:
x 1 = 0,
0.2 x = 3.6
x = 3.6 : 0.2
x 2 = 18d ) This is near the target ( 17 m ) . So the pumpkin
will hit near the target.
1+3=4, 2+2=4, 3+1=4, 2+2=4
