Answer:
7
Step-by-step explanation:
number of diagonals in a regular polygon = number of sides - 2.
A nonagon is a polygon having 9 sides.
Total number of diagonals in a regular nonagon
= 9 - 2
= 7
This is an EXPONENT.
To do this all we need to do is multiply the base by itself how many times the power says.
(-6)² = (-6) × (-6) = 36
Recall that any negative number times another negative number is positive so that is why this would be positive.
So, (-6)² = 36

Answer:
Option (4)
Step-by-step explanation:
Vertices of the triangle are X(0, -4), Y(2, -3) and Z(2, -6).
Slope of XY (
) = 
= 
(
) = 
Similarly, slope of XZ (
) =
(
) = (-1)
Which should be (-1) if XY and XZ are perpendicular to each other.
Now we can say that XY and XZ are not perpendicular.
Therefore, Lydia's assertion that ΔXYZ is a right triangle is not correct.
Option (4) will be the answer.
Answer:
we are going to use the formula...
V=πr2h
Step-by-step explanation:
so
V = (3.14) 4x4 (9)
V = (3.14) 16 x 9
V = 3.14 x 144
V = 452.16
Hence, the third or C
