Answer: 35 diagonals
Step-by-step explanation:
A decagon has (10 2) – 10 = 35 diagonals.
Area of a face = side^2
cube area = area of a face * 6
cube volume = area * side
example
side = 3
area of a face = 9
cube volume = 9 * 3 = 27
AB = √(8^2 + 6^2)
AB = √100
AB = 10
AC = √(8^2 + 15^2)
AC = √289
AC = 17
BC = 9
P= AB + AC + BC
P = 10 + 17 + 9
P = 36 units
34)
Area of ABC = 1/2 x 8 x 9
A = 36 square units
Answer:
It is indeed y = -4x
Step-by-step explanation:
We see that for every increase of 1 in the x direction, y goes down 4.
Pay attention to the scales of the x and y axes.
Slope = rise/run
we rise -4 and run 1.
so the slope is -4/1 = -4
The y-intercept is at (0,0)
So the equation is y = -4x
