Answer:
A
Step-by-step explanation:
Calculate the midpoint using the midpoint formula
[ 0.5(x₁ + x₂ ), 0.5(y₁ + y₂ ) ]
with (x₁, y₁ ) = (- 1, 5) and (x₂, y₂ ) = (5, 5)
midpoint = [ 0.5(- 1 + 5), 0.5(5 + 5) ]
= [ 0.5(4), 0.5(10) ] = (2, 5 ) → A
Answer:
The length of the sides are 8 , 32 , 36
Step-by-step explanation:
Ratio of sides = 2 : 8 : 9
The sides are 2x , 8x , 9x
Perimeter of triangle = 76 inches
2x+ 8x + 9x = 76
19x = 76
x = 76/19
x = 4
2x = 2*4 = 8
8x = 8 * 4 = 32
9x = 9 * 4 = 36

Answer:
F/m=a
Step-by-step explanation:
Answer:
f(n) = 6n + 12
Step-by-step explanation:
There is a common difference in consecutive number of seats, that is
42 - 36 = 36 - 30 = 30 - 24 = 24 - 18 = 6
This indicates the sequence is arithmetic with nth term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 18 and d = 6 , then
f(n) = 18 + 6(n - 1) = 18 + 6n - 6 = 6n + 12
