Answer:
m = - 1/4
Step-by-step explanation:
When two line is perpendicular to each other the product of them is - 1
So let the other line be B
Gradient of B = t
Gradient of A = 4

therefore m = - 1/4
Hello from MrBillDoesMath!
Answer:
76.5 ( the last choice)
Discussion:
Sum =
1/2 ( 1! + 2! + 3! +4! +5!) =
1/2( 1 + 2+ +6 + 24 + 120) =
1/2(153) =
76.5
which is the last choice
Thank you,
MrB
