Answer:
x=16
Step-by-step explanation:
Actually this is trig I believe.
cos60=8/x
x=8/cos60=16
Answer:
2n-4>1n+3
Step-by-step explanation:
So basically 2 times a number go together because it means its multiplying and the greater sign is > and then 1 is multiplying with n so its 1n and then you just add 1
Bottom answer is correct: d {0, 1, 2, 3}, r {-5, -2, 3, 4}, relation is a function
Answer:
(a) 3
Step-by-step explanation:
Calculate the slope m of the line given using the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (0,3) and (x₂, y₂ ) = (3, 2)
m =
= - 
given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= 3 → (a)
Answer:
a=2
Step-by-step explanation:
u=3b-2(2) or u=3b-4
