It is asking for the tangent ratio at B.
In my answer; angle=theta
tan(theta)=opposite/adjacent
tan(theta)= 3/2
Answer:
Y = 300 + 2X
Y( in dollars)
It is a functional relationship because a change in the value of X results in a corresponding change in the value of Y. And does not involve any uncertainty.
Step-by-step explanation:
Given:
Annual fixed due = $300
Variable cost = $2 per visit
X = number of visits in a year
Y = total yearly cost.
Y = annual cost + variable cost
Y = $300 + $2×X
Y = 300 + 2X
Y( in dollars)
It is a functional relationship because a change in the value of X results in a corresponding change in the value of Y. And does not involve any uncertainty.
Answer: 4h/5
Step-by-step explanation:
Answer:
x-17.5
Step-by-step explanation:
angles in a triangle add to 180
3x+8+(2x-3)+5x = 180
simplify(collect like terms):
10x + 5 = 180
solve:
10x = 175
x=17.5
