ANSWER= D
Answer:
Step-by-step explanation:
The manufacturing plant earned $80 per man-hour of labor when it opened
The plant earns an additional 5% for every additional man-hour t.
This can be modeled using the function:
where Initial Amount Earned, P=80
Rate of Increase, r=5%=0.05
Therefore, the function that models the amount earned at any time t is:
Answer:
y = +3/2x + 12
Step-by-step explanation:
get slope
get midpoint
get b
1.
(-7,8) and (-1,4)
get slope
(y₂ - y₁) / (x₂ - x₁)
slope is -2/3
perpendicular slope is the negative reciprocal :
+3/2
y=mx + b
y=+3/2x + b
get midpoint :
(x₁ + x₂)/2, (y₁ + y₂)/2
(-4,6)
get b
y=mx + b
6=+3/2(-4) + b
6= -6+ b
b = 12
y = +3/2x + 12
T = 2 and t=0
i hope this helped. if i did it wrong i apologize.
Answer:
r= 5/4
Step-by-step explanation:
3/2= 12/8
subtraction property of Equality
-2/8 from both sides
r= 10/8
simplify
r=5/4
