Answer:
f(c) =17.12c -14.56c + 5.40(.5c) - 1.20(.5c)
Step-by-step explanation:
Profit is the difference between revenue (17.12c +5.40(.5c)) and cost(14.56c+1.20(0.5c)). That difference is expressed by the function shown above.
Based on the right angle triangle and the given parameters, cos K = 5/13
<h3>Trigonometric ratios</h3>
- sin = opposite / hypotenuse
- cos = adjacent / hypotenuse
- Tan = opposite / adjacent
Given parameters:
- Hypotenuse = 13
- Adjacent = 5
- Opposite = 12
Therefore,
cos K = adjacent / hypotenuse
cos K = 5/13

M = (y2 - y1)/(x2-x1)
= 2+5/-3-1
= 7/-4
= -7/4
Answer:
Claire borrowed $500 from her father.
Step-by-step explanation:
Interest = $90
p = ?
r = 6% or 0.06
t = 3
Simple interest formula is :

Putting values in formula we get;


p = $500
