Answer:
p(m) = 0.1(m)
Step-by-step explanation:
Given that :
Percentage of cost saved per month = 10%
The percentage, p of cost saved after m months will be ;
Percentage of cost saved after m, months will be ; p(m) = Percentage of cost saved per month * number of months
p(m) = 10% * m
p(m) = 0.1(m)
79 dollars plus its 40% times 4 equals 442.4 that plus 12% equals 495.488 rounded up to 495 dollars and 49 cents
Answer: 
Explanation:
Follow PEMDAS in reverse to undo what's happening to x.
We first add 1 to both sides, then divide both sides by 5 to fully isolate x.
Refer to the steps below to see what I mean.

The inequality sign stays the same the entire time. The only time it flips is when you divide both sides by a negative number.
The solution set for x is anything -3 or larger.
If x was an integer, then we could say the solution set is {-3, -2, -1, 0, 1, 2, 3, 4, 5, 6, ...}
Step-by-step explanation:
Let θ be the angle of depression i.e the angle between the horizontal and the observer's line of sight.
tanθ= (Height of the light house)/(Horizontal distance of ship from the base of light house)
∴tanθ=88/1532=0.0574
∴θ=tan−1(0.0574)=3.290(2dp)
