Answer:
USD $342.47
Step-by-step explanation:
For these kinds of questions, I like to use what I call the 'I want... If' method. I'll walk you through my thought process. Essentially, when I write my formula, I think, 'I want to find out how many US dollars I can receive from JMD $50,000 if JMD $146 is USD $1.
Essentially, the 'I want to find out... $50,000' part goes in the nominator of a fraction. 'If JMD $146' goes in the denominator of the same fraction. Then, add a multiply operator and finally 'is USD $1' goes after the operator.
In working, it looks like this:
JMD $ x USD $1 = USD $342.4657534247 = USD $342.47 (To 3 s.f.)
Answer:
Step-by-step explanation:
The coordinates of the points through which the line passes are (1, 3) and (5, 1)
The slope, m, of a line given the coordinates of two known points on the line, (x₁, y₁), (x₂, y₂) can be found as follows;
The slope of the given line is therefore
The equation of the line in point and slope form is therefore, y - y₁ = m·(x - x₁) or y - y₂ = m·(x - x₂)
Therefore, by substituting the known values, we have the equation in point and slope form as follows;
Answer:
The current deer population is 240.
Step-by-step explanation:
The expression given models a exponential decay follows:
For every year that passes since the beginning of the count the population is 0.978 of the year prior. Assuming that the count starts at this year, then "n" is equal to 0, applying this value of n to the formula gives us:
The current deer population is 240.
