Answer:
70 degrees
Step-by-step explanation:
Answer:
a)$12180.53
b)A=P(1-r)^n
Step-by-step explanation:
The formula for depreciation to use is this case is;
A=P(1-r)^n
where
A=value of boat after 5 years
P=current value of boat = $45000
r=rate of depreciation= 23% =0.23
n=time span after the boat was boat= 5 yrs
Applying the formula
A=$45000(1-0.23)^5
A=$45000(0.77)^5
A=$12180.53
You have added -13 to every function value, so every point on the graph is 13 "spaces" lower. The y-intercept is one such point, so ...
-The y-intercept is 13 spaces lower.

<em>Comment on notation</em>
In plain text an exponent is preceded by a caret (^). If the exponent has arithmetic involved (addition, subtraction, multiplication, division), then the entire exponent needs to be enclosed in parentheses. When an exponential term that has a constant base is multiplied by another constant, then some sort of multiplication indicator is useful. Your expressions might be written ...
... f(x) = 4·2^x
... f(x) = 4·2^x - 13 . . . . . . or, better, f(x) = 4(2^x) - 13 . . so it is clear -13 is not part of the exponent
Since 0.002 Is in the <u>thousandths place</u> on the right, It would be 2/1000.
So your answer would be in fratcion form:
2/1000
Word Form:
Two one-thousandths
