Answer:
y = 5
Step-by-step explanation:
The first term (a1) is 9, and the common difference (d) is 4. Then the general term is ...
an = a1 + (n-1)·d = 9 + 4(n -1) = 4n +5
The "y-intercept" corresponds to the value when n=0. That value is ...
a0 = 4·0 +5 = 5
The y-intercept is 5.

<em>Comment on the problem</em>
We have computed f(n) for n=0, but we must realize that n=0 is outside the domain of the function. This function only makes sense for integer values of n that are greater than zero. The "real" answer is that the y-intercept is "undefined."
Explanation
The shaded area represents a segment. This can be solved with the formula below;
Since the triangle is an equilateral triangle, it implies that the angle subtended at the centre is 60 degrees. Also, the given radius is 7 cm
Answer:
Answer:10,000
Step-by-step explanation:
10×10×10×10=10,000
The number of payments per year is 12
The number of payments is 36 which means that the term lasted for 3 years.
The total interest is $158.15 and the amount financed is $2500.
The interest rate is
158.15/2500 = 6.33%
In nominal month, that is
(1 + r/12)^12 - 1 = 0.0633
Solve for r
