Answer:
Below in bold.
Step-by-step explanation:
Nth term an = a1 + d(n - 1) where a1 = term 1 and d = common difference.
Here a1 = 5 and d = 8-5 = 3.
So an = 5 + 3(n - 1)
15th term a15
= 5 + 3(15 - 1)
= 5 + 42
= 47.
Answer:
$106
Step-by-step explanation:
The formula given for Monthly payment of a loan =
P × [ r (1 + r)/(1 + r)^n - 1
Where
r = interest rate
n = number of monthly payments
P = Present value of the loan
From the question,
r = interest rate, we were told to ignore hence, r = 0
P = $3,175
n = 30
Hence,
Amount to be paid monthly = P/n
= $3175/30
= $105.83
Approximately to the nearest dollars
= $106
Answer:
a) x = 3.0625m
y = 45.9375 m
b) A = 140.68359375 m²
Step-by-step explanation:
Let x be the length
Let y be the width
2x + 2y = 98
x + y = 49
y = 3(5x)
y = 15x
x + 15x = 49
16x = 49
x = 3.0625 m
y = 15(3.0625) = 45.9375
A = xy = 3.0625(45.9375) = 140.68359375
This seems to look like a factoring question. When factoring, one must know that the second number is the sum of the two values multiplied by x, and the third number is what happens when one multiplies those two numbers. Using these definitions, one can conclude that the correct answer is (x-8)(x+3)
