Step-by-step explanation:
y = -9x - 45 -5
y = -9x - 50
slope = x coefficient = -9
we can use the point where
x = 0
y = -50
P1 (0, -50)
and when y = 0
-9x = 50
x = -50/9
P2 = (-50/9 , 0)
Answer:
Tn = Tn-1 + 2(n-1) + 5
Kindly note that Tn-1 means T subscript n-1
Step-by-step explanation:
Here, we want an expression for the nth term.
First term is 7
Then first common difference is 7
second common difference is 7 + 2
Third common difference is 9 + 2
So within the common differences, the nth term is 7 + (n-1) 2
Now, the nth term of the series would be;
Tn = Tn-1 + 7 + 2(n-1)
Tn = Tn-1 + 7 + 2n -2
Tn = Tn-1 + 2n + 5
Now there is a fix to this,
n for the term is not the same n for the common difference.
the 7th term works with the 6th common. difference, while the 8th term work for the 7th common difference.
So we might need to rewrite the final expression as follows;
Tn = Tn-1 + 2(n-1) + 5
Answer:
You would have $343.37 at the end of the 2 years.
Step-by-step explanation:
Interest earned is like bonus money the bank pays you just for keeping money
P: the starting balance of the account (also called initial deposit, or principal)
A: the new balance in the account after N years.
t: the number of years or time
r: the interest rate, (in decimal form)
n: the number of times the interest is compounded each year.
Annually = each year = 1
P =$300, r = 7%, t = 2, n = 1, A = ?
Substitute the numbers into the "Compound Interest Formula".
So you would have $343.37 at the end of the 2 years.

Answer:
0.4
Step-by-step explanation:
Find square root of 12 and 15
12=3.46 rounded to 3.5
15=3.87 rounded to 3.9
0.9-0.5=0.4
