Answer:
60500
Step-by-step explanation:
The sum to n terms of an arithmetic sequence is
= [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
Here a₁ = 4 and d = 7 - 4 = 3, thus
= [ (2 × 4) + (199 × 3) ]
= 100(8 + 597)
= 100 × 605
= 60500
Answer:
APY = (1 +r/n)^n -1
Step-by-step explanation:
Each period the principal is multiplied by 1 plus the periodic rate: 1 + r/n. For n periods in a year, the effective multiplier is (1 +r/n)^n. The value after this multiplication includes the principal, so to find the interest, we need to subtract the principal. The effective rate is ...
APY = (1 +r/n)^n -1
_____
You didn't ask, but the effective rates for the accounts shown are given in the attachment. The formula bar shows the formula used, and the highlighted cell shows the highest APY.

You can check whether this is true using Pythagoras' Theorem. The Pythagorean Theorem:
a² + b² = c², where c is the hypotenuse of a right triangle.
Let's plug in the given values and check the validity of the statement.
a² + b² = c²
7² + 9² = 11²
49 + 81 = 121
130 = 121
This is false. Thus,
Answer:
False - a triangle with side lengths 7, 9, and 11 is not a right triangle.
