15. 10 cm, 10 cm, V200 cm : Right Angled Triangle
16. 9 in., 16 in., 25 in. : Not a right angled triangle
Step-by-step explanation:
In order to check whether the given sides form a right angled triangle, we check if the sum of squares of two shorter sides is equal to the square of third longest side.
So
<u>15. 10 cm, 10 cm, V200 cm</u>
<u>The triangle is a right angled triangle.</u>
<u>16. 9 in., 16 in., 25 in.</u>
Here
a = 9 in
b=16 in
c=25 in
So,
<u>The given triangle is not a right angled triangle.</u>

Question:
Consider the sequence of numbers: 
Which statement is a description of the sequence?
(A) The sequence is recursive, where each term is 1/4 greater than its preceding term.
(B) The sequence is recursive and can be represented by the function
f(n + 1) = f(n) + 3/8 .
(C) The sequence is arithmetic, where each pair of terms has a constant difference of 3/4 .
(D) The sequence is arithmetic and can be represented by the function
f(n + 1) = f(n)3/8.
Answer:
Option B:
The sequence is recursive and can be represented by the function
Explanation:
A sequence of numbers are
Let us first change mixed fraction into improper fraction.
To find the pattern of the sequence.
To find the common difference between the sequence of numbers.
Therefore, the common difference of the sequence is 3.
That means each term is obtained by adding 
to the previous term.
Hence, the sequence is recursive and can be represented by the function
Answer:
Step-by-step explanation:
(x-3)² - 7 = (5-3)²-7
= 2²-7
= 4 - 7
= -3
