Answer:
Recursive
Explicit
Step-by-step explanation:
An arithmetic sequence an be represented by a recursive rule which gives the first term and defines the nth term by relating it to the previous term, or by an explicit rule which defines the nth term as a function of n.
The recursive rule is that we have the initial term. To find the subsequent term, we will take that <em>previous term</em> and add it to our common difference.
Hence, we are <em>relating the previous terms</em> to define the nth term.
For the explicit rule, we simply have a function of n. To find the nth term, we can substitute our desired term n for n and evaluate.
We are asked to evaluate the given expression 3 (r² + t) - r² given that r is equivalent to 2 and t is equivalent to 7. The solution to this problem is shown below:
3 (r² + t) - r² , substitute r=2 and t=7 in the expression
3 (2² + 7) - 2² , perform squared
3 (4+7) -4, perform addition of 4 and 7
3 (11) -4, perform multiplication os 3 and 11
33 - 4, perform subtraction
29
The answer is 29.
98.75 x 0.05 = 4.9375

Answer and Explanation:
Given : Sides of right triangle 5,12 and 13.
To find : Show that the area of a right triangle of sides 5, 12 and 13 cannot be a square ?
Solution :
If 5,12 and 13 are sides of a right angle triangle then
13 is the hypotenuse as it is largest side.
then we take perpendicular as 12 and base as 5.
The area of the right angle triangle is
Here, h=12 and b=5
The area of the right angle triangle is 30 units.
30 is not a perfect square as 
There is no square pair formed.
To solve the formula for v1, we must get this variable alone on one side of the equation. To do this, we use the reverse order of operations to move the other variables to the other side of the equation.
First, we begin by multiplying both sides of the equation by t, so that we can get rid of the denominator on the right side.
a = (v1 - v0)/t
a(t) = v1 - v0
Next, we must add v0 to both sides of the equation. This will get the variable v1 completely alone on the right side of the equation, giving us our answer.
(at) + v0 = v1
We should rearrange the equation so that v1 is the left side of the equation.
v1 = at + v0 (your answer)
