The statement that correctly describes the product, 5.15 x 6√7, which is 81.7537155..., is <u>A. </u><u>irrational</u>.
<h3>What is an irrational product?</h3>
An irrational number is one that can be written as a decimal, but not as a fraction.
An irrational number has endless non-repeating digits to the right of the decimal point.
The rules for determining if a product is rational or irrational are as follows:
- The product of two rational numbers is rational.
- The product of a rational number and an irrational number is irrational.
- The product of two irrational numbers is irrational.
<h3>Data and Calculations:</h3>
5.15 x 6√7
= 5.15 x 6 x 2.64575...
= 81.7537155...
Thus, the product of 5.15 x 6√7 is irrational because √7 is irrational.

Answer:
The nth term of the given sequence
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given sequence -5,-4,-1,4,11,20,31
a₀ = -5
a₁ = a₀ +1 = -5 +1 = -4
a₂ = a₁ + 3 = -4+3 = -1
a₃ = a₂ + 5 = -1 +5 = 4
a₄ = a₃ + 7 = 4 + 7 =11
a₅ = a₄ + 9 = 11+9 = 20
a₆ = a₅ + 11 = 20+11 = 31
a₇ = a₆ + 13 = 31 +13 =44
and so on
The nth term of the given sequence
