Answer:
25.6
Step-by-step explanation:
Add 6.4 to all the sides and add them all together-
6.4+6.4+6.4+6.4 = 25.6
I'm going to use n instead of t
rⁿ=6.25rⁿ+2
minus rⁿ both sides
0=5.25rⁿ+2
minus 2 both sides
-2=5.25rⁿ
divide both sides by 5.25
-2/5.25=rⁿ
take the nth root of both sides
![\sqrt[n]{\frac{-2}{5.25}}= \sqrt[n]{r^n}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7B%5Cfrac%7B-2%7D%7B5.25%7D%7D%3D%20%5Csqrt%5Bn%5D%7Br%5En%7D)
![\sqrt[n]{\frac{-2}{5.25}}= r](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7B%5Cfrac%7B-2%7D%7B5.25%7D%7D%3D%20r)
20 possibilities based on this as a combination not a permutation, 6 nCr 3 = 20
The statement "The whole number has one digit if and only if the whole number is less than 10" is true for converse statement. Then the correct option is C.
<h3>What are converse statements?</h3>
A inverse statement is one that is derived by opposing the supposition and result of a relative clause.
Let p: The whole number has one digit.
Let q: The whole number is less than 10.
The statement "The whole number has one digit if and only if the whole number is less than 10" is true for converse statement.
If p → q, then, q → p
Then the correct option is C.
