^ means to the power of or exponent
logb(x) = y is b^y = x
Answer:
18 years ( approx )
Step-by-step explanation:
Since, if an amount is compounded daily,
Then, the final amount after t years is,
A= P(1 + r/365) 365t
Where, P is the principal amount
r is the annual rate ( in decimals ),
t is the number of years,
Given,
A = $ 800,
r = 3.9% = 0.039,
P = $ 400,
By substituting the values,
800= 400 (1 + 0.039/365)365t
t = 17.774 = 18
Hence, his balance will be $800 after approximately 18 years.
Answer:
- Yes it is a right triangle
- The side lengths satisfy the Pythagorean theorem equation
Step-by-step explanation:
We can test these numbers to see if they satisfy the Pythagorean theorem equation:
15² = 9² + 12²
225 = 81 + 144 . . . . true
Since the numbers satisy the Pythagorean theorem relation, they belong to a right triangle.
____
You can recognize that the ratio of side lengths is ...
9 : 12 : 15 = 3 : 4 : 5
Further, you can recognize that the side lengths 3, 4, 5 belong to the right triangle with the smallest integer side lengths that satisfy the Pythagorean theorem. Hence the 9 : 12 : 15 triangle is similar (by a scale factor of 3) to a right triangle, thus is a right triangle.
