Answer:
-4/9
Step-by-step explanation:
We first calculate the first bracket.
[2/3-(-4/9)]
= (2/3+4/9) (we cancel out the negatives)
= (6/9+4/9) (common denominator)
= 10/9
Then we convert -2 1/2 into an improper fraction.
-2 1/2
= -5/2
Finally we calculate the division by swapping the numerator and denominator of -5/2.
10/9 / -5/2
= 10/9 * -2/5
= -20/45
= -4/9 (simplify the terms)
The expression simplifies to x/y, so the answer is no, it is not a polynomial. The fact that a variable is in the denominator means it's not a polynomial.
It could mean
1. simple interest
2. compound interest
1.simple interest
so just 8% of that 700 is added on
find 8% of 700
8% of 700=0.08 times 700=0.56
6 years=0.56 times 6=3.36
add
3.36+700=703.36
2. compound interst
that means the each year, it gives you 8% on that new thing
so
8%=0.08
so each year, it is multiplied by 1.08 since you add the original (1) to the 8% 0.08
so
6 years means
700 times 1.08^6=700 times 1.08 times 1.08 times 1.08 times 1.08 times 1.08 times 1.08=1110.81
answers are
if simple interest=$703.36
if compound interst=$1110.81
The common ratio of the consecutive numbers is obtain by dividing the second term by the first term. From the given, that is
r = 1.2 / 1.5 = 0.8
Thus, the common ratio of the consecutive terms of the given sequence is 0.8.

Answer:
C
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 32² = 48²
x² + 1024 = 2304 ( subtract 1024 from both sides )
x² = 1280 ( take the square root of both sides )
x =
