<span>Because Sal paid for the purchase in full at the time he bought the car stereo, his total at the time was $442.00. Jen bought the same identical car stereo and her payments of $21.30 a month for 18 months equaled $383.40. Add to this total $58.60 in interest and the final total would be $442.00.</span>
Answer: No
The order of variables does not matter when combining like terms in algebra, because of the commutative property.
Explanation:
Consider the addition of two algebraic expressions.
f(x) = x³ - 5x² + 3x - 2
g(x) = 6x³ + 10x² - 7x + 9
Add f(x) and g(x).
f(x) + g(x) = x³ - 5x² + 3x - 2 + (6x³ + 10x² - 7x + 9)
= x³ + 6x³ - 5x² + 10x² + 3x - 7x - 2 + 9
= 7x³ + 5x² - 4x + 7
Now add g(x) and f(x) in order to change the order of variable addition.
g(x) + f(x) = 6x³ + 10x² - 7x + 9 + (x³ - 5x² + 3x - 2)
= 6x³ + x³ + 10x² - 5x² - 7x + 3x + 9 - 2
= 7x³ + 5x² - 4x + 7
The two additions yield the same result, although the order of variable was reversed during the addition.
In general, algebraic operations are commutative.
Answer:
interest rate is 2.25 %
Explanation:
given data
sell bond = $715
bond matures = 15 years
redeem = $1,000
solution
we apply here formula that is
amount = principal × 
................1
here put value and we get
1000 = 715 × (1+r)^{15}
= 
solve it we get
r = 0.022617
so rate is 2.25 %
Answer:
c) Adding additional project resources to the project
Explanation:
Falling behind schedule is something that needs to be avoided or dealt with promptly and systematically
Crashing is the technique to use when fast tracking has not saved enough time on the project schedule. You use crashing to save resources to the project for the least cost possible. Anyhow, crashing is expensive because more resources are added to the project.
