Say r is rational. Suppose for a second, that s is not. Then, r+s is irrational. But this contradicts the fact that b is rational.
So, if one root is rational, then the other root is also rational
Answer:
approx 15%
Step-by-step explanation:
Allison puts $250 down and following that she makes 12 monthly payments of $124.49. The sum of her payments (total cost) is thus $250 + (124.49/month)(12 months) = $1743.88
The total interest she pays is $1743.88 - ($124.49/month)(12 months), or
$250
We use the simple interest formula: i = prt, where t is the number of years, and r is the interest rate as a decimal fraction:
$250 = $1599.99*r*1.
$250
Solving this for r by division, we get r = --------------- = 0.1463, or approx 15%
$1599.99
I think 24. C and 25. A I think not sure think
the answer is B or D. I mean both doesnt really matter which one. We can see that graph fallows cubic function pattern when x < 2 and option A is saying oposite (when x > 2). Option C cannot be the answer because there is graph when x is larger than 2 and that option doesnt define function when x is larger than 2.
So, B and D
If you mean surface area, the answer is 351.68 if you meant surface area for volume and l(length) for h. if not then I hope the surface area may have helped in finding your answer.
