-20 28/35, -20, 20 28/40, 20 27/30

- the negative numbers will always be less than the positive numbers, so those will be first. Now you have to find the BIGGEST negative number, that’s is worth less than the smaller negative number, because negatives are like opposites of positives. So the bigger negative number is first, then the next negative number. Now you just find the smallest positive number to the biggest positive number.

What is the value of x2+9x+20 when x could be -5, -3 or -6
ANTONII [103]

Answer:

Step-by-step explanation:

You should use a ^ to indicate an exponent. x^2 is the same as x².

x² + 9x + 20

Replace the x with (-5).

(-5)² + 9(-5) + 20 = 25-45+20 = 0

Then do the same with x = (-3):

(-3)² + 9(-3) + 20 = 9 - 27 + 20 = 2

You can do x = (-6)

Alice and her friend Emma leave on different flights from the same airport. Alice's flight flies 100 miles due south, then turns
DaniilM [7]

9514 1404 393

Answer:

  Emma's flight is farther from the airport

Step-by-step explanation:

Even without doing any detailed calculation, you can see on a graph that the larger turn Alice's flight makes keeps it closer to the airport.

Emma's flight is farther from the airport.

__

The distance can be calculated using the Law of Cosines. The angle of interest is the supplement of the turn angle. Since the leg distances are the same in each case, the only variable affecting the distance from the airport is the angle measure. Again, the larger the turn, the shorter the distance from the airport. If T is the turn angle, the distance is ...

  d² = 100² +50² -2·100·50·cos(180° -T)

  d² = 12500 +10000·cos(T) . . . . . . . using cos(180°-T) = -cos(T)

  d = 100√(1.25+cos(T))

For Alice's 70° turn, the distance is ...

  d = 100√(1.25+0.342) ≈ 126.18 mi

For Emma's 50° turn, the distance is ...

  d = 100√(1.25 +0.643) ≈ 137.58 mi

Emma's flight is farther from the airport.

_____

The law of cosines formula is ...

  c² = a² +b² -2ab·cos(C)

where triangle sides are lengths a, b, c and angle C is opposite side c.

-0.615, -5/8, -0.62 least to greatest
ludmilkaskok [199]

Answer:

-5/8,  -0.62, -0.615

Step-by-step explanation:

For -5/8, dividing -5 by 8 will result in -0.63, that's why it's the least (the farthest negative number from 0).

Next is -0.62

Since -0.615 isn't rounded up to the nearest hundredths, it is the greatest because it's closest to 0.
