Answer:

0.1, 0.18, 0.21, 0.222, 0.24

Explanation:

look at the first number:

between 0.1 and 0.18, 0.1 is smaller therfore it is the least

next to that would be 0.18

next, 0.21, 0.222, and 0.24 all has the same first number so take a look at the second number:

0.21 would be the third number since the second number is 1, which is the smaller number out of 3

the 4th number would be 0.222 because 0.22 is less than 0.24

lastly, the greatest or largest number would 0.24

Answer:

AB = 1.4 or 7/5

Step-by-step explanation:

(Excuse my rambling but I wanted to be sure of myself)

AD = 2(5/2) = 5

AD is a diameter.

any triangle in a circle with the hypotenuse as the diameter is a right triangle.

Draw a line from point A to point C.

ΔACD is a right triangle.

Solve for ∠CAD:

sin CAD = 3/5 = 0.6000

∠CAD = 36.87°

arc CD = 2 x 36.87°  = 73.74°

arc BC = arc CD = 73.74°

arc DB = 147.48°

∠BAD = 1/2 (147.48°) = 73.74°

draw a line from point D to point B

ΔBAD is a right triangle.

cos 73.74° = AB/5

AB = 1.4

Answer:

A and B

Step-by-step explanation:

[2,∞)

Answer:

it's 2

Step-by-step explanation:

Answer:

Presumably this is a multiple choice question, and without seeing the potential answers, we can't tell you which ones are correct.

A few things can however be said about this function:

1) It describes a parabola that extends upward infinitely.  We can see this because it's in the classic format ax² + bx + c, and all terms are positive.

2) We can find the x-intercepts by solving for zero.  In this case we can do that by factoring it:

x² + 9x + 18 = 0

x² + 3x + 6x + 18 = 0

x(x + 3) + 6(x + 3) = 0

(x + 6)(x + 3) = 0

So the x intercepts occur at (-6, 0) and (-3, 0)

3) we can find its vertex by taking its derivative and solving for zero:

f'(x) = 2x + 9

0 = 2x + 9

x = -4.5

We can then plug that coordinate into the original function to find the y coordinate:

f(x) = x² + 9x + 18

f(-4.5) = 20.25 - 40.5 + 18

= -2.25

So the vertex is at (-4.5, -2.25)

4) As mentioned, the derivative of f(x) is f'(x) = 2x + 9.  The integral is:

x³ / 3 + 9x² / 2 + 18x + C

Sally picked 1/10 of a basket more than Maggie picked

Answer:

1 this could change depending on how many berries are in each basket

Step-by-step explanation:

2/5 = 0.4

2/4 = 0.5

answer is 4√2

because, using pythagoras theorem

x² = 4² + 4²

x² = 16 + 16

x² = 32

x = √32

x = √(16 × 2)

x = √16 × √2

x = 4 × √2

x = 4√2

Step-by-step explanation:

Plus these numbers

2:18:09

5:34:27

_______

2+5 = 7

18+34 = 52

09+27 = 36

7:52:36

Answer: 7

Step-by-step explanation: So 24:28 is equal to 6:? so if we divide 24 by 6 we get 4. So 28 divided by 4 is 7. 6:7 is equal to 24:28.
