Is 5.73773777....., -6 -3/2 0,9} rational or irrational?

1 answer:

6 0

The last four numbers ... -6, -3/2, 0, and 9 ... are rational numbers.

We can't be sure about 5.73773777..... . You haven't said whether it
goes on forever, or ends after 100 or 1,000 or a million decimal places.
If it ever ends, or if it repeats every 8 or 37 or 10,000 digits, then
this one is a rational number too.

Answer: a) y=-29x-20 b) y=3/5x-18

Step-by-step explanation:

a) m = (-49-38)/(1 - (-2)) = -87/3 = -29

y=-29x+b --> Substitute (1,-49) as a point

(-49)=-29(1)+b

-49=-29+b

-b=-29+49

b=-20

Therefore, the equation of the line is y=-29x-20

b) m = (-18-(-9)/(0-15)) = -9/-15 = 3/5

The y-intercept is (0,-18) as it's where the line intersects the y-axis and x equals 0

Therefore, the equation of the line is y=3/5x-18

seropon [69]

Answer:

B. 1,190 square cm

Step-by-step explanation:

For given prism:

l = 16 cm, w = 7 cm, h = 21 cm

Surface area of of the prism

$= 2 (lw + wh + hl) \\ = 2(16 \times 7 + 7 \times 21 + 21 \times 16) \\ = 2(112 + 147 + 336) \\ = 2 \times 595 \\ = 1190 \: {cm}^{2} \\$
