Is 3.80012569923.... a irrational or rational ?

We can't tell from the information you've given.

With the dots at the end, you showed that there's more
to the decimal. But you didn't say how much more.

-- If the decimal EVER ends, even after a billion places,
then it's rational.

-- If it repeats, then it's rational. That .80012569923 may repeat,
or part of it, like the 9923, may repeat, or the whole thing may be
part of some larger bunch that repeats. We don't know.

Step-by-step explanation:

Here,

diameter(d) of the cylinder is 16 yd.

radius of a cylinder is 16/2 yd= 8 yd.

height (h) of a cylinder is 18yd.

now, we use formula for surface area of cylinder, 

a= 2.pi.r(r+h)

or, a= 2×3.14×8(8+18)

by simplifying it we get, 

The surface area of cylinder is 1306.24 sq.yd.

Hope it helps...

Write the following in correct mathematical language: 45.23

dexar [7]

Forty-five and twenty-three hundredths.

In general, with decimals, the first place value after the decimal is read as a tenth, the second is read as a hundredth, the third is read as a thousandth, and so on. In front of the decimal, we know that 4 is in the tens place and 5 is in the ones place, so we say forty-five. Past the decimal, 2 is in the tenths place (think about how 2/10 = .2, which is "two-tenths") and 3 is in the hundredths place (think about how 23/100 = .23). You read the number after the decimal like normal ("twenty-three," "two-hundred fifteen," etc), then you add the place ("tenths, hundredths, ten-thousands") at the very end.

Draw a line through the point (2, 0) with a slope of 1/4

Nastasia [14]

Answer:

y = 1/4 x - 1/2

Step-by-step explanation:

Remark

The general equation for a line is y = mx + b

You know that m = 1/4. The problem is what do you do about (2,0)?

Solution

y = 1/4 x + b Let x = 2 when y = 0

0 = 1/4 * 2 + b multiply 2 * 1/4

0 = 1/2 + b Subtract 1/2 from both sides

b = - 1/2

equation y = 1/4 x - 1/2
