Find the area of the circle. Approximate to 2 decimal places and use 3.14 for π.

Arisa [49]

G(x) is a quadratic function with a parabolic graph that opens up and has vertex at (0,0). If we dilate this vertically by a factor of 6, we get h(x) = 6x^2.

If we translate the graph of h(x) 1 unit up and 4 units to the right, we get

k(x) = 6(x-4)^2 + 1.

Every prime number greater than 10 has a digit in the ones place that is include in wich set of numbers A- 1,3,7,9 B-1,3,5,9 D-1

marta [7]

That's very interesting. I had never thought about it before.
Let's look through all of the ten possible digits in that place,
and see what we can tell:

-- 0:
   A number greater than 10 with a 0 in the units place is a multiple of
   either 5 or 10, so it's not a prime number.

-- 1:
    A number greater than 10 with a 1 in the units place could be
    a prime (11, 31 etc.) but it doesn't have to be (21, 51).

-- 2:
   A number greater than 10 with a 2 in the units place has 2 as a factor
   (it's an even number), so it's not a prime number.

-- 3:
   A number greater than 10 with a 3 in the units place could be
   a prime (13, 23 etc.) but it doesn't have to be (33, 63) .

-- 4:
   A number greater than 10 with a 4 in the units place is an even
   number, and has 2 as a factor, so it's not a prime number.

-- 5:
   A number greater than 10 with a 5 in the units place is a multiple
   of either 5 or 10, so it's not a prime number.

-- 6:
   A number greater than 10 with a 6 in the units place is an even
   number, and has 2 as a factor, so it's not a prime number.

-- 7:
   A number greater than 10 with a 7 in the units place could be
   a prime (17, 37 etc.) but it doesn't have to be (27, 57) .

-- 8:
   A number greater than 10 with a 8 in the units place is an even
   number, and has 2 as a factor, so it's not a prime number.

-- 9:
   A number greater than 10 with a 9 in the units place could be
   a prime (19, 29 etc.) but it doesn't have to be (39, 69) .

So a number greater than 10 that IS a prime number COULD have
any of the digits 1, 3, 7, or 9 in its units place.

It CAN't have a 0, 2, 4, 5, 6, or 8 .

The only choice that includes all of the possibilities is 'A' .

How do i turn reapeating decimals into fractions?

inysia [295]

Easy example that shows $0.999\ldots=1$ :

Let $x=0.999\ldots=0.\overline9$ .

Then $10x=9.999\ldots=9.\overline9$ .

So $10x-x=9.\overline9-0.\overline9$ , or $9x=9$ , and so $x=1$ .

The basic idea is to find the period of the repeating decimal, move the $n$ digits belonging to one period over to the left of the decimal point by multiplying by $10^n$ , then subtract the original repeating decimal from this new number, and finally divide by $10^n-1$ .

A slightly more complicated example:

Let $x=0.142857142857142857\ldots=0.\overline{142857}$ .

Then $10^6x=142857.\overline{142857}$ .

Then $10^6x-x=142857.\overline{142857}-0.\overline{142857}$ , or

$999999x=142857\implies x=\dfrac{142857}{999999}=\dfrac17$
