Somebody me lol

select all the correct answers.

which of these numbers are greater than 3.2 × 10^-3?

2.1 × 10^-3
4.2 × 10^-4
5.2 × 10^-2
5.2 × 10^-1

Convert all the scientific numbers to real numbers:

3.2 x 10^-3 = 0.0032

2.1 x 10^-3 = 0.0021

4.2 x 10^-4 = 0.00042

5.2 x 10^-2 = 0.052

5.2 x 10^-1 = 0.52

0.0021 and 0.00043 are less than 0.0032

0.052 and 0.52 are both greater than 0.0032

The answer would be: 5.2 × 10^-2  and 5.2 × 10^-1

y - y1 = m(x- x1)

y - (-5) = 2/3(x -0)

y + 5 = 2/3x

y = 2/3x - 5

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)
