Answer:

7.2 *10⁻⁵

Step-by-step explanation:

Given the diameter of the hair expressed as 0.000072, we are to express it in scientific notation.

The standard form of scientific notation is expressed as;

A * 10ⁿ

A is a value from 1 to 9

n is any integer.

Rewriting 0.000072 in this form, we will need to shift the decimal point to the front 5 times to have;

0.000072 = 7.2 *10⁻⁵ where;

A = 7.2 and n = -5

Note that the power is a negative value since the value is less than 1.

rusak2 [61]

rank | 1st | 2nd |TOTAL
------|-----+-------|----------
a     | 6   +    9   |  =15
b     | 7   +   3    | =16
c     | 9   +   7    | =23
d     | 6   +   7    | =22
e     | 8   +  1     | =?


If you add the 1st in line a (6) and you add it to the 1st in line b (7) + the 2nd in line b (3) you get 16. Repeat the same logic/pattern to all c,d..
This is the pattern to all this puzzle;

So the before last term is :  9+6+7 = 22
and the last term : 6+8+1 = 15

Everett made 3/5 of the baskets he shot suppose he shot 60 baskets how many did he make
givi [52]
As given he made  3/5 of basket he shot.

So we can find number of basket made by Everett equal to 3/5 of total number of shot .

So if total number of shot is 60.

Then the number of basket made by Everett = \frac{3}{5} of 60.
                                                                            \frac{3}{5} * 60 =  \frac{3 * 60}{5} =  \frac{180}{5} = 36

So the number of basket made by Everett in 60 shots = 36.

Find the surface area of the part of the sphere x2+y2+z2=81 that lies above the cone z=x2+y2−−−−−−√
TiliK225 [7]
Parameterize the part of the sphere by

\mathbf s(u,v)=(9\cos u\sin v,9\sin u\sin v,9\cos v)

with 0\le u\le2\pi and 0\le v\le\dfrac\pi4. Then

\mathrm dS=\|\mathbf s_u\times\mathbf s_v\|=81\sin v\,\mathrm du\,\mathrm dv

So the area of S (the part of the sphere above the cone) is given by

\displaystyle\iint_S\mathrm dS=81\int_{v=0}^{v=\pi/4}\int_{u=0}^{u=2\pi}\sin v\,\mathrm du\,\mathrm dv=81(2\pi)\left(1-\dfrac1{\sqrt2}\right)=(162-81\sqrt2)\pi
