$\sf Hello!$

• $\sf Radius, \:r = 8\: in.$

$\sf Circumference\: of\: the\: circle$ = $\sf 2$ π $\sf r = \sf 2\cdotπ\cdot \sf 8 = \sf 16$ π $\sf in.$
$\sf with\: central\: angle\: of\: 2$ π $\sf radians$

$\sf Then,$

• $\sf Length\: of\: Arc$ = $\sf 4 \:in.$

$\dfrac{\sf 4}{\sf 16π} × \sf 2π$ = $\dfrac{\sf 1}{\sf 2} \: \sf radian$

How many different twotwo-letter passwords can be formed from the letters

Anna [14]

Answer:

$70$

Step-by-step explanation:

GIVEN: two two-letter passwords can be formed from the letters A, B, C, D, E, F, G and H.

TO FIND: How many different two two-letter passwords can be formed if no repetition of letters is allowed.

SOLUTION:

Total number of different letters $=8$

for two two-letter passwords $4$ different are required.

Number of ways of selecting $4$ different letters from $8$ letters $=^8C_4$

$=\frac{8!}{4!4!}$

$=70$

Hence there are $70$ different two-letter passwords can be formed using $8$ letters.

The volume v of a gas kept at constant temperature varies inversely with the pressure p. If the pressure is 24 pounds per square

daser333 [38]

Answer:

$V=12\ ft^{3}$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form $y*x=k$ or $y=k/x$

In this problem

$P*V=k$

step 1

Find the value of K

For $P=24\ psi ,V=15\ ft^{3}$

substitute

$24*15=k$

$k=360$

the equation is $P*V=360$

step 2

For $P=30\ psi ,V=\ ft^{3}$

substitute in the equation

$(30)*V=360$

$V=360/30=12\ ft^{3}$
