Which irrational number is represented by point B?

avanturin [10]

Answer:

B) √229

Step-by-step explanation:

√229 is about 15.13, which is the approximate location of point B.

IMO, the dot at point P is a little too far to the right for √229.

M is the midpoint of JK. Find the coordinates of K. J(0, 11), M(-3,2)

cluponka [151]

Let's assume

point K as (x,y)

M is the midpoint of JK

so, other point as J(0, 11)

M(-3,2)

$(-3,2)=(\frac{0+x}{2},\frac{11+y}{2})$

now, we can compare both sides

Calculation of x-coordinate:

we get

$-3=\frac{0+x}{2}$

$x=-6$

Calculation of y-coordinate:

we get

$2=\frac{11+y}{2}$

$11+y=4$

$y=-7$

so, we will get point K

K=(-6,-7)............Answer

Naily [24]

Answer:

1/18

Step-by-step explanation:

$( {2}^{ - 3} \times {16}^{ \frac{1}{2} } ) \div ( {81}^{ \frac{3}{4} } \times {27}^{ - \frac{1}{3} } ) \\ \\ =( {2}^{ - 3} \times {2}^{ \frac{4 \times 1}{2} } ) \div ( {3}^{ \frac{4 \times 3}{4} } \times {3}^{ - \frac{3 \times 1}{3} } ) \\ \\=( {2}^{ - 3} \times {2}^{ 2} ) \div ( {3}^{ 3 } \times {3}^{ - 1 } ) \\ \\=( {2}^{ - 3 + 2} ) \div ( {3}^{ 3 - 1 } ) \\ \\ = {2}^{ - 1} \div {3}^{2} \\ \\ = \frac{1}{2} \times \frac{1}{9} \\ \\ = \frac{1}{18}$
