Find the distance between (4,2) and (-4,-4)

VikaD [51]

Use the distance formula, and plug in values.
$d = \sqrt{(x_{2}-x_{1} )^{2}+(y_{2}-y_{1} )^{2}}$
 $d = \sqrt{( -4-4 )^{2}+( -4-2 )^{2}}$
$d = \sqrt{( -8 )^{2}+( -6 )^{2}}$
$d = \sqrt{64+36}$
$d= \sqrt{100}$

Therefore, the distance is equal to "10".

the perimeter of a pool table is 30 ft.The table is twice as long as it is wide.what is the length of the pool table.

noname [10]

Perimeter is legnth +legnth + width + width or
P=2L+2W

L=2W
subsitute L=2W for L in P=2L+2W

P=2(2W)+2W
P=4W+2W
P=6W

we know that Perimiter=30 so
30=6W
divide both sides by 6
5=Width

subsitute W=5 for W in L=2W
L=2(5)
L=10

to check
10=2(10)+2(5)
30=20+10
30=30
checks

Legnght=10
Width=5

Find the height of the pyramid.

SOVA2 [1]

Answer:

Step-by-step explanation:

Let the height of pyramid be h

$v = \frac{1}{3} lwh$

v= 224

w= 8

l= 12

224=1/3(12)(8)(h)

224=32h

h=224/32

h=7
