Answer:

Answer is option b)

${(x - 3)}^{2} + {(y - 4)}^{2} = 400$

Your guess was right.

Step-by-step explanation:

$the \: question \: states \: that \: \\ distance \: between \: two \: points \: is \: 20 \: units \: \\ and \: the \: two \: points \: are \: (x,y) \: \: and \: \: (3 ,- 4) \\ distance \: formula \\ = \sqrt{ {(x1 - x2) }^{2} + {(y1 - y2)}^{2} } \\ on \: substituting \: the \: values \: in \: formula \\ 20 = \sqrt{ {(x - 3)}^{2} + {(y - ( - 4))}^{2} } \\ 20 = \sqrt{ {(x - 3)}^{2} + {(y + 4)}^{2} } \\ now \: squaring \: on \: both \: sides \\ 400 = {(x - 3)}^{2} + {(y + 4)}^{2} \\ hence \: the \: answer \: is \: option \: b)$

HAVE A NICE DAY!

I am a solid figure with two congruent polygons that are bases connected with lateral faces that are rectangles

Andrews [41]

We have lateral faces that are rectangles and 2 congruent polygons that are bases. This must be 3-dimensional solid figure - quadrilateral prism. If those 2 bases are squares then it is a rectangular prism, but the bases also can be 2 rhombuses. Answer: Quadrilateral prism.

One year, the population of a city was 352,000. Several years later it was 337,920.

kvasek [131]

here is the method :

you take Value 1 and Value 2

And you do : ( Value 2 - Value 1) / (Value 1 ) * 100

Here we have : Value 1 = 352 000

Value 2 = 337 920

So now we apply :

( 337 920 - 352 000 ) / ( 352 000) * 100 = -4

Population decreased by by 4 %

You can also make :

352 000 * X = 337 920

X = 337 920 / 352 000

X = 0.96

if the multiplier is 0.96 , it's mean that we lost 1 -0.96 = 0.04

which mean - 4%

HELP PLEASE ASAP..........

Usimov [2.4K]

Volume = l x w x h
180 = l (5 x 4)
180 = 20 l
6 = l

That means that the couch will fit, because the length of the van is 6 ft, which is also the length of the couch.
