Which numbers are perfect squares? Determine their square roots. 5 20 16 49 100 1000

Please help

Only 16

Step-by-step explanation:

The square roots of 5 & 20 are long decimals.

The square root of 49 is 7 but 7 has a decimal square root.

The square root of 16 is 4, 4 is 2 squared.

So 16 is a perfect square.

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
