Round 1,819 to the nearest 100
Naddika [18.5K]

Answer:

1,800

1 is less than five so you round down even if you round the 19 to 20 it would still be needed to round down because it is less than 50.

Hope this helps, have a good day! :)

I Need Help With These
Dmitrij [34]
Notice below the picture

the one on the left-hand-side, is the 30-60-90 rule

those are the ratios, for 16), the hypotenuse (slanted side), is 4

for the ratios, that means that 4 = 2x, if you solve that for "x", that simply means "x" is 2

now, just use that value you found for "x" from the hypotenuse ratio, and use it to get the other two sides

what's the perimeter? all three sides added together

for 17)     \bf \textit{area of an equilateral triangle}\\\\
A=\cfrac{s^2\sqrt{3}}{4}\qquad s=\textit{length of one side}

Which relation is a function?
zimovet [89]

Answer:

D

Step-by-step explanation:

A relation is a set of related points. A function is a set of related points where no inputs repeat.

A. {(1, 2), (2, 3), (3,  2), (2, 1)}

This repeats (2,3) and (2,1). Not a function.

​B. {(4, 2), (3, 3), (2,  4), (3, 2)}  

This repeats (3,3) and (3,2). Not a function.

C. {(1, −1), (−2, 2), (−1,  2), (1, −2)}

This repeats (1,-1) and (1,-2). Not a function.

D. {(1, 4), (2, 3), (3,  2), (4, 1)}

This doe NOT repeat. Function.
