A pipe that is 3.1 meters long is placed vertically in a pond. Its lowest point is 1.5 meters under the water surface. How far a

amm1812

Answer:

1.6 above water

Step-by-step explanation:

Total length of the pipe = length below the water + length above the water

We know the total length of the pipe =3.1 and the length below the water is 1.5 m

3.1 = 1.5 + length above the water

Subtract 1.5 from each side

3.1 -1.5 = 1.5 -1.5 + length above water

1.6 = length above water

I NEED HELP :_( Which of the following points is in the solution set of y > -x∧2 + 5? (0, 5) (2, 4) (1, 3)

marysya [2.9K]

Answer:

$\huge\boxed{(2;\ 4)}$

Step-by-step explanation:

We have

$y>-x^2+5$

Put the coordinates of the given points and check the inequality:

For (0; 5) → x = 0; y = 5

$5>-0^2+5\\5>0+5\\5>5\qquad\bold{FALSE}$

For (2; 4) → x = 2, y = 4

$4>-2^2+5\\4>-4+5\\4>1\qquad\bold{TRUE}$

For (1; 3) → x = 1, y = 3

$3>1^2+5\\3>1+5\\3>6\qquad\bold{FALSE}$
