Answer:

The length of the leg is 13.416

Step-by-step explanation:

To calculate one side of a right triangle from the other 2 sides we have to use Pythagoras

h = hypotenuse  = 18

a = leg 1 = 12

b = leg 2 =

h² = a² + b²

we replace the known values  and solve

18² = (12)² + (a)²

324 = 144 + (a)²

324 - 144 = (a)²

324 - 144 = (a)²

√180 = a

13.416 = a

The length of the leg is 13.416

scZoUnD [109]
<h3>Answer:  11.55 liters</h3>

=================================================

Work Shown:

275 mL = 275/1000 = 0.275 L

1 cup = 0.275 L

6 cups = 6*0.275 L = 1.65 L

He drinks 1.65 L per day, so over 7 days he drinks a total of 7*1.65 = 11.55 liters.

Find the range for the given domain: {-2, -1, and 0} and the function is y= 3x^2
likoan [24]

Answer:

  {0, 3, 12}

Step-by-step explanation:

Put the domain values in the function and evaluate. The result is the range values.

  y = 3{-2, -1, 0}^2 = 3{4, 1, 0} = {12, 3, 0}

For the given domain, the range is {0, 3, 12}.

_____

<em>Additional comment</em>

Neither the domain nor range values need to be put in any particular order. However, it is often convenient for them to be arranged from least to greatest.
