A stick 1 meter long casts a shadow 1.4 meters long. A building casts a shadow 19 meters long. How tall is the building (to 2 decimal places)

Step-by-step explanation:

1 is to 1.4 what x is to 19

1/1.4 = x/19 (cross multiplication)

(1 * 19)/1.4 = 13.57 meters

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
