You so much to anyone who answers

A. The third rocket is launched at 6 seconds.

B. It approximately lands at 7.25.

C. All rockets are in the air from 6 seconds to 7.25 seconds.

Step-by-step explanation:

Remember that the x value represents the time.

A. The third rocket is launched at 6 seconds.  We can tell because the third curve starts at x=6.

B. It approximately lands at 7.25.  We can tell because the first curve reaches a height of zero (y=0) when the x value is in between 7 and 8.

C. All rockets are in the air from 6 seconds to 7.25 seconds.  We know this because the third rocket is not launched until about 6 seconds, and the first rocket lands at about 7.25 seconds.  So all three are in the air in between that that time.

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
