Archy [21]

First covert the feet to meters.

1 meter = 3.3 feet.

Divide the total number of feet by 3.3 to get total number of meters:

198 / 3.3 = 60 meters per second.


Multiply meters per second by 15 seconds:


60 x 15 = 900 meters in 15 seconds.

P=175e^-0.090times 25
zysi [14]

Here's my interpretation of your equation:


P=175e^(-0.090*25) (not P=175e^-0.090times 25 )


Then P = 175(0.105) = 18.4, or approx 18.

Using the equation x squared minus c equals 0 , what value of c has 9 and -9 as solutions.
Svetach [21]

9514 1404 393

Answer:

  c = 81

Step-by-step explanation:

The equation x² -c = 0 can be factored as ...

  (x -√c)(x +√c) = 0

which has roots ±√c.

The roots are given as ±9, so we have ...

  ±9 = ±√c

  c = (±9)² = 81

The value c = 81 makes the equation have ±9 as solutions.
