2.4*10^-3
when you make a small number scientific notation, it will be negative. there has to be one number in the ones place for it to be written correctly. hope this helps!
The equation of this line would be (x - 7)^2 + (y + 24)^2 = 625
This is because of the base equation for circles, which is:
(x - x1)^2 + (y - y1)^2 = r^2
In which, x1 is the x-coordinate to the center, y1 is the y-coordinate to the center and r is the radius.
So we start by putting in out known values.
(x - 7)^2 + (y + 24)^2 = r^2
However, we still don't know the r value. To find it, we must use the Pythagorean Theorem to find the distance between the center and the origin.
a^2 + b^2 = c^2
7^2 + 24^2 = c^2
49 + 576 = c^2
625 = c^2
25 = c
So we know the radius must be 25. So we can plug that into what we already had.
(x - 7)^2 + (y + 24)^2 = 25^2
(x - 7)^2 + (y + 24)^2 = 625
To solve this problem, let's set up a proportion, letting x represent the unknown number of gallons the faucet loses in 48 hours.
5 gallons / 20 hours = x gallons / 48 hours
To solve this proportion, we are going to use cross-products. This is the products of numerator of one fraction and the denominator of the other fraction set equal to one another. It results in the equation:
5 * 48 = 20 * x
Next we simplify by performing the operations.
240 = 20x
Finally, we divide both sides by 20 to get x alone on the right side of the equation.
12=x
Therefore, 12 gallons of water will be lost in 48 hours.
