A is NOT a function because for some values of x you get more than one y value. For example if x=2 you get 2 values for y.
b is a function because for each x you get ONLY one y

How would you solve 4n-2n=4?

Nezavi [6.7K]

Answer:

n = 2

Explanation:

Simplify both sides of the equation

4n − 2n = 4

4n + −2n = 4

(4n + −2n) = 4 (Combine Like Terms)

2n = 4

Divide both sides by 2

2n / 2 = 4 / 2

n = 2

A large railroad car is filled with 1745 gallons of milk. The car springs a leak in the bottom, and milk starts dripping out at

jeka57 [31]

Answer:

585.98 miles

Step-by-step explanation:

We need to convert 1745 gallons to mL.

We know 1 gallons = 3785.41 mL

So 1745 gallons = 1745 * 3785.41 = 6,605,540.45 mL

Leaks are at 204.84 mL/sec, so it will take:

6,605,540.45/204.84 = 32,247.32 seconds

In hours, that is:

32,247.32/(60*60) = 8.96 hours

Now, since train is travelling at 65.4 miles per hour, in 8.96 hours, train will approximately travel:

65.4 * 8.96 = 585.98 miles

Find the center and radius of this circle.<br> x2 + y2 − 40x − 24y + 15 = 0

Julli [10]

ANSWER

Center: (20,12)

Radius:23

EXPLANATION

The given circle has equation:

${x}^{2} + {y}^{2} - 40x - 24y + 15 = 0$

We complete the square as follows:

${x}^{2} - 40x + {y}^{2} - 24y = - 15$

${x}^{2} - 40x + {( - 20)}^{2} + {y}^{2} - 24y + {( - 12)}^{2} = - 15+ {( - 20)}^{2}+ {( - 12)}^{2}$

${(x - 20)}^{2} + {(y - 12)}^{2} = - 15+ 400+ 144$

${(x - 20)}^{2} + {(y - 12)}^{2} = 529$

${(x - 20)}^{2} + {(y - 12)}^{2} = {23}^{2}$

Comparing this equation to:

${(x - h)}^{2} + {(y - k)}^{2} = {r}^{2}$

We have

$(h,k)=(20,12)$

representing the center and

$r = 23$

being the radius.
