Please help i have no idea what are the excluded values to the equation y = 5 / (x^2 - 7x 10)?

1 answer:

5 0

Hello,

The excluded values are the roots of the denominator.

x²-7x+10=x²-2x-5x+10=x(x-2)-5(x-2)=(x-2)(x-5)

Roots of the denominator are x=2 and x=5

Xelga [282]

Answer:

254/324 which is about 78.4%

Step-by-step explanation:

found area of 4-quarter circles - which equals one circle with radius of 9

A = 81π which is about 70

Ruben put an empty cup underneath a leaking faucet. After 1 1/2 hours, Ruben had collected 1/4 cup of water. What is the rate, i

worty [1.4K]

Answer:

The rate is $\frac{1}{6}$ cups per hour

Step-by-step explanation:

It took the faucet 1 1/2 hours, i.e 1.5 or 3/2 hours to fill 1/4 cup by leaking

We need to find the rate in terms of cups that can be filled by water in 1 hour.

Using unitary method:

If it takes $\frac{3}{2}$ h for $\frac{1}{4}$ cup;

then it will take 1 h for how many cups?

$= \frac{1 \times \frac{1}{4} }{\frac{3}{2} }$

$= \frac{2}{4 \times 3}$

$= \frac{2}{12}$

$= \frac{1}{6}$ cups

Therefore, the rate is $\frac{1}{6}$ cups per hour
