Find the third degree function that has zeros 7 and −11i, and a value of 663 when x=10.

slega [8]

Answer:

$y = x^3 - 7x^2 + 121x + 847$

Step-by-step explanation:

If -11i is a zero, its conjugate also is a zero, so the zeros are:

7, 11i and -11i.

So we can write the third degree function as:

$y = a(x-7)(x-11i)(x+11i)$

$y = a(x-7)(x^2+121)$

If the function has a value of 663 when x = 10, we have:

$663 = a(10-7)(10^2+121)$

$663 = a(3)(221)$

$a = 663/663 = 1$

So the function is:

$y = (x-7)(x^2+121)$

$y = x^3 - 7x^2 + 121x - 847$

Answer:

$\large\boxed{\dfrac{m^3}{kg}}$

Step-by-step explanation:

$P=\dfrac{h\cdot d}{m}\\\\H\to m^2\\d\to m\\m\to kg\\\\P=\dfrac{h\cdot d}{m}\ \bigg(\dfrac{m^2\cdot m}{kg}\bigg)=\dfrac{h\cdot d}{m}\ \bigg(\dfrac{m^3}{kg}\bigg)$

The All-Clean Laundry Company washes towels for a nearby hotel. The function f(x) gives the number of loads required whenthere a

NISA [10]

Answer:

B.It takes more than 12 loads to wash 9 bins of towels.

Step-by-step explanation:

The function f(x) gives the number of loads required when there are x bins of towels to be washed.

f(x)=Number of loads

x=Bins of towels

Therefore in the inequality f(9)>12

Number of loads=12
Bins of towel =9

If f(9)>12, it means Number of loads is more than 12.

f(9)>12 therefore tells us that it takes more than 12 loads to wash 9 bins of towels.

The correct option is B
