In April 2008, an audio CD was available for $14.01. the list price (full price) of the CD was $19.32. What was the percent disc

8_murik_8 [283]

19.30 - ( p / 100 )*19.32 = 14.01 ;
19.30( 1 - p/100 ) = 14.01 ;
1 - p/100 = 14.01 / 19.30
1 - p / 100 = 0.72 ;
p/100 = 1 - 72 / 100 ;
p/100 = 28 / 100 ;
p = 28 ;
The percent discount is 28% ;

New type of pump can drain a certain pool in 5 hours. an older pump can drain the pool in 15 hours. how long will it take both p

Leno4ka [110]

New pump:
5 hours = 1 pool
1 hour = 1/5 pool

Old pump:
15h = 1 pool
1h = 1/15 pool

If both work together
1h = 1/5 + 1/15 = 4/15 pool

4/15 pool = 1 hour
1/15 pool = 1/4 hour
15/15 pool = 1/4 x 15
1 pool = 3.75 hours or 3 hours 45 mins

For the polynomial function ƒ(x) = x4 −25x2, find the zeros. Then determine the multiplicity at each zero and state whether the

AfilCa [17]

<u>ANSWER</u>

The zeros are $x=-5,x=0,x=5$

EXPLANATION

Given;

$f(x)=x^4-25x^2$ .

We can rewrite the function as

$f(x)=x^2(x^2-25)$

$\Rightarrow f(x)=x^2(x^2-5^2)$

$\Rightarrow f(x)=x^2(x-5)(x+5)$

The zeros are found by equating the function to zero.

$\Rightarrow x^2(x-5)(x+5)=0$

$\Rightarrow (x-5)=0$

The multiplicity is 1, since it is odd the graph crosses at this intercept. which is $x=5$

$\Rightarrow (x+5)=0$

The multiplicity is 1, since it is odd the graph crosses at this intercept. which is $x=-5$

$\Rightarrow x^2=0$

This last root has a multiplicity of 2.

That is

$x=0$ repeats two times.

Since the multiplicity is even, the graph touches the x-axis at the point $x=0$ .

On Saturday, $585 was collected from the sale of 55 tickets for a performance. Adult tickets are $12 and student tickets cost 25

geniusboy [140]

12(.25)= 3. 12-3= 9 for student tickets

x = adult tickets

y = student tickets

x + y = 55

12x + 9y= 585

-12x - 12y = -660

-3y = -75

3y = 75

y = 25 student tickets

x + 25 = 55

x = 30 adult tickets
