The x intercepts of the function f(x) = 2x(x-5)^2(x+4)^3<br> are…

Leokris [45]

Answer:

$\boxed{\sf x- intercepts = 0 , 5 \ and \ -4}$

Step-by-step explanation:

A function is given to us and we need to find the x Intercepts of the graph of the given function . The function is ,

$\sf \implies f(x) = 2x( x - 5 ) ^2(x+4)^3$

For finding the x intercept , <u>equate the given function with 0, we have ;</u>

$\sf \implies 2x ( x - 5 )^2(x+4)^3= 0$

Equate each factor with 0 ,

$\sf \implies 2x = 0$

Divide both sides by 2 ,

$\sf \implies\bf x = 0$

Again ,

$\sf \implies ( x - 5)^2=0$

Taking squareroot on both sides,

$\sf \implies x - 5 = 0$

Add 5 to both sides,

$\sf \implies \bf x = 5$

Similarly ,

$\sf \implies \bf x = -4$

<u>Hence</u><u> the</u><u> </u><u>x </u><u>Intercepts</u><u> </u><u>are </u><u>-</u><u>4</u><u> </u><u>,</u><u> </u><u>0</u><u> </u><u>and </u><u>5</u><u> </u><u>.</u>

Solve for r.<br> –5 ≥ 5 (r+5)

aleksandr82 [10.1K]

Answer:

-6 ≥ r

Step-by-step explanation:

–5 ≥ 5 (r+5)

Divide each side by 5

–5/5 ≥ 5/5 (r+5)

–1 ≥ (r+5)

Subtract 5 from each side

-1-5 ≥ r+5-5

-6 ≥ r

You survey 200 people about the electronics they own. The results show that 33/40 people own a cell phone. Of these people, 10/1

guajiro [1.7K]

200 * 33/40 = 165 owns phones
165 * 10/11 = 150 owns phones and MP3 player

Therefore 3/4 owns both and
165 owns only phones
