Answer:

A. f(x)=(x+6)(x+2)(x-3)

Step-by-step explanation:

The zeros or roots of a function are the numbers that when they are entered into the function the output will be 0.

We will evaluate the given numbers (-6,-2,3)to see in wich option all of them wil give us 0 in the output, Let´s start with the first option A) as follows:

f(-6)=((-6)+6)((-6)+2)((-6)-3)=(0)(-4)(-9)=0

f(-2)=((-2)+6)((-2)+2)((-2)-3)=(4)(0)(-5)=0

f(3)=((3)+6)((3)+2)((3)-3)=(9)(5)(0)=0

As we can see this is the correct option in which all of the values give us the output 0 adn we dont need to evaluate the resto of the options (B), C) and D))

Dingane has \$8.00$8.00dollar sign, 8, point, 00, and exactly 30\%30%30, percent of that money is from 555‑cent coins. How many
Ipatiy [6.2K]
<span>If Dingane has $8.00, and thirty percent of that money is from five cent coins, then 8 x 0.3 = $2.40 of Dingane's money is made of five cent coins. In this case the number of five cent coins is the number of cents divided by five: 240/5 = 48. Therefore, Dingane has forty-eight five-cent coins.</span>

(a) Find an angle between 0 and 2π that is coterminal with −19π10.
Katarina [22]

Answer:

\dfrac{\pi}{10}.

Step-by-step explanation:

All coterminal angles of an angle \theta are defined as

\theta +2n\pi or \theta + n360^{\circ}

where, n is an integer.

The given angle is

\theta=-\dfrac{19\pi}{10}

So, all coterminal angles of an angle \theta are

-\dfrac{19\pi}{10}+2n\pi

For n=1,

\Rightarrow -\dfrac{19\pi}{10}+2(1)\pi

\Rightarrow -\dfrac{19\pi}{10}+2\pi

\Rightarrow \dfrac{-19\pi+20\pi}{10}

\Rightarrow \dfrac{1\pi}{10}

Since,  \dfrac{\pi}{10}  between 0 and 2π, therefore,  the required coterminal angle is \dfrac{\pi}{10}.
