A polynomial has been factored, as shown below: f(x) = (x − 6)(x + 5)(x − 9) What are the zeros of the polynomial? (5 points)
soldi70 [24.7K]

<span>x=6</span>, <span>x=−5</span> or <span>x=9</span>

Explanation:

<span><span>f<span>(x)</span></span>=<span>(x−6)</span><span>(x+5)</span><span>(x−9)</span></span>

If all of the linear factors are non-zero, then so is their product <span>f<span>(x)</span></span>.

If any of the linear factors is zero, then so is their product <span>f<span>(x)</span></span>.

A coach purchases 47 hats for his players and their families at a total cost of $302. The cost of a small hat is $5.50. A medium
bazaltina [42]
First, we define variables:
 x: small hat
 y: medium hat
 z: large hat
 We now write the system of equations:
 x + y + z = 47
 5.50x + 6y + 7z = 302
 -3x + y = 0
 We can write the system in matrix form as:
 Ax = b
 Where,
 A = [1  1  1; 5.50  6  7; -3  1  0]
 b = [47;  302;  0]
 x = [x;  y ;  z]
 Solving the system we have:
 x = 6
 y = 18
 z = 23
 Answer:
 
the coach did purchase 23 large hats
 
d. 23

If sin phi sin theta = 0.2 and sin phi cos theta = -0.3 and sin phi &gt; 0 what is theta ? Repeat for sin phi &lt; 0.
Rina8888 [55]

Answer:

θ = -33.69°

Step-by-step explanation:

For Φ>0 and Φ<0  (in general Φ≠nπ  where n is an integer), sin(Φ) ≠ 0

Dividing both equations:

\frac{sin(\phi) sin(\theta)}{sin(\phi)cos(\theta)} = tan(\theta) = 0.2/(-0.3)=-2/3\\

Therefore:

arctan(θ) = -2/3

  θ = -33.69°

The answer does not depend on the sign of Φ, in fact we just need that the sine does not become zero, which occurs when Φ is equal to an integer times π (radians) or 180 (degrees)

Have a nice day!

Ben is reading a book. Rounded to the nearest ten, he reads 150 pages. What is the least number of pages he could read?
Semenov [28]
145 pages because 145 would round up to 150 but anything below 145 would round to 140
