Answer:
Step-by-step explanation:
So if you expand out the two binomials (k-2)(k+1), you'll get: 
. which simplifies to: 
. Multiplying this by the k gives you: 
. As you can see the degree is odd, this means that this polynomial will have two opposite end behaviors. And as you can see the leading coefficient is positive, meaning that this function will go towards positive infinity as k goes towards positive infinity. Also we if look at the original equation given, it's in factored form, with the zeroes as k=0, k=2, and k=-1. So given this we can draw a simple graph to see when the value of the equation is negative. If you look at the graph I drew you'll see that it's negative from (-infinity, -1) and then negative from (0, 2)
Answer:
x= 15
Step-by-step explanation:
Just add 7 on both sides. The side with the x will have only an x and it would look like this x=15.
You can do 12/12 8/8 10/10 3/3 and 2/2 all equal to 6/6 all in different ways.
Answer:
cos∠F = √15/15 ⇒ answer (D)
Step-by-step explanation:
∵ cos∠F = EF/FG
∵ EF = 2
∵ FG = 2√15
∴ cos∠F = 2/2√15 = 1/√15 ⇒ multiply yp and down with √15
∴ cos∠F = √15/15 ⇒ answer (D)

Answer:</h2>
0.5 x 0.11 is equal to 0.055 <u>because of the zeros and the decimal placements.</u>
<h2>
Step-by-step explanation:</h2><h3>
How does it work?</h3>
Even though it would seem like the answer would be 0.55, the decimal placement of 0.5 makes it so that the number would change to an extra zero in the final result.
