Answer:
The values of k will be:
Step-by-step explanation:
Let the expression of polynomial P be
Let the expression if the polynomial Q be
Plug in Q(x) = 0
0 = x+2
x = -2
As (x+2) is a factor of 3x²-4kx-4k²
substitute x = -2 in the the polynomial
3x²-4kx-4k² = 0
Write in the standard form ax²+bx+c = 0
Factor out common term -4
Factor k²-2k-3: (k+1)(k-3)
Using the zero factor principle
if ab=0, then a=0 or b=0 (or both a=0 and b=0)
solving k+1=0
k+1 = 0
k = -1
solving k-3=0
k-3=0
k = 3
Thus, the values of k will be:
<span> At the beginning there are 3 dimes out of 10 coins:
P(first coin is a dime) = 3/10
After that there are 3 nickels out of 9 remaining coins:
P(second coin is a nickel) = 3/9 = 1/3
P(dime, then nickel) = P(first coin is a dime) x P(second coin is a nickel)
= 3/10 x 1/3
= 1/10
Answer:
1/10 . if im wrong im sorry </span>

Answer:
i think 7% but i could be wrong
Step-by-step explanation:
sorry if im wrong :(
Answer:
No.
Step-by-step explanation:<u> If we look at the first conveyor belt, the rate is 12ft in 3 seconds, or 4 feet a second. The second conveyor belt moves at 21 feet in 7 seconds, or 3 feet a second. Since the two values are unequal, we can conclude it is not a proportional relationship. </u>
Two hours bc if it takes 8 to do it in one hour and u split the number of men u have in half you double the work hours 8men=1hour of work 4men=2hours of work
Hope this helps have a nice day
