If (x+2) Is a factor of x^3-6x^2+kx+10 k=?
1 answer:
The value of k is -11
Further explanation:
Any number being a factor states that the value of expression will be equal to zero at the factor.
Given
and
x+2 is a factor
x+2 = 0
x=-2
If x=-2 is a factor of given expression then the expression will be zero at x=-2
So.
The value of k is -11

The solution is completely correct, as putting 5 or 0 in the formula again will make it true.
Answer:
∛27 = 3
Step-by-step explanation:
A radical is simply a fractional exponent:
Hence, ∛27 =
Since 27 = 3³, then:
You could rewrite ∛27 as ∛(3)³.
Multiplying the fractional exponents (3 × 1/3) will result in 1 (because 3 is the <u><em>multiplicative inverse</em></u> of 1/3). The multiplicative inverse of a number is defined as a number which when multiplied by the original number gives the product as 1.
Therefore, ∛27 = 3.
Answer:
Step-by-step explanation:
First, we need to look at the # of chips. There are a total of 25, 6 of which are blue.
This means that the chance of getting the first blue chip would be
As there is no replacement, the total number of chips is 24 and there are only 5 blue left. This gives us the chance of
Now all we need to do is mulitply these two and then simplify
