Answer:
40%
Step-by-step explanation:
I'm assuming that there is another root which should be -SQRT(11)
f(x) = x(x-4)(x+SQRT(11))(x-SQRT(11)
Then
f(x) = x^4 -4x^3 - 11x^2 +44x
Answer:
Step-by-step explanation:
What we need to do is figure out the answer to, "1/2 of 1/8 is how many?" 2/4 reduces to 1/2. If 1/8 of the flowers are tulips, and 1/2 the tulips are red, then 1/2 * 1/8 is the number of red tulips, which is 1/16.
Answer:
Step-by-step explanation:
Given
Two sides of a triangle; 34 and 12
Required
Determine the range of the third side
Represent the third side with X
To determine the range of the third side; two of the following conditions must be satisfied'
Solving 34 + X > 12
<em>Subtract 34 from both sides</em>
Solving 34 + 12 > X
Solving 12+ X > 34
<em>Subtract 12 from both sides</em>
Write out the results
The first inequality will be discarded because it accommodates negative digits;
<em>So, we're left with</em>
and
This can be rewritten as
and
Combine both inequalities;
Hence, the range of the third length is
Radiologically, half lives describe the amount of time it takes for half the amount of the radioactive substance to decay. If you had 100g of a radioactive substance with a half life of one week, in seven days, only 50g would remain, and after another week, only 25g.
Fifteen days contains three half lives since the half life is 5 days long. Divide the starting amount by 2 for each half life that passes.
600g - 300g (1 HL) - 150g (2 HL) - 75g (3 HL)
So, only 75g of Bismuth-210 would remain after 15 days.
