Answer :
18%
Step by Step :
42.64/52=0.82
0.82*100=82
100-82=18
Answer:
A
Step-by-step explanation:
To solve this I first solved the equation for how many rabbits there would be after 1 year
1000+ .40×(1400)
This is going to give me the number of rabbits at first, + 40% of the initial population.
After the first year there would be 1400 rabbits.
While choice C does equal 1400, this equation only gives you the population increase for 1 year. Answer A allows you to find the population for any year.
Answer:
B ∪ C = (-∞, ∞)
B ∩ C = [1, 7)
Step-by-step explanation:
B ∪ C: The union of two sets or intervals is the set of elements which are in <em>either </em>set.
B ∩ C: The intersection of two sets or intervals is the set of elements which are in <em>both </em>sets.
<u>Interval notation symbols</u>
Square brackets [ ]: both endpoints are included in the set.
Round brackets ( ): both endpoints are excluded in the set.
Round, square ( ]: left endpoint is excluded and right endpoint is included in the set.
Square, round [ ): left endpoint is included and right endpoint is excluded in the set.
Given:
- B = {z | z ≥ 1}
- C = {z | z < 7}
Therefore,
B = [1, ∞)
C = (-∞, 7)
Therefore, B ∪ C = (-∞, ∞)
As z is either less than 7, or equal to or more than 1 then the intersection is:
B ∩ C = {z | 1 ≤ z < 7} = [1, 7)
x simply equals six. This is because 4 x 6 + 5 = 5 x 6 - 1.
Hope this helps!
Answer:
1/2x^2 -3
Step-by-step explanation:
The first equation is 1/2x^2 + 1 and since this equation is the first one minus 4 1-4= -3 so you would get this new equation.
