Answer:

(a) N{A∩B} = 0

(b) N{A∪B} = 9

Step-by-step explanation:

Union of two sets: This can be defined as the sum of all the elements of the two sets without writing one element twice. it is denoted by the symbol ∪

Intersection of two sets; This is the set of elements that appears in both sets. It is denoted by the symbol ∩

From the question above,

assuming there is no repetition element in both set,

(a) The smallest number possible for N{A∩B} = 0

(b) The largest number possible for N{A∪B} = 4+5 = 9.

Tbh this question confusing the **** outta me​
trapecia [35]

Answer:

8^6

Step-by-step explanation:

Powers are defined as the number of times you multiply a number by itself. For example, 2 to the 3rd power is 2 multiplied by itself 3 times. 2 * 2 * 2 = 8. You also know that if you multiply two powers of the same base, you add the exponent, and if you raise a power to a different power, you multiply the exponents.

e.g:

2^2\cdot2^2=2^{2+2}=2^4\\(2^2)^3=2^{2\cdot3}=2^6

Now, we are asking to use grouping to write 2 to the power 18 as a power of 8. We know 2 to the power 8 is 2 to the power 3, so we have the following equation:

2^{18}=(2^3)^x

We know this is now 2 to the power 3x = 2 the power 18, and therefore x = 6, because 3 times 6 is equal to 18. Now, we can just simplify 2 to the third as 8 and we now have:

8^6

write a quadratic function that has a graph that contains the following points, (-2, 0), (4, -12), (5,0).
ankoles [38]

Answer:

f(x) =  2x^2 - 6x - 20.

Step-by-step explanation:

(-2, 0) and (5, 0)  are 2 zeroes of the function so we can write the function as

f(x) =  a(x + 2)(x - 5)   where a is a constant.

Now as (4, -12) is a point on the graph:

-12 = a(4 + 2)(4 - 5)

-12 = a * 6 * -1

-6a = -12

a = 2.

So f(x) = 2(x + 2)(x - 5)

f(x) =  2x^2 - 6x - 20.
