Answer:
The answer is B
Step-by-step explanation:
We have to substitute values for this.
f(1) = 1/2(2)^1
f(1) = 1
Now we can eliminate D and A
f(3) = 1/2(2)^3
f(3) = 4
f(6) = 1/2(2)^6
f(6) = 32
Answer is B
Answer:
a) A = {-3, -2, -1}
b) n(A) = 3
c) A is finite
Step-by-step explanation:
a) The elements of A are the integers between -4 and 0, not including those values. Those integers are -3, -2, -1, so those are the elements of set A.
A = {-3, -2, -1}
__
b) n(A) is the number of elements in set A. Obviously, there are 3:
n(A) = 3
__
c) Since n(A) is not "infinity", the set A is finite.
It's 1,000,000:
<span>the sum is 1 + 3 + 5 + ... 1999999 </span>
<span>= 1 + 2 + ... + 2000000 - 2*(1 + ... + 1000000) </span>
<span>= 2000000*2000001/2 - 2*(1000000*1000001 / 2) </span>
<span>= 1000000*(2000001 - 1000001) = 1000000000000 (one million million) </span>
<span>and dividing this by one million to get the average, </span>
<span>you get one million</span>
Answer:
3(2m-9n)
Step-by-step explanation:
Find the greatest common denominator take it out and add what you have left. When you work this out you get 6m-27n
The measure of the vertex angle of the isosceles Δ is 96°
Step-by-step explanation:
In the isosceles triangle
- Two sides are equal in lengths
- The angle between the two equal sides is called vertex angle
- The other two angles are called base angles
- The base angles are equal in measure
∵ The measure of one of the base angles of an isosceles Δ = 42°
- The base angles are equal in measure
∴ The measure of the other base angle = 42°
∵ The sum of the measures of the interior angles of any Δ = 180°
∴ 42 + 42 + measure of the vertex angle = 180
∴ 84 + measure of the vertex angle = 180
- Subtract 84 from both sides
∴ measure of the vertex angle = 96°
The measure of the vertex angle of the isosceles Δ is 96°
