Answer:
x = 0°
Step-by-step explanation:
Given
- 2 + 6cosx = 8 - 4cosx ( add 4cosx to both sides )
- 2 + 10cosx = 8 ( add 2 to both sides )
10cosx = 10 ( divide both sides by 10 )
cosx = 1 , thus
x = (1) = 0° for 0° ≤ x ≤ 180°
Answer:
<h3>The answer is 10.2 units</h3>
Step-by-step explanation:
The distance between two points can be found by using the formula
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
U (7,-4) and V(-3,-6)
The distance between them is
We have the final answer as
<h3>10.2 units to the nearest tenth</h3>
Hope this helps you
Since she answered 90% of her quiz correct, that means if she were to answer 10 questions, 9 would be correct. Lucky for us, 50 is a multiple of 10. If you multiply 10 by 5, you'd get 50. You would also need to multiply 9 by 5 as well. When you do this you'd get
45/50 correct. (divided them to make sure you get .90 if so, I'm right :)

Answer:
Option E) is correct
If n is an odd number then 2(n+1) represents an even number.
Step-by-step explanation:
Let X=set of all odd numbers
that is
Let Y=set of all even numbers
that is
Verify that 2(n+1) represents an even number where n is an odd number:
Put n=1 in 2(n+1) we get
2(1+1)=2(2)=4
Put n=3 in 2(n+1) we get
2(3+1)=2(4)=8
Put n=5 in 2(n+1) we get
2(5+1)=2(6)=12
and so on.
From above results we get 2(n+1) represents an even number and is belongs to the set Y when n is an odd number.
Therefore Option E) is correct
If n is an odd number then 2(n+1) represents an even number.
