Answer:
sin A = 0.69
Step-by-step explanation:
sin A = 20 / 29 = 0.69
Answer:
9.73
Step-by-step explanation:
for the second part of the equation, h was supposed to be there instead of x but the height is 9.73
The answer is D, all the y points are positive if it is reflected over the x axis
Answer:
- AP
- tₙ = (n-2)k² + (2n - 3)k + n
Step-by-step explanation:
<u>Given sequence:</u>
- -k² - k + 1, k + 2, k² + 3k + 3, 2k² + 5k + 4, ...
We can see apart from the second term all terms are 2nd degree trinomial so it is not a GP.
Let's find the difference: to determine if it is a AP:
- k + 2 - (-k² - k + 1) = k + 2 + k² + k -1 = k² + 2k + 1
- k² + 3k + 3 - (k + 2) = k² + 3k + 3 - k - 2 = k² + 2k + 1
- 2k² + 5k + 4 - (k² + 3k + 3) = 2k² + 5k + 4 - k² - 3k - 3 = k² + 2k + 1
As we see the difference is common and it confirms the sequence is AP.
<u>First term is </u>
<u>Common difference is </u>
<u>nth term is:</u>
- tₙ = a₁ + (n-1)d
- tₙ = -k² - k + 1 + (n-1)(k² + 2k + 1) =
- -k² - k + 1 + (n-1)k² + (n-1)*2k + n-1 =
- (n-2)k² + (2n - 3)k + n
Answer:
It would be x=3, f(x)=0
Step-by-step explanation:
This is because an asymptote is the line where a function is approaching infinity towards.
On the graph, you see that the function it stretching out towards what is x=3, along with the x axis, which is f(x)=0.
