Answer: A = 4 P = π PS = -π/2
<u>Step-by-step explanation:</u>
y = A sin(Bx - C) + D where
- A is the amplitude
- Period = 2π/B
- Phase Shift = C/B
- D is the vertical shift
Given: y = -4 sin(2x + π) - 3
- A (amplitude) = 4 <em>the negative sign is a reflection, not amplitude</em>
- B = 2
- C = -π
- D = -3
Amplitude = 4
Answer:
4/3
Step-by-step explanation:
You use Rise over Run.
It <em>runs</em> 3 blocks to the left (+).
It <em>rises</em> 4 blocks up (+).
The numerator factors as (t-8)(t+4), so the whole thing is (t-8)(t+4)/(t-8). Now we can cancel the t-8 AS LONG as t isn't equal to 8, otherwise, we are canceling a zero from both numerator and denominator which is invalid. What is left is t+4.
So your choice was right.
Answer: Ned received 86 Points overall on the test and Ned lost 24 points overall on his test.
Step-by-step explanation: Ned got 19 questions correct and 6 questions incorrect. He as well got 10 bonus points for answering a bonus question correctly. We know each of the questions on the test (excluding the bonus question) is worth 4 points.
If Ned got 19 questions correct that means 19 x 4 = he received 76 points.
If Ned got 6 questions incorrect that means 6 x 4 = he lost 24 points.
If Ned got 1 question correct that is worth 10 points, that means he got an additional 10 points to his score.
We can add the amount of points Ned scored to the amount of bonus points he earned; 76 + 10 = 86 points total on his test.
