No, the first one you did get correct but the second, third and fourth are wrong here is you correct answer.
F(x) = 4x - x to the second power
So you substitute x for the numbers under x.
The second answer under f(x) is wrong it’s suppose to be...
F(x) = 4(0) - 0 to the second power the answer is 0.
The third answer under f(x) is also wrong the answer is...
F(x) = 4(-1) - -1 to the second power the answer is -3.
Looking back I see that under x the number 2 in f(x) is wrong also.
The answer Is f(x) = 4(2) - 2 to the second power equals 4.
Step-by-step explanation:
The midline is the average of the lowest point and the highest point.
y = (4 + 6) / 2
y = 5
The amplitude is the distance from the midline to the lowest/highest point:
a = 5 − 4 = 1, or a = 6 − 5 = 1
It's also half the distance between the lowest point and the highest point:
a = (6 − 4) / 2
a = 1
The period is the time it takes to complete a full cycle, so the period is 12 hours.
Step 1:
Cost * Markup= $ Markup
=$20 * 15%
=20 * 0.15
=$3.00 markup
Step 2:
Cost + $ Markup= Selling Price
$20 + $3 = $23.00
Selling Price= $23.00
Hope this helped :)
Answer:
It seems he does not treasure your friendship the same as you
Step-by-step explanation:
It sounds like he doesn't see you as an actually friend, I'd say drop him. Friends at least support each other, it's not only one way. It's unfair for u to support him but he isn't willing to do the same, even if someone is not good at comforting, the least they could do is listen. So you should confront him about it, but if he makes some excuse that seems off, I'd suggest cutting off that friendship, you could do and deserve an actual friend.
