Answer:
(0,4) vertex and (1,3) another pt
Step-by-step explanation:
The parabola has been shifted up 4 units from parent function (there is also a reflection)...but we only really care about the shift 4 units up from (0,0) for our vertex... Our vertex is (0,4)
Now just plug in another number to find another point...let's do x=1
Plug in you get -1^2+4=-1+4=3 so another point is (1,3)
Answer:
Step-by-step explanation:
A) Initial amount deposited into the account is $675 This means that the principal,
P = 500
It was compounded twice in a year. This means that
n = 1
The rate at which the principal was compounded is 3.4%. So
r = 3.4/100 = 0.034
It was compounded for t years
The formula for compound interest is
A = P(1+r/n)^nt
A = total amount in the account at the end of t years. Therefore, the function that represents this situation would be
A = 675(1 + 0.034/2)^ 2 × t
A = 675(1.017)^2t
B) at t = 2.5,
A = 675(1.017)^2 × 2.5
A = 675(1.017)^5
A = $734.36
Answer:
-2.64

Answer:
x approximately = 31.22
Step-by-step explanation:
1.29 + 1.56x = 50
- 1.29 - 1.29
_________________
1.56x = 48.71
___________
1.56
x approximately = 31.22
Hope this helps at all!
The answer is the first row.
Explanation:
8 * 10^7 = 80,000,000 -- 2 * 10^4 = 20,000
80,000,000 divided by 20,000 = 4,000, so it is 4,000 times larger
Therefore, the first answer is correct.
Hope I helped and good luck!
