The equation is y=34000(1-0.06)ˣ.
It will take nearly 8 years for the car to lose enough value to be worth less than $21,000.
Using 21,000 for y, we have
21000=34000(1-0.06)ˣ
21000=34000(0.94)ˣ
Dividing both sides by 34000:
21000/34000 = 34000(0.94)ˣ/34000
(21/34) = 0.94ˣ
Using logarithms to solve this,
Answer:
<u>45°</u>
Step-by-step explanation:
From the diagram :
- ∠AOC = ∠AOB + ∠BOC
- 96 = 9x - 75 + 8x - 67
- 17x - 142 = 96
- 17x = 238
- x = 238/17
- x = 14
Finding ∠BOC :
- ∠BOC = 8x - 67
- ∠BOC = 8(14) - 67
- ∠BOC = 112 - 67
- ∠BOC = <u>45°</u>

Answer:
The domain is all real numbers, and the range is all real numbers f(x) such that f(x) ≤ 4. You can check that the vertex is indeed at (1, 4). Since a quadratic function has two mirror image halves, the line of reflection has to be in the middle of two points with the same y value.
X = # adults
y = # children

24x+16y=$10272
x + y =532
