Answer:

Step-by-step explanation:
1. take out constants
( 5 × 2 × 4 × - 4 × - 2) 
2. simplify 5 × 2 to 10
(10 × 4 - 4 × - 2)
3. simplify 10 × 4 to 40
(40 × - 4 × - 2)
4. simplify 40 × -4 to -160
(-160 × - 2)
5. simplify -160 × -2 to 320

6. use product rule:

7. simplify 5 + 5 to 10

8. simplify 10 + 5 to 15 
For the answer to the question above,
<span>V(n) = a * b^n, where V(n) shows the value of boat after n years.
V(0) = 3500
V(2) = 2000
n = 0
V(0) = a * b^0 = 3500
a = 3500
V(2) = a * b^2
2000 = 3500 * b^2
b = sqrt (2000/3500)
b ≈ 0.76
V(n) = 3500 * 0.76^n
We can check it for n = 1 which is close to 2500 in the graph:
V(1) = 3500 * (0.76)^1
V(1) = 2660
And in the graph we have V(3) ≈ 1500,
V(n) = 3500 * (0.76)^3 ≈ 1536
Now n = 9.5
V(9.5) = 3500 * (0.76)^(9.5)
V(9.5) ≈ 258</span>
Answer:

Step-by-step explanation:

3x+4y=12
4y = - 3x + 12
y = -3/4 x + 3; This line has slope equal - 3/4
Perpendicular lines, slope is opposite and reciprocal so slope of new line = 4/3
Passing point (6 , -2)
y + 2 = 4/3(x - 6)
y + 2 = 4/3 x - 8
y = 4/3 x - 10
Answer
Equation: y = 4/3 x - 10
Answer:
5.30
Step-by-step explanation:
11.58 + 3.14 = 14.72
20 - 14.72 = 5.28
nearest dime is 5.30
