Answer:
P = 10z + 10 units.
Step-by-step explanation:
To find the perimeter of a rectangle, you can use the formula P = 2l + 2w.
If one side is '3z + 2' and the other is '2z + 3', we can plug these into the equation:
P = 2(3z + 2) + 2(2z + 3).
Distributing the 2's gives us:
P = 6z + 4 + 4z + 6
Combine like terms, resulting in the final answer:
P = 10z + 10 units.
Unless you meant -1/2x+2 the top answer is correct. If you meant the other it is -1/2(d/dx(x+2), which results in -1/2(1) or -1/2.
What you must do in this case is to use the potential type function given in the problem:
a (b) ^ x = c
We have:
new car for $ 17,930
a = 17930
The value of the car depreciated by 19% per year
b = 1-0.19 = 0.81
the car is worth no more than $ 1,900
c = 1900
the exponential inequality is:
a (b) ^ x ≤ c
17930 (0.81) ^ x ≤ 1900
Answer:
the exponential inequality is:
17930 (0.81) ^ x ≤ 1900
where
x: number of years
A(-3,5) to B(8,1)
That makes a right triangle 8 - -3 = 11 in the x direction, 5 - 1 = 4 in the y direction.
d² = (8 - -3)² + (1 - 5)² = 11² + (-4)² = 121 + 25 = 146
d = √146 = 12.083045973594572
Answer: 12.1
