Answer:
a. 0.81
b. v = 28000(0.81^n)
c. 2757.36
Step-by-step explanation:
a. The growth factor is 1 more than the growth rate. Here, the growth rate is -19% (per year), so the growth factor, the multiplier, is ...
1 -0.19 = 0.81
__
b. The equation sets value equal to the original value multiplied by the growth factor to the power of the number of years:
value = (original value) × (growth factor)^n
v = 28000(0.81^n)
__
c. For n=11, this is ...
v = 28000(0.81^11) ≈ 2757.36
The value of the truck after 11 years is about $2757.

17. The current low temperature in uxbridge is 18 degrees Fahrenheit. Over the next two days the low temperature will decrease 12 degrees and increase 7 degrees. Express the temperature changes in a numerical expression and say what the temperature will be after three days.
Numerical expression:
Answer:
Answers
Answer:
Expression: 18 - 12 + 7. In 3 days, the temperature will be 13 degrees.
Step-by-step explanation:
The temperature is 18 degrees.
It will decrease 12 degrees after one day. So, it is 18 - 12.
Then it will increase by 7 degrees after another day. So, it is 18 - 12 + 7.
18 - 12 = 6. 6 + 7 = 13.
So, the expression is 18 - 12 + 7 and the answer is 13 degrees (i think)

Solve 6x+3y=−1 for y
Answers
y=-2x-1/3 is the answer
The sets X and Y exists collectively referred to as the function's domain and codomain, respectively.
If the function be 6x + 3y = −1 then the value of y = (−1 - 6x) / 3.
What is meant by function?A function in mathematics from a set X to a set Y assigns exactly one element of Y to each element of X. The sets X and Y exists collectively referred to as the function's domain and codomain, respectively.
The characteristic that every input is associated to exactly one output defines a function as a relationship between a set of inputs and a set of allowable outputs.
A mathematical phrase, rule, or law establishes the link between an independent variable and a dependent variable (the dependent variable).
Let the given function be 6x + 3y = −1.
⇒ 3y = −1 - 6x
simplifying the above equation, we get
⇒ y = (−1 - 6x) / 3
Therefore, the value of y = (−1 - 6x) / 3.

Answers
Answer:

Step-by-step explanation:
The explicit formula is aₙ = -6 · 2⁽ⁿ⁻¹⁾, and we want to find the 9th term in the sequence. To find it, we can simply substitute n = 9 into the explicit formula, which gives us:
a₉ = -6 · 2⁽⁹⁻¹⁾
