A manufacturer producing a new product, estimates the annual sales to be 9,600 units. Each year, 8% of the units that have been
Crazy boy [7]

Answer:

After n years, 120,000(1 - 0.92ⁿ) units, will be in use.

Step-by-step explanation:

Given;

estimated annual sales, a = 9600 units

determine common ratio, r;

r = 1 - \frac{8}{100}\\\\r = 0.92

sum of the units in use after n years is calculated by applying sum of nth term;

S_n = \frac{a}{1-r} (1-r^n)

S_n = \frac{9600}{1-0.92} (1-0.92^n)\\\\S_n = \frac{9600}{0.08} (1-0.92^n)\\\\S_n = 120,000(1-0.92^n) \ units

Therefore, after n years, 120,000(1 - 0.92ⁿ) units, will be in use.

The temperature at a state park for one day in June can be approximated by the function T(x) = 0.264x2 - 4.752x + 81 0 ≤ x ≤ 18
Lilit [14]

Answer:

  60 °F

Step-by-step explanation:

The function can be put into vertex form:

  T(x) = 0.264(x² -18x) +81 . . . . factor the leading coefficient from 1st 2 terms

Now, we add the square of half the x-coefficient inside parentheses and subtract the same quantity outside parentheses.

  T(x) = 0.264(x² -18x +81) +81 -0.264·81

  T(x) = 0.264(x -9)² +59.616

The low temperature for the day was approximately 59.6 °F, which rounds to 60 °F.
