After 4 days, a bookstore has 140 copies of a new title still on hand. After 9 days, the bookstore has 50 copies still on hand.
alexira [117]

Answer:

c(t) =-18t +212

Step-by-step explanation:

Given

(t_1,c_1) = (4,140)

(t_2,c_2) = (9,50)

Required

Determine the equation

First, we calculate the slope (m)

m = \frac{c_2 - c_1}{t_2 - t_1}

m = \frac{50 - 140}{9-4}

m = \frac{-90}{5}

m = -18

The equation is then calculated as:

c =m(t - t_1) + c_1

c =-18*(t - 4) + 140

c =-18t +72 + 140

c =-18t +212

Hence, the function is:

c(t) =-18t +212

Use the numbers 8, 6, and 2 and one operation to write and expression that includes an exponent and has a value of 8. Use each n
Vesnalui [34]

Answer:

6+2^{1}=8 \Rightarrow 6+2=8 \Rightarrow 8=8

Step-by-step explanation:

1) One solution is to write, as our exponent:

2^{1}=2

2) Because this is special case of the Exponents Law, valid for every base ≠ 0.

a^{1}=a

3) Hence, including an exponent the numbers 6, 2 whose value is eight.

6+2^{1}=8 \Rightarrow 6+2=8 \Rightarrow 8=8

Therefore our expression is true
