The number of bacteria present in a culture after t minutes is given as where k is a constant. if there are 8520 bacteria presen
andrew-mc [135]
Given that the situation has been modeled by the formula:
B=1000e^(kt)
given that B=8520 after t=15 min
then the value of k will be solved as follows:
plugging in the values in the formula and solving for k
8520=1000e^(15k)
8.52=e^(15k)
solving for k
15k=ln(8.52)
hence
k=ln(8.52)/15
k=0.1428
k=0.143

Frank got a gift for his sister and put it in a shoebox.
Leona [35]

Answer:

The correct answer is option C.

Step-by-step explanation:

Length of shoe box = l = 11 inches

Width of the shoes box = w = 6 inches

Height of the shoe box = h = 5 inches

Wrapping paper required t cover the shoe box will be equal to the total surface area of the shoe box.

Shoe box = Cuboid

Total surface area of the cuboid = 2(lw+wh+hl)

Total surface area of shoe box : T

T=2\times (11 inch\times 6 inch+6 inch\times 5 inch+5 inch\times 11 inch)

=T = 302 inch^2

Frank will need 302 square inches of wrapping paper to cover the shoe box.
