Jenny studied the characteristics of two species of bacteria. The number of bacteria of species A, A(t), after t hours is repres

fredd [130]

Answer: D . $N(t) = 3 + (0.25t)^3 - 8(1.06)^t$

Step-by-step explanation:

Given : Jenny studied the characteristics of two species of bacteria. The number of bacteria of species A, A(t), after t hours is represented by the function,

$A(t) = 5 + (0.25t)^3$

The number of bacteria of species B, B(t), after t hours is represented by the function, $B(t) = 2 + 8(1.06)^t$

Then, the difference in the number of bacteria, N(t), of both the species after t hours will be :-

$N(t)=A(t)-B(t)\\\\=5 + (0.25t)^3-(2 + 8(1.06)^t)\\\\=5 + (0.25t)^3-2-8(1.06)^t\\\\=5-2 +(0.25t)^3-8(1.06)^t\\\\=3+(0.25t)^3-8(1.06)^t$

Hence, the correct answer should be : D . $N(t) = 3 + (0.25t)^3 - 8(1.06)^t$

Write a two-column proof. Given: Quadrilateral ABCD is a parallelogram; M is a midpoint of Segment AB; N is a midpoint of Segmen

Zigmanuir [339]

Answer:

The answer is given below

Step-by-step explanation:

Statement Reasons

ABCD is a parallelogram; M is a midpoint Given

of AB and N is a midpoint of Segment

AB//DC, therefore AM//NC For a parallelogram, opposite . sides are parallel to each other

AB≅DC For a parallelogram, opposite . sides are equal to each other

1/2AB≅1/2DC Since both sides are equal to . each other

1/2AB = AM and 1/2DC = NC M is the midpoint of AB and N . is the midpoint of DC Midpoint

. theorem

AM≅NC Substitution, since AB is also

. equal to BC

Quadrilateral AMCN is a parallelogram If opposite sides of a

. quadrilateral is equal and .

opposite, it is a parallelogram
