Answer:
Option (D).
Step-by-step explanation:
Initial population of the deer 
= 4800
Decrease in the population of the deer after every 8 years = 
Decrease in population is an exponential process, so the expression representing population will be,
Where 
is the population after 'x' slots of 8 years.
r = fraction of decrease in the population
x = 
By substituting the values of r and x in the expression,
Therefore, Sylvia should do few corrections in her expression.
(8) should be replaced by (
) and 
should be replaced by 
.
Option D. will be the answer.
To answer question 12, you first need to know the definition of a <em>prism</em> and a<em> pyramid.
</em>A <em>pyramid </em> is a 3-D structure with one base, whose outer faces are made of triangles, and meet at a single point at the top.
A <em>prism</em> is any 3-D shape with a base of any number of sides, another base with the same amount of sides, and faces joining the two together on every side of the bases.
12.
Shape A is a <em>pyramid</em>, because it has one base, and all the faces join together in at one point.
Shape B is a <em>prism</em>, because it has two bases, and faces joining every side of the bases.
Shape C is a <em>prism.</em>
Shape D is a <em>pyramid.
</em>For #13, you have to know the definition of a cube to figure out the math of how many cubes there are.
A cube is a 3-D shape with six sides, all made up of squares of the same size.
The box has a volume of 120 cubic inches, and each cube is 1 inch. Since every side of a cube is equal, a 1-inch cube is one cubic inch.
This means that a box with a volume of 120 cubic inches will fit 120 of the 1 inch cubes.
1 layer of the cubes, in the diagram, is 8 cubes by 3 cubes, or 24 cubes total.
To find the number of layers needed to fill the box, you divide 120 by 24.
120 ÷ 24 = 5
The answer to #13 is 5 layers.
3x+3=9
x=2
that way the answer is 9
Substract 6 to both sides and you get 36 =-2d then you use the multiplicative inverse and d=-18.
