Suppose a population of 160 crickets double in size every month. The function f(x)=160*2^x gives the population after to months.
melomori [17]
First, we determine how many months are there in two years. We know that each year has 12 months. With these, there are 24 months in 2 years. Solving for the number of crickets in two months,
                           f(x)  = 160 x (2^24/2)
                                   = 655,360
Therefore, after 2 years there are 655,360 crickets.

A monument in a park is shaped like a square pyramid. The dimensions are shown in the net. What is the surface area of the monum
vampirchik [111]

The surface area of the monument shaped like a square pyramid is 14 m².

<h3>Area </h3>

Area is the amount of space that is occupied by a two dimensional shape or object.

From the diagram

Area of each triangle = (1/2) * base * height = (1/2) * 2 * 2.5 = 2.5 m²

Area of square = length * length = 2 m * 2 m = 4 m²

Surface area of monument = 4(2.5) + 4 = 14 m²

The surface area of the monument shaped like a square pyramid is 14 m².
