Answer:
A.
Step-by-step explanation:
We have x in exponent, so it is an exponential function.
Exponent is negative, so is is an exponential decay.
For this case we can make the following rule of three:
1 square mile -------------------> 4.6 * 10 ^ 4 pieces of trash
1.2 * 10 ^ 8 square miles -------> x
From here, we clear the value of x:
We have then:
x = (1.2 * 10 ^ 8) * (4.6 * 10 ^ 4)
x = 5.52 * 10 ^ 12 pieces of trash
Answer:
there are 5.52 * 10 ^ 12 pieces of trash in the earth's oceans

Answer:
9 units²
Step-by-step explanation:
This is a trapezium.
The length of the two parallel lines (on top and bottom) are 5 units and 1 units.
The height of the trapezium is 3 units. Using these information, we can apply the formula for area of trapezium to find the answer.
Area = 1/2 (5 + 1) x 3 = 9 units²
