Apassenger car weighs 4.5x10³ units. which unit of measure was used? grams ounces pounds tons

pounds

Step-by-step explanation:

10³ = 10(10)(10) = 1000

4.5(1000) = 4500

4500 grams would be much too small for a car.

4500 tons would be 4500(2000) = 9000000 pounds; this would be much too large for a car.

4500 ounces would be much too small for a car.

4500 pounds, however, is about the right size for a car.

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
