Given series is 2.4,-4.8,9.6,-19.2
To find whether it has common difference or common ratio let us find few differences and few ratios of consecutive terms.
Common difference of first 2 terms = 2nd term - first term = -4.8-2.4 = -7.2
Common difference of 2nd and 3rd terms = 3rd term - 2nd term = 9.6-(-4.8) = 14.4
Since those common differences are not equal the given series does not have common difference at all.
To check if it has common ratio or not let us find few ratios of consecutive terms.
Common ratio of first 2 terms = =
Common ratio of 2nd and 3rd terms =
So, the given series has common ratio as -2.0
Answer:
169 cm²
Step-by-step explanation:
Recall that the area of the largest square is |PR|²
Also recall from Pythagoras Theorem that:
|PQ|² +|QR|² =|PR|² ---->1
Also we have that the sum of the areas of the three squares is 338 square centimeters.
This implies that:
|PQ|² +|QR|² +|PR|²=338---->2
Put equation (1) into (2)
|PR|²+|PR|²=338
Simplify to get:
2|PR|²=338
Divide both sides by 2 to get:
|PR|²=338
|PR|²=169

Answer:
Step-by-step explanation:
The number of miles is directly proportional to the amount of gas, then:
Where the amount can be modelled as the product of the maximum amount of gas and the percentage of occupied capacity. Hence:
Answer:
I would say the answer is 1.5
