Answer:
Step-by-step explanation:
The common ratio is the constant found by dividing any term by the previous term.
r=6/36=1/6
r=1/6
I am assuming the 16 at the end of the sequence was a typo. IF 16 was at the end of the sequence it is NOT a geometric sequence as there would not be a common ratio for all terms.
Answer:
f-1(x) = (x - 1)/ 5.
Step-by-step explanation:
Lete f(x) = y = 5x + 1
Now we find an expression for x in terms of y:
y = 5x + 1
5x = y - 1
x = (y - 1) / 5
So the inverse of th function = f-1(x) = (x - 1)/ 5 (answer).
Answer:
Take the circumference of the circle and divide by two times pi for circle with a circumference of 15 you should divide by 15 by 2×3.14 and round the decimal point to your answer of approximately 2.39
Step-by-step explanation:
If the weight of the little brother is x, then the weight of Charles is x + 9
The equation that can be used to determine what each one weighs is:
x + (x + 9) = 99.
Let us now solve it.
x + x +9 = 99
2x + 9 = 99
2x = 99 - 9
2x = 90
x = 90/2
x = 45
Little brother's weight is 45 kg.
Charles' weight will be 45 + 9 = 54 kg
Adding these two weights will give 99kg
