Step-by-step explanation:
A₁ = 1; r=1.5
a₉ = a₁ * r⁸ = 1 * 1.5⁸ ≈ 25.63
Answer: c. 25.63
Answer: 6
Step-by-step explanation: you make a number line or you can start on your left from -15,-14,-13,-12,-11,-10,-9, you “hop” 6 times on a number line to get to -9
Here we have to use the fact that the domain of the function is equal to the range of the inverse function and range of the function is equal to the domain of the inverse function .
Here the domain of the function is given. It means, the range of the function is same .
SO the correct option is the third option .
Answer:
so we get as,
let, y = 2 - 9i
so the absolute value is |y|
so we get as,
|y| =
2-9i
so the absolute value is |y|
|y|=√
2 to the 2nd power plus 9 to the second power
so we get as,
|y|=
√81+4=√85
so the value is √85
