Answer:
Your answer is going to in Exact Form 15/4
Decimal form 3.75
Mixed number is 3 3/4
Step-by-step explanation: Welcome
Its an absurd decimal, which I'm pretty sure you don't want but will give to you anyway. Its roughly 0.02631578947...
Answer:
Given Exponential Function is :
We have check which graph represent given Exponential Function,
let, 
Put x = 0, we get
y = 5 × 1 - 1 = 4
One of the passing through point = ( 0 , 4 )
Now, Put y = 0, we get
x = -1.465
Another passing through point is ( -1.465 , 0 )
So, Clearly No Given Option in attached is correct.
Correct Graph is attached.

Answer:
±90
Step-by-step explanation:
√(-225) · √(-36) = (15i)·(6i) = 90i² = 90·(-1) = -90
_____
On the other hand, ...
... √(-225) · √(-36) = √((-225)·(-36)) = √8100 = 90
___
If you consider all the roots at each stage, the result is ±90. Since you're working with complex numbers here, it is reasonable to recognize every number has two square roots.
... √(-225) = ±15i
... √(-36) = ±6i
... √(-225) · √(-36) = (±15i)·(±6i) = ±90i² = ±90
