Answer:
see the explanation
Step-by-step explanation:
we know that
The y-intercept is the value of the function when the value of x is equal to zero. Also is called the initial value of the function
I will analyze two cases
Part 1) we have

so
For x=0
substitute

therefore
The y-intercept is the point (0,0)
Part 2) we have

so
For x=0
substitute

therefore
The y-intercept is the point (0,-1)
4 times x minus 8 is the answer
The answer is 1,728,because you multiply 36 nd 18
Answer:
Step-by-step explanation:
sec (-x)-sin (-x) tan (-x)=cos x
sec(x)-(-sin x)(-tan x)=cos x
1/cos x-sin x(sin x/cos x)=cos x
multiply by cos x
1-sin ²x=cos²x
or 1=sin²x+cos²x
which is true.
The correct notation for the
is -84+10i.
Answer: Option B.
<u>Step-by-step explanation:</u>
A square root is the inverse function of exponential function.
Square root of positive numbers either result natural numbers or rational numbers.
But the square root of negative number is not possible. So that an imaginary number system was founded to represent the square root of negative number.
It is represented with i with the result of the solution of the square root.
Here the given problem is
,
-84 will remain the same and let us convert
.
can be written as
×
.
= 10
= i.
∴
=10i.
The correct notation for the
is -84+10i
