Answer:

Step-by-step explanation:
Calculate the distance d using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 1, 4) and (x₂, y₂ ) = (6, - 2)
d = 
= 
= 
=
← exact distance

Answer:
D) -122
Step-by-step explanation:
Given:

We need to find f(-4).
Now by substituting the value of x =-4 in above equation we get;

By using PEDMAS we will solve for exponential function first we get;
Now we know that 
So we get;

Now using PEDMAS we will solve division.

Now using PEDMAS we solve multiplication.

Finally by subtraction we get;

the angles the top part that has a square is 90⁰ and x and y are equal so we will name them both x and all angles together make 180⁰
I don't know about the sides
Step-by-step explanation:
90+x+x=180
2x=180-90
2x=90
x=90/2
x=45
