For this case, we can model the problem as a triangle with a right angle.
Where,
x, y: lengths of the sides of the triangle
d: hypotenuse of the triangle
We then have the following relationship:

Clearing d we have:
Answer:
A functions that would best model the situation above is:
D square root
Answer:
-10, -1, 5
Step-by-step explanation:
To find the zeros of a function, you have to set each factor to zero in equations, then solve for x ....
x + 10 = 0 ... then factor 10 over (subtract 10 from each side) ...
x = -10
x-5=0
then repeat (add 5 to both sides) (and subtract 1 from both sides) ...
x -5 = 0 to x = 5
x + 1 = 0 to x = -1
hope this helps!! tell me if it doesnt make sense and i can help you!! also if it is right can i have brainliest :) no worries though happy to help
Answer:
None of the expression are equivalent to 
Step-by-step explanation:
Given

Required
Find its equivalents
We start by expanding the given expression

Expand 49


Using laws of indices: 


This implies that; each of the following options A,B and C must be equivalent to
or alternatively, 
A. 
Using law of indices which states;

Applying this law to the numerator; we have

Expand expression in bracket


Also; Using law of indices which states;

becomes

This is not equivalent to 
B. 
Expand numerator


Using law of indices which states;

Applying this law to the numerator; we have


Also; Using law of indices which states;

= 
This is also not equivalent to 
C. 



Using law of indices which states;


This is also not equivalent to 
9 - 6 = 3
so 3 + 6 = 9 which is an addition equation that helps you find the answer.
