Answer:
2nd option
Step-by-step explanation:
Given
2x - 8y + 3x² + 7y - 12x ← collect like terms
= 3x² + (2x - 12x) + (- 8y + 7y)
= 3x² + (- 10x) + (- y)
= 3x² - 10x - y
The trigonometric identity can be used to solve for the height of the blue ladder that is leaning against the building is
.
We have to determine
Which trigonometric identity can be used to solve for the height of the blue ladder that is leaning against the building?.
<h3>Trigonometric identity</h3>
Trigonometric Identities are the equalities that involve trigonometry functions and hold true for all the values of variables given in the equation.
Trig ratios help us calculate side lengths and interior angles of right triangles:
The trigonometric identity that can be used to solve for the height of the blue ladder is;

Hence, the trigonometric identity can be used to solve for the height of the blue ladder that is leaning against the building is

Answer:
Option C is the answer.
Step-by-step explanation:
To find the equation of the straight line equation i.e, we must be given with the two points
and 
Since from the graph the two points closest to the line are
and 
Equation of line with two points closest to the line :

where m is the slope.
First we find the slope(m)=

on simplify we get,
.
Now, to find the equation of the line: 

Apply distributive property on right hand side, we get
Adding both sides by 36, we get

.
The equation for the linear model in the scatter plot obtained by the two closest point
closest to the line is,

Answer is 9r
