Switch the parts on the right where it says “Multiplication property” and “subtraction property”
Y=-1/2x+3
y=-1/2x-5 is parallel:
y=-1/2x-1 is parallel: x+2y=-2
y=2x-4 is perpendicular: -2x+y=-4
y=1/2x+2 is parallel: -x+2y=2
Answer:
The linear regression model is
.
Step-by-step explanation:
The given data points are (-6 4) (-4 0) (-3 -2) (-1 -7). Plot these points on a coordinate plane.
From the graph it is clear that the point are in the form of a straight line, so we need to use the linear regression model.
The general linear regression model is

Using technology we get


Put a=-2.19 and b=-8.92 in the above equation.

Therefore the linear regression model is
.
Sin(72°)=x÷20ft.
sin(72°)×20ft.= 19ft 252 inches
the ladder reach 19ft 252 inches tall on the building.
The answer is B. Parabola is a symmetrical open plane bend framed by the crossing point of a cone with a plane parallel to its side. The way of a shot affected by gravity in a perfect world takes after a bend of this shape.
