Answer: 11.1 m
Step-by-step explanation:
This can be solved by the Pythagorean theorem where;
c² = a² + b²
c is the hypotenuse which is the distance from the top of the building to the tip of the shadow.
a is the height
c is the length
32² = 30² + b²
b² = 32² - 30²
b² = 1,024 - 900
b² = 124
b = √124
b = 11.1 m

4x+2y=16
4(-1/2y+4)+2y=16
all real numbers are solutions
Answer:
y= -4x+4
Step-by-step explanation:
so the slope is -4x
