Answer:
Distance from the point to the line will be 
Step-by-step explanation:
We have given the equation of the line is y = 2x\
So the equation of line will be y-2x = 0
Point from which we have to find the distance is (-2,1)
Distance from a point to line is given by
, here A = -2 , B = 1 and C = 0
And point x = -2 and y = 1
So 
So distance from the point to the line will be 
Answer:
g12. 85 + b4. 79
Step-by-step explanation:
g and b is just the amount she buys
Given that the garden is rectangular and a line of roses form the diagonal 18.4 m long, we required to calculate the length of the perpendicular side.
Here we shall use the Pythagorean theorem.
c²=a²+b²
where c is the hypotenuse, a and b are the legs.
from the information given:
c=18.4 m
a=13 m
plugging this into our expression we get:
18.4²=13²+b²
next we solve for the value of b
b²=18.4²-13²
b²=338.56-169
b²=169.56
b=√169.56
b=13.0215
hence the length to the nearest tenth of a meter will be approximately 13.0 m
