Answer:
y= -2x
Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.
Given that the slope is -2, m= -2.
subst. m= -2 into the equation:
y= -2x +c
To find the value of c, substitute a coordinate.
When x= -4, y=8,
8= -2(-4) +c
8= 8 +c (expand)
c= 8-8 (-8 on both sides)
c=0 (simplify)
Thus, the equation of the line is y= -2x.
Answer:
33.51
Step-by-step explanation:
There's a formula using the value of the angle but I don't remember it so the most easy way is:
A circle has an angle of 360°
so our section has an angle of 60
and we know that 360=60*6
so the area of the circle we divide it by 6 and we get the area we want
divide this by 6
units squared
1 (877) 275-7673
Call this number i had the same question a few days ago and they helped me alot
Use pythagorean theorem;
a²+b²=c² where a and b are the legs and c is the hypotenuse of triangle
5²+b²=10²
b²=100-25
b²=75
b=√75
b=8.66 miles
Hope I helped :)
