Step-by-step explanation:
I guess we only need to read the details of the already shown line (and don't need to calculate it from the scratch).
usually I am looking for points with integer coordinates to elaborate the equation.
I see here
(0, 2)
(3, 4)
(6, 6)
(9, 8)
the line equation is
y = ax + b
a being the slope, which is "y coordinate change / x coordinate change" when going from one point to another.
and b being the y-intercept (the y value when x = 0).
we know b already from the first point (0, 2) : b = 2.
so, for the slope we use e.g. the first 2 points
(0, 2) and (3, 4)
x changes by +3 (from 0 to 3).
y changes by +2 (from 2 to 4).
so, the slope is +2/+3 = 2/3
and the line equation is
y = 2/3 x + 2
or
y = 2x/3 + 2
Answer:
VT = 50√3 , PT = 50
Step-by-step explanation:
Given
PV = 100
With reference angle 60°
hypotenuse (h) = 100
perpendicular (p) = ?
Now
Sin 60° = p/h
√3 / 2 = p / 100
p = √3 * 100 / 2
p = 50√3
Also
With reference angle 30°
hypotenuse (h) = 100
perpendicular (p) = ?
sin 30° = p/h
1/2 = p / 100
p = 100 / 2
p = 50
Hope it will help :)
Answer:
the answer is 50
Step-by-step explanation:
let the width be x
the length will be x+5
perimeter=2l+2w
=2x+10+2x
4x+10=30
4x=20
x=5(width)
length=5+5=10
area =length*width
area=10*5=50 squared units
