Answer:
<h3>
y = -0.1x - 3.4</h3>
Step-by-step explanation:
The point-slope form of equation of a line is:
y - y₀ = m(x - x₀)
where <em>(x₀, y₀)</em> is the point which the line passes through and <em>m</em> is the slope of the line
The product of slopes of two perpendicular lines is -1
so if given lines slope is 10 them:
10·m = -1
m = -0.1
(6, -4) ⇒ x₀ = 6, y₀ = -4
Therefore:
y - (-4) = -0.1(x - 6)
y = -0.1x + 0.6 + (-4)
<u> </u><u>y = -0.1x - 3.4 </u>

Answer:
50.3 ft
Step-by-step explanation:
circumference = 2nr
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
radius = 16/2 = 8
2 x 22/7 x 8 = 50.3ft
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
