Answer:
-3/2
Step-by-step explanation:
the constant of variation is commonly known as <em>k .</em>
<em />
y/x= <em>k</em>
<em />
so -3/2 is your answer
It starts at $500, then decreases by 30% so just multiply 500 by .7, then multiply the answer by .7, and so on until you get to $84.
Answer:
Chords and secants intersect the perimeter of a circle twice. Chords are segments entirely within a circle, while secants are lines or rays that extend through a circle.
Explanation:
A line intersecting a circle in two places is referred to as a secant. The portion of the secant contained within the circle is called a chord.
This means that both chords and secants intersect the perimeter of a circle twice, chords are entirely inside the circle, and secants extend through a circle to the outside.
Answer:
h = 2.7 m
Step-by-step explanation:
ΔADE and ΔABC are similar, hence ratios of corresponding sides are equal
DE / BC = AD / AB, that is
h / 0.9 = 18 / 6 ( cross- multiply )
6h = 16.2 ( divide both sides by 6 )
h = 2.7
