Answer:
k = 1
Step-by-step explanation:
=> y ∝ x²
So, y = kx² ----------------------------(1)
<u><em>Where k is the constant of proportionality</em></u>
Now,
y = 9 when x = 3
Putting in (1)
=> 9 = k(3)²
=> 9 = k(9)
Dividing both sides by 9
=> k = 1
Answer:
Step-by-step explanation:
For this exercise you need to use the following formula for calculate the area of the sector of a circle:
Where is the radius of the circle and is the central angle measured in radians.
In this case, you can identify that:
Then, you must substitute theses values into the formula and then you must evaluate, in order to calculate the area of the sector of the circle.
This is:
To answer this item, we let x be the number of counters that Max has. By the representation, the number of counters that Jack has is 3x.
a. Ratio of counters,
3x:x
which can be simplified by dividing by x both sides of the ratio giving us the answer of,
3:1
b. Fraction of counters Max have,
fraction = x / (x + 3x) = 1/4
