Answer:
138 square centimeters
Step-by-step explanation:
You can find the area by splitting up the shape into pieces and adding it all together, and you get 138 square centimeters.
1,2,4,6,8,10,12,14,16,18,20
Answer:
Step-by-step explanation:
In this problem we have a exponential equation of the form
where
y is the population of the city
x is the number of years
a is the initial value or y-intercept
b is the base
r is the rate of growth
b=(1+r)
we have
substitute
For x=17 years
substitute the value of x in the exponential equation and solve for y
In a direct variation relationship the values must satisfy that y = kx. This si y is always a constant value (k) times x.
So, you can find multiple values that meet this:
y = kx => k = y / x = 11 / 18
=> y = (11/18)x
Now you can give any value to x and fint the value of x that satisfy the relationship:
x y = (11/18)x
1 11/18
2 11/18 * 2 = 11/9
18 11/18 * 18 = 11
36 11/18 * 36 = 22
So, there you have several additional values for x and y in the same relationship that y = 11 and x = 18, and you can find many more using the same rule: y = (11/18)*x
