Answer:
x intercept (36, 0)
y intercept (0, 9)
Step-by-step explanation:
x intercept when y = 0 so x = 36
y intercept when x = 0 so 4y = 36; y = 9
Answer
x intercept (36, 0)
y intercept (0, 9)
To solve for its area, we can break the figure apart.
If we splice the figure horizontally, we get a rectangle that is 30 inches long and 18 inches wide and a rectangle that is 30 inches wide and 10 inches in length.
If we solve for the two rectangles separately, we can add them to get the total area of this figure.
The area of rectangle a is 540 sq inches because 30 x 18 = 540.
The area of rectangle b is 300 sq inches because 30 x 10 = 300.
300 + 540 = 840.
The area of this figure is 840 square inches.
Hope this helps! Have an awesome day :)
Answer:
exponential decay
Step-by-step explanation:
The function is in the form
y = ab^x where a is the initial value and b is the growth or decay rate
If b >1 then it is growth
b < 1 then it is decay
f(x) = 5(2/3)^x
a = 5
b = 2/3
2/3 <1 so it is decay
Answer:
The correct answer is 2030.
Step-by-step explanation:
To start we must analyze the information we have.
We know that a city has 8000 inhabitants and that each year this number increases by 0.5%. That means that <u>each year it has 40 more inhabitants</u>:
(8000 . 0,5) : 100 = 40
Having this information we could do a cross multiplication:
1 year ------- 40 inhabitants
x years ------- 81200
81200 = 40.x
x = 81200 : 40
x = 2030
In this way we can verify that the correct answer is 2030.
