How to solve it the the composite area

1 answer:

6 0

Area of the bottom square part is 10 x 14 = 140 square mm

area of the top rounded part is half a circle
area of a circle = PI x r^2
r = 14/2 = 7
area = 3.14 x 7^2 = 153.86

1/2 circle = 153.86 / 2 = 76.93

total area = 140 + 76.98 = 216.93 square mm

There were 800 farmers' markets initially in the USA in 2012. In 2013, the number of farmers' markets was 1.25 times the initial

For this case we have a function of the form:
$y = A * (b) ^ x
$
Where,
A: it is the initial amount
b: is the growth rate
x: is the number of years
Substituting values we have:
$y = 800 * (1.25) ^ x$
We have a growing exponential function because the value of b is greater than 1.
