As we can see on the picture we have a rectangle and half of circle.
The areas for half circle and rectangle are:
The area of the figure is the sum of the area of half circle and rectangle. Also the height of a rectangle (6ft) is a diameter of a half circle therefore the radius of half circle is 6ft ÷ 2 = 3ft.
Now we calculate the areas.
The area of the figure is approximately 74ft squared.
Hope this helps.

Answer:
-600
Step-by-step explanation:
The rate of change of a function f(x) in a certain interval is the ratio between the change of the function and the change in the value of x:
The rate of change of a function tells how much the value of the function is changing per change in unit of x: therefore, for a linear function it corresponds to the slope of the line.
In this problem, the function f(x) is equal to the value of the business machine in dollars, while the variable x represents the number of years.
Here we are told that the machine was purchased for
while its value decreases by $600 each year, so
This means that the linear function that represents the value of the machine after x years is:
Therefore, the rate of change of the function is -600.
The probability that Pete exceeds 200 in at least 9 of his next 10 games is 0.268+0.1074 = 0.3754
<h3>What is Probability ?</h3>Probability is defined as the likeliness of an event to happen.
It has a range of 0 to 1.
It is given that
Pete, a professional bowler, is unhappy with any game below 200
80% of his games exceed this score.
the probability that Pete exceeds 200 in at least 9 of his next 10 games is given by
P( 9/10 > 200) +P(10/10>200)
The binomial experiment consists of n trial out of it x is success.
Here p = 0.8
For 9/10 matches
For (10/10 >200)
Therefore the probability that Pete exceeds 200 in at least 9 of his next 10 games is 0.268+0.1074 = 0.3754.
