For the circle we can just do 7.5^2*3.14=176.625 because if you put the 2 semi circle you get a whole circle.
and if the diameter is 15 then the width of the rectangle is 15 so 28*15=420+176.625=596.625
-38+6x evaluate the power calculate the difference
In function notation (f(x)=mx+b) m represents the slope and b represents the y-intercept.
In a straight horizontal line the slope is always 0. This cancels out the 'x' factor so you get f(x)=b.
To find b you simply look at where the line crosses the y-axis. in this case it crosses at 2.
When you plug in the y-intercept you get f(x)=2
Answer:
18. <u>0.25</u>
19. <u>0.33</u>
Step-by-step explanation:
<u>Problem 18</u>
- Number of oranges = 2
- Number of fruits = 2 + 6 = 8
- P (orange) = 2/8 = 1/4
- P (orange) = <u>0.25</u>
<u />
<u>Problem 19</u>
- Number of 1 or 6 faces = 2
- Total faces = 6
- P (1 or 6) = 2/6 = 1/3
- P (1 or 6) = <u>0.33</u> (2 DP)
In this situation, 0 and 6 could be domain values.
The domain is the number of packages that are sold. The only possible values are 0 and 6.
First, the number of packages has to be less than or equal to 12. Second, you can buy negative packages or partial packages.
