Answer:
Step-by-step explanation:
Both of these questions involve proportions. You can set up an equation using equivalent fractions. You want to express to ratio of cm to km in Part A. Given the scale factor 5 cm = 2 km, then we can let c = the number of cm that represent an actual distance of 5 km. The following equation can be formed:
5/2 = c/5
Both of these fractions are a ratio of cm to km. To solve, we can cross-multiply.
2c = 25
c = 12.5 cm
You can use a similar process for Part B.
X= 51 is the answer you need to remember that since they share a straight line you add the together to get 180 which is half a circle
Answer:
Step-by-step explanation:
1. Three zeroes equal 1,000
2. One zero equal 10
3. One zero equal 10
4. Look at the value without the zeroes
5. Three zeroes equal 1,000
6. Look at the value without the zeroes
7. Since 890 has one zero, one more zero equal 10
8. Look at the value without the zeroes
9. Same as 8.
10. Three zeroes equal 1,000
11. Look at the value without the zeroes
12. Three zeroes equal 1,000
13. Same as 11.
14. Same as 13.
15. N/A
16. I am not sure about this one cause I don't know if there are more zeroes or not, but same as 13.
A jump discontinuity occurs when the limits as x approaches a number from the left and right are not equal. Basically, the graph "jumps" from one number to another at that x value.
A point discontinuity occurs when limits as x approaches a number from the left and right are equal, but the actual value of f(x) at x is not equal to the limit. Basically, a point is missing and there is a "hole" in the graph at that x value.
Looking at your graph, you can see that at x=0, the graph "jumps" from a value of 2 as the graph approaches x=0 from the left to a value of 1 as the graph approaches x=0 from the right. That means there is a jump discontinuity at x=0.
You can also see that there is a "hole" in the graph at x=-2 and x=8 as seen by the open circle. There is no hole at x=3 because the circle is filled in. That means there is a point discontinuity at x=-2 and x=8.
Your answer is B) jump discontinuity at x=0; point discontinuities at x=-2 and x=8.
Answer and explanation:
Keira could get or look up an electronic copy of the book online. Once she has an electronic copy(pdf for instance) of the book, she can count number of e's in her book using the PDF reader or any software extension(good number of tools online) that would do just that.
Factors for Keira to consider:
How many lines and words are there on average per page; how many words are there per line?
How many e's are there manually counting for at least 5 pages.
Problems Keira might have in collecting data:
If book is physical and not an electronic copy, Keira may have to go through a tedious task of counting manually. She could make a rough estimation based on a few pages counted but she would need more accurate figures which requires the tedious task of counting e 's manually
