Answers

Step-by-step explanation:

as there are only 3 types of discontinuity overall : A, B and C.

there is no fourth, so D is out.

to check we use x = 2 in both equations and see, if and how the 2 connect or disconnect at that point.

5x + 4, x = 2

5×2 + 4 = 14

this is finite and a well-defined number.

2 - x, x = 2

2 - 2 = 0

this is again finite and well-defined.

but it is different from 14 above.

there is no multiplication factor or so that causes special values. so, there is no removable discontinuity. A is out.

none of the values at the point go to infinity, so there is no infinite discontinuity. B is out.

but yes, the functional value Suendenbock suddenly jumps at the point from 0 to 14 without any connection.

so, yes, it is a jump. C is right.

Answer:

22)43300000, 23)~7, 24)~20

Step-by-step explanation:

22)6.48*10^(7)-(2.15*10^(7))=4.33*10^7 (or 43300000)

23)2.95*10^6=2950000, 2.15*10^7=21500000, 21500000/2950000=~7

24)1.3*10^9=130000000, 1300000000/64800000=~20

Answer:

Step-by-step explanation:

22.  You can write these exponents out if it makes it easier to understand, then convert back into exponential form.

6.48 x 10⁷ = 64800000 France

2.15  x 10⁷ = 21500000  Australia

Subtracting Australia from France = 43300000

Converting back to exponential  would be 4.33 x 10⁷

But if you notice both number have the exponent of 10⁷.  Since these are both the same, you can just subtract the whole number for Australia from the number for France  6.48 - 2.15 = 4.33

then just put the exponent on the end.  4.33 x 10⁷

23.  Again it might be easier to convert to standard numbers first.

Area of Australia = 2.95 x 10⁶  or 2950000

Population = 2.15 x 10⁷  or 21500000

So population per square mile would be population divided by area.

21500000 / 2950000 = 7.3 people per square mile

Now if you look at the two numbers, the exponents are only different by 1.  You can easily make the population have the same exponent as the area by moving the decimal place of the whole number

Population 2.15 x 10⁷ is the exact same as 21.5 x 10⁶.  Now since both number have the same exponents, you can cancel those out and just divide the whole numbers.   21.5 divided by 2.95 which also equals 7.3.

24. You can look at this the same way.

China population 1.3 x 10⁹  is 1300000000

France population 6.48 x 10⁷ is 64800000

Dividing China by France you get about 20.1 which means China is about 20.1 times great in population than France.

If you use the same method as in question 23, you can change the population of China so the exponent matches that of France.

1.3 x 10⁹ is exactly the same as 130 x 10⁷

Again, since both exponents are the same, you can cancel them out and just divide the whole numbers.

130 / 6.48 which also equals about 20.1

A box of cookies contained 40 cookies. Sara and her friends ate 60% of the cookies. How many cookies did Sara and her friends eat? *

Answers

The answer is 24. 40 x 0.6 = 24. Whenever you want to find the percent of something, multiply the total by the percent (in decimal form).
Answer: 24

Step-by-step explanation:

Since Sara and friends ate 60% of the container of cookies, it means that they ate 60% of 40 cookies.

∴

How many cookies Sara and Friends ate = total × (percentage of cookie ate)

                                                                    = 40 × 0.60

                                                                    = 24
