A radioactive material has a half life of 10 years. What is the fraction of the initial isotope is left after 60 years

Answers

Answer:

1/64

Step-by-step explanation:

10 = ½

20 = ¼

30 = ⅛

40 = 1/16

50 = 1/32

60 = 1/64

Answer:

0.015625 left.

Step-by-step explanation:

If we start with say 100g of the material, in 10 years there is 100 * 1/2 =

50g left   ( = 0.5 left).

In 20 years there is 100*(1/2)^2 = 25 g  left.

In n*10 years there is  100(1/2)^2 g

So in 60 years there is 100(1/2)^6 = 1.5625 g left

This is 1.5625 %

= 0.015625 of the origin material left.

- greater than or equal to,

- less than,

- less than or equal to between two numbers or algebraic expressions.

We have,

Inequalities where we need to find the coordinates and see which inequalities represent the graph.

y < 4 (x- 1)² - 11 ____(1)

y < -4 (x-1)² - 11 _____(2)

y < 4 (x-1)² - 16 ______(3)

From (1),

y =  4 (x- 1)² - 11

x = 0, y = 4 x 1 - 11 = 4 - 11 = -7

From (2),

y = -4 (x-1)² - 11

y = -4 x 1 - 11 = -4 - 11 = -15

From (3),

y = 4 (x-1)² - 16

x = 0, y = 4 x 1 - 16 = 4 - 16 = -12

We see that,

y < 4 (x-1)² - 16  gives us the coordinates (0, -12) on the graph.

Similarly,

x = 1, y = 4 x 0  - 16 = 0 -16 = -16

x = 1, y = 4 x 1 - 16 = 4 - 16 = -12

(1, -16) and (2, -12) coordinates are on the graph.

Answers

Answer:

  9

Step-by-step explanation:

The 79-digit number of interest can be formulated as a sum of shorter numbers whose remainders can be computed.

Expanded form

The expanded form of the number can be written as ...

  a_44 = 01×10^78 +23×10^76 +45×10^74 +67×10^72 +89×10^70 +...

  +10×10^68 +11×10^66 +... +43×10^2 +44×10^0

Powers of 10

Each number except the last is multiplied by a power of 10. Powers of 10 modulo 45 are ...

  10 mod 45 = 10

  100 mod 45 = 10

This lets us conclude that any positive power of 10 mod 45 is 10.

Parts of the sum

In short, all of the multiplication by powers of 10 can be collapsed to a single multiplication by 10. Hence, the mod 45 value of a_44 will be ...

  a_44 mod 45 = (((01 +23 +45 +67 +89) +10 +11 +12 +... +43)×10 +44) mod 45

  = (((01 +23 +45 +67 +89) mod 45 + sum(10 .. 43) mod 45)×10 +44) mod 45

  = (((225 mod 45) +(901 mod 45))×10 +44) mod 45

  = ((0 +1)×10 +44) mod 45

Final value

  a_44 mod 45 = 54 mod 45 = 9

The surface area of the pyramid is 34.8 in²

How to find the surface area of the figure?

Since the figure is a square pyramid, its surface area, A = 4 × area of triangular face + area of square base.

The area of triangular face

Area of triangular face A' = 1/2bh where

h = height = 4.3 in and b = base = 3 in.

So, A' = 1/2 × 4.3 in × 3 in

A' = 1/2 × 12.9 in²

A' = 6.45 in²

The area of square base

Area of square base A" = L² where L = length of base = 3 in

So, A" = (3 in)²

= 9 in²

The Surface area of pyramid.

Surface area of pyramid, A = 4A' + A"

= 4 × 6.45 in² + 9 in²

A newspaper started an online version of its paper 14 years ago. In a recent presentation to stockholders, the lead marketing executive states that the revenues for online ads have more than doubled that of the revenues for printed ads since starting the online version of the paper. Use the graph below to justify the lead executive’s statement and to determine the approximate year that the two ad revenues were equal.

Answers

The approximate year at which two revenues were equal is; 7.5 years

How to interpret Revenue Graphs?

From the graph attached, we see that in the year 10, the revenue for printed ads was 2 million dollars & 3 million dollars for printed ads and online ads revenue respectively.

Thus, printed ad. Revenue line equation is;

(y - 2) = (3 - 2)(x - 10)/(0 - 10)

y - 2 = (x - 10)/-10

x - 10 = -10(y - 2)

x - 10 = -10y + 20

x - 10 = -10y + 20

x  + 10y = 30   -----(1)

At x = 12 years from the graph, we have;

12 + 10y = 30

10y = 18

y = 1.8

Thus, online ad. Revenue line equation is;

(y - 0) = ((3 - 0)/(10 - 0))(x - 0)

y = 3x/10

10y = 3x

10y - 3x = 0 -----(2)

At x = 12, we have;

10y = 3*12

10y = 36

y = 3.6

In year '12' the online ad revenue got doubled as that of printed ad revenue and afterward more than doubled.

Gauss's method

General formula for the sum of the first n integers:

[tex]1+2+3+ \dots +n=\dfrac{1}{2}n(n+1)[/tex]

Question 43

Given sum:  

1 + 2 + 3 + ... + 200

Therefore, n = 200.

Substitute the value of n into the formula:

[tex]\implies \dfrac{1}{2}(200)(200+1)=100 \cdot 201=20100[/tex]

Question 44

Given sum:  

1 + 2 + 3 + ... + 400

Therefore, n = 400.

Substitute the value of n into the formula:

[tex]\implies \dfrac{1}{2}(400)(400+1)=200 \cdot 401=80200[/tex]

Question 45

Given sum:  

1 + 2 + 3 + ... + 800

Therefore, n = 800.

Substitute the value of n into the formula:

[tex]\implies \dfrac{1}{2}(800)(800+1)=400 \cdot 801 =320400[/tex]

Question 46

Given sum:  

1 + 2 + 3 + ... + 2000

Therefore, n = 2000.

Substitute the value of n into the formula:

[tex]\implies \dfrac{1}{2}(2000)(2000+1)=1000 \cdot 2001=2001000[/tex]

Jason and Britton are driving to St. George. Jason got a 20 mile head start and drove an
average of 65 mph the entire way. Britton drove an average of 75 mph. After how many
hours and miles will Britton catch up to Jason?

Answers

Answer:

  2 hours, 150 miles

Step-by-step explanation:

The relation between time, speed, and distance can be used to solve this problem. It can work well to consider just the distance between the drivers, and the speed at which that is changing.

Separation distance

Jason got a head start of 20 miles, so that is the initial separation between the two drivers.

Closure speed

Jason is driving 10 mph faster than Britton, so is closing the initial separation gap at that rate.

Closure time

The relevant relation is ...

  time = distance/speed

Then the time it takes to reduce the separation distance to zero is ...

  closure time = separation distance / closure speed = 20 mi / (10 mi/h)

  closure time = 2 h

Britton will catch up to Jason after 2 hours. In that time, Britton will have driven (2 h)(75 mi/h) = 150 miles.

__

Additional comment

The attached graph shows the distance driven as a function of time from when Britton started. The distances will be equal after 2 hours, meaning the drivers are in the same place, 150 miles from their starting spot.

A high school principal conducts a survey on whether or not students would be interested in an elective art course. The principal knows that it would be too time-consuming to survey all 482 students in the high school, so he decides to ask the 98 students currently in the cafeteria. One of the students states that this survey cannot be used to make an inference about the entire high school. Which of the following statements best justifies the student's interpretation of the survey?

The survey sample was too small.

B
An art teacher should have conducted the survey.

C
The survey method was flawed since the sample was not random.

D
An observational study, rather than a sample survey, should have been used.

Answers

The survey method was flawed since the sample was not random.

What is a survey?

A survey is an investigation that is carried out on a sample of a population. However, for the sample to be representative of the population,  care must be taken to pick the participants in the survey at random. The principal ought to have carefully crafted a method in which the sample can be selected in a randomized manner.

For instance, the principal could have decided to take the fifth student in every row in all the classes in the school. In that way, the sample would be adequately randomized hence the result of the survey would be adjudged as representative of the situation in the entire population and thus it will be reliable as a tool that can be used to make scientific inferences.

Thus, the survey method was flawed since the sample was not random.
