Answers

Answer:

The graph is stretched horizontally by a factor of 4 and shifted up 1 unit

Step-by-step explanation:

The effect of transforming the function is (b) The graph is stretched horizontally by a factor of 4 and shifted up 1 unit

How to interpret the transformations of the functions?

The functions are given as:

f(x) = 3sin(x)+1

g(x) = 3sin(x/4)+2

Start by stretching the function f(x) horizontally by a scale factor of 4.

So, we have:

f'(x) = 3sin(x/4) + 1

Next, shift the function f'(x) upward by 1 unit.

So, we have:

f'(x) = 3sin(x/4) + 1 + 1

Evaluate the sum

f'(x) = 3sin(x/4) + 2

Rewrite as:

g(x) = 3sin(x/4) + 2

Hence, the effect of transforming the function is (b) The graph is stretched horizontally by a factor of 4 and shifted up 1 unit

On Tuesday, Karen finished all her chores in 3/4 of an hour. On Wednesday, she finished her chores in 5/12 of an hour. How much faster was Karen on Wednesday than Tuesday?

Answers

1 hour = 60 minutes

Tuesday: 60 divided by 4 = 15. Karen did it 3/4 of a hour so we multiply 15 by 4 which is 45. 45 equals 45 minutes. On Tuesday, Karen finished her chores in 45 minutes

Wednesday: first we divide 60 by 12 which is 5. 5 would equal 5 minutes. now we multiply 5 by 5 which is 25. Karen finished her chores in 25 minutes.

Answer: Karen finished her chores 20 minutes faster on Wednesday than Tuesday.

The scores on a psychology exam were normally distributed with a mean of 52 and a standard deviation of 6. About what percentage of scores were less than 40​?

Answers

Using the normal distribituion, it is found that 2.28% of of scores were less than 40.

Normal Probability Distribution

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.

In this problem, the mean and the standard deviation are given by, respectively:

[tex]\mu = 52, \sigma = 6[/tex].

The proportion of scores that were less than 40​ is the p-value of Z when X = 40, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{40 - 52}{6}[/tex]

[tex]Z = -2[/tex]

[tex]Z = -2[/tex] has a p-value of 0.0228.

2.28% of of scores were less than 40.

12x^2/28x

Answers

Answer: (-6x - 5) • (2x + 3)

Step-by-step explanation:

((0 -  (22•3x2)) -  28x) -  15

Pull out like factors :

-12x2 - 28x - 15  =   -1 • (12x2 + 28x + 15)

Trying to factor by splitting the middle term

3.2     Factoring  12x2 + 28x + 15

The first term is,  12x2  its coefficient is  12 .

The middle term is,  +28x  its coefficient is  28 .

The last term, "the constant", is  +15

Step-1 : Multiply the coefficient of the first term by the constant   12 • 15 = 180

Step-2 : Find two factors of  180  whose sum equals the coefficient of the middle term, which is   28 .

     -180    +    -1    =    -181

     -90    +    -2    =    -92

     -60    +    -3    =    -63

     -45    +    -4    =    -49

     -36    +    -5    =    -41

     -30    +    -6    =    -36

     -20    +    -9    =    -29

     -18    +    -10    =    -28

     -15    +    -12    =    -27

     -12    +    -15    =    -27

     -10    +    -18    =    -28

     -9    +    -20    =    -29

     -6    +    -30    =    -36

     -5    +    -36    =    -41

     -4    +    -45    =    -49

     -3    +    -60    =    -63

     -2    +    -90    =    -92

     -1    +    -180    =    -181

     1    +    180    =    181

     2    +    90    =    92

     3    +    60    =    63

     4    +    45    =    49

     5    +    36    =    41

     6    +    30    =    36

     9    +    20    =    29

     10    +    18    =    28    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  10  and  18

                    12x2 + 10x + 18x + 15

Step-4 : Add up the first 2 terms, pulling out like factors :

                   2x • (6x+5)

             Add up the last 2 terms, pulling out common factors :

                   3 • (6x+5)

Step-5 : Add up the four terms of step 4 :

                   (2x+3)  •  (6x+5)

            Which is the desired factorization

Answer: (-6x - 5) • (2x + 3)

for
The surface area of the sphere is about yd?.
(Type an integer or decimal rounded to the nearest hundredth as needed.)

Answers

Answer:

76,400

Step-by-step explanation:

I think this is right, not sure though.

Surface area of sphere:

[tex]4\pi \times r {}^{2} [/tex]

Circumference :

[tex]2(\pi \times r)[/tex]

489.84 = 2 × 3.14 × r

2 × 3.14 = 6.28

489.84 = 6.28 × r

radius = 489.84 ÷ 6.28

R =78

Surface Area = 4 × 3.14 × (78)^2

Surface area = 76,415.04

= 76,400

By analyzing the data tables given, we will see that:

1) The range is 28.

2) The graph can be seen at the end.

3) There are clusters at 16 and 17, and 25 is an outlier.

4) The range decreases almost by 50%.

How to get the range for the data?

The range is defined by the difference between the largest and smallest values from the data set.

In this case, the largest is: 95The smallest is: 67

So the range is: R = 95 - 67 = 28

The correct option is D.

How to make a line plot?

For each time that a number appears, you need to make a dot above the correspondent value.

The graph can be seen below.

3) we have clusters on 16 and 17, and as you can see, the value 25 is really away of the rest of the values, so we have a gap, and 25 is an outlier.

4) With the 25, the range is:

25 - 16 = 9

If we remove it, the range is:

21 - 16 = 5

So the range decreases almost by a 50%.

The graph g(x) is the graph of f(x) translated
✓ units
✓, and g(x) =

Answers

Step-by-step explanation:

f(x) goes through the point (0, 1).

g(x) goes through (2, 1) for the same y value.

that means g(x) is f(x) translated 2 units to the right.

but we could also look at the same x value (0).

then g(x) goes through (0, -5).

and that means g(x) is f(x) translated 6 units down.

since it is a line function, shifting it left/right or up/down makes no difference to the shape or position of the new curve itself.

as it looks like you don't have 6 in the drop-down menu, then 2 units (to the right) is the desired correct result.

that means g(x) = f(x-2) = 3(x-2) + 1 = 3x - 6 + 1 = 3x - 5

and that is what the graph is showing us.

Does 3(7x +7) + 5x represent a number that is greater than, less than, or equal to 5(5x + 10)

Answers

Answer:

Step-by-step explanation:

from

3(7x +7) + 5x = 5(5x + 10)

21x+21+5x     = 25x + 50

26x + 21        = 25x + 50

26x-25x +21 = 50

1x+21            = 50

1x                 =50-21

            x      = 29

equal when x= 29

try to x> 29      such as 30  

3(7(30) +7) + 5(30)     ?    5(5(30) + 10)

1470    ?      800

so  greater than when x >29

finally  

less than when x<29

Answer:

When x = 29:   the expressions are equal

When x < 29:   3(7x + 7) + 5x is less than 5(5x + 10)

When x > 29:    3(7x + 7) + 5x is greater than 5(5x + 10)

Step-by-step explanation:

Given expressions:

3(7x + 7) + 5x5(5x + 10)

Expand both expressions:

   3(7x + 7) + 5x

⇒ 21x + 21 + 5x

⇒ 26x + 21

   5(5x + 10)

⇒ 25x + 50

Equate the expanded expressions and solve for x

   26x + 21 = 25x + 50

⇒ 26x - 25x = 50 - 21

⇒ x = 29

Therefore, the expressions are equal when x = 29

When x < 29:    3(7x + 7) + 5x < 5(5x + 10)

When x > 29:    3(7x + 7) + 5x > 5(5x + 10)

Using this factors rewrite the middle terms

x² - 5x + 6 = 0

x² - 3x - 2x + (-2)*(-3) = 0

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