What effect does changing the function f(x)=3sin(x)+1to the function g(x)=3sin(x/4)+2 have on the graph of f(x)?
The graph is compressed vertically by a factor of 4 and shifted right 1 unit.
The graph is stretched horizontally by a factor of 4 and shifted up 1 unit.
The graph is stretched vertically by a factor of 4 and shifted down 1 unit.
The graph is compressed horizontally by a factor of 4 and shifted left 1 unit.
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

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

Which is the inverse of the function f(x) = 4x − 9?
Step-by-step explanation:
x and y trade places.
f(x) = y = 4x - 9
y + 9 = 4x
x = (y + 9)/4
and to make it a true function notation, we need to rename x to y and vice versa and get
y = (x + 9)/4

12x^2/28x
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)
A theme park has a ride that is located in a sphere. The ride goes around the widest circle of the
sphere which has a circumference of 489.84 yd. What is the surface area of the sphere? Use 3.14
for
The surface area of the sphere is about yd?.
(Type an integer or decimal rounded to the nearest hundredth as needed.)
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: 67So 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%.

A line passes through ( – 8,6) and ( – 2, 3).
Find the y-intercept, b, of the line.
Answer:
[tex]\displaystyle [0, 2][/tex]
Step-by-step explanation:
First, find the rate of change [slopes]:
[tex]\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m \\ \\ \frac{-6 + 3}{8 - 2} = m; \frac{-3}{6} \\ \\ -\frac{1}{2} = m[/tex]
We now plug the above information into the Slope-Intercept Formula. It does not matter which ordered pair is selected:
[tex]\displaystyle y = mx + b \\ \\ 3 = -\frac{1}{2}[-2] + b \hookrightarrow 3 = 1 + b; \boxed{2 = b} \\ \\ y = -\frac{1}{2}x + 2[/tex]
OR
[tex]\displaystyle y = mx + b \\ \\ 6 = -\frac{1}{2}[-8] + b \hookrightarrow 6 = 4 + b; \boxed{2 = b} \\ \\ y = -\frac{1}{2}x + 2[/tex]
Therefore, the line passes through the y-intercept of [tex]\displaystyle [0, 2].[/tex]

The graph g(x) is the graph of f(x) translated
✓ units
✓, and g(x) =
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.
A rectangle has an area of 31.2 square millimeters and a heigt of 5.2 millimeters. What is the length of the base
Answer:
6 millimeters
Step-by-step explanation:
The formula for a rectangle is length * height = area.
Since we know the area and height, we can plug it in to the formula:
length * 5.2 = 31.2
So the length is just dividing 5.2 in 31.2 which gives 6 millimeters.

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

Move all terms to the left side and set equal to zero. Then set each factor equal to zero.
Answer:
Step-by-step explanation:
Sum = coefficient of x = -5
Product = constant * coefficient of x² = 1 * 6 = 6
Factors = (-2) , (-3)
When we multiply, (-2)*(-3) we get = +6 and we add (-2) + (-3) = -5
Using this factors rewrite the middle terms
x² - 5x + 6 = 0
x² - 3x - 2x + (-2)*(-3) = 0
x(x - 3) - 2(x - 3) = 0
(x - 3)(x-2)=0
x - 3 = 0 ; x -2 =0
x = 3 ; x = 2
Solution: x = 2 , 3
