The graph of f(x)=sin(x) is transformed into a new function, g(x) , by stretching it vertically by a factor of 4 and shifting it 3 units to the right. What is the equation of the new function g(x) ?
Answer:
g(x) = 4 sin(x - 3)
Step-by-step explanation:
* Lets revise some transformation
- If the function f(x) translated horizontally to the right by h units, then
the new function g(x) = f(x - h)
- If the function f(x) translated horizontally to the left by h units, then
the new function g(x) = f(x + h)
- If the function f(x) translated vertically up by k units, then the new
function g(x) = f(x) + k
- If the function f(x) translated vertically down by k units, then the
new function g(x) = f(x) – k
- A vertical stretching is the stretching of the graph away from the
x-axis
- If k > 1, the graph of y = k • f(x) is the graph of f(x) vertically
stretched by multiplying each of its y-coordinates by k.
- A vertical compression is the squeezing of the graph toward
the x-axis.
- If 0 < k < 1 (a fraction), the graph of y = k • f(x) is the graph of f(x)
vertically compressed by multiplying each of its y-coordinates by k.
* Lets solve the problem
∵ f(x) = sin(x)
∵ f(x) is stretching vertically by a factor of 4
∴ f(x) multiplied by 4
∵ f(x) is shifting 3 units to the right
∴ We will change x to (x - 3)
∵ The new function is g(x)
∴ g(x) = 4 sin(x - 3)
- The attached graph for more understand
f(x) is the red graph
g(x) is the blue graph
Answer:
g(x) = 4 sin(x - 3)
Step-by-step explanation:
The given function is:
f(x) = sin(x)
Stretching by a factor of 4:
A vertical stretch or compression of f(x) can be expressed as:
cf(x), where c is any constant
if c > 1, it indicates a stretch in vertical direction and if 0 < c < 1, it indicates a compression by a factor of c in vertical direction.
Since, given function is being stretched by a factor of 4, the transformed function will become:
4f(x)
Shifting by 3 units right:
A shift of f(x) to right can be obtained by subtracting c from every occurrence of x in f(x) , where c is the number of units f(x) is being shifted in right direction. Since in this case f(x) is shifted 3 units to right, the transformed function will be:
f(x - 3)
Applying both the transformations to f(x), we get g(x) as:
g(x) = 4 f(x - 3)
g(x) = 4 sin(x - 3)

Find the perimeter of the regular parallelogram.
Answer:
Approx. 48 cm
Step-by-step explanation:
The two horizontal sides of this parallelogram have length 12 cm each.
The length of one slanting side can be estimated by (eye: the base of the triangle partially outlined with a dashed line is approx. 3 cm. Then, using the Pyth. Thm., we estimate the hypotenuse of this triangle to be
sqrt(3^2 + 10^2), or sqrt(109), which is approx. 10.45.
Thus, the estimated perimeter is
P = 2L + 2W, which, here, is
P = 2(12 cm) + 2(10.45 cm), or 44.9 cm.
The fourth answer, 48 cm, is the one closest to this estimated 44.9 cm.

y = 1 (answer).
Given the parametric equations, x = 2t + 5 and y = 3t^2 - 1, find the point on the graph at time, t = 4.
Please explain how you got your answer.
Answer: (13, 47)
The expression t = 4 means that 4 units of time have come off the clock (possibly 4 seconds). Plug this value into each equation given for x and y
x = 2*t + 5 = 2*4 + 5 = 8 + 5 = 13
y = 3*t^2 - 1 = 3*4^2 - 1 = 3*16 - 1 = 48 - 1 = 47
In short, if t = 4 then it leads to x = 13 and y = 47 at the same time. These x and y values pair up to get the final answer (13,47)
--------------
Here's an update:
If t = 2, then,
x = 2t+5 = 2*2+5 = 4+5 = 9y = 3t^2-1 = 3*2^2-1 = 3*4-1 = 12-1 = 11In short, if t = 2, then x = 9 and y = 11
The point on the graph at time [tex]\(t = 4\) is \((13, 47)\)[/tex].
To find the point on the graph at time [tex]\(t = 4\)[/tex] given the parametric equations [tex]\(x = 2t + 5\)[/tex] and [tex]\(y = 3t^2 - 1\)[/tex], substitute [tex]\(t = 4\)[/tex] into both equations.
1. For [tex]\(x\)[/tex]:
[tex]x = 2t + 5[/tex]
[tex]x = 2(4) + 5[/tex]
[tex]x = 8 + 5[/tex]
[tex]x = 13[/tex]
So, at [tex]\(t = 4\), \(x = 13\)[/tex].
2. For [tex]\(y\)[/tex]:
[tex]y = 3t^2 - 1[/tex]
[tex]y = 3(4)^2 - 1[/tex]
[tex]y = 3(16) - 1[/tex]
[tex]y = 48 - 1[/tex]
[tex]y = 47[/tex]
So, at [tex]\(t = 4\), \(y = 47\)[/tex].
Therefore, the point on the graph at time [tex]\(t = 4\) is \((13, 47)\)[/tex].

Sorry if this isnt helpful: Im just going off stuff i learned to see if this will help you at all. Im only in 7th so.. Sorry in advance!!
Step-by-step explanation:
To find the rate, you need to create a unit rate table thing, like this:
5/3 = ?/1 To do this, you would need to divide 5 by 3 and 3 by 3 to get y and x. You get: 1.666 continued. Rounded, about 1.7 . so your unit rate for part A is 1.7/1. You would do the same thing. 2/3 = ?/1. I will let you solve that :)))
Finished A! Now B:
To compare, we use the butterfly method! so 1.7/1 o ?1. cross multiply, and whichever number is bigger comes on top. Then you would explain why that number is bigger. BAM

Phyllis Doran worked at Symmes Medical Center for 7 1/2 hours on Monday and from 8:00 a.M. Until 1:00 p.M. On Tuesday What is the total number of hours she worked
Answer:
[tex]12\frac{1}{2}[/tex] hours.
Step-by-step explanation:
We have been given that Phyllis Doran worked at Symmes Medical Center for 7 1/2 hours on Monday and from 8:00 a.M. Until 1:00 p.M.
Let us find the number of hours between 8:00 am to 1:00 pm.
There are 4 hours between 8:00 am to 12 noon and 1 hour from noon to 1:00 pm. So the total number of hours between 8:00 am to 1:00 pm is 5 hours.
Now let us find total number of hours worked by Phyllis Doran by adding 7 1/2 and 5.
[tex]\text{The total number of hours Doran worked}=7\frac{1}{2}+5[/tex]
[tex]\text{The total number of hours Doran worked}=12\frac{1}{2}[/tex]
Therefore, the total number of hours worked by Phyllis Doran is [tex]12\frac{1}{2}[/tex] hours.

5. The ordered pair (h, k) is typically used to name the point to which a function is translated. The vertex of the function f(x) = |x| is (0, 0). When it is translated to (h, k), the function becomes ...
... q(x) = |x -h| +k
If the new vertex is (3, 0), then h = 3 and k = 0. This is consistent with the equation shown. (k = 0 means q(x) = |x -h|.)
If a → b is true, then ~a → b is also true.
Answer:
False
Step-by-step explanation:
To determine whether the statemaent "If [tex]a\Rightarrow b[/tex] is true, then [tex]\neg a\Rightarrow b[/tex] is also true" holds, you can form the truth table:
[tex]\begin{array}{ccccc}a&b&a\Rightarrow b&\neg a&\neg a\Rightarrow b\\1&1&1&0&1\\1&0&0&0&1\\0&1&1&1&1\\0&0&1&1&0\end{array}[/tex]
When the result of the column [tex]a\Rightarrow b[/tex] takes value 1 (true), the result of the column [tex]\neg a\Rightarrow b[/tex] is not always 1, then the statement is false.

Given two events A and B of a sample set where P[A] = .20 P[not B] = .40 P[B|A] = .25 What is P[A or B]?
Answer:
Given two events A and B of a sample set :-
P[A] = 0.20
P[not B]=0.40
[tex]P[B/A]=0.25[/tex]
To find P[A or B]:
[tex]P[A or B] = P[A] + P[B] - P[A \cap B][/tex] ......[1]
Calculate for [tex]P[B][/tex] and [tex]P[A \cap B][/tex]
P[B] = 1- P[not B]
Substitute the value P[not B] we get;
P[B] = 1-0.40 = 0.60
[tex]P[A \cap B] = P[B/A] \cdot P[A][/tex]
Substitute the given values we get;
[tex]P[A \cap B] = 0.25 \cdot 0.20 = 0.05[/tex]
Then;

A company buys paper clips at the rate of $7.50 per box for the first 10 boxes, $5.50 per box for the next 10 boxes, and $3.50 per box for any additional boxes. How many boxes of paper clips can be bought for $221.00?
Answer:
46 boxes
Step-by-step explanation:
First 10 boxes can be bought for [tex]7.5*10=75[/tex]Next 10 boxes can be bought for [tex]5.5*10=55[/tex]So for a total of 20 boxes, the cost is [tex]75+55=130[/tex]
We have remaining [tex]221-130=91[/tex]
Each additional box costs 3.5, so for 91 dollars, we can get:
[tex]\frac{91}{3.5}=26[/tex] boxes
So, total [tex]10+10+26=46[/tex] boxes can be bought for $221.00
Given the budget of $221 and the stipulated price rates, the company can buy a total of 46 boxes of paper clips.
Explanation:To solve this problem, we first need to calculate how many boxes the company can buy with $221 considering the different rates. The first 10 boxes cost $7.50 each, so ten boxes would cost $75. The next 10 boxes cost $5.50 each, so these together would cost $55. This means that 20 boxes cost $130. Subtract this amount from the total budget, which leaves $91.
Since each additional box over 20 boxes costs $3.50, we divide our remaining fund, $91, by $3.50 to determine how many more boxes can be purchased. This comes out to roughly 26 boxes.
So, adding up all the boxes, the company can buy 10 boxes (at $7.50) + 10 boxes (at $5.50) + 26 boxes (at $3.50) = 46 boxes with $221.
