Which transformations are needed to change the parent cosine function to y = 0.35 cosine (8 (x minus startfraction pi over 4 endfraction))?
Answers
The transformations that are needed to change the parent cosine function to y = 0.35×cos(8(x-π/4)) are:
vertical stretch of 0.35horizontal compression of period of [tex]\dfrac{\pi}{4}[/tex]phase shift of [tex]\dfrac{\pi}{4}[/tex] to right How does transformation of a function happens?The transformation of a function may involve any change.
Usually, these can be shift horizontally (by transforming inputs) or vertically (by transforming output), stretching (multiplying outputs or inputs) etc.
If the original function is [tex]y=f(x)[/tex]A, assuming horizontal axis is input axis and vertical is for outputs, then:
Horizontal shift (also called phase shift):[tex]y=f(x+c)[/tex]Left shift by c units: earlier)Right shift by c units: [tex]y=f(x-c)[/tex] output, but c units late)Vertical shift:Up by d units: [tex]y=f(x)+d[/tex]Down by d units: [tex]y=f(x)-d[/tex]Stretching:Vertical stretch by a factor k: [tex]y=k\times f(x)[/tex]Horizontal stretch by a factor k: [tex]y=f(\dfrac{x}{k})}[/tex]For this case, we're specified that:
y = cos(x) (the parent cosine function) was transformed to
[tex]y=0.35cos(8(x-\pi/4)[/tex]
We can see its vertical stretch by 0.35, right shift by horizontal stretch by 1/8
Period of cos(x) is of length. But 1.8 stretching makes its period shrink to
[tex]\dfrac{2\pi}{8}=\dfrac{\pi}{4}[/tex]
Thus, the transformations that are needed to change the parent cosine function to y = 0.35×cos(8(x-π/4)) are:
vertical stretch of 0.35
horizontal compression to period of (which means period of cosine is shrunk to which originally was )
phase shift of to right

Por cinco boletos para un concierto de rock y tres boletos para un partido de fútbol se pagaron $720 y por dos boletos para el mismo concierto y seis para el mismo partido de fútbol se pagaron $480 ¿Cuál es el valor del boleto para cada uno de los eventos?
Answers
The value of tickets for rock concert is $120 and the value of tickets for soccer match is $40.
How to calculate the value?From the information, for five tickets for a rock concert and three tickets for a soccer match, they paid $720 and for two tickets for the same concert and six for the same soccer game, they paid $480.
Let the value of tickets for rock concert = x
Let the value of tickets for soccer match = y
Based on the information given, the equation will be:
5x + 3y = 720 .... i
2x + 6y = 480 ..... ii
Multiply equation i by 2
Multiply equation ii by 5
10x + 6y = 1440
10x + 30y = 2400
Subtract
24y = 960
y = 960 / 24
y = 40
Therefore, x will be:
5x + 3y = 720
5x + 3(40) = 720
5x + 120 = 720
5x = 720 - 120
5x = 600
Divide
x = 600 / 5
x = 120

Find the area in square meters of a circular pond with a radius of 8 ft. Use 3.14 for π, and round your answer to the nearest hundredth.
(1 m ≈ 3.2808 ft)
Answers
The area of a circular pond with a radius of 8 ft is, 18.67 m².
What is Circle?The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
We have to given that;
The radius of circle = 8 feet
Now, We know that;
⇒ 1 feet = 0.3048 m
⇒ 8 feet = 8 × 0.3048 m
= 2.4384 m
We know that;
⇒ Area of circle = πr²
Substitute all the values, we get;
⇒ Area of circle = 3.14 × (2.4384)²
⇒ Area of circle = 3.14 × 5.94
⇒ Area of circle = 18.67 m²

3(8. 50 +1. 25 +1. 50) +5. 25 = 38. 90
1. 0525{3(8. 50 +1. 25 +1. 50)} = 35. 52
1. 0525{3(8. 50 +1. 25) +2(1. 50)} = 33. 94

What is Population Density?The population density of an area is the Number of Entities in that space/Total Area occupied by the population.
A scientist has four Petri dishes of different sizes. each dish contains a different number of bacteria.
It can also be written as Dp = N/A.
Because the Dp of Dish C and Dish D is approximately 0.68, we can say that they have approximately the same Dp.

20 different prizes are distributed to a group of 180 people. Since the prizes are different, it matters who gets which prize. How many ways are there to distribute the prizes if each person can receive at most one prize
Answers
We will see that the total number of ways in which we can distribute 20 different prizes among 180 people is:
C = 6.818e46
In how many ways the prizes can be distributed?
Here we need to count how many selections do we have. Each prize will be a selection, so we have 20 selections.
Now we need to count the numbers of 6for each selection.
For the first prize, there are 180 options.
For the second prize, there are 179 options (because one person already got a prize).
For the third prize, there are 178 options.
And so on.
The total number of combinations is given by the product between the numbers of options:
C = 180*179*178*...*161*160 = 6.818e46

Answers
Answer:
a = 5
Step-by-step explanation:
let's label the triangle as a, b and c
where b is the hypotenuse and c is the adjacent of the hypotenuse a to be the height.
from the formula
a² + c² = b²
we substitute the values to find a
so,
a² + 12² = 13²
but we don't know "a" so we make it stand alone by grouping liked terms.
a² = 13² - 12²
a² = 25
we need "a" not "a²" so we take the square root of both sides to get rid of "a²" leaving "a"
[tex] \sqrt{ {a}^{2} } = \sqrt{25} [/tex]
and the answer will be
a = 5

Answers
Answer:
50 inches
Step-by-step explanation:
Given: S and E are the midpoints of BA and AM. and EM = 9
Therefore, then the length of AB = 18 and AM = 18
Use the similar triangle properties.
7/BM = 9/18
BM = (7*18)/9
BM = 7*2 = 14 inches.
Therefore, the perimeter of BAM is = AB + BM + AM

A sound wave travels through iron at a rate of 3120 / s . At what rate does the sound wave travel in / h?
Answers

Step-by-step explanation:
You have 3120m/s and want kilometers per hour. There are 1000m in 1km, and 3600sec in 1h:
[tex] \frac{3120}{1} \frac{m}{s} \times \frac{1}{1000} \frac{km}{m} \times \frac{3600}{1} \frac{s}{h} [/tex]
Meters cancel. Seconds cancel. This leaves kilometers per hour:
