The point (1,6) is on the graph of y=f(x). What would the new co-ordinates be for the function g(x)=2f(1/3(x-1)) +5?
Answers
The new coordinates for the function g(x) at the point (1,6) are (1,5).
What is coordinates ?
Coordinates are a set of values that specify the position of a point or an object in space. They are used to locate points in a plane or in three-dimensional space. In the plane, a point can be located using two coordinates, called the x-coordinate and the y-coordinate. In three-dimensional space, a point can be located using three coordinates, called the x-coordinate, y-coordinate, and z-coordinate.
The coordinates of a point are typically written as an ordered pair (x, y) in the plane, or as an ordered triplet (x, y, z) in three-dimensional space. The x-coordinate represents the position of the point along the horizontal axis, the y-coordinate represents the position of the point along the vertical axis, and the z-coordinate represents the position of the point along the third axis, which is usually perpendicular to the x- and y-axes.
To find the new coordinates for the function g(x) given that the point (1,6) is on the graph of y = f(x), we can substitute x = 1 and y = 6 into the equation for g(x) and simplify:
g(x) = 2f(1/3(x-1)) + 5
g(1) = 2f(1/3(1-1)) + 5
g(1) = 2f(0) + 5
g(1) = 2f(0) + 5(1)
g(1) = 2f(0) + 5
Since the point (1,6) is on the graph of y = f(x), we know that f(1) = 6. To find f(0), we can use the fact that the function passes through the origin (0,0) because:
g(1) = 2f(0) + 5
g(0) = 2f(-1/3) + 5
Since the point (1,6) is on the graph of y = f(x), we can use it to find the value of f(1/3) as follows:
(1,6) is on the graph of y = f(x)
so f(1) = 6
and 1/3(1-1) = 0
This means that the point (1/3, f(1/3)) is on the graph of y = f(x). Therefore, we can use the transformation in g(x) to find the new y-coordinate for g(1) as follows:
g(1) = 2f(1/3(1-1)) + 5
g(1) = 2f(0) + 5
g(1) = 2(0) + 5
g(1) = 5
Therefore, the new coordinates for the function g(x) at the point (1,6) are (1,5).

By multiplication, 500 times 500 is 250,000 using distributive property.
What is Multiplication?Multiplication is an arithmetic operation that combines two or more quantities into a single quantity. The result of multiplication is called the product. Multiplication is usually represented by the symbol "×" or "*".
For example, the product of 3 and 4 is 12, which is written as 3 × 4 = 12 or 3 * 4 = 12. In general, to multiply two numbers a and b, we write a × b or a * b, and the result is the product of the two numbers.
Multiplication is also distributive over addition, which means that a × (b + c) = (a × b) + (a × c) for any values of a, b, and c.
We are given :

A component with time to failure T has failure rate z(t)= 2. 0*10-6 t/hour for t>0 1) Determine the probability that the component survives 200 hours 2) Determine the probability that a component, which is functioning after 200 hours, is still functioning after 400 hours
Answers
The probability that the component survives 200 hours is approximately 0.9802. The probability that a component, which is functioning after 200 hours, is still functioning after 400 hours, is approximately 0.8703.
What is probability?
Probability is a numerical representation of the likelihood or chance of a specific event occurring. It is typically expressed as a value between 0 and 1, with 0 indicating that the event is impossible and 1 indicating that the event is certain to occur.
To determine the probability that the component survives 200 hours, we need to calculate the survival function, which is the probability that the component lasts longer than 200 hours. We can use the formula:
[tex]$$ S(t) = e^{-\int_0^t z(u) du} $$[/tex]
where [tex]$S(t)$[/tex] is the survival function and [tex]$\int_0^t z(u) du$[/tex] is the integral of the failure rate from 0 to [tex]$t$[/tex].
In this case, the failure rate is [tex]$z(t) = 2.0\times10^{-6}t/\text{hour}$[/tex] for [tex]$t > 0$[/tex]. Integrating this from 0 to 200 gives:
[tex]$$ \int_0^{200} z(t) dt = \int_0^{200} (2.0\times10^{-6}t) dt =[/tex] [tex]\left[\frac{(2.0\times10^{-6})}{2}t^2\right]_0^{200} = 0.02 $$[/tex]
Substituting this into the survival function formula gives:
[tex]$$ S(200) = e^{-\int_0^{200} z(t) dt} = e^{-0.02} \approx 0.9802 $$[/tex]
Therefore, the probability that the component survives 200 hours is approximately 0.9802.
To determine the probability that a component, which is functioning after 200 hours, is still functioning after 400 hours, we need to use the conditional probability formula:
[tex]$ P(T > 400|T > 200) = \frac{P(T > 400 \cap T > 200)}{P(T > 200)} $$[/tex]
We can calculate the numerator using the survival function:
[tex]$ P(T > 400 \cap T > 200) = S(400) $$[/tex]
To find [tex]$S(400)$[/tex], we need to integrate the failure rate from 0 to 400:
[tex]$$ \int_0^{400} z(t) dt = \int_0^{400} (2.0\times10^{-6}t) dt = \left[\frac{(2.0\times10^{-6})}{2}t^2\right]_0^{400} = 0.16 $$[/tex]
Substituting this into the survival function formula gives:
[tex]$$ S(400) = e^{-\int_0^{400} z(t) dt} = e^{-0.16} \approx 0.8534 $$[/tex]
To find the denominator, we can use the survival function we found earlier:
[tex]$ P(T > 200) = S(200) = e^{-0.02} \approx 0.9802 $$[/tex]
Substituting these values into the conditional probability formula gives:
[tex]$ P(T > 400|T > 200) = \frac{S(400)}{S(200)} \approx \frac{0.8534}{0.9802} \approx 0.8703 $$[/tex]
Therefore, the probability that a component, which is functioning after 200 hours, is still functioning after 400 hours, is approximately 0.8703.
1) The probability that the component survives 200 hours is approximately 0.9802.
2) The probability that a component, which is functioning after 200 hours, is still functioning after 400 hours, is approximately 0.8703.

A hotel has 320 rooms. Some are singles, and some are doubles. The single room cost 40$ and the double rooms cost 65$. Because of and event in town all of the hotel rooms are occupied. The sales tonight are 15,600$. How many of each type of room does the hotel have?
Answers
As a result, the hotel has 208 single rooms and 112 double rooms. We can now use these two equations to find the values of x and y.
what is equation ?An equation in mathematics is a claim that two mathematical expressions are equivalent. In an equation, the two expressions on either side are separated by the equals sign (=). As in the following equation: 3x + 2 = 11 declares that the formula 11 is identical to the formula 3x + 2. Finding the value of x that causes the equation to be true is the first step towards solving this equation. By first removing 2 from both sides of the equation and then dividing by 3, we may find x in this situation: 3x + 2 - 2 = 11 - 2 (subtracting 2 from both sides) (subtracting 2 from both sides) .3x = 9 (simplifying the right side) (simplifying the right side) .
given
Assume that there are x single rooms and y double rooms at the hotel.
We may create an equation since we are aware that there are 320 rooms in the hotel overall:
x + y = 320 (Equation 1) (Equation 1)
We can create another equation based on sales since we also know the prices for each type of accommodation and the overall sales:
40x + 65y = 15,600 (Equation 2) (Equation 2)
We can now solve for x and y using these two equations. To accomplish this, one method is to solve for x in Equation 1 and replace it in Equation 2:
x + y = 320
x = 320 - y
Equation 2 using x = 320 - y as a replacement:
12,800 - 40y + 65y = 15,600
25y = 2,800 y = 112
40x + 65y = 15,600
40(320 - y) + 65y
= 15,600
There are 112 double rooms in the hotel. In order to determine the number of single rooms, we can reenter this value into Equation 1 as follows:
x + y = 320
x + 112 = 320
x = 208
As a result, the hotel has 208 single rooms and 112 double rooms. We can now use these two equations to find the values of x and y.

Therefore, the length of the perpendicular side x is approximately 12.64 feet, rounded to two decimal places.
What is trigonometric ratio?A trigonometric ratio is a mathematical function that relates the sides of a right triangle to its angles. There are three basic trigonometric ratios: sine, cosine, and tangent. Each of these ratios is defined as the ratio of two sides of the triangle. Sine (abbreviated as sin) is the ratio of the length of the side opposite an acute angle to the length of the hypotenuse. That is, sin(theta) = opposite/hypotenuse. Cosine (abbreviated as cos) is the ratio of the length of the adjacent side to the length of the hypotenuse. That is, cos(theta) = adjacent/hypotenuse. Tangent (abbreviated as tan) is the ratio of the length of the opposite side to the length of the adjacent side. That is, tan(theta) = opposite/adjacent.
Here,
We can use the trigonometric ratio of sine to solve for x in this problem.
Sine is defined as the ratio of the length of the opposite side (in this case, x) to the length of the hypotenuse (21 feet):
sin(37°) = x/21
We can solve for x by multiplying both sides of the equation by 21:
x = 21 sin(37°)
Using a calculator to evaluate sin(37°), we get:
sin(37°) ≈ 0.6018
Substituting this value into the equation, we get:
x ≈ 21(0.6018)
x ≈ 12.64

Graph the function by hand using the techniques you were taught in this unit: f(x) = 2sin(x)-2. Your work and explanations must use the methods taught in this class.
• Amplitude: 2
• Period: 2pi
• Midline: y = -2
• y-intercept: (0, -2)
Answers
To graph the function f(x) = 2sin(x)-2, we can start by plotting the y-intercept (0, -2).
Next, we can use the amplitude of 2 to mark the highest and lowest points of the graph. The highest point will be 2 units above the midline at y = 0, and the lowest point will be 2 units below the midline at y = -4.
To establish the period of the function, we need to identify the distance between one complete cycle of the graph. Since sine has a period of 2pi, we can see that the period of our function is also 2pi.
Starting from the y-intercept, we can mark a point on the graph that is one-quarter of the way through a cycle, at x = pi/2. The sine function will be at its maximum value of 1 at this point, so the graph will be at y = 0 + 2

Hector has a collection of nickels, dimes, and quarters totaling 122 coins. The number of dimes he has is 3 more than four times the number of nickels, and the number of quarters he has is 19 less than the number of dimes. How many coins of each kind does he have?
Answers
Answer: 15 nickels, 63 dimes, 44 quarters
Step-by-step explanation:
x=number of nickels
4x+3=number of dimes
4x+3-19=number of quarters
Solve the following equation:
x+4x+3+4x+3-19=122
9x-13=122
x=15
Plug x back into the expressions:
Number of nickels=15
Number of dimes:

Answers
Both of the two triangles are similar by SSS similarity postulate.
How to Identify Similar Triangles?Similar triangles are defined as triangles that have the same shape, but their sizes may vary. This means that, if two triangles are similar, then we can say that their corresponding angles are congruent and corresponding sides are in equal proportion.
Looking at the 2 given triangles, we can see the ratio if corresponding sides as:
39/13 = 3
39/13 = 3

What type of function is a circle?
Answers
is a pineapple
Step-by-step explanation:this is becuase you should work it out youself you silly goose
Answer:
circle is not a function.
Step-by-step explanation:
there are certain rules to define a mapping as function, one of them is function should not have more than 1 value at a given x.
for illustration purpose consider the below diagram,
as you can see in the given circle at x = 2, there are two different values of y, therefore equation of circle doesn't qualify as a function. half circle can be defined as a function (by restricting the range to only positive or negative values).

1. Find the zeroes of the following quadratic polynomials and verify the relationship between
the zeroes and the coefficients.
(i) x²-2x-8
Answers
Answer:
The zeroes are -2 and 4.
Step-by-step explanation:
x^2 - 2x - 8 = 0
(x + 2)(x - 4) = 0
x + 2 = 0 or x - 4 = 0
x = -2, 4
The general form of the equation is ax^2 + bx + c = 0.
The sum of the zeroes should be equal to -b/a:-
-2 + 4 = 2
and -(-2)/1 = 2
Verified
The product of the zeroes should be c/a = -8:-
-2 * 4 = -8.

also bought some corn kernels. Sunflower seeds and corn
kernels each cost $2.20 per pound. The total amount
Manuel spent on the sunflower seeds and corn kernels was
$9.35.
Enter the number of pounds of corn kernels Manuel
purchased.
Answers
Manuel purchased 1.75 pounds of corn kernels.
What is equation?An equation is a mathematical statement that shows the equality between two expressions. The expressions on either side of the equals sign are called the left-hand side and the right-hand side of the equation. An equation can be written in many different forms, but the most common form is: Left-hand side = Right-hand side
In the given question,
Let's use x to represent the number of pounds of corn kernels Manuel purchased.
We know that Manuel bought 2.5 pounds of sunflower seeds, and that both the sunflower seeds and corn kernels cost $2.20 per pound.
The total amount Manuel spent on the sunflower seeds and corn kernels was $9.35, so we can write the equation: 2.2(2.5) + 2.2x = 9.35
Simplifying the left side of the equation, we get: 5.5 + 2.2x = 9.35
Subtracting 5.5 from both sides, we get: 2.2x = 3.85
Dividing both sides by 2.2, we get: x = 1.75
Therefore, Manuel purchased 1.75 pounds of corn kernels.

Which of the following is the surface area of the pyramid?
36 m2
72 m2
88 m2
144 m2
please answer quick, give quick explanation please:) thanks!! 60 points!
Answers
The Surface area of Pyramid is equal to Option (B) [tex]72 m^2[/tex] when base is square and their are 4 triangles.
The surface area of a pyramid is the total area of all its faces. The formula to calculate the surface area of a pyramid depends on the shape of its base.
To find the surface area of this pyramid we should add area of all 4 triangles and 1 square base.
Area of Base = 4m * 4m
= [tex]16m^2[/tex]
Area of Triangle = 1/2 *4* 7
= [tex]14m^2[/tex]
Surface Area of Pyramid = Area of Base + 4 * (Area of Triangle)
= [tex]16m^2 + 4(14m^2)[/tex]
= [tex]72 m^2[/tex]
Therefore, Surface area of Pyramid is equal to [tex]72 m^2[/tex].
