Answer:

y = 7/6x - 62/3

Step-by-step explanation:

The equation for slope:

y = mx + b

m is the slope and b is the y-intercept

y = 7/6x + b

-9 = 7/6(10) + b

-9 = 35/3 + b

-62/3 = b

We will not be able to figure out the price of one can of each type of canned food in the same manner of operating on two equations.

This is because the equation are identical.

Let the dog food be represented by d.

Let the cat food be represented by c.

Since Carlos buys 4 cans of dog food and 6 cans of cat food for $12.00. This will be:

4d + 6c = 12

This cane b reduced to lowest term as 2d + 3c = 6

Then the next week, he purchased 2 cans of dog food and 3 cans of cat food for $6.00. This will be:

2d + 3c = 6

Since the equations are the same, we can't calculate the price.

The correct option is c.Keep going.

Create a regression model and be able to optimize it, it is much better that all factors are on a scale. The answer is option c.Keep going.Regression analysis is an important statistical method that is commonly used in finance and other fields for prediction purposes. It is useful for finding the relationships between one dependent variable and one or more independent variables. In order to create an efficient regression model, the variables should be measured on a scale. Therefore, it is important to measure variables on a scale, as this makes it easier to create a regression model. If variables are categorical or binary, it becomes difficult to measure their relationship with the dependent variable using regression models as they are not measurable on a scale. This is why it is much better that all factors are on a scale while creating a regression model and optimizing it. Thus, the correct option is c.Keep going.

x (f o g)(x)

-2 7

To find the values of (f o g)(x), we need to substitute the values of g(x) into f(x). The composition (f o g)(x) means that we first apply g(x) to x, and then apply f(x) to the result.

Using the table of values for g(x):

Calculating (f o g)(x):

For x = -2:

(f o g)(-2) = f(g(-2)) = f(4) = 7

For x = -1:

(f o g)(-1) = f(g(-1)) = f(1) = 4

For x = 0:

(f o g)(0) = f(g(0)) = f(0) = 3

For x = 1:

(f o g)(1) = f(g(1)) = f(1) = 4

For x = 2:

(f o g)(2) = f(g(2)) = f(4) = 7

Answer:

One marble (other than red)

Step-by-step explanation:

The total number of marbles is 15 + 18 + 6 + 10 = 49. The probability of drawing a red marble is 10 out of 49. We want to change those odds to 10 out of 50 (or 20%). Therefore, we need to add one marble; any color other than red will work.

Answer:

1 marble needs to be added

Step-by-step explanation:

So we know that there are 15 blue marbles, 18 green, 6 yellow, and 10 red. We are trying to find out how may marbles must be added to the bag so that there is a 1/5 or 20% chance of drawing a red marble. Lets find out how many marbles should be in the bag (NOT added to the bag, we will find that later) so that the chance of drawing a red one is 1/5. To do this, we can make this equation:

\(\frac{10}{T}=\frac{1}{5}\)

Where T is the total number of marbles that should be in the bag. Lets solve this for T:

\(\frac{10}{T}=\frac{1}{5}\)

Cross multiply.

T = (10)(5)

T = 50

So now we know that the total number of marbles that should be in the bag to make the chance of drawing a red 1/5 is 50. Now we can subtract the number of marbles that are currently in the bag from 50 to find the number of marbles to add.

50 - (15 + 18 + 6 + 10) = 50 - 49 = 1

So 1 marbles has to be added so that the chance of drawing a red marble is 1/5.

I hope you find my answer and explanation helpful. Happy studying. :)

Step-by-step explanation:

f(x) = x⁴ + 2

differentiate

f(x) = 4x³ + 0 =0

x(4x²) = 0

at x= 0 f(x) = 0 points = (0,0)

at x= 1. f(x) = 3 points = (4,3)......

The ordered pair is (4,3).

An ordered pair is a composition of the x coordinate (abscissa) and the y coordinate (ordinate), having two values written in a fixed order within parentheses. It helps to locate a point on the Cartesian plane for better visual comprehension. The numeric values in an ordered pair can be integers or fractions.

Given:

f(x) = x⁴ + 2

Now, differentiate the above function for the small values

f(x) = 4x³ + 0 =0

x(4x²) = 0

When x= 0

f(x) = 0

So, the points = (0,0)

when x= 1

f(x) = 3

so, the points = (4,3).

The equation G + S + M = 100 represents the number of pounds of glossy, semi-gloss, and matte paper in a 100-pound package. The cost equation is $5.60G + $4.25S + $3.75M = $480. The semi-gloss and matte paper equation is S + M = 0.5(100) or S + M = 50. This equation can be solved using the row-reduction method.

Let G, S, and M represent the number of pounds of glossy, semi-gloss, and matte paper, respectively, in a 100-pound package. The problem's first sentence yields the equation: G + S + M = 100The costs and amounts are given for glossy, semi-gloss, and matte paper. We can use this information to develop two more equations. First, the cost equation is:$5.50G + $4.25S + $3.75M = $480Multiplying both sides by 100 to eliminate decimals gives:550G + 425S + 375M = 48000Finally, we are given that half the package's weight consists of semi-gloss and matte paper. We can translate this statement into another equation: S + M = 0.5(100)or S + M = 50We can then write the system of equations in the matrix form as follows:[1 1 1; 0 1 1; 550 425 375] [G; S; M] = [100; 50; 48000]Using matrix inverse, we have[G; S; M] = [1 1 1; 0 1 1; 550 425 375]^-1[100; 50; 48000]This equation can be solved using the row-reduction method.

The relative frequency of English majors can be calculated as 3/20 = 0.15 or 15%

The relative frequency of English majors in the sample can be calculated by dividing the number of English majors (which is 3) by the total number of students in the sample (which is 20).
So, the relative frequency of English majors can be calculated as:
3/20 = 0.15 or 15%
This means that out of the 20 students in the sample, 15% of them are English majors.
It's worth noting that relative frequency is a way of expressing the proportion of a particular category or value in a dataset, as a percentage of the total. It is a useful tool for understanding the distribution of data and identifying patterns or trends within it. In this case, we can see that English majors are a relatively small proportion of the sample, compared to economics, math, and psychology majors.

Answer:Range

Step-by-step explanation:the set of all images of the elements in the domain of a function is called the Range .

The set of all images of the elements in the domain of a function is called the range. The range is the set of all possible outputs or y-values that a function can produce for its corresponding inputs or x-values in the domain.

The range can be determined by either analyzing the function algebraically or by graphing it. It is important to note that not all functions have a defined range, as some may produce infinite or undefined outputs. The range plays a crucial role in understanding the behavior and characteristics of a function, as it helps identify its domain and any possible restrictions or limitations.

The set of all images of the elements in the domain of a function is called the range of the function. The range represents the output values of a function that result from applying the function to every element within its domain. In other words, the range consists of all possible values that the function can produce when it is applied to the elements in its domain.

Answer: 42650

Step-by-step explanation:

The tens place is behind the ones place.

The number in the tens place in 42653 is 5.

So to round to the nearest tens you have to change three to 0 because if the number in the ones place is 5 or more, then the number in the tens place would be 1 higher than it used to be while the number in the ones place turns to 0.

However if the number in the ones place is less than 5, then that's the only thing that changes, the ones place would change into a '0.'

Hope that helped!

42650 is the value of the 426563 when rounded to the nearest ten.

The value a digit in a number represents based on where it is in the number is known as place value.

Given, the number 42653 which is rounded to the nearest ten value needs to find. Since,

The one's place is in front of the tens place.  In the number 42653, the tens place value is 5. The number three must be changed to 0 in order to round to the next tens because, if the number in the one's place is 5 or greater, the number in the ten's place would be 1 higher than it was previously while the number in the one's place would become 0. The one's place would change to a "0" if the number in the one's place is less than 5, but that is all that changes.

Answer:

f(x) = (x + 4)^2 - 5

Step-by-step explanation:

Parent function: f(x) = x^2

To show this in a way that may look more familiar, f(x) = 1(x - 0)^2 + 0

Vertex form: f(x) = a(x - h)^2 + k

We know a = 1, because the slope is the same as the parent function.

Vertex: (h,k)

We can see that the vertex of the graph is (-4, -5)

So h = -4 and k = -5

Now all we need to do is plug the variables into our equation.

f(x) = a(x - h)^2 + k

f(x) = 1(x + 4)^2 - 5

f(x) = (x + 4)^2 - 5

To write Acos(?0t) + Bsin(?0t) in the form r*sin(?0t - ?), we can use the identities. The relationship among R, r, ? and ? is:
R^2 = r^2 (1 + (A/B)^2), tan? = r/R = B/A

r = sqrt(A^2 + B^2)
tan? = B/A

Therefore, r = sqrt(A^2 + B^2) and tan? = B/A.

To determine the relationship among R, r, ? and ?, we can use the identity:

R^2 = r^2 + (tan?)^2

Therefore, R = sqrt(r^2 + (tan?)^2) and tan? = r/R. Substituting the expression for tan? from earlier, we get:

tan? = B/A = r/R

Solving for R, we get:

R = r/tan? = r/(B/A) = rA/B

And substituting the expression for R in terms of r and tan?, we get:

R = sqrt(r^2 + (r/R)^2) * A/B

Simplifying this expression, we get:

R^2 = r^2 + (A/B)^2 * r^2

R^2 = r^2 (1 + (A/B)^2)

Therefore, the relationship among R, r, ? and ? is:

R^2 = r^2 (1 + (A/B)^2)
tan? = r/R = B/A

To show that Acos(ω₀t) + Bsin(ω₀t) can be written in the form r*sin(ω₀t - θ), we can use trigonometric identities. We know that:

sin(a - b) = sin(a)cos(b) - cos(a)sin(b)

Comparing this to the given expression, we have:

Acos(ω₀t) + Bsin(ω₀t) = r*sin(ω₀t - θ) = r[sin(ω₀t)cos(θ) - cos(ω₀t)sin(θ)]

Now, let's equate the coefficients of sin(ω₀t) and cos(ω₀t):

A = -r*sin(θ)
B = r*cos(θ)

To find r and θ in terms of A and B, we can use the Pythagorean identity:

A² + B² = (-r*sin(θ))² + (r*cos(θ))² = r²(sin²(θ) + cos²(θ)) = r²

Therefore, r = √(A² + B²).

Now, to find θ, we can use the tangent function:

tan(θ) = -A/B

Now, for the second part, if Rcos(ω₀t - θ) = r*sin(ω₀t - θ), we can use the sine-to-cosine transformation:

Rcos(ω₀t - θ) = Rsin(ω₀t - θ + π/2)

This implies that:

R = r
θ + π/2 = θ'

So, the relationship among R, r, θ, and θ' is:

R = r
θ' = θ + π/2
