Answers

Answer: y=4x+8

Step-by-step explanation:

The slope-intercept form of the line is y=4x+8.

What is the slope-intercept form of the line?

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

The given equation is 12x – 3y= –24. The slope-intercept form of the equation will be written as,

12x – 3y= –24

3y = 12x + 24

y = 4x + 8

Therefore, the slope-intercept form of the line is y=4x+8.

together tomas and ana weigh 145 kilograms. ana and rodrigo together weigh the same as tomas. rodrigo weighs 39 kilograms. how many kilograms does tomas weigh?

Answers

Tomas and Ana weigh 145 kilograms combined. Together, Ana and Rodrigo weigh the same as Tomas. Rodrigo is 39 kilograms in weight. Tomas is 92 kilograms in weight.

A mathematical statement with two equated algebraic expressions is known as an algebraic equation. Due to the presence of polynomials on both sides of the equal sign, an algebraic equation is also referred to as a polynomial equation.

A linear algebraic equation has a polynomial of degree 1 in it. A linear equation's most common form is a1x1+a2x2+...+anxn = 0, where at least one coefficient is a number that is not zero. Linear programming problems can be represented and solved with these linear equations.

Let X and Y represent Anna's weight and Tomas's.

Now,

$X+Y=145 ............equation 1\\Y+39=X ..............equation2$

We obtain this by transferring the value of X from equation 2 to equation 1,

$Y+39+Y=145\\2Y+39=145\\2Y=145-39\\2Y=106\\Y=\frac{106}{2}\\ Y=53$

Now that we have entered the value of Y into equation 2, we get:

$53+39=92$

Therefore, Tomas weighs 92 kilograms.

6) Bill is three times older than Kevin. He is also 28 years older than Kevin. How old are they?

Answers

Answer:

If bill is 28 years older than him, but also 3 times older than him, then you divide 28 by 3, which gives you 9.3. So that means kevin is around 9 1/4 years old and bill is around 37 and 1/4 years old, but you dont ahve to count the fraction if you dont want to, all that matters is the whole number.

Step-by-step explanation:

Bill is 42, while Kevin is 14 years old

Represent Bill's age with B, and Kevin's age with K.

So, we have the following equations

B = 3K and B = 28 + K

Substitute 3K for B in the second equation

$3K = 28 + K$

Collect like terms

$-K + 3K = 28$

$2K = 28$

Divide both sides by 2

$K = 14$

Substitute 14 for K in the first equation

$B =3 \times 14$

$B =42$

Hence, Bill is 42, while Kevin is 14 years old

water is flowing at the rate of 50m3/min from a shallow concrete conical reservoir (vertex down)of base radius 45m and height 6m. how fast is the water level falling when the water is 5m deep?

Answers

The water level in a shallow concrete conical reservoir (vertex down) with base radius 45m and height 6m is falling at a rate of approximately 0.54m/min when the water is 5m deep.

To solve this problem, we can use the related rates formula, which states that the rate of change of one variable with respect to time is equal to the product of the rate of change of another variable with respect to time and the derivative of the first variable with respect to the second variable. In this case, we want to find the rate of change of the water level (h) with respect to time (t) when the water depth (y) is 5m. We start by finding the volume of the water in the reservoir as a function of the water depth. Since the reservoir is in the shape of a cone, we have V = $(1/3)πr^2h$, where r is the base radius of the cone and h is the height of the water level. We can solve this equation for h to get h = $(3V)/(πr^2)$.

Next, we differentiate both sides of this equation with respect to time to obtain$dh/dt = (3/πr^2)dV/dt$. To find $dV/dt$, we note that the water is flowing out of the reservoir at a constant rate of 50 m^3/min. Therefore, dV/dt = -50 m^3/min. Substituting this value and the given values of r and h, we obtain $dh/dt = -(9/π)(5/3)^2/[(45/3)^2(5 - 5/3)$] ≈ 0.54 m/min.

The perimeter of a rectangular toddler play area is 62 feet. The length is nine less than three times the width. Find the length and width of the play area. The length of the play area is: feet. The w

Answers

The length of the play area is 21 feet, and the width of the play area is 10 feet. The length of the play area is: 21 feet. The width of the play area is: 10 feet.

A rectangular toddler play area has a length and width. The perimeter of the rectangular toddler play area is the sum of all its sides. Therefore, the perimeter of the rectangular toddler play area is equal to: 2(L + W) = 62, where L is the length and W is the width.

Since the length of the rectangular toddler play area is 9 less than three times the width, it can be written as:

L = 3W - 9.

To find the length and width of the rectangular toddler play area, we need to solve for L and W by substitution. Substitute L = 3W - 9 into the perimeter equation:

2(L + W)

= 62:2(3W - 9 + W)

= 62Simplify: 2(4W - 9) = 62

Simplify further: 8W - 18 = 62

Add 18 to both sides of the equation: 8W = 80

Solve for W by dividing both sides by 8: W = 10

Substitute W = 10 into L

= 3W - 9: L

= 3(10) - 9

= 30 - 9

= 21

The length of the play area is 21 feet, and the width of the play area is 10 feet. The length of the play area is: 21 feet. The width of the play area is: 10 feet.

suppose we wish to use the chi-squared test of independence to examine whether there is a relationship between two categorical variables. the contingency table we have has 3 rows and 7 columns, and we have a total sample size of 270. what degrees of freedom would we use, assuming we had a table big enough that would let us look up any value?

Answers

Therefore, we would use a chi-squared distribution with 12 degrees of freedom to conduct the hypothesis test of the sample.

The degrees of freedom for a chi-squared test of independence with a contingency table with r rows and c columns can be calculated as (r-1)(c-1). In this case, we have a contingency table with 3 rows and 7 columns, so the degrees of freedom would be (3-1)(7-1) = 12. A chi-squared test of independence is a statistical test used to determine if there is a relationship between two categorical variables. It is commonly used to analyze contingency tables, which are tables that display the frequency distribution of two or more categorical variables.

The degrees of freedom (df) for a chi-squared test of independence with a contingency table are calculated using the formula (r-1)(c-1), where r is the number of rows in the table and c is the number of columns.

In this case, we have a contingency table with 3 rows and 7 columns. Therefore, r = 3 and c = 7.

Substituting these values into the formula, we get:

df = (r-1)(c-1)

so far i've written :
The direction in which it travels is given by the arctan(y/x)=
arctan(-4/3) = -53.13 degrees = 36.87 degrees

Answers

the boat is traveling in the direction of 68.2 degrees from the positive x-axis.

What is vector?

In mathematics, a vector is a mathematical object that has both magnitude and direction. Vectors are commonly used to represent physical quantities such as velocity, acceleration, and force. A vector can be represented by an arrow, where the length of the arrow represents the magnitude of the vector, and the direction of the arrow represents the direction of the vector.

Given by the question.

The direction in which it travels is given by the arctan(y/x)=

arctan (-4/3) = -53.13 degrees = 36.87 degrees

To find the speed of the boat, we need to calculate the magnitude of the vector b, which represents the boat's velocity. Using the Pythagorean theorem, we can find the magnitude of b as follows:

|b| = sqrt ($(-2)^{2}$ +$(-5)^{2}$) = sqrt (4 + 25) = sqrt (29)

Therefore, the speed of the boat is approximately 5.39 meters per second.

To determine the direction of the boat in standard position, we use the arctan function to find the angle between the vector b and the positive x-axis. The angle can be calculated as:

theta = arctan (-5/-2) = arctan (2.5) = 1.19 radians or 68.2 degrees (rounded to one decimal place).

Answers

Option D, U = 4L + T, is the best choice for maximizing the consumer's utility.

Which utility function results in the highest consumer satisfaction?

Among the given options for the consumer's utility function, option D, U = 4L + T, provides the optimal choice for maximizing utility.

In this utility function, the consumer assigns a weight of 4 to lettuce (L) and a weight of 1 to tomatoes (T).

By maximizing the number of salads made, the consumer can increase both L and T, resulting in higher overall utility.

The utility function directly reflects the consumer's preference for a higher quantity of lettuce relative to tomatoes.

Therefore, option D, U = 4L + T, allows the consumer to obtain the highest satisfaction by appropriately balancing the quantities of lettuce and tomatoes in their salads.
