Lila wrote an equation of the cost for printing brochures, where x represents the number of brochures and y represents the total cost. The total cost for 35 brochures is $41.45. The total cost for 65 brochures is $55.55. Step 1: Write the ordered pairs (35, 41.45) and (65, 55.55). Step 2: Find the slope. M = StartFraction 55.55 minus 41.45 Over 65 minus 35 EndFraction = 0.47 Step 3: Find the y-intercept to write the equation in slope intercept form. Y minus 55.55 = 0.47 (x minus 35). Y minus 55.55 = 0.47 x minus 16.45. Y = 0.47 x + 39.1. Which explains the error that Lila made? Lila made in error in Step 1 by reversing the ordered pairs. Lila made an error in Step 2 by not using the slope formula. Lila made an error in Step 3 when she did not use the x- and y-coordinates from the same ordered pair. Lila made an error in Step 3 when she did not use the distributive property correctly when multiplying.
Answer:
The answer is C. Lila made an error in Step 3 when she did not use the x- and y-coordinates from the same ordered pair.

The y intercept of the problem is equal to 25+14.1/30*x.
What is total cost?The total cost is the sum of the fixed cost and the variable cost to make a product.
How to find y-intercept?x is showing no. of bruchers
y is showing total cost.
Total cost for 35 bruchers=41.45
Total cost for 65 bruchers=55.55
The points are (35,41.45), (65,55.55)
The y intercept can be calculated as :
y-41.45=(55.55-41.45/65-35)*(x-35)
30y-14.1x=750
y=25+14.1/30*30

Write a system of equations for the coefficients of a polynomial of degree 2 that passes through (1, - 2), (- 2, 7) and (- 5, - 2) Solve the system.
The system of equations is:
-2 = a + b + c
7 = 4a - 2b +c
-2 = 25a + 5b + c
The polynomial is:
y = (1/3)*x^2 - 6x - 1/3
How to write and solve the system of equations?The general polynomial of degree 2 can be written as:
y = a*x^2 + b*x +c
If we use the fact that it passes through the 3 given points, then we can write the 3 equations:
-2 = a*1^2+ b*1 + c
7 = a*(-2)^2 + b*-2 + c
-2 = a*5^2 + b*5 + c
We can simplify these to get the system of equations:
-2 = a + b + c
7 = 4a - 2b +c
-2 = 25a + 5b + c
First, isolate c on the first equation to get:
c = -2 - a- b
Replace it on the other two:
7 = 4a - 2b + (-2 - a - b)
-2 = 25a + 5b + (-2 - a - b)
9 = 3a - 3b
0 = 24a + 4b
Using the second equation we can rewrite:
-24a = 4b
-24a/4 = b
-6a = b
Ande replace that in the other equation:
9 = 3a - 3*(-6a)
9 = 3a + 18a
9/21 = a
1/3 = a
And the value of b is:
-6*(1/3) = b
-2 = b
And the value of c is:
c = -2 - (-2) - 1/3
c = -1/3
The polynomial is:
y = (1/3)*x^2 - 6x - 1/3

a helium filled balloon has a volume of 50.0 l at 25 and 1.08 atm what volume will it have at .855 atm and 10.0 c
The volume of the helium-filled balloon at 0.855 atm and 10.0 °C will be approximately 42.81 L, calculated using the ideal gas law equation.
To compute this problem, we can use the ideal gas law, which states that PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature in Kelvin.
First, we need to convert the initial temperature of 25 °C to Kelvin:
T1 = 25 + 273.15 = 298.15 K
Next, we can rearrange the ideal gas law equation to solve for V2:
V2 = (P1 * V1 * T2) / (P2 * T1)
We have:
P1 = 1.08 atm (initial pressure)
V1 = 50.0 L (initial volume)
P2 = 0.855 atm (final pressure)
T2 = 10.0 °C (final temperature)
Converting the final temperature to Kelvin:
T2 = 10 + 273.15 = 283.15 K
Substituting the values into the equation:
V2 = (1.08 * 50.0 * 283.15) / (0.855 * 298.15)
V2 ≈ 42.81 L
Therefore, the volume of the helium-filled balloon at 0.855 atm and 10.0 °C will be approximately 42.81 L.

Which is more affected by extreme observations, the mean or median? and how about the standard deviation or iqr?
Mean and standard deviation is more affected by extreme observations.
Mean is the summation of all the values divided by the total number of values. It is also called as average. Median is the middle value.Standard deviation is the dispersion of a dataset relative to its mean. In case of extreme items arithmetic mean is affected very much. For this reason, it no longer remains representative of the distribution. As standard deviation is the positive square root of the arithmetic mean of the square of deviations of all given values, it is also affected by extreme items. As median is a partition value, it is not affected by extreme items.

Triangle XYZ has coordinates X(2, 4), Y(−3, 4), and Z(−3, 1). If the triangle is translated using the rule (x, y) → (x − 2, y + 1), what are the coordinates of Y'?
Y'(–5, 5)
Y'(0, 5)
Y'(–5, 2)
Y'(–1, 3)
Answer:
Y'(-5, 5)
Step-by-step explanation:
To find the coordinates of Y' after the translation, we apply the given rule to the coordinates of point Y(-3, 4).
Using the translation rule (x, y) → (x - 2, y + 1), we can substitute the coordinates of Y(-3, 4) into the rule:
x' = x - 2 = -3 - 2 = -5
y' = y + 1 = 4 + 1 = 5
Therefore, the coordinates of Y' are (-5, 5).
Use implicit differentiation to find
∂z/∂x and ∂z/∂y.
x2 + 4y2 + 9z2 = 4
The partial derivatives using implicit differentiation are:
∂z/∂x = -x / (9z)
∂z/∂y = -4y / (9z)
To find the partial derivatives ∂z/∂x and ∂z/∂y using implicit differentiation, we start with the given equation:
x^2 + 4y^2 + 9z^2 = 4
First, we differentiate both sides of the equation with respect to x:
2x + 0 + 18z(∂z/∂x) = 0
Now, solve for ∂z/∂x:
18z(∂z/∂x) = -2x
∂z/∂x = -2x / (18z)
∂z/∂x = -x / (9z)
Next, we differentiate both sides of the equation with respect to y:
0 + 8y + 18z(∂z/∂y) = 0
Now, solve for ∂z/∂y:
18z(∂z/∂y) = -8y
∂z/∂y = -8y / (18z)
∂z/∂y = -4y / (9z)
So, the partial derivatives are:
∂z/∂x = -x / (9z)
∂z/∂y = -4y / (9z)

what is the word used to describe a vector that always points toward the center of a circular path?
"Centripetal is the word used to describe a vector that always points toward the centre of a circular path."
The centripetal acceleration vector is an acceleration in the radial direction that is directed towards the centre of the circular line of motion. It runs perpendicular to the linear motion, or v.
The direction of the velocity shift for a ball travelling around a curve is in the direction of the curve's centre. Centripetal acceleration is the acceleration that is directed towards the centre of a curved or circular route.
Any force that changes the path of motion towards the centre of a circular motion is known as a centripetal force. The portion of the force that produces the centripetal force is the part that is perpendicular to the velocity.

the arithmetic sequence x , x , -3 , 2x what is the value of x
Answer:
x, x, -3, 2x cannot be an arithmetic sequence
Step-by-step explanation:
an arithmetic sequence has a constant difference between subsequent elements. That means
x - x = -3 - x = 2x - (-3)
0 = -3 - x = 2x + 3
and we get:
x = -3 ; from 0 = -3 - x
and
x = -3/2 ; from 0 = 2x + 3

How do you calculate obtuse value?.
Calculating the obtuse angle or value of a triangle.
Finding obtuse angle value:
steps:
1) Square the length of both sides of the triangle that intersect to create the obtuse angle, and add the squares together.
For example, if the lengths of the sides measure 4 and 2, then squaring them would result in 16 and 4. Adding the squares together results in 20.
2) Square the length of the side opposite the obtuse angle. For the example, if the length is 5, then squaring it results in 25.
3) Subtract the combined squares of the adjacent sides by the square of the side opposite the obtuse angle. For the example, 25 subtracted from 20 equals -5.
4) Multiply the lengths of the adjacent sides together, and then multiply that product by 2. For the example, 4 multiplied by 2 equals 8, and 8 multiplied by 2 equals 16.
5) Divide the difference of the sides squared by the product of the adjacent sides multiplied together then doubled. For the example, divide -5 by 16, which results in -0.3125.
The obtuse angle value is obtained by inverse of cos:
cos^-1(-0.3125)

Solve for x
Answer:
x = -103/70 or approximately -1.47
Step-by-step explanation:
First, what I would do is get rid of the denominator, 2. You do this by perming the inverse operation to both sides, so you multiply both sides by 2.
Now your equation is: 70(4x+6) = 8
Next what I did was distribute the 70 inside the parentheses:
280x + 420 = 8.
Then you subtract 420 from both sides:
280x = -412
To get x by itself, you have to divide both sides by 280:
x= -412/280 , which simplifies to -103/70 , or can be written as an approximation of -1.47 (rounded to nearest hundredth)

If a matrix A is 5 x 3 and the product AB is 5 x 7, what is the size of B?
The size of the the matrix B if a matrix A is 5x3 and the product AB is 5x7 is B =[3x7].
Two matrices can only be multiplied if the first matrix has the same number of columns as the second matrix has. If the first matrix has dimensions of a x b and the second matrix has dimensions of c x d, then b = c and their product will have dimensions of a x d.
Let A is a 3 x 5 matrix and B is a 5 x 7 matrix
We know that matrix multiplication of A and B is possible if
Number of columns of A = Number of rows of B
Since in the given problem
Number of columns of A = Number of rows of B = 5
So the product is possible
Now the product AB is a matrix of order 3 × 7
Now the order of the product AB is 3 × 7
If a 3 x 5 matrix is multiplied by a 5 x 7 matrix then their product is a matrix of order 3 × 7.
