Find the equation for the line that passes through the point (−1,4), and that is parallel to the line with the equation y−5=34(x−2)

Find The Equation For The Line That Passes Through The Point (1,4), And That Is Parallel To The Line

Answers

Answer 1

In point-slope form, the equation of the parallel line to y − 5 = 3/4(x − 2) is: y - 4 = 3/4(x + 1).

What is the Equation of Parallel Lines?

If two lines are parallel their equation, written in point-slope form y - b = m(x - a), will have the same value of m, which is the same slope.

The slope of the line with the equation y - 5 = 3/4(x - 2), is 3/4. This means that the line that passes through the point (−1, 4), and that is parallel to the line with the equation y − 5 = 3/4(x − 2), will have the same slope, m = 3/4.

To write the equation of the line that is parallel to y - 5 = 3/4(x - 2), in point-slope form, substitute m = 3/4 and (a, b) = (-1, 4) into y - b = m(x - a):

y - 4 = 3/4(x - (-1))

y - 4 = 3/4(x + 1)

The equation of the line that is parallel to y − 5 = 3/4(x − 2) is therefore expressed in point-slope form as: y - 4 = 3/4(x + 1).

Isa had planned to buy 2 hardcover and 3 paperback books.
How much more will Isa pay if she buys 2 hardcover and 4 paperback books instead of her original plan? Enter the answer in the box.

Answers

The extra amount that the store would have to pay for buying 2 hardcover and 4 paperback books instead of her original plan is $1.51

How to solve for the amount of books bought

The paper back books have a discount of 25%

hence we what would be paid for in such category would be 1 - 25% charge = 75 %

price of hardcover = 17.95

price of paperback = 9.95 dollars

Isa bought 2 hardcover and 4 paper back

we are to find the cost of these items

2 x 17.95 + (4 x 9.95 x 75%)

= 35.9 + 29.85

= 65.75

We have to find the cost of the initial plan of  2 hardcover and 3 paperback books.

2 x 17.95 + 3 x 9.95 x 0.75

35.9 + 22.3875

= 58.29

This is less than 59 dollars, she would have to pay the shipping fee.

58.29 +  $5.95

= 64.23

find the inverse of

f(x) = 4x + 2 over 3​

Answers

Answer: f^-1(x)=(3x-2)/4

Step-by-step explanation:

1. Change the x and y

y=(4x+2)/3 → x=(4y+2)/3

2. Swap sides (optional)

x=(4y+2)/3 → (4y+2)/3=x

3. Multiply the equation by 3 on both sides

(4y+2)/3=x → (3)*(4y+2)/3=x*(3)

4. Subtract 2 from both sides

(3)*(4y+2)/3=x*(3) → 4y=3x-2

5. Divide 4 from both sides

4y=3x-2 → y=(3x-2)/4

6 Substitute f^-1(x) for y

y=(3x-2)/4 → f^-1(3x-2)/4

A farmer purchased 480 meters of fencing, and will build a rectangular pen with it. To enclose the largest possible area, what should the
pen's length and width be? Model the pen's area with a function, and then find its maximum value.

To enclose the largest possible area, the pen's length should be__and width should be__.

Answers

The largest possible area will be 14400 meters², the pen's length should be 120 meters, and the width should be 120 meters.

What is the perimeter of the rectangle?

The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.

Let's assume that the length of the pen would be x.

We have been given the perimeter as 480 meters.

Let w be the width of the rectangle  and l be the length of the rectangle

The perimeter of a rectangle = 2(l+w)

So, 480= 2(x + w)

240 = x + w

w = 240 - x

Length = x and width = (240 – x)

Area = x(240 - x) = 240x - x²

To get the maximum area, we equate the first derivative of the area to zero.

A = 240x - x²dA/dx = 240 - 2x = 0

2x = 240

x = 120

So, width = 240 – x = 240 – 120 = 120.

Maximum area = length × width

Maximum area = 120 × 120 = 14400 meters²

Thus, the pen should be 120 meters long and 120 meters wide, with a maximum possible area of 14400 meters².

A Maclaurin series is given by f(x),

We need to do to get the desired polynomial is to calculate the derivatives, evaluate them at the given point, and plug the results into the given formula.

f⁽⁰⁾(x) = f(x) =sin(3x²)

Evaluate the function at the point: f(0)=0

1st derivative: f(1)(x)=(sin(3x²))′ = 6xcos(3x²)

1st derivative at the given point: (f(0))′=1

2nd derivative: f(2)(x)=(f(1)(x))′=(6xcos(3x²))′=−36x2sin(3x2)+6cos(3x²)  

Evaluate the 2nd derivative at the given point: (f(0))′′=6

3rd derivative: f(3)(x)=(f(2)(x))′=(6xcos(3x²))′=−36x2sin(3x²)+6cos(3x²)  

Evaluate the 3rd derivative at the given point: (f(0))′′′=0

Liam is setting up folding chairs for a meeting. If he arranges the chairs in 7 rows of the same length, he has 5 chairs left over. If he arranges the chairs in 5 rows of that same length, he has 17 left over. How many chairs does Liam have?

Answers

Answer: 47

Step-by-step explanation: Let's call the number of chairs Liam has x. We can set up the following equations to represent the problem:

7r = x - 5

5r = x - 17

Where r is the length of each row.

To solve for x, we can set the two equations equal to each other:

7r = x - 5

5r = x - 17

Then we can solve for x by combining like terms and solving for the value of x:

7r - 5r = x - 5 - x + 17

2r = 12

r = 6

We can substitute the value of r back into either of the original equations to solve for x:

7r = x - 5

7 * 6 = x - 5

x = 47

Therefore, Liam has 47 chairs.

Answers

The average rate of change of the function on the interval from x = 3 to x = 5 is 40.

What is meant by average rate of change?

In mathematics, the average rate of change is a measure of how much a dependent variable (such as y) changes in proportion to a change in the independent variable (such as x). It is calculated by dividing the change in the dependent variable by the change in the independent variable during a certain time period. If the value of y rises by 5 units when the value of x rises by 2 units, the average rate of change is 5/2 Equals 2.5 per unit change in x. Calculus students frequently use this idea to compute the slope of a line on a graph or to calculate the rate at which a function changes. It is a crucial idea in several domains.

How to solve?

f(x) = 10(2)x,the interval is from x = 3 to x = 5

At x = 3,  10(2)3 = 80

at x = 5, 10(2)5 = 160

total change over the interval from x = 3 to x = 5 is 160 - 80 = 80.
