√3x+4 = 1+√3x-11 When both sides of the equation are squared, the resulting equation is

Answers

The resulting equation is 14√3x - 47 = 0.

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 8 is an equation.

We have,

√3x + 4 = 1 + √3x -11

√3x + 4 = √3x - 10

Squaring both sides

(√3x + 4)² = (√3x - 10)²

3x² + 16 + 8√3x = 3x² - 20√3x + 100

16 - 100 + 8√3x + 20√3x = 0

28√3x - 94 = 0

2(14√3x - 47) = 0

14√3x - 47 = 0

Thus,

14√3x - 47 = 0 is the resulting equation.

pounds. Let x represent how old the baby is in weeks and y represent the baby's weight in
pounds. Find the equation of the line that goes through these two points.

Answers

From given data, equation of line will be x - 2y = -16.

Find the equation of the line that goes through these two points?

To find points on the line y = mx + b, choose x and solve the equation for y, or. choose y and solve for x.

The two-point form of a line is used for finding the equation of a line given two points (x1,y1) ( x 1 , y 1 ) and (x2,y2) ( x 2 , y 2 ) on it. The two point-form of a line is:y−y1=y2−y1x2−x1(x−x1) y − y 1 = y 2 − y 1 x 2 − x 1 ( x − x 1 ) OR y−y2=y2−y1x2−x1(x−x2) y − y 2 = y 2 − y 1 x 2 − x 1 ( x − x 2 ) .

It's called this because it clearly identifies the slope and the y-intercept in the equation. The slope is the number written before the x. The y-intercept is the constant written at the end. Let's look at an example: y = 3x + 2.

Given,

x represent how old the baby is in weeks

y represent the baby's weight in pounds.

At 2 weeks old, baby Nellie weighed 9 pounds. When she was 8 weeks old, she weighed 12 pounds.

⇒ (2,9)

Answers

The number of casual jeans sold was 81 and the number of dress jeans sold was 40.5 (rounded to 41).

Calculating Casual & Dress Jeans Sold

Let's call the number of casual jeans sold "x". Then the number of dress jeans sold would be "x/2".The total revenue from the casual jeans would be $45 * x and the total revenue from the dress jeans would be $55 * x/2.We know that the total revenue was $4,060, so we can set up the following equation:

        $45x + $55x/2 = $4,060

Expanding the second term:

        $45x + $55x/2 = $4,060

        $45x + $55x/2 = $4,060

        $100x/2 = $4,060

        $100x = $8,120

Dividing both sides by $100:

        x = 81

So from above calculation, we got that the number of casual jeans sold was 81 and the number of dress jeans sold was 81/2 = 40.5 (rounded to 41).

Use the Binomial Theorem and substitution to expand each Binomial. Show your step.

A) (3x+y)^4
B) (x-2y)^6

Answers

Answer:

A) (3x + y)^4:

The Binomial Theorem states that for any real numbers a and b, and any positive integer n, the expansion of (a + b)^n is given by the sum of n terms of the form:

C(n,k)a^(n-k)b^k

where C(n,k) is the binomial coefficient (n choose k).

So, expanding (3x + y)^4:

(3x + y)^4 = C(4,0)(3x)^4(y)^0 + C(4,1)(3x)^3(y)^1 + C(4,2)(3x)^2(y)^2 + C(4,3)(3x)^1(y)^3 + C(4,4)(3x)^0(y)^4

Using the binomial coefficients:

C(4,0) = 1, C(4,1) = 4, C(4,2) = 6, C(4,3) = 4, C(4,4) = 1

Expanding the terms:

(3x + y)^4 = 1(3x)^4(y)^0 + 4(3x)^3(y) + 6(3x)^2(y)^2 + 4(3x)(y)^3 + 1(y)^4

= 1(81x^4) + 4(27x^3y) + 6(9x^2y^2) + 4(3xy^3) + 1(y^4)

= 81x^4 + 108x^3y + 54x^2y^2 + 12xy^3 + y^4

B)

The Binomial Theorem states that for any real numbers a and b and any positive integer n, the expansion of (a + b)^n is given by:

(a + b)^n = C(n, 0)a^n * b^0 + C(n, 1)a^(n-1) * b^1 + C(n, 2)a^(n-2) * b^2 + ... + C(n, n-1)a^1 * b^(n-1) + C(n, n)a^0 * b^n

where C(n, k) represents the binomial coefficient, which can be calculated as n! / (k! (n - k)!).

Applying this to (x - 2y)^6, we get:

(x - 2y)^6 = C(6, 0)x^6 * (-2y)^0 + C(6, 1)x^5 * (-2y)^1 + C(6, 2)x^4 * (-2y)^2 + ... + C(6, 5)x^1 * (-2y)^5 + C(6, 6)x^0 * (-2y)^6

Expanding each term:

C(6, 0) = 6! / (0! 6!) = 1

C(6, 1) = 6! / (1! 5!) = 6

C(6, 2) = 6! / (2! 4!) = 15

C(6, 3) = 6! / (3! 3!) = 20

C(6, 4) = 6! / (4! 2!) = 15

C(6, 5) = 6! / (5! 1!) = 6

C(6, 6) = 6! / (6! 0!) = 1

Now we can substitute each value into the equation:

(x - 2y)^6 = 1x^6 - 12x^5 * 2y + 90x^4 * (-2y)^2 - 360x^3 * (-2y)^3 + 720x^2 * (-2y)^4 - 720x * (-2y)^5 + 1 * (-2y)^6

Answer:

(x - 2y)^6 = x^6 - 12x^5 * 2y + 90x^4 * (-2y)^2 - 360x^3 * (-2y)^3 + 720x^2 * (-2y)^4 - 720x * (-2y)^5 + (-2y)^6.

cost price of a torchlight is rs.1400 its mp is 40% more than cost price if the shopkeeper sells it at 20% discount what is marked price of the torch​

Answers

Answer:

The marked price of the torchlight is Rs. 1960.

Step-by-step explanation:

The marked price (MP) of a torchlight is 40% more than the cost price (CP), so we can calculate the MP using the formula:

MP = CP + (CP x 40%)

The cost price of the torchlight is Rs. 1400, so the marked price is:

MP = 1400 + (1400 x 40%) = 1400 + 560 = 1960

The shopkeeper is selling the torchlight at a 20% discount, so we can calculate the selling price (SP) using the formula:

SP = MP - (MP x 20%)

The marked price of the torchlight is Rs. 1960, so the selling price is:

SP = 1960 - (1960 x 20%) = 1960 - 392 = 1568

So the marked price of the torchlight is Rs. 1960.

Step-by-step explanation:

Elaine spent 6.30 + px dollars on her purchase and Elena spent 4.15 + 4p dollars on her purchase. To find how much more Elaine spent, we can subtract Elena's total cost from Elaine's total cost: (6.30 + px) - (4.15 + 4p) = (6.30 - 4.15) + (px - 4p) = 2.15 + (px - 4p) = 2.15 + p*x - 4p.

The complement of 0.87 is calculated by subtracting the given number from 1. Mathematically, this can be expressed as 1 - 0.87 = 0.13.

The complement of any number x is calculated by subtracting x from 1. This means that the complement of 0.87 is 0.13.

The complement of a number is used to find the remaining portion of a whole. For example, if the given number is 0.87, then the complement of 0.87 is 0.13. This means that 0.87 is 87% of the whole and 0.13 is the remaining 13%. Thus, the complement of 0.87 is 0.13.

Complements can also be used to find the probability of something happening. For example, if the probability of an event occurring is 0.87, then the probability of it not occurring is 0.13. This is because the sum of the probabilities must equal 1 (100%). Therefore, the complement of 0.87 is 0.13.

Answers

To solve for the length and the breadth of the rectangle, we can use the Pythagorean Theorem. By substituting the given values into the theorem, we get that the equation 2x² - 16x + 30 = 0. Therefore, using the quadratic formula, x = 8 ± √34/2. Since the length of the long side is 8 cm, we can calculate the breadth as b = 8 ± √34/2 - 8 = 5.83 ± √34/2 - 5.83. Therefore, the length and breadth of the rectangle are 8 cm and 5.83 cm respectively.

the perimeter of a square and rectangle are equal. if the sides of the rectangle are 12cm and 10cm,find the area of the square

Answers

Answer: The length of one side of the triangular-shaped walking path is 330 feet.

Step-by-step explanation:

The perimeter of the triangular-shaped walking path is 990 feet, and the length of one side is represented by x. We can write an equation to find x using the formula for the perimeter of a triangle:

P = a + b + c

Where P is the perimeter, and a, b, and c are the lengths of the sides of the triangle. Since one of the sides is represented by x, the equation can be written as:

990 = x + x + x

Simplifying the equation, we can find the value of x:

990 = 3x

Dividing both sides by 3, we get:

330 = x

So the length of one side of the triangular-shaped walking path is 330 feet.

To figure out the answer, first find the perimeter of the rectangle (10+10+12+12 = 44). Now that we know the perimeter of the rectangle, and that the square has the same perimeter, we can divide 44/4, to get 11. Now that we know the side length of the square, we can do 11 x 11 = 121.

Answer:

The rate of interest per annum is 3%.

Step-by-step explanation:

The rate of interest per annum is 3%.

This can be calculated using the formula:

Simple Interest = (Principal x Rate x Time) / 100

In this case, we know that the Simple Interest = $54 and the Principal = $800, Time = 3 years.

So, we can rearrange the formula to solve for the Rate:

To estimate the average age of an employee in 2003, we need to find the value of A(s) when s = 22  ;

because the number of years between 2003 and 1981 is = 22 years ;

So , A(22) = 0.285×22 + 59 = 65.27  ;

The average age of an employee in 2003 is approximately 65.27.

To estimate the average age of an employee in 2009,

we need to find the value of A(s) when s = 28

because the number of years between 2009 and 1981 is = 28 years ;

So , A(28) = 0.285×28 + 59 = 66.98  ;

The Average age of employee in 2009 is approximately 71.48.

In circle F, the measure of ∠AFE is equal to 150° and the measure of arc BD is equal to 50°.

What is the measure of ∠C?

Answers

The measure of ∠C found using central angle and intercepted angle relationship is 50°.

What is central angle and intercepted arc of a circle?

An angle with its vertex at the circle's centre and both of its endpoints are on circle is said to be central angle. The angle's intercepted arc's ends are the same as the circle's endpoints. A circle's circumference includes an arc. Therefore, an intercepted arc is an arc that is created when one or more chords or line segments intersect a circle and come together at a vertex.

An important feature to remember when looking for missing arcs or central angles is that the angle measure of the central angle is equal to the measure of the intercepted arc.

Given,

∠AFE = 150°

arc BD =  50°

External angle formed outside a circle,

= 1/2 ( major arc -  minor arc )

Major arc = intercepted arc AE =  central angle ∠AFE = 150°

Minor arc = arc BD =  50°

Therefore external angle ∠C = 1/2(150-50) = 50°

Hence 50° is the measure of ∠C.

Answer:

B

Step-by-step explanation:

[tex]x = \frac{2}{3}\pi r^{3}[/tex]

The objective is to isolate r and make r the subject of the equation:

Cross-multiplication is applied:

[tex]= 2\pi r^{3}= 3x[/tex]

The variables and number multiplied with [tex]r^{3}[/tex] are transferred to the other side of the equation:

[tex]= \pi r^{3} = \frac{3x}{2}[/tex]

[tex]= r^{3} = \frac{3x}{2\pi}[/tex]

Cube root is applied to both sides of the equation to get rid of the cube:

[tex]= \sqrt[3]{r^{3}} = \sqrt[3]{\frac{3x}{2\pi}}[/tex]

[tex]r = \sqrt[3]{\frac{3x}{2\pi}}[/tex]

How to define the linear function?

The slope-intercept definition of a linear function is given as follows:

y = mx + b.

In which:

The slope m represents the rate of change of the output variable relative to the input variable.The intercept b represents the value of y when the graph of the function touches of crosses the y-axis.

The parallel line is defined as follows:

3x - y + 1 = 0.

In slope-intercept format, it is given as follows:

y = 3x + 1.

Hence the slope of line a is given as follows:

m = 3.

(as parallel lines have the same slope).

The intercept is the same as the line 11x + 3y + 6 = 0, hence:

3y + 6 = 0

3y = -6

y = -2

b = -2.

Hence the line a is defined as follows:

y = 3x - 2.

What is the slope of a line perpendicular to 10x + 4y = 20? a. −4
b. −4/10
c. −10/4
d. 10/4
e. 4/10

Answers

Correct option is E, The slope of a line perpendicular to y = -10/4 x + 5 is 4/10

What is the slope of a line perpendicular?

The slope of the parallel line is undefined and the slope of the perpendicular line is 0.

Yes, the slope of a line perpendicular to the line 10x + 4y = 20 is indeed -4.

To find the slope of a perpendicular line, we can find the negative reciprocal of the slope of the original line.

The slope of line 10x + 4y = 20 can be found by solving for y and writing the line in slope-intercept form (y = mx + b), where m is the slope.

By solving for y in the equation 10x + 4y = 20:

10x + 4y = 20

4y = -10x + 20

y = -10/4 x + 20/4

y = -10/4 x + 5

So the line is in the form y = -10/4 x + 5, which is the slope-intercept form of a line where the slope (m) is -10/4 and the y-intercept (b) is 5.

Now, to find the slope of a line perpendicular to this line, we need to find the negative reciprocal of the slope of this line. The negative reciprocal of -10/4 is 4/10.

hence,. the slope of a line perpendicular to y = -10/4 x + 5 is 4/10
