The elimination method is a technique used to solve linear equations that comprise a system. The fundamental principle behind this methodology involves nullifying one of the variables.

It should be noted that to implement the elimination approach successfully, we must exclude either x or y, which can be accomplished by multiplying the second equation by an amount necessary to make the coefficient of y consistent in both the equations:

With x's value now discerned, we can insert it into any of the original equations to calculate y. This explains the method.

Solving the equation​ √(x - 3)³ - 64 = 0 for the variable x gives x = 19

From the question, we have the following parameters that can be used in our computation:

√(x - 3)³ - 64

Express as an equation

So, we have

√(x - 3)³ - 64 = 0

Add 64 to both sides of the equation

√(x - 3)³ = 64

Take the cube roots of both sides

So, we have

√(x - 3) = 4

Square both sides of the equation

This gives

x - 3 = 16

Add 3 to the equation

Answer 7/12

Step-by-step explanation:

Answer:

Step-by-step explanation:

The radius is the length from the center dot to the circle.

They gave you the radius

r=6 1/4 in

In the given diagram, using one of the circle theorems, the value of x is 68°

From the question, we are to calculate the value of x in the given diagram.

The diagram shows a circle with O. The angle subtended at the center is 136°. We are to determine the value of the unknown angle x.

From one of circle theorems, we have that

The angle subtended by arc at the center of a circle is twice the angle at the circumference.

Therefore,

We can write that

136° = 2x

Solve for x in the above equation

136° = 2x

Divide both sides of the equation by 2

136° / 2 = 2x / 2

68° = x

Hence,

x = 68°

The multiples of 8 comprise a set of {8, 16, 24, 32, 40, ...}, while the multiples of 4 correspond to {4, 8, 12, 16, 20, ...} and  those of 2 are documented as {2, 4, 6, 8, 10, …}. The intersection of these two sets, B and C (B ∩ C = {4, 8, 12, 16, 20, ...}) remains unchanged.

It should be noted that to obtain the number of integers found in the multples of 8 that aren’t multiples either of 4 or 2, the intersection needs to be excluded from set A.

The final velocity of the sled is 4.317 m/s.

Before the snow,

Total mass of sled = 35 + 4.2 = 39.2 kg

Initial velocity of the sled = 5 m/s

Momentum = Mass × Velocity

                   = 39.2 × 5

                   = 196 kg m/s

After the snow,

Total mass = 35 + 4.2 + 6.2 = 45.4 kg

Let v be the final velocity.

By the law of conservation of momentum,

Momentum before snow = momentum after snow

196 = 45.4 v

v = 4.317 m/s

The probability that more than 8 and less than 12 customers pay in cash is 0.376 or 37.6%.

The probability that more than 8 and less than 12 customers pay in cash is calculated using the binomial probability formula:

where:

n is the number of trials = 15

x = customers who pay in cash

p = paying in cash, which is 0.4 according to the problem

The probability that more than 8 and less than 12 customers pay in cash. is the sum of the probabilities of 9, 10, and 11 customers paying in cash.

Using the binomial probability formula:

P(9) = 15C₉ * 0.4⁹ * 0.6⁶

P(9) = 0.212

P(10) = 15C₁₀ * 0.4¹⁰ * 0.6⁵

P(10) = 0.121

P(11) = 15C₁₁* 0.4¹¹ * 0.6⁴

P(11)= 0.043

The area under the curve (since the function of the parabolic expression is y = x - x²) is 1/6 square units.

A parabolic function has an expression represented as f(x) = ax² + bx + c, which allows solving for x using either the factorization method or applying the quadratic formula. By zeroing out this expression, it becomes possible to determine its roots as with any quadratic equation.

In the case of the above function:

To find the area under the curve, above the x-axis, we need to integrate the parabolic expression from 0-1

that is:

∫[0,1](x-x²)dx

This is evaluated using the power rule

∫[0,1](x-x²)dx = [1/2x² - 1/3x³) fro x= 0 to x = 1

inserting the limits of the integration, we have:
[1/2 (1) ² - 1/3 ( 1) ³] - [1/2 (0)² - 1/3 (0) ³]

Simplified, and we have :

Area  = 1/2 - 1/3

Pythagoras theorem states that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse.

If a and b are the legs of the triangle and c is the hypotenuse, then,

c² = a²+b²

Triangle EFG is a right angled triangle so also triangle DEG

x² = 625 + 400

x² = 1025

x = √1025

x = 32.02

Answer: 95 ft²

Step-by-step explanation:

      To solve for the surface area, we will find the area of all the sides and then add them together. We see that we have a square as the base and 4 congruent triangles.

For the square:

      A = LW

      A = (5 ft)(5 ft)

      A = 25 ft²

For one triangle:

      A = [tex]\frac{BH}{2}[/tex]

      A = [tex]\frac{(5\;ft)(7\;ft)}{2}[/tex]

      A = 17.5 ft²

For all four triangles:

      A = 17.5 ft² * 4 = 70 ft²

Total surface area by adding the triangles and square together:

       70 ft² + 25 ft² = 95 ft²
