The required equation that represents the graph is j(x) =  (-x + 4)¹/². Option D is correct.

A parabola is a cross-section cut out of the cone and represented by an equation x = y².

here,
The given graph is of the left parabola,
-x = y²
When we translate the above expression 4 units right we get the graph,
So
-x + 4 = y²

put y = j(x)

-x + 4 = j(x)²
j(x) = [-x + 4]¹/²

Thus, the required equation that represents the graph is j(x) =  (-x + 4)¹/². Option D is correct.

If a/2-b/3 = 1, then we can write:

2(a/2-b/3) = 2

Combining like terms, we have:

a - b/3 = 1

Multiply both sides by 3 to get:

3a - b = 3

Now, we can add b to both sides of the equation:

3a = b + 3

Finally, we can divide both sides by 3 to get:

a = (b + 3)/3

Now we can substitute this value of a into the original equation

2a + 3b = 2(b + 3)/3 + 3b = 2b/3 + 6/3 + 3b = 2b + 2 + 3b = 5b + 2

So 2a+3b = 5b + 2 in terms of b

The true diameter of the Venus given the angular diameter of 0.018 is about 39.7 million km.

An angular distance used to describe how big a sphere or circle seems from a certain point of view is known as the angular diameter, angular size, apparent diameter, or apparent size. It is known as the visual angle in the vision sciences and as the angular aperture in optics (of a lens). The angular diameter may also be thought of as the angle that a camera or eye must spin around in order to view from one side of an apparent circle to the other.

Given that the angular diameter of Venus is 0.018 degrees.

The true diameter of the planet is calculate using the following formula:

diameter = distance (angular diameter / 57.3)

Substitute the value of distance = 38.5 million and angular diameter = 0.018 degrees.

diameter = 38.5 * 10^6 (0.018 / 57. 3)

diameter = 39. 7 million

The magnitude and direction of the force C are 93.853 pounds-force and  281.237°, respectively.

In this problem we find the case of a system at equilibrium and formed by 3 vectors, of which we must determine the magnitude and direction of a force must be determined. Vectors are described by two features: (i) Magnitude, (ii) Direction.

The magnitude is obtained by Pythagorean theorem:

F = √(x² + y²)

The direction is determined by inverse trigonometric functions:

θ = tan⁻¹ (y / x)

Besides, the system can be described physically by Newton's laws and mathematically by vector sum:

F₁(x, y) + F₂(x, y) + F₃(x, y) = (0, 0)

First, determine the vector associated to force C:

F₃(x, y) = - F₁(x, y) - F₂(x, y)

F₃(x, y) = - (- 92 · cos 45°, 92 · sin 45°) - (54 · cos 30°, 54 · sin 30°)

F₃(x, y) = - (- 46√2, 46√2) - (27√3, 27)

F₃(x, y) = (46√2, - 46√2) - (27√3, 27)

F₃(x, y) = (46√2 - 27√3, - 46√2 - 27)

Second, calculate the magnitude of force C:

F₃ = √[(46√2 - 27√3)² + (- 46√2 - 27)²]

F₃ ≈ 93.853

Third, determine the direction of force C:

θ = tan⁻¹ [(- 46√2 - 27) / (46√2 - 27√3)]

θ ≈ 281.237°

Answer:

  F₃ = 94 lb at 78.8° below the +x axis

Step-by-step explanation:

You want the magnitude of force F₃ that makes the sum of forces be zero.

As you have already noted, the sum of forces is zero when the system is at equilibrium.

  F₁ +F₂ +F₃ = 0

  F₃ = -(F₁ +F₂)

The forces F₁  and F₂ can be added by adding their horizontal and vertical components.

  F₁ = 92(cos(135°), sin(135°)) ≈ (-65.0538, 65.0538)

  F₂ = 54(cos(30°), sin(30°)) ≈ (46.7654, 27)

Then the sum of forces is ...

  F₁ +F₂ ≈ (-18.2884, 92.0538) . . . . . sum of corresponding parts

As we noted above, F₃ is the opposite of the sum, so is ...

  F₃ = (18.2884, -92.0538)

The magnitude is found using the Pythagorean theorem:

  |F₃| = √(18.2884² +(-92.0538)²) ≈ √8808.3677 ≈ 93.8529

The magnitude of F₃ is about 94 lb.

The components of F₃ tell you the force is in the 4th quadrant. The ratio of the x- and y-components is the tangent of the angle:

  θ = arctan(y/x) = arctan(-92.0538/18.2884) = arctan(-5.03345)

  θ ≈ -78.763°

In the first attachment, the sum of forces F₁ +F₂ is shown by the black arrow. The direction of F₃ will be the opposite of that arrow's direction, so will be down to the right, about 78.8° below the +x axis. The second attachment shows the magnitude and direction of F₃, where 0° is the direction of the +x axis.

__

Additional comment

For finding the magnitude of the sum of two forces, the Law of Cosines is another way to do it. To use that, you need to know the angle between the two forces. That's the angle at lower right inside the triangle shown in the first attachment. It is 75°. Then the magnitude is ...

  |F₃| = √(54² +92² -2·54·92·cos(75°)) ≈ √8808.37 ≈ 93.853 . . . . lb

This math can be simpler than working with the x- and y-components of the forces.

The angle of F₃ is another matter. Finding that requires solving the force triangle for one of the other interior angles, then adding the angles in the appropriate way.

For example, the angle at the origin can be found from the Law of Sines as ...

  α = arcsin(92/93.853·sin(75°)) ≈ 71.237°

Adding this to the angle of the red vector (30°) gives the resultant angle relative to the +x axis of 101.237°. The direction of F₃ is opposite this, so is ...

  101.237° -180° = -78.763° . . . . as above

As you can see from the attachments, a vector calculator or spreadsheet is a useful tool for finding sums of forces from their magnitude and direction.

Just to be clear, the conversion between polar and rectangular forms is ...

  (x, y) = r(cos(θ), sin(θ))

  r = √(x² +y²)

  θ = arctan(y/x) . . . . . with attention to quadrant

Spreadsheets and some calculators have an ATAN2(x, y) function that takes the signs into account when it computes the angle. When working with angles, make sure the calculator's angle mode is set to degrees or radians appropriately. (Spreadsheets usually use radians.)

Answer:

The slope-intercept form of a line is y = mx + b, where m is the slope and b is the y-intercept.

To find the equation of the line with a slope of 2/3 and passing through the point (3, -4), we can plug in the point and the slope into the equation:

y = 2/3 * x + b

-4 = 2/3 * 3 + b

-4 = 2 + b

b = -6

So the equation of the line is:

y = 2/3 x - 6

Answer: The relationship between the variables x and y in the given data points is linear.

Step-by-step explanation: A linear relationship is one in which the change in the y-value (output) is always the same for a given change in the x-value (input), regardless of the starting point. In other words, the slope of the line is constant.

In this case, the slope of the line can be calculated by finding the difference in y-values for a given difference in x-values between two points. We can pick any two points, for example:

(X: -6, Y: 12) and (X: 6, Y: 20)

The slope can be calculated by:

m = (20 - 12) / (6 - (-6)) = 8/12 = 2/3

This means that for every 1 unit increase in x, y increases by 2/3 units.

This is a linear relationship.

In contrast, in an exponential relationship, the y-value increases (or decreases) at a constantly increasing (or decreasing) rate as the x-value increases.

A linear function rule to model the distance in feet {d} the car has traveled any number of seconds {t} after passing the timing device is

Given is that a car moving at a constant speed passed a timing device at t = 0 s. After 9s, the car has traveled 828 ft.

We can write the linear function as -

y = mx

Now, we can write the slope as -

So -

d = 92t

If a baker will supply 22 jumbo cinnamon rolls to a cafe at a price of $3.46 each.   the equilibrium point is: 20 rolls and the price is $4.86.

The equilibrium point is where the supply and demand curves intersect, representing the price and quantity where the market is in balance.

Let's call the number of rolls the baker supplies x.

At the original price of $3.46 each, she supplies 22 rolls.

When offered $3.16, she will supply 2 fewer rolls, so she supplies x = 22 - 2 = 20 rolls.

We can use the demand equation to find the corresponding quantity demanded for each price:

p = D(x) = -0.25x + 6.56

D(22) = -0.25 * 22 + 6.56 = 4.56

D(20) = -0.25 * 20 + 6.56 = 4.86

The intersection of the two points (22, 4.56) and (20, 4.86) gives us the market equilibrium quantity and price.
