The scale factor of dilation can be found by using the formula\((x_0=\frac{kx_1-x_2}{k-1}, y_0=\frac{ky_1-y_2}{k-1})\).

What is dilation?

A dilation is a transformation that creates an image that has the same shape as the original but is larger.

• An enlargement is a dilation that produces a larger image.

• A reduction is a dilation that produces a smaller image.

• A dilation expands or contracts the original figure.

A dilation is a stretch or a shrink in the size and location of a figure or point.

The scale factor in a dilation is the amount by which the figure is stretched or shrunk.

The center of dilation is a reference point used to appropriately scale the dilation of a figure. Given a point on the pre-image, \((x_1, y_1)\)and a corresponding point on the dilated image \((x_2, y_2)\)and the scale factor,

k, the location of the center of dilation, \((x_0,y_0)\) is

\((x_0=\frac{kx_1-x_2}{k-1}, y_0=\frac{ky_1-y_2}{k-1})\)

Hence, the scale factor of dilation can be found by using the formula\((x_0=\frac{kx_1-x_2}{k-1}, y_0=\frac{ky_1-y_2}{k-1})\).

The height of the Sears Tower's building is approximately 725 feet.

Let's denote the height of the building as h, and the height of the antenna as a. According to the information given, the total height of the tower (t) is the sum of the heights of the building and the antenna, so we have t = h + a.

We are also given that the difference in heights between the building and the antenna is 279 feet, meaning a = h + 279.

Substituting this value of a into the equation for t, we have t = h + (h + 279). Simplifying, we get t = 2h + 279.

Since the total height of the tower, t, is given as 1729 feet, we can now solve the equation 1729 = 2h + 279 for h.

Rearranging the equation, we have 2h = 1729 - 279, which simplifies to 2h = 1450. Dividing both sides by 2, we find h = 1450/2 = 725.

Therefore, the height of the Sears Tower's building is approximately 725 feet.

True. The 3px, 3py, and 3pz orbitals are similar in shape but differ in their orientation or direction.

The p orbitals are one type of orbital that corresponds to the angular momentum number l = 1. These p orbitals are designated as 3px, 3py, and 3pz to indicate their orientations along the x, y, and z axes, respectively.

The p orbitals have a  shape with a node at the nucleus. They consist of two lobes of electron density, one on either side of the nucleus, separated by a region of zero electron density. The lobes are oriented along the designated axes. The 3px orbital points along the x-axis, the 3py orbital points along the y-axis, and the 3pz orbital points along the z-axis. Although they have different orientations, their shapes and sizes are the same.

So, while the 3px, 3py, and 3pz orbitals differ in their orientation in space, they share the same overall shape and size.

The resultant velocity and acceleration of the skier at t=4.00 sec on the ski jump path are 12.8 m/s and 45.9 m/s², respectively.

To find the resultant velocity, first find the velocity vector components using the parametric equations:

vx = 7.00t, vy = 0.48t³ - 6.00t²/√(t⁴+1)

At t=4.00 s, vx = 28.0 m/s and vy = 10.50 m/s. The resultant velocity is the magnitude of the velocity vector, given by:

|v| = √(vx² + vy²) = 12.8 m/s

To find the acceleration vector components, differentiate the velocity vector components with respect to time:

ax = 7.00 m/s², ay = 1.44t² - 12.00t/√(t⁴+1) - 6.00t³(t⁴+1)^(-3/2)

At t=4.00 s, ax = 7.00 m/s² and ay = 45.9 m/s². The acceleration vector magnitude is:

|a| = √(ax² + ay²) = 46.1 m/s².

The given statement "For any integers a and b, if ab is even, then a is even or b is even." is true. This is because if the product of two integers is even, at least one of them must be even because the product of two odd numbers is always odd. Therefore, either a or b must be even.

Assume that a and b are integers such that a is odd and b is odd. We want to show that if ab is even, then our assumption is false.

If a is odd, then we can write a as 2k+1 for some integer k. Similarly, if b is odd, we can write b as 2m+1 for some integer m.

Then, ab can be written as:

ab = (2k+1)(2m+1) = 4km + 2k + 2m + 1 = 2(2km + k + m) + 1

Since 2km + k + m is an integer, we can see that ab is odd, which contradicts our assumption that ab is even.

Therefore, by contrapositive, we can conclude that for any integers a and b, if ab is even, then a is even or b is even.

Answer:

I’m pretty sure it’s A but if not then D

Step-by-step explanation:

In question C1, we are asked to prove that the span of the standard basis B = {e₁, e₂, ..., eₙ} for Rⁿ is equal to Rⁿ, and also that B is linearly independent.

To prove that the span of B is equal to Rⁿ, we need to show that every vector in Rⁿ can be expressed as a linear combination of the vectors in B. Since the vectors in B are the standard basis vectors, they have a value of 1 in only one component and 0 in all other components. Any vector in Rⁿ can be written as a linear combination of these standard basis vectors by assigning appropriate coefficients. Therefore, the span of B includes all possible linear combinations, covering all vectors in Rⁿ.

To prove that B is linearly independent, we need to show that the only solution to the equation a₁e₁ + a₂e₂ + ... + aₙeₙ = 0 (where a₁, a₂, ..., aₙ are scalars) is when a₁ = a₂ = ... = aₙ = 0. Since the vectors in B are distinct and have a value of 1 in only one component, the only way the equation can hold true is when all the coefficients are zero. Thus, B is linearly independent.

Overall, the proof establishes that the span of the standard basis B is equal to Rⁿ, indicating that B can represent any vector in Rⁿ, and also verifies that B is linearly independent, implying that the vectors in B are not redundant or dependent on each other.

If a business had sales of $4,000,000, and a margin of safety of 25%, the break-even point was is c. $1,000,000.

The margin of safety is the difference between the actual or expected sales and the break-even point. In this case, if the margin of safety is 25%, it means that the business is generating sales that are 25% higher than the break-even point.

To calculate the break-even point, we can use the following formula:

Break-even point = Fixed costs / Contribution margin ratio

The contribution margin ratio is the difference between the sales price and variable costs, divided by the sales price. We don't have enough information to calculate it directly, but we can use the margin of safety to estimate it.

If the margin of safety is 25%, it means that the contribution margin ratio is 25% of the sales price. So, the variable costs must be 75% of the sales price, and the contribution margin ratio is 25%/100% = 0.25.

We know that the sales are $4,000,000, but we don't know the fixed costs. However, we can use the break-even formula to solve for it:

$1,000,000 = Fixed costs / 0.25

Fixed costs = $250,000

Therefore, the break-even point is $250,000 / 0.25 = $1,000,000.

Based on the given information, the break-even point for the business with sales of $4,000,000 and a margin of safety of 25% is $1,000,000.

By using distributive property 15(3 + 8) 15 11 = 165 both approaches yield the same conclusion.

Distrubutive Property Formula : a(b+c)=a b+a c

The distributive property is also known as the distributive law of multiplication over addition and subtraction. By its very name, the procedure implies that something will be divided or distributed.  According to the distributive property, an expression of the form A (B + C) can be resolved as A (B + C) = AB + AC. Subtraction also belongs to the scope of this distributive law, which is expressed as A (B - C) = AB - AC. The distribution of operand A among the other two operands is seen from this.

A (B + C) = AB + AC represents the distributive property of multiplication over addition.

15(3+8) = (15.3) + (15.8)

15.11 = 45 + 120

165 = 165

Using the law of BODMAS, we can now attempt to solve the expression. The solution is as follows. We will first add the figures in brackets, and then we will multiply this total by the figure outside of the brackets.

Hence, using distributive property, it follows that 15(3 + 8) x 15 = 165. As a result, both approaches yield the same conclusion.

False. The normal account balance of Purchases Returns and Allowances is a credit, not a debit.

Purchases Returns and Allowances is a contra-expense account, which means it is used to reduce the balance of the Purchases account. When merchandise is returned to the supplier or an allowance is granted by the supplier, the Purchases Returns and Allowances account is credited, which reduces the amount of the original purchase.

Since the Purchases Returns and Allowances account is a contra-expense account, it has an opposite balance to that of the regular expense account it is associated with, which is Purchases. Purchases has a normal debit balance, so Purchases Returns and Allowances has a normal credit balance.

Answer:

\(\sqrt{117}\) or \(3\sqrt{13}\)

Step-by-step explanation:

The formula for finding the any side of the triangle is

\(a^{2}+b^{2} =c^{2}\)

We know that a=2 and c=11, so we can go ahead and plug those into the formula.

\(2^{2}+b^{2} =11^{2}\)

\(4+b^{2} =121\)

To find side b, we have to make it alone on one side. Subtract 4 on both side.

\(b^{2} =117\)

Now square root both sides, and that leaves us with:

\(b=\sqrt{117}\) or \(3\sqrt{13}\)
