The new equation after moving 3 units to the right and 3 units up is

[tex]f(x) = (x - 4)^{2} 2 + 1.[/tex]

We need to change the equation to move the function [tex]f(x) = (x - 1)^{2} 2 - 2[/tex] three units to the right and three units up:

To shift the function three units to the right, replace x with (x - 3), which adjusts the graph three units to the right. [tex]f(x) = ((x - 3) - 1)^{2} 2 - 2[/tex], which simplifies to [tex]f(x) = (x - 4)^{2} 2- 2.[/tex]

To move the function three units up, multiply the equation by three.[tex]f(x) = (x - 4)^{2} 2 + 1[/tex] is the final equation.

Answer:

a. To find the scale factor of JKLM to EFGH, we can compare the corresponding sides:

JK/JH = KL/KG = LM/LF = x/x = 1

Therefore, the scale factor is 1.

b. Since JKLM~EFGH, the corresponding sides are proportional. We can set up the following ratios:

JK/EF = KL/FG = LM/FH = 1/1

JK/x = KL/20

LM/30 = 1/2

Solving for JK, KL, and LM:

JK = EF = x

KL = 20(1/2) = 10

LM = 30(1/2) = 15

c. To find the perimeter of JKLM, we add the lengths of its sides:

Perimeter of JKLM = JK + KL + LM + MJ

Perimeter of JKLM = x + 10 + 15 + x

Perimeter of JKLM = 2x + 25

To find the perimeter of EFGH, we can use the fact that corresponding sides are proportional:

FG = KL = 10

FH = LM = 15

EG = JK = x

EH = EF = x√2

Perimeter of EFGH = EF + FG + GH + EH

Perimeter of EFGH = x + 10 + 2z + x√2

We are not given a value for z, so we cannot calculate the perimeter of EFGH.

Answer:

Step-by-step explanation:

The expected value of each warranty sold can be calculated using the following formula:

Expected Value = (Probability of Failure without warranty x Replacement Cost without warranty) + (Probability of Failure with warranty x Replacement Cost with warranty) - Cost of Warranty

Probability of Failure without warranty = 0.8% or 0.008 (given)

Replacement Cost without warranty = $200 (given)

Probability of Failure with warranty = 0% (since the product is covered under warranty)

Replacement Cost with warranty = $0 (since the cost of replacement is covered under warranty)

Cost of Warranty = $30 (given)

Expected Value = (0.008 x $200) + (0 x $0) - $30

Expected Value = $1.60 - $30

Expected Value = -$28.40

The company's expected value of each warranty sold is -$28.40, which means that on average, the company can expect to lose $28.40 for every warranty sold. This is because the cost of the warranty ($30) is greater than the expected cost of replacement without the warranty ($1.60). Therefore, it is not beneficial for the company to offer the extended warranty.

The side has a length of 15 units.

Let us denote the length of the missing side by x. According to the Pythagorean theorem, the sum of the squares of the lengths of the two legs of a right triangle is equal to the square of the length of the hypotenuse. In mathematical terms, this can be written as:

side² + side² = hypotenuse²

Substituting the given values, we get:

x² + 8² = 17²

Simplifying this equation, we get:

x² + 64 = 289

Subtracting 64 from both sides, we get:

x² = 225

Taking the square root of both sides, we get:

x = 15

Therefore, the missing side has a length of 15 units.

Yes, your answer is correct.

The coordinates of the division point T are indeed (0, 5/3, -4/3).

We have,

To find the coordinates of the division point T, we use the formula:

T = A + r(B - A)

where r is the ratio in which AB is divided.

In this case, the ratio is 1:2, so r = 1/3 (since 1 + 2 = 3).

Substituting the given values.

T = (3, 2, -1) + (1/3)(-9, -1, -1)

T = (3, 2, -1) + (-3, -1/3, -1/3)

Answer:

Since Giovanna deposited half of the money into each account, she deposited $1600 / 2 = $800 into each account.

Let's assume that First Oak offers an annual interest rate of r1, and West United offers an annual interest rate of r2. The amount of interest earned on each account after 5 years would be:

Interest earned on First Oak = $800 * r1 * 5

Interest earned on West United = $800 * r2 * 5

The total interest earned from both accounts would be the sum of these two amounts:

Total interest earned = $800 * r1 * 5 + $800 * r2 * 5

Total interest earned = $4000 * (r1 + r2)

We are not given the interest rates, so we cannot calculate the exact amount of interest earned. However, we can use the given information to make some observations.

Since we are looking for the total interest earned from both accounts, we can simplify the problem by assuming that the interest rates for both accounts are the same. In this case, we have:

Total interest earned = $4000 * 5 * r

Total interest earned = $20000 * r

To find the interest earned, we need to know the value of r. If, for example, the annual interest rate is 4%, then:

r = 0.04

Total interest earned = $20000 * 0.04

Total interest earned = $800

Therefore, if the interest rates for both accounts are the same and equal to 4%, Giovanna would have earned $800 in interest from both accounts at the end of 5 years. However, if the interest rates are different, the total interest earned would be different as well.

Without knowing the interest rates for the two accounts Giovanna deposited her money in, it's not possible to calculate the total interest she'd earn in 5 years. Normally, you would need to use the Simple Interest formula for each account and then add the two results together.

This is a Mathematics question about simple interest, which can be solved using the formula: Interest = Principal × Rate × Time. Given that Giovanna divided her money equally into two accounts at First Oak and West United, she put $800 into each account. However, without information about the annual interest rates for both accounts, we can't calculate the amount of interest Giovanna would earn after 5 years. Once the specific interest rates for the two accounts are provided, one could use the Simple Interest formula for each account and then add the interest from both to get the total.

The figure that Kyle plans to estimate the area of contains 40 full squares and 8 partial squares. Based on this information, we can assume that the figure is composed of a grid or a series of squares that are either full or partially shaded. Kyle plans to use the strategy of identifying the full and partial squares that make up the figure to estimate its area.

If the figure is a perfect square or rectangle, Kyle can use the formula A = l x w to find its exact area. However, since the figure is not described as a specific shape, Kyle will need to use estimation to find its area. By identifying the full and partial squares, he can estimate the total number of square units that the figure covers. Kyle can then multiply this estimate by the size of each square unit to find an approximate area.

The area of the flower bed is 180 square feet.

Area refers to the amount of space occupied by a two-dimensional shape or surface. It is measured in square units, such as square meters, square inches, or square centimeters. The area of a shape can be calculated by multiplying the length and width of the shape (in the case of a rectangle or square), or by using more complex formulas for other shapes, such as triangles or circles.

To convert yards to feet, we multiply by 3 since 1 yard = 3 feet.

The length of the rectangle in feet is 5 yards × 3 feet/yard = 15 feet.

The width of the rectangle in feet is 4 yards × 3 feet/yard = 12 feet.

The area of the rectangle in square feet is length × width = 15 feet × 12 feet = 180 square feet.
