The correct answer is 7XS when RR' = 14, then RZ = 7 when the parallelogram PQRS is reflected across the line of reflection.

Given that,

If RR' = 14, then RZ = 7 when the parallelogram PQRS is reflected across the line of reflection.

SX = 5 if Y = 5.

In Euclidean geometry, a parallelogram is a straightforward (non-self-intersecting) quadrilateral with two sets of parallel sides.

A parallelogram has equal-length opposing angles and facing or opposing sides.

The Euclidean parallel postulate or one of its equivalent formulations must be used in order to demonstrate the congruence of opposite sides and angles because both requirements flow naturally from this postulate.

A quadrilateral with only one pair of parallel sides, on the other hand, is referred to in British or American English as a trapezoid or trapezium.

We get,

The parallelepiped is a three-dimensional representation of a parallelogram.

The value of Tim's house at the start of 2018 is £146410

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

Initial value = 100,000

Rate of increase = 10%

The value of the house x years after 2014 can be represented as the following exponential function

Value = Initial value * (1 + rate)ˣ

So, we have

Value = 100000 * (1 + 10%)ˣ

2018 is 4 years after 2014

This means that x = 4

So, we have

Value = 100000 * (1 + 10%)⁴

According to the volume of the box, the height of the box is (2x + 3)

Volume:

Volume is defied as the space occupied within the boundaries of an object in three-dimensional space.

Given,

In order to package products for her business class, Jessica needs to determine the size of a box in which they would fit. To meet shipping specifications, the volume of the box should be 6x² - 15x-36. The box is in the shape of a rectangular prism. The width of the box must be 3, and the length of the box must be x - 4.

Now, we have to find the expression or the height of the box.

From the given details, we know that,

Volume of the box = 6x² - 15x-36

Width of the box = 3

length of the box = x - 4

Let us consider the height of the box is h.

By using the volume of the box formula, we have calculated the height of the box as,

=> 6x² - 15x-36 = (3) × (x-4) × h

Here we need the value of h,

The given expression is rewritten as,

=> (6x² + 15x-36) / 3(x - 4) = h

When we factorize the numerator, then we get,

=> 3(2x + 3)(x - 4)/3(x-4) = h

The net present value formula helps us to determine the net present value of boat repair model B14 model by Cleveland Cove enterprises.

so, the net present value is 384,285.714.

Net present value: The net present value is applied to a series of cash flows occurring at different times. The present value of a cash flow always depends on the interval of time between now and the cash flow.

NPV = Rt /(1+i)^t

where , Rt --> net cash flow at time t

i --> discount rate

t --> time of cash flow

We have given that , A company has narrowed their choices down to two: the B14 Model and the F54 Model.

F54 Model :

Residual value , = 18,000

Annual net cash inflow = 30,000

investment = 230,000

time , t = 10

rate of return,r = 12%

B14 Model :

Residual value , = 10,000

Annual net cash inflow = 80,000

investment = 330,000

time , t = 10

rate of return,r = 8%

we have to calculate the net present value for model B14.

so, Net present Value = present value of annually cash - investment

present value of annually cash

= 80000/1.12 = 71,428.571

Net present value =71,428.571 ×10 - 330000

YES, the absolute value of an integral is always less than the integral of the absolute value for Lebesgue integrals.

An integral is like a sum, but fancier. So look at a sum 1+(-5)+2+(-3)=-5. Take the absolute value, |1+(-5)+2+(-3)|=5. But, if you take the absolute value of the individual terms and then add them, you get |1|+|-5|+|2|+|-3|=1+5+2+3=11. 11>5

The reason is that when you add them all up and then take the absolute value, the positive and negative terms of the sum get to cancel each other out and make the absolute value of the sum greater overall. When you take the absolute value of individual terms, you force them all to "point in the same direction" (positive) so they are working together and the sum gets higher.
