a. A function to model taking the 10% discount will be 0.9x.

b. A function to model taking the 25% discount first will be 0.75x.

c. If I was an employee, I'll prefer the 25% discount.

From the information given, the store is offering a 10% discount on all items and in addition, employees get a 25% discount.

Let the price of the goods be given as x.

A function to model taking the 10% discount will be:

= x - (10% × x)

= x - 0.1x

= 0.9x

A function to model taking the 25% discount first will be:

x - (25% × x)

= x - 0.25x

= 0.75x

The square form of r^2 + 4r + 4. is (r + 2) (r + 2)= 0 and the value of co-interior angle x is 140 degrees.

Co-interior angles, also known as consecutive interior angles, are those between two lines that are split by a third line (transversal), and are located on the same side of the transversal.

Given that, r^2 + 4r + 4.

Expand the terms as follows:

r^2 + 4r + 4.

r^2 + 2r + 2r + 4 = 0

r(r + 2) + 2(r + 2) = 0

(r + 2) (r + 2)= 0

The sum of co-interior angles is 180 degrees:

x + 40 = 180

x = 140 degrees.

Hence, the square form of r^2 + 4r + 4. is (r + 2) (r + 2)= 0 and the value of co-interior angle x is 140 degrees.

The largest possible area for a rectangle with a base on the x-axis and both upper vertices on the curve y=5−x² , is equals to the 20√15/ 9 .

In optimizing the objective function f(x), solve for the critical points by putting the first derivative f′(x), equals to zero. Then the objective function is evaluated at the critical points to determine the it's minimum or maximum. We have, a rectangle with base as x-aixs and both upper vertices on the curve y = 5 − x², which is a parabola equation. Thus width of the rectangle is based from the equation of the parabola y= 5 - x² --(1)

Area of rectangle is expressed as A = xy , where x -->length of it and y-->width or vertices of curve. The length of the rectangle with base x- axis is equal to 2x. Therefore, the area is A = w× l

= 2x( 5 - x² )

A = 10x - 2x³ --(2)

If area is maximum, then dA/dx = 0

Differentiating the equation (2) with respect to x

dA/dx = 10 - 6x²

so, 10 - 6x² = 0

=> 6x² = 10

=> x² = 10/6

=> x² = 5/3

=> x = ±√5/3

but x represents the length so, it's value always be positive. Thus, x = √5/3. The area is equal to A = 10x - 2x³

= 10(√5/3) - 2(√5/3)³

=> A = 10√5/3 - 10/3(√5/3)

=> A = √5/3( 10 - 10/3) = 20√5/3√3

=> A = 20√15/ 9 ( using rationalzation )

Hence, the required area is 20√15/ 9 .

Based on the definition of congruent triangles, the measures are:

4. m<R = 75°

5. XY = 6

6. m<X = 55°

7. m<S = 50°

Congruent triangles are two triangles that have the same size and shape. This means that all corresponding sides and angles of the two triangles are equal in measure.

Since triangles QRS are congruent to each other, therefore, their corresponding parts will be equal. Thus:

Pablo's error was that he added the equations.

A possible first step is to subtract the equations.

The solution of the system is x = -2 and y = 8.

One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.

Given:

We have s system of equations,

3x + 4y = 26   {equation 1}

2x + 4y = 28   {equation 2}

Pablo is solving the system of equations shown and says that the first step is to add the equations together to eliminate the y variables.

To eliminate the y-variable:

Subtract equation 2 to equation 1.

3x - 2x = 26 - 28

x = -2

Then y = 8.

Therefore, the solution of the system is x = -2 and y = 8.

Answer:

Try continuity formula you get your answer

The solution to the initial value problem using the method of Laplace transforms is y(t) = (1/3)e^3t - (4/3)e^-2t + 4e^2t

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

y" - 3y' - lOy = 0, y(0) = 1, y'(0) = 12

Let L{y(t)} = Y(s),

Take the Laplace transform of both sides, we have:

s^2Y(s) - sy(0) - y'(0) - 3sY(s) + 3y(0) + 10Y(s) = 0

Using initial conditions y(0) = 1 and y'(0) = 12, we get:

s^2Y(s) - s - 12 - 3sY(s) + 3 + 10Y(s) = 0

Solving for Y(s), we have:

Y(s) = (s + 12)/(s^2 + 3s + 10)

Taking inverse Laplace transform of Y(s), we have:

y(t) = L^-1{Y(s)}

y(t) = (1/3)e^3t - (4/3)e^-2t + 4e^2t

Hence, the solution is y(t) = (1/3)e^3t - (4/3)e^-2t + 4e^2t

The interquartile range of the following data set 4, 6, 10, 13, 18, 28, 34, 46, 50, 58 is 36.

What is interquartile range?

The difference between the third and the first quartile is defined by the interquartile range. The partitioned values known as quartiles divide the entire series into four equally sized segments. There are so three quartiles. The first quartile, also known as the lower quartile, is marked by Q1, the second quartile by Q2, and the third quartile, sometimes known as the upper quartile, is denoted by Q3. The lower quartile less the upper quartile equals the interquartile range.

The data set given is - 4, 6, 10, 13, 18, 28, 34, 46, 50, 58

Divide the data set into two parts -

D1 = 4, 6, 10, 13, 18

D2 = 28, 34, 46, 50, 58

The two middle value for data set is 18 and 28.

The median of D1 and D2 is -

Median = (18 + 28) / 2

Median = 46 / 2

Median = 23

The middle value for D1 is Q1 = 10 and for D2 is Q3 = 46.

Answer:

10.16 lb

Step-by-step explanation:

This is a classic example of a problem that can be solved using dimensional analysis. To find the weight of a single shock absorber or brake pad set, you need to divide the total weight by the number of items in the box.

Weight of a single shock absorber = Total weight of shock absorbers / Number of shock absorbers in the box

= 101.6 lb / 8

= 12.7 lb

Weight of a single brake pad set = Total weight of brake pad sets / Number of brake pad sets in the box

= 101.6 lb / 10

= 10.16 lb

Therefore, a single shock absorber weighs 12.7 lb and a single brake pad set weighs 10.16 lb.

to get the equation of any straight line, we simply need two points off of it, let's use those two in the picture below.

The rank of the points having a maximum moment of inertia is c > a > b.

The figure of 25 % snipped off square-shaped uniform metal plate.

We can rank the points according to the moment of inertia using the relation between the moment of inertia and the radius of gyration of the elements.

The formulae are as follows:

I = mh²

Where h = Radius of gyration, m is mass, and I is the moment of inertia.

Here,

I = mh²

So, the final moment of inertia will be maximum for the axis, which consists of elements having more h (which are more distant from the axis).

From this, it can be concluded that the moment of inertia about an axis through point c is maximum, followed by (a) and then (b).

Rank is c > a > b

Therefore, the points can be ranked according to the moment of inertia about the axis passing through it using its relationship with the radius of gyration.
