The graph of function d is a reflection across the y-axis of the graph of function t.

In Geometry, there are different types of transformation and these include the following:

A reflection can be defined as a type of transformation which moves every point of the object by producing a flipped but mirror image of the geometric figure.

In Geometry, a reflection across the y-axis (y = x) of a graph is given by this transformation rule (x, y) → (-x, y). This ultimately implies that, function t(x) = -4x + 72 would be transformed to function d:

d(x) = -(-4x) + 72.

d(x) = 4x + 72.

Chicago Cubs score between -2.86 and 10.58 runs every game, or at least 75% of their total.

The Chebyshev's Theorem calculates the minimal percentage of observations that are within a certain range of standard deviations from the mean. A wide variety of probability distributions can be used with this theorem. Another name for Chebyshev's Theorem is Chebyshev's Inequality.

Given Mean (X) = 3.86, Standard deviation (SD) = 3.36

According to Chebyshev’s Theorem,

1-1/k^2  proportion of values lies between Mean ± (k × SD )

Given k = 2.

k = x - mean /SD

1-1/k^2 =1-1/2^2

⇒1-1/4=1-0.25

⇒0.75

Therefore Proportion Value = 75%

If k= 2

75% Chebyshev’s intervals are

Lower Limit = Mean - (k × SD )

⇒3.86 - (3.36×2)

⇒3.86 - 6.72 = - 2.86

Upper Limit = Mean + (k × SD )

⇒3.86 + (3.36 × 2)

⇒3.86+6.72 = 10.58

Hence the Chicago Cubs score between -2.86 and 10.58 runs every game, or at least 75% of their total.

Suppose that the relationship between the tax rate t on imported shoes and the total sales S (in millions of dollars) is given by the function below. The tax rate t that maximizes revenue for the government is 66.992%.

Revenue can be defined as the amount or the income a person or an organization generated from the sales of goods and services.

Given function :

Total sale  = S(t) = 7−6∛t

Hence,

Expression for Revenue rate = r(t) = tS(t)

Now let substitute and solve  expression

r(t) = t (7−6∛t)

= 7t−6(t)^4/3

Differentiate the expression

d[r(t)] dt = r′(t)

r′(t) = 7− (4/ 3) 6(t)^1/3

=7−8(t) ^1/3 ........ expression (1)

Maximum revenue

r′(t) = 0

Substitute and solve expression (1)

0 =7−8(t)^1/3

(t) = (7/8)^3

= 0.66992 × 100

= 66.992%

Therefore we can conclude that the tax rate t that maximizes revenue is 66.992%.

After all the transaction, money left in the bank account is $15.8872.

Given that, you open your bank account on April 16 with a tax refund check of $145.00. You pay Sell Phone $65.34 on April 18.

A tax refund is a reimbursement to a taxpayer for any excess amount paid to the federal government or a state government.

On  April 16th balance in the account = $145.00 cost of phone = $65.34 on April 18.

Balance on April 18 = 145.00-65.34

= $79.66

Deposited check $9.76 on 23rd April for 35 hours

Balance on 23rd April = 79.66+9.76

=$89.42

Since, the check deposited only for 35 hours, again balance on 24th April will be $79.66

On 24th April you brought clothes from BargainsRUs for

The after tax cost of debt for the bond is 2.73%

Given,

The face value of the bond, FV = $1000

Present value of the bond, PV = $995.28

Maturity period = 19 years

Coupon rate = 3.5%

Total tax rate = 22%

We have to find the after tax cost of debt for the bond.

The bond pays interest semiannually ;

so coupon rate = 3.5/2 = 1.75

Coupon payment , pmt= 0.0175 x 1000 = $17.5

Maturity, nper = 19 years x 2 = 38

Compute yield rate using spreadsheet = Rate(nper,pmt,-PV, FV)

Then,

= RATE(38, 17.5, -995.28, 1000)

Rate or yield is computed as 3.5%

The present value is negative as it is a cash outflow.

The cost of debt is 3.5%

log y = 1/2 [ log x(x+4) - log (5x +1)(3x + 7) ]

log y = 1/2 [ log x(x+4) - log(5x + 1) - log (3x + 7) ]

Derivation on both sides.

[ d(logx)/dx = 1/x ]

d (log y) / dx = d [ {1/2 log x(x+4) - log(5x + 1) - log (3x + 7)} ] / dx

1/y y' = 1/2[ 1/x(x+4) - 1/(5x + 1) - 1/(3x + 7) ]

Combining the three different transformations—rotations, reflections, and translations—will result in congruent shapes. Actually, any pair of congruent shapes can be matched to one another using a combination of one or more of these three transformations.

There are four possible transformations of a point, line, or geometric figure, each of which changes the object's shape and/or location. Pre-Image denotes the shape of the object before transformation, while Image denotes the final position and shape of the object.

We now know that during rigid transformations, the size and shape of the figures are maintained (reflections, translations, and rotations). The pre-image and the image are always in agreement.

Matt has the following transformational abilities:

Reflection (Flip)

A reflection keeps its original shape because the comparable points from the pre-image to the image stay at the same distance from the line of reflection.

Rotations as a Congruence Transformation

Rotations as a Congruence Transformation

A figure twists when it rotates. The figurine looks to have fallen over, although being the same size and shape. A great illustration of a rotation in the actual world is a clock. The connecting arms of a clock rotate around its axis every hour or every day. A rotation is defined by its degree; common rotations include 90 degrees, 180 degrees, and 270 degrees. The figure completes a full 360-degree rotation before returning to its starting point. A rotation must include indicate the clockwise or counterclockwise direction. This information can be used to calculate the degree, quantity, and direction of a revolution.

Translational congruence transformation

We refer to a movement as a translation when an object or shape is moved from one place to another without changing its size, shape, or orientation. Every point on an item or shape is moved by the same amount and in the same direction during a translation, sometimes referred to as a slide.

length:15 cm

width: 14 cm

Explanation

Step 1

Let

w represents the width of the rectangle

l represents the length of the rectangle

a)The width of a rectangle is 4 less than the length,hence

write this in math terms, replace

b)the area of the rectangle is 165 square cm

the area of a rectangle is given by

Step 2

now, solve the equations

a) replace the w from equation (1) into equation(2)

b) now, we have a quadratic equation in the form

hence, we can use the quadratic formula to solve

let

a=1

b=-4

c=-165

replace

therefore

as we are searchinf for a distance, the only valid answer is 15

so, the answer is length= 15 cm

c) finally, replace the l value into equation (1) to find the width

therefore, the width is 11 centimeters

Explanation:

If we have a function g(x) = -f(x), then g(x) will be f(x) reflected across the x-axis.

If g(x) = f(x) - c, g(x) will be f(x) shifted c units down

If g(x) = f(x + c), g(x) will be f(x) shifted c units to the left.

In this case, the initial function is f(x) = |x| and g(x) = -|x + 3| - 2, then

g(x) = -f(x + 3) - 2

Therefore, g(x) will be the initial function reflected across the x-axis, shifted 3 units to the left and 2 units down.
