1. Find the measure of <6.


2. Find the measure of <4.

A polynomial that satisfies given conditions is:

P(x) = x³ - x² + 81x - 81

In this question, we need to find a polynomial that satisfies given conditions.

We have been given that -9i is a root of polynomial.

This means, the conjugate of -9i that is, 9i must be a root of polynomial p.

From given information we can say that the zeros of polynomial p(x) must be (x - 1), (x + 9i), and (x - 9i)

So, we get a polynomial p(x) = 0

(x - 1)(x + 9i)(x - 9i) = 0

(x - 1)(x² - (9i)²) = 0

(x - 1)(x² - (-81)) = 0

(x - 1)(x² + 81) = 0

x³ - x² + 81x - 81 = 0

Therefore, a polynomial that satisfies given conditions is:

P(x) = x³ - x² + 81x - 81

Answer:

Domain: (-∞, +∞)

Range: [2, +∞)

Step-by-step explanation:

Domain is the "allowable x-values/inputs"

Range is the "possible y-values/outputs when the x-values in the domain are inputted".

From the graph, notice how each end of it extends infinitely to the left and to the right. This means that the domain is infinite and there are no restrictions. Writing it in interval location would look like this:

(-∞, +∞)

Also, notice how the y-values increase from the vertex but do not go below it. That suggests that the range is "lower-bounded" to the vertex, and increases infinitely. Writing it in interval location would look like this:

[2, +∞)

Answer: Area of triangle=30 cm²

Step-by-step explanation:

Let's name the triangle ABC.

Assuming these are the 3 sides of the triangle, and naming them a,b,c.

a=5 cm

b=13 cm

c=12 cm

Semi perimeter of the triangle ABC= s = (a+b+c)/2

s=(5+13+12)/2 =30/2=15.

Area of triangle ABC= √(s * (s-a)*(s-b)*(s-c)

                                  =  √(15*(15-5)*(15-13)*(15-12)

                                  =  √15*10*2*3

                                  = √150*6

                                  =√900

                                   =30 cm²

Area of triangle ABC = 30 cm².

Answer: The size of the sugar order decreased by 40%.

Step-by-step explanation:

1,090 is 100%

654 is 60% of 1,090 (1,090 ÷ 0.6 = 654)

1,090 - 654 =  436, and 436 is 40% (0.4) of 1,090

1,090 (100%) - 436 (40%) = 654 (60%)

The percent of the decrease in the size of the sugar order is 40%.

The sub's regular selling price, if it represents a 20% markdown is $3.75

option D.

The precise value that corresponds to the unit price paid is represented by the cost price. In some stock market theories, this value is utilized to establish the value of stock holdings and is used as a key determinant of profitability. The precise value that corresponds to the unit price paid is represented by the cost price.

The amount a buyer pays for a good or service is known as the selling price. Depending on the price that consumers are prepared to pay, the seller is willing to take, and how competitive the price is in relation to other companies in the market, it may change.

Given,

ALGEBRA Diego's Subs is offering $0.75 off its foot-long meatball sub.

Then, C.P-S.P= 0.75

S.P-C.P= 0.75

And also given that it represents 20% mark down.

Then,

((C.P-S.P)/C.P)×100=% mark down

((C.P-S.P)/C.P)×100=20%

(0.75×100)/C.P=20

The point Q'(x, y) = (- 1.5, - 1.5) is located in quadrant III and 3 units away from point Q(x, y) = (1.5, - 1.5).

In this question we find the location of an ordered pair on the coordinate plane and we are asked to find a possible solution that is in quadrant III and three units away from the original point.

A point (x, y) is in the quadrant III if x < 0 and y < 0 and we can determine a resulting point by using the following translation formula:

(x, y) → (x - 3, y)

If we know that (x, y) = (1.5, - 1.5), then the resulting point is:

Q'(x, y) = (1.5, - 1.5) + (- 3, 0)

In this problem, the statement is:

If angles are right angles, then the angles have the same measure.

Hence the terms is:

For the converse statement, the hypothesis and the conclusion are exchanged, hence:

The value of x and y in the similar triangles are 10 and 12 respectively.

Two triangles are similar if they have the same ratio of corresponding sides and equal pair of corresponding angles.

In other words, similar triangles are the triangles that have corresponding sides in proportion to each other and corresponding angles equal to each other

Therefore,

∠A = ∠M

∠B = ∠P

∠C = ∠N

Hence, let's find x and y using the proportion as follows:

Step-by-step explanation:

To *increase* 24 in the ratio 2:3

To *increase* a quantity in given ratio consider new quantity and old quantity.

Formula: New quantity:old quantity=given ratio solution: let us take the new quantity as x, old quantity as 24(given) and given ratio=2:3(given)

-> x:24=2:3

-> x/24=2/3

-> Multiply with 24 on both sides to get x

-> 24*x/24=2/3*24

-> x=16

So, the *increase* of 24 in the ratio 2:3 is 16

What is digit?
A positional numeral system uses a single symbol, such as "2," or a combination of symbols, such as "25," to represent numbers. This single symbol is known as a numerical digit. The word "digit" derives from the fact that ten fingers (Latin: digiti) on each hand correspond to the ten numeral symbols used in the base-10 system, or decimal digits (Old Latin: decem, meaning "ten"). The absolute value of the base determines how many different digits are necessary for a given numeral system with just an integer base. For instance, the binary system (base 2) only needs two digits, whereas the decimal system (base 10) necessitates ten digits (0 through 9). (0 and 1).

The digits are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

There are nine options because the first digit cannot be 0. (assuming 1 can be the first digit as well as all others)

There are 10 options for the second digit, third digit, fourth digit, and fifth digit.

Markus' biweekly earnings (gross pay every two weeks) are $2,727.16.

The annual gross pay can be divided by 26 to get the biweekly earnings.

Another way to compute the biweekly earnings is by adding up the withholding taxes, deductions, and net earnings.

In practice, the net earnings are equal to the gross pay less withholding taxes and deductions.

Annual gross pay = $65,500

Payment period = biweekly (1st and 15th every month)

Social Security = $156.19

Medicare =            36.53

Federal tax  =     445.96

Total withholding = $636.68

Retirement = $45

Health Insurance = $200

It is given in the question that 3.185× 10¹⁷ is divided by 9.1×10⁸

we can write 3.185×10×10¹⁶ which equals 31.5×10¹⁶.

Now dividing 31.5×10¹⁶ by 9.1×10⁸ we get 3.46×10⁸.

Now multiplying  3.185× 10¹⁷ with 9.1×10⁸ we get 28.98×10²⁵

Converting 28.98×10²⁵ in scientific notation we get 2.9×10²⁶.

Numbers that are either too large or too little to be conveniently stated in decimal form can be expressed using scientific notation and known as standard form in the UK .

In scientific notation, a representation of a number that is a power of ten can also be written with equal ease. Additionally, you'll see that the amount of zeros in a regular decimal expression is exactly equal to the power to which 10 is raised.

Any time a number is expressed in words, it must first be written down as a regular decimal number before being converted. "Ten million" becomes "10,000,000" and vice versa.Ten million is written in powers of ten notation because there are seven zeros in all.

The coordinates of the image of the point (−9,−3) under the same translation will be (-7,-5).

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

It is given that the image of the point (-3, -6) under a translation is (-1, -8).

The coordinate by which the first given condition is translated as,

(-3, -6) - (x,y) =  (-1, -8)

(x,y) = (-3, -6) - (-1, -8)

(x,y) =(-3-(-1), -6-(-8)

(x,y) =(-3+1),(-6+8)

(x,y) =(-2,+2)

The coordinates of the image of the point (-9, -3) are under the same translation obtained as,

=(−9,−3)- (-2,+2)

Answer:

Step-by-step explanation:

Marking something up by 100% means doubling the price. Let's do this step first:

863.57 * 2 = 1727.14

Next, the discount is 40%

I would find this by taking the 10% value, multiplying that by 4 and subtracting that from our new value

10% = 172.714

40% = 690.856

Now our newest value:

1727.14 - 690.856

1036.284

Round to 2 decimal places (as is proper when dealing with cents):
