About how many blocks tall is your model of the Empire State Building?

What is the scale factor?

Answer:

Step-by-step explanation:

The degree of a polynomial is the variable (in this case 1 variable) raised to the highest power.

Look at the first term: 19x^9

The variable is x

The highest power is 9

So the answer is 9.

Answer:

3

Step-by-step explanation:

3^1 = 3, 3^2 = 9, 3^3 =27, 3^4 =81,

3^5 = 243, etc. We see that the last digits of the powers of 3 are 3, 9, 7, and 1. If we continue this pattern, the last digit of 3^73 is 3. So if 3^73 is divided by 5, the remainder is 3.

[tex](\sqrt{2}{, 45^{\circ})[/tex]

============================================================

Explanation:

The original point is in cartesian form (x,y). We have x = 1 and y = 1 pair up together.

The radius is [tex]r = \sqrt{x^2+y^2} = \sqrt{1^2+1^2} = \sqrt{2}[/tex]

The angle theta is [tex]\theta = \tan^{-1}(y/x) = \tan^{-1}(1/1) = 45^{\circ}[/tex]

Therefore, the polar form is [tex](r, \theta) = (\sqrt{2}, 45^{\circ})[/tex]

The idea is to start at the origin while facing directly east at the angle 0 degrees. Then turn 45 degrees to the north (going counterclockwise) and then move [tex]\sqrt{2}[/tex] units away from the origin. Doing these steps will take you to the point (x,y) = (1,1)

Answer:

Net pay = $142 + $2665 = $2807

Percent withdrawn = (withdrawal ÷ net pay) × 100%

                               = (142 ÷ 2807) × 100%

                               = 5.058781617...%

                               = 5.1% (nearest tenth)

Answer:

y = -7x + 36

Step-by-step explanation:

Point-slope form: y - y1 = m(x - x1)

Substitue 8 for y1, and 4 for x1, and -7 for m:

y - y1 = m(x - x1)

y - 8 = -7(x - 4)

Solve:

y - 8 = -7(x - 4) <== distribute -7

y - 8 = -7x + 28 <== add 8 to both sides

  + 8         + 8

y = -7x + 36

Therefore, the point-slope of the line is y = -7x + 36

Check your answer using (4, 8):

y = -7x + 36

8 = -7(4) + 36

8 = -28 + 36

8 = 8

This statement is correct

Hope this helps!

The International System of Units, or Le Système International d'Unités (SI), was established in 1960. The SI system of units is essentially a modernized metric system. SI is the official system of units for science and has been adopted for commerce and technology in Canada and most other nations. The seven units upon which the SI system is based are listed in the table that follows.

Answer: B D F

Step-by-step explanation:

The statement (B), statement (D), statement (F) are true if piecewise defined function f(x) that increases over the intervals (-∞, 3) and (3,∞).

A piecewise function is one that has several curve parts in its graph.

It means that, based on the value of the input, it has countless definitions.

A piecewise function, in other words, performs differently depending on the input.

We have given a data for a piecewise function.

From the data:

[tex]\rm \lim_{n \to 3^+} f(x) = 5[/tex]

[tex]\rm \lim_{n \to 3^-} f(x) = 6[/tex]

[tex]\rm \lim_{n \to 2^+} f(x)[/tex] Does not exist because [tex]\rm \lim_{n \to 3^+} f(x)[/tex] and [tex]\rm \lim_{n \to 3^-} f(x)[/tex] are not equal.

Thus, the statement (B), statement (D), statement (F) are true if piecewise defined function f(x) that increases over the intervals (-∞, 3) and (3,∞).

The best way to solve these sorts of problems that involve two factors of unknown quantities but with certain properties is to use equations:

Let's set some variables

Now based on the information given by the question, let's set up some equations:

              ⇒ [tex]s + h = 166[/tex]

             ⇒ h = s - 54

Now lets put the equation together

  s + h = 166 -- equation 1

  h = s - 54   -- equation 2

Solve:

  Plug the value of h from equation 2 into equation 1

      s + (s - 54) = 166

        2s - 54 = 166

           2s = 220

             s = 110 -- equation 3

   Plug the value of s from equation 3 into equation 2

      h = 110 - 54 = 56

            h = 56

Therefore:

Answer:

2.7

Step-by-step explanation:

15/1 = 40/x

Cross multiply: 40/15

Divide: 2.66

Round up: 2.7

2.7 times 15= 40.5

Answer:

2hrs. 40mins.

Step-by-step explanation:

A babysitter charges a rate of $15 per hour. How long was the babysitter there if she makes $40?

x = hours she babysat

Equation:

15x = 40

Divide to isolate x:

15x = 40

/15   /15

x = 8/3 hrs.

Now, we convert into hours and minutes, since she did work for more than an hour, to earn the $15 each hour.

We know that there are 60 mins. in an hour

60 * 8/3

480/3

160 mins.

Convert into hour and mins:

1 hr. = 60 mins

160/60 = 2 40/60 ==> 2 2/3

Convert 2/3 into mins to add to the hours:

60 * 2/3

120/3 = 40

2hrs. + 40 mins.

2hrs. and 40mins

Therefore, the babysitter was there for 2hrs. 40mins.

Answer:

72

Step-by-step explanation:

Triangle area formula: A = 1/2 (B) (H)

This means the area of a triangle is half of the base times the height.

So we can plug the numbers into the formula:

A = 1/2 (16) (9)

16 x 9 is 144, divided by 1/2 is 72.

Final answer 72.

The width of the rectangle as a function of its length is w = 55/l

The formula for finding the area of a rectangle is expressed as:

A = lw

where

l is the length

w is the width of the rectangle

Given that A = 55 square inches, then;

55 = lw

w = 55/l

Hence the width of the rectangle as a function of its length is w = 55/l

[tex]4\sqrt{2b}[/tex]

Step-by-step explanation:

[tex]\sqrt{98b}-\sqrt{72b}+\sqrt{18b}[/tex]

Apply radical rule [tex]\sqrt{ab} =\sqrt{a} \sqrt{b}[/tex]:

[tex]\implies \sqrt{98}\sqrt{b} -\sqrt{72}\sqrt{b} +\sqrt{18}\sqrt{b}[/tex]

If you need the rest of the parts:

C. $4,500

D. $20,500

E. $68,000

The income tax of $5,448.

The taxable income is $102,800

The tax that is imposed on all people and corporations is called income tax. The amount of individual income taxes is determined by the individual's income. Because the burden is assumed to fall on the payers, it is typically characterised as a direct tax. Corporate income tax is charged on net profits, which are determined as the difference between allowable costs and receipts.

From the graph,

it can be observed that the taxpayer who has the taxable income of $39,800 has to pay income tax of $5,448.

Also, a taxpayer owing $21,197 means that he has to pay income tax of $21,197.

His taxable income is $102,800 as shown in the graph below.

Answer:

Step-by-step explanation:

The angle between the secant and the tangent will be half the measure of the intercepted arc. The two intercepted arcs total 1+5=6 ratio units and 360°. That means each ratio unit represents 60° of arc. The two arcs are 60° and 300°.

Then the two angles at the tangent and secant are ...

  60°/2 = 30° . . . . . . . the one marked in the attache drawing
