You are just asked to figure out the commission. The rule is to place 100 underneath what is given as the %. In effect, % = x / 100 in decimal form. In this case x = 2.5

So the % is 2.5/100 = 0.025 as a decimal

So commission is 63000 * 0.025 = $1575 commission

Percentages are essentially fractions where the denominator is 100. To show that a number is a percent,  the full price of the ticket is 293.75.

Percentages are essentially fractions where the denominator is 100. To show that a number is a percent, we use the percent symbol (%) beside the number.

The cost of the ticket Arno buys is $43.68.

The discount she got for the original cost of ticket is 16%.

We need to find the original cost of the ticket.

We need to convert the percentage to a decimal number.

by dividing 16 with 100 we get the decimal value.

16%=16/100=0.16

Now, to find the original or full price of ticket, we need to multiply zero point one six with x equal to forty three point six eight.

0.16×x=43.68

Divide both sides by 0.16

x=293.75

Hence the full price of the ticket is 293.75.

Hello, you just missed one multiplicity which has a root at

[tex]x = 2[/tex]

The detailed solution is given below. Good luck!

Answer:

f(x) = 2(x - 2)²(x + 1)(x - 1)

Step-by-step explanation:

a polynomial of the 4th degree has as highest exponent for terms in x : 4

your previous attempt only gets you to x³ terms, so to a polynomial of 3rd degree.

you made the following mistakes :

you used the factor for the root (zero) at x = 2 only once, although it has a multiplicity 2 (that means it has to be used twice : the same zero solution appears twice) :

e.g. (x - 2)²

you used the same factor for the root at -1 and at +1.

no, they are different, of course, as -1 and +1 are different.

e.g.

(x + 1)(x - 1)

you miscalculated the factor to fulfill also the last criteria to have a y- intercept at (0, -8), y = f(0) = -8.

so, the equation is

f(x) = 2(x - 2)²(x + 1)(x - 1)

why ?

when x = 0, all terms are eliminated except for the last one that is the multiplication of all constant integers of the factors. and to get -8 in such a multiplication, we have already 3 negative factors (that will create a negative result), and any other factor needs to be positive to keep that negative result.

as -2, -2 (due to the ² factor we have it twice in the calculation), +1 and -1 are necessary for the roots (giving us -4 as result), we need an initial integer factor to now create the needed -8 result (2 × -4 = -8) :

2 × -2 × -2 × +1 × -1

Complete the missing terms in the arithmetic sequence shown here: 2, ,4.5, 7, 9.5, 12?

It should be noted that an arithmetic sequence has a first term and common difference.

In this case, a = first term = 2

a + 2d = 3rd term = 7

Since a + 2d = 7

2 + 2d = 7

2d = 7 - 2

2d = 5

Divide

d = 5/2 = 2.5

The common difference is 5

The second term will be:

A linear function with the same y-intercept as the one that is represented by the graph is: table 1.

In Mathematics, the slope of any linear function can be calculated by using this formula;

Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope, m = (y₂ - y₁)/(x₂ - x₁)

At points (-3, -4) and (-1, 2) from table 1, the slope of the line would be calculated as follows:

Slope, m = (2 + 4)/(-1 + 3)

Slope, m = 6/2

Slope, m = 3.

Note: The y-intercept of the line shown on the graph is equal to 5 because the x-value is zero (0) at this point.

By using point (-3, -4), the y-intercept of this line would be calculated by using the slope-intercept form:

y = mx + b

Where:

Making y-intercept (b) the subject of formula, we have:

y-intercept, b = y - mx

y-intercept, b = -4 - 3(-3)

y-intercept, b = -4 - (-9)

y-intercept, b = -4 + 9

y-intercept, b = 5.

Answer:

Step-by-step explanation:

1   note the other angle at d = 62   ( isosceles triangle)

2  x = 180 - 62 - 62 -25

Answer:

x = 31°

Step-by-step explanation:

since AB = BD then Δ ABD is isosceles with base angles congruent, so

∠ ADB = ∠ BAD = 62°

the sum of the 3 angle in Δ ABD = 180° , so

∠ ABD = 180° - 62° - 62° = 180° - 124° = 56°

∠ ABD and ∠ CBD are a linear pair and sum to 180° , so

56° + ∠ CBD = 180° ( subtract 56° from both sides )

∠ CBD = 124°

the 3 angles in Δ CBD sum to 180° , then

x + 124° + 25° = 180°

x + 149° = 180° ( subtract 149° from both sides )

x = 31°

Sarah will take 90 minutes to reach her school from her house if she continues to walk with her friend without increasing speed.

According to the question,

We have the following details:

Sarah leaves her house at 6:25 a.m.

She meets her friend at 6:45 a.m.

So, we have:

The time taken by Sarah to meet her friend after 1 mile = (6:45 - 6:25) minutes

The time take by Sarah to meet her friend after 1 mile = 20 minutes

Now, we can find Sarah's speed.

We know that the formula of speed is as follows:

Speed = distance/time

Speed = 1/20 mile/min

Now, the distance of her school from her house is 4.5 mile.

So, we have:

Time taken = distance/speed

Time taken = 4.5/(1/20) min

Time taken = 4.5*20 min

Time taken = 90 minutes

Hence, the time taken by Sarah to reach her school from her house is 90 minutes.

Answer:

Equations:
Cost equation C(x) = 100 + 5x
Sales equation S(x) = 15x

Graph provided

Solution at breakeven point i.e. where sales = costs is at x = 10 lbs

Step-by-step explanation:

Total cost = $100 capital cost of equipment + production cost of $5 per pound of soap

Cost equation C(x) = 100 + 5x  where x is the number of pounds of soaps produced

Sales Equation S(x) = 15x where x is the number of pounds of soap sold

The break-even quantity (in lbs) of soap to be sold to pay for equipment is when both equations are equal to each other

100 + 5x = 15x
==> 15x = 100 + 5x
==> 15x - 5x = 100   (subtract 5x on both sides)

==> 10x = 100

==> x = 10 lbs of soap

At this quantity, Sales and Costs are evened out

The equation in function notation is: f(x) = 3x + 9.

Slope of the line = 3

Y-intercept = 9

X-intercept is: -3.

In function notation, the equation can be written as .f(x) = mx + b, where:

Given the equation, -3x + y = 9, rewrite in function notation as:

-3x + y + 3x = 3x + 9

y = 3x + 9

f(x) = 3x + 9

Slope of the line is, m = 3.

The y-intercept of the equation is, b = 9.

To find the x-intercept, substitute y = 0 into y = 3x + 9:

Given are two parallel lines.

The two lines are parallel and are intersected by a transversal. Assume

Length: 18 in.

Width: 6 in.

We can use “x” as the width in this scenario. If the width is x, then the length is 3x, since length is three times the width. The perimeter would be length + length + width + width. Since the perimeter is 48, we could say that:

x + x + 3x + 3x = 48

Which simplifies to 8x=48

If you divide by 8 on both sides, you get

X=6. Then you Can plug 6 back into your x width and 3x length.

We have that the half life of the uranium is 2 years.

This means that it will take 2 years for the uranium to decay to half of its original value.

The formula for exponential decay is:

where y = the value after the decay

a = initial value

b = rate of decay.

t = number of years

First, we have to find b.

We have that 776 grams of uranium will decay to half its amount (388 grams) in 2 years. This means that:

Therefore, after 4 years (t = 4), the amount of uranium left will be:

That is the amount of uranium that will be left after 4 years.

The calculated area's maximum percentage relative error is approximately 1.33%.

we know that:

Area of the circular disc is given by A = πr²

consider A = πr²

Differentiate both sides with respect to r, we get

dA/dr = 2πr

⇒ dA = 2πr dr

calculate area:

A = πr²

A = π(30)²

A = 900π

A = 2826 cm²

Because of an error in measurement, the radius might actually be as big as 30+0.2 cm

= 30.2 cm

If r is increased from 30 by an amount Δr = dr = 0.2

Then the actual change in the calculated area would be :

ΔA = A(30+Δr)-A(30)

ΔA = A(30.2)-A(30)

ΔA = (30.2)²π -  900π

ΔA = 912.04π - 900π

= 12.04π cm²

So we estimated the maximum error in calculated area as 12.04π cm²

≅ 37.8 cm²

The maximum relative error in calculated area is:

ΔA/A= dA/A = 12.04π/900π

= 0.013
