The total price of the pick up truck is $27,241.

What is mathematic expression?

A mathematical expression is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Base price = $22,225.

Additional options pricing,

6-speed transmission =  $2,908

cruise control = $240

trailer towing package = $230

power windows =  $738

destination charge = $900

All the other charges will be added to the base price if a person chooses all the options available, therefore,

= 22,225 + 2,908 + 240 + 230 + 738 + 900

= $27241

Therefore, The total price of the pick up truck is $27,241.

Step-by-step explanation:

Sorry couldnt type the root symbol on my ipad.

Answer:

x= 5/12,y=− 5/4

​

Step-by-step explanation:

To solve a pair of equations using substitution, first solve one of the equations for one of the variables. Then substitute the result for that variable in the other equation.

6x−12y=24,4x+2y=8

Choose one of the equations and solve it for x by isolating x on the left hand side of the equal sign.

6x−12y=24

Add 12y to both sides of the equation.

6x=12y+24

Divide both sides by 6.

x= 6/1 (12y+24)

Multiply  6

1 times 24+12y.

x=2y+4

Substitute 4+2y for x in the other equation, 4x+2y=8.

4(2y+4)+2y=8

Multiply 4 times 4+2y.

8y+16+2y=8

Add 8y to 2y.

10y+16=8

Subtract 16 from both sides of the equation.

10y=−8

Divide both sides by 10.

y=− 5/4

​Substitute − 5/4  for y in x=2y+4. Because the resulting equation contains only one variable, you can solve for x directly.

x=2(− 5/4 )+4

Multiply 2 times − 5/4 .

x=− 5/8 +4

Add 4 to − 5/8 .

x= 5/12

6/7 of people are not having a disease, the whole is 1 so the difference is:

2/3 of those having a disease is:

15 people are the 1/7 fraction of total people referred to quarantine.

The total number is:

3/5 of 105 people are male, that is:

Number of female is:

Answer:

[tex]\sf (i) \quad \dfrac{1}{7}[/tex]

[tex]\sf (ii) \quad \dfrac{2}{21}[/tex]

[tex]\sf (iii) \quad 315\:people[/tex]

[tex]\sf (iv) \quad 126\: females[/tex]

Step-by-step explanation:

If 6/7 of people who are quarantined do not have the disease then the fraction of people that do have the disease is:

[tex]\begin{aligned} \implies 1-\dfrac{6}{7} & =\dfrac{7}{7}-\dfrac{6}{7}\\\\ & =\dfrac{7-6}{7}\\\\ & =\dfrac{1}{7}\end{aligned}[/tex]

Therefore, 1/7 of people in quarantine have the disease.

We are told that 2/3 of the people who have the disease come from abroad.  Therefore, the fraction of diseased people coming from abroad is 2/3rds of the diseased people:

[tex]\begin{aligned} \implies \dfrac{2}{3} \textsf{ of }\dfrac{1}{7} & = \dfrac{2}{3} \times \dfrac{1}{7}\\\\ & = \dfrac{2 \times 1}{3 \times 7}\\\\ & = \dfrac{2}{21}\end{aligned}[/tex]

Therefore, the fraction of diseased people who have come from abroad is 2/21.

We are told that 15 people who have the disease do not come from abroad.  So if 2/3 of the people who have the disease come from abroad, then 1/3 of the people who have the disease do not come from abroad.  Remember that 1/7 of the total people have the disease.

[tex]\begin{aligned} \implies \dfrac{1}{3} \textsf{ of }\dfrac{1}{7} & = \dfrac{1}{3} \times \dfrac{1}{7}\\\\ & = \dfrac{1 \times 1}{3 \times 7}\\\\ & = \dfrac{1}{21}\end{aligned}[/tex]

Therefore, 1/21 of the total number of people have the disease and do not come from abroad.

Therefore, 15 people are equal to 1/21 of the total number of people:  

[tex]\implies \sf Total\:number\:of\:people=15 \times 21 = 315[/tex]

Therefore, the total number of people in quarantine is 315.

If 3/5 of the total are male, then 2/5 must be female.

[tex]\begin{aligned} \implies \dfrac{2}{5} \textsf{ of }315 & = \dfrac{2}{5} \times 315\\\\ & = \dfrac{2 \times 315}{5}\\\\ & = \dfrac{630}{5}\\\\& = 126 \end{aligned}[/tex]

Therefore, 126 females are in quarantine.

The 107th derivative of f(x) =cos(x) is sin(x).

The derivative of y = f(x) function is the rate of change of  y  with respect to the independent variable x.

Derivative is represented by [tex]\frac{d}{dx}[/tex] and

First derivative to y is given by  [tex]\frac{d}{dx}f(x) = \lim_{h\to \00} \frac{f(x+h)-f(x)}{h}[/tex]

Second derivative [tex]\frac{d^{2}y }{dx^{2} } = \frac{d}{dx} (\frac{dy}{dx} )[/tex] and so on higher derivatives can be defined.

[tex]\frac{d(sinx)}{dx} = cosx\\\frac{d(cosx)}{dx} = -sinx[/tex]

Given f(x) = cos(x)

Then the first derivative of cos(x) is [tex]\frac{d(cosx)}{dx} = -sinx[/tex]

The second derivative of cos(x) is [tex]\frac{d^{2}(cosx) }{dx^{2} } = \frac{d}{dx} (\frac{dcosx}{dx} ) = \frac{d(-sinx)}{dx} =-cosx[/tex]

Third derivative [tex]\frac{d^{3}(cosx) }{dx^{3} } = \frac{d }{dx } (\frac{d^{2} cosx}{dx^{2} } ) = \frac{d(-cosx }{dx } = sinx[/tex]

[tex]\frac{d^{4}(cosx) }{dx^{4} } = \frac{d(sinx) }{dx } = cosx\\\frac{d^{5}(cosx) }{dx^{5} } = \frac{d(cosx) }{dx } = -sinx\\\\\frac{d^{6}(cosx) }{dx^{6} } = \frac{d(-sinx) }{dx } = -cosx\\\\\frac{d^{7}(cosx) }{dx^{7} } = \frac{d(-cosx) }{dx } = sinx\\[/tex]

Eighth derivative if cos(x) is  cos(x)

and so on

Therefore , the first , fifth , ninth ,... derivative of f(x) =cos(x)  is -sin(x)

The second, sixth, tenth.... derivative of f(x) =cos(x)  is -cos(x)

The fourth , eighth , 12th,... derivative of f(x) =cos(x)  is cos(x)

We can say that very multiple of fourth derivative of f(x) =cos(x)  is cos(x)

We can write 107 as 104 + 3

As 104 is multiple of 4 therefore 104th derivative of cos(x) is cos(x)

[tex]\frac{d^{107}(cosx) }{dx^{107} } = \frac{d^{3} }{dx^{3} } (\frac{d^{104} cosx}{dx^{104} } ) \\\frac{d^{107}(cosx) }{dx^{107} } = \frac{d^{3}(cosx) }{dx^{3} } = sinx[/tex]

FALSE because they are two different ratios

Answer:

x = 21°

Step-by-step explanation:

180 - 159 = 21

Alternate angles (see image below) are equal, so x = 21

Using corresponding angles and adjacent angles concept, the value of x from the given parallel lines is 21°.

Given that, straight line m parallel to straight line n and t is the transversal.

The corresponding angles definition tells us that when two parallel lines are intersected by a third one, the angles that occupy the same relative position at each intersection are known to be corresponding angles to each other.

Here, y°=159°

Now, y°+x°=180° (Adjacent angles on straight line)

159°+x°=180°

x°=21°

Therefore, the value of x from the given parallel lines is 21°.

The values of x satisfying the condition of the quadratic function (f o g)(x) = 17 is; (2, 4)

We are given the functions;

f(x) = 2x - 3

g(x) = x² - 6x + 18

Thus;

(f o g)(x) = 2(x² - 6x + 18) - 3

= 2x² - 12x + 36 - 3

= 2x² - 12x + 33

Now, we want to find the value of x when (f o g)(x) = 17. Thus;

2x² - 12x + 33 = 17

2x² - 12x + 16 = 0

Factorizing this gives us;

(2x - 8)(x - 2) = 0

Thus;

2x - 8 = 0 or x - 2 = 0

x = 4 or 2

Answer:57.7

Step-by-step explanation:

The amount that was invested at the start of the 3 years that is the principal amount will be equal to $ 6051.098.

Let the principal amount that is invested be equal to x.

So, we get that:

P = x

Now, the time period t = 3 years.

Simple interest rate = r = 3.85 %

Amount after 3 years = A = $ 6750

A = P + ( P × r × t / 100)

6750 = x + ( x × 3.85 × 3 / 100)

6750 = x + 0.1155 x

6750 = 1.1155 x

x = 6750 / 1.1155

x = 6051.098

Therefore, we get that, the amount that was invested at the start of the 3 years that is the principal amount will be equal to $ 6051.098.
