a) Janet would save $17.20 - $5.60733 = $11.59 by borrowing the money for the printer at 6% to take advantage of the cash discount. b) , the difference in the final payment between choices 1 and 2 is $1,107.60.

a. The cash discount on the printer is calculated as 2% of the list price:

Cash discount = 2% * $860 = $17.20

Using the formula:

Interest = Principal * Rate * Time

Principal = Amount borrowed = List price - Cash discount = $860 - $17.20 = $842.80

Rate = 6% per year = 6%/100 = 0.06

Time = 30 days (since the terms are 2/10, n/30)

To convert the interest to a 360-day basis, we use the formula:

Interest = Principal * Rate * (Time/360)

Interest = $842.80 * 0.06 * (30/360) = $5.60733

Therefore, Janet would save $17.20 - $5.60733 = $11.59 by borrowing the money for the printer at 6% to take advantage of the cash discount.

b. Choice 1 for the computer involves paying $150 per month for 17 months, with the 18th payment paying the remainder of the balance. Choice 2 involves paying 6% interest for 18 months in equal payments.

For choice 1:

Remaining balance = List price - (17 * Monthly payment)

Remaining balance = $4,020 - (17 * $150) = $4,020 - $2,550 = $1,470

For choice 2:

Interest = Principal * Rate * Time

Principal = Amount borrowed = List price = $4,020

Rate = 6% per year = 6%/100 = 0.06

Time = 18 months

To convert the interest to a 12-month basis, we use the formula:

Interest = Principal * Rate * (Time/12)

Interest = $4,020 * 0.06 * (18/12) = $362.40

The final payment difference between choices 1 and 2 is:

Final payment difference = Remaining balance - Interest

Final payment difference = $1,470 - $362.40 = $1,107.60

Therefore, the difference in the final payment between choices 1 and 2 is $1,107.60.

Rounding to the nearest cent, the estimated value of the vehicle after 4 years is approximately $23,726.20..

To estimate the value of the vehicle after 4 years, we can use the given equation A = 39500(0.86)^t, where A represents the value of the vehicle and t represents the number of years.

Substituting t = 4 into the equation:

A = 39500(0.86)^4

A ≈ 39500(0.5996)

A ≈ 23726.20

Rounding to the nearest cent, the estimated value of the vehicle after 4 years is approximately $23,726.20.

This estimation is based on the assumption that the vehicle's value decreases by 14% each year. The equation A = 39500(0.86)^t models the exponential decay of the vehicle's value over time. By raising the decay factor of 0.86 to the power of 4, we account for the 4-year period. The final result suggests that the value of the vehicle would be around $23,726.20 after 4 years of ownership.

The solution is

A) The vertical asymptote of the function f ( x ) is = -3

B) The holes in the graph of f ( x ) = ( 0 , 6 )

C) The horizontal asymptote of the function f ( x ) is = 6

What are Asymptotes?

An asymptote is a line that a curve approaches but never touches. A line where the graph of a function converges is known as an asymptote. When graphing functions, asymptotes are typically not required

There are 3 types of asymptotes

Horizontal asymptote (HA) - It is a horizontal line and hence its equation is of the form y = k. Horizontal Asymptote is when the function f(x) is tending to zero

Vertical asymptote (VA) - It is a vertical line and hence its equation is of the form x = k. Vertical asymptotes are defined when the denominator of a rational function tends to zero

Slanting asymptote (Oblique asymptote) - It is a slanting line and hence its equation is of the form y = mx + b

Given data ,

Let the function be f ( x ) = ( 6x² + 6x - 36 ) / ( x² + 3x )

A)

Now , to find the vertical asymptote

To find the vertical asymptote of a rational function, we simplify it first to lowest terms, set its denominator equal to zero, and then solve for x values

So , when x² + 3x = 0

x ( x + 3 ) = 0

So , x + 3 = 0

x = 0 is a hole in the graph

x = -3 is the vertical asymptote

B) The hole in the graph is ( 0 , 6 )

C)

Now , to find the horizontal asymptote

If both the polynomials have the same degree, divide the coefficients of the leading terms

So , 6x² and x² are the polynomials having the same degree

So , the coefficients are 6 and 1

y = (leading coefficient of numerator) / (leading coefficient of denominator)

y = 6 is the horizontal asymptote

Hence ,

A) The vertical asymptote of the function f ( x ) is = -3

B) The holes in the graph of f ( x ) = ( 0 , 6 )

C) The horizontal asymptote of the function f ( x ) is = 6

Step-by-step explanation:

First, make sure you always solve from left to right when doing this. For this situation we need PEMDAS. This stands for: Parenthesis, Exponents, Multiplication/Division, and Addition/Subtraction. These are the steps that we need to follow to answer this question.

1.) First, we solve for the parenthesis. We can take the parenthesis down once we solve for that part. 2 + 1 = 3. Now we have: -3 ÷ 3 x 2 + 4.

2.) There are no exponents, so we move onto to multiplication from left to right. -3 ÷ 3 = -1. So, now we have -1 x 2 + 4.

3.) Now we do the right side of the problem with the multiplication. -1 x 2 = -2. Now we have -2 + 4.

4.) Because the larger number is positive, that means that the answer will be positive. So -2 + 4 (or 4 -2) = 2.

So, -3 ÷ (2 + 1) x 2 + 4 = 2.

Answer: 7.5

Step-by-step explanation:

the tank is 15 gallons and you can get 13 percent ethanol or 69 percent ethanol, so you simply just get 7.5gallons of 69 percent and then 7.5 gallons of 13 percent

.69 divided by 15 is .046

.13 divided by 15 is .008

The amount of 69% percent ethanol fuel should you use so that your tank is 40 percent ethanol is equivalent to 4.35 gallons.

Given is that a car has a 15 gallon tank and can run on fuel with added

ethanol. The fuel contains either 13 percent ethanol or 69 percent

ethanol.

The amount of 69% percent ethanol fuel should you use so that your tank is 40 percent ethanol is given by -

{x} = 69% of 15 - {40% of 15}

{x} = (69/100 x 15) - (40/100 x 15)

{x} = 10.35 - 6

{x} = 4.35

Therefore, the amount of 69% percent ethanol fuel should you use so that your tank is 40 percent ethanol is equivalent to 4.35 gallons.

Answer:

(2a^3a^4)^5 simplifies to 32a^35.

Step-by-step explanation:

To simplify (2a^3a^4)^5, we can use the properties of exponents which states that when we raise a power to another power, we can multiply the exponents. Therefore, we can rewrite the expression as:

(2a^3a^4)^5 = 2^5 * (a^3a^4)^5

Next, we can simplify the expression inside the parentheses by multiplying the exponents:

a^3a^4 = a^(3+4) = a^7

Substituting this into our expression, we get:

(2a^3a^4)^5 = 2^5 * (a^3a^4)^5 = 2^5 * a^35

Finally, we can simplify this expression by using the property of exponents that states that when we multiply two powers with the same base, we can add their exponents. Therefore, we can rewrite the expression as:

2^5 * a^35 = 32a^35

Therefore, (2a^3a^4)^5 simplifies to 32a^35.

All 3 angles add up to 180 degrees.

so 40 + 2x + 3x = 180

40 + 5x = 180

5x = 140

x = 28

So angle A = 2x = 2(28) = 56 degrees.

Answer: 56°

Step-by-step explanation:

We know that a triangle's angles add up to 180 degrees. We will create an equation to help us solve for x using this information.

     Given:

           2x + 3x + 40 = 180

     Combine like terms:

           5x + 40 = 180

     Subtract 40 from both sides of the equation:

           5x = 140

     Divide both sides of the equation by 5:

           x = 28

Next, we will substitute this value of x into the expression for ∠A.

     ∠A = 2x = 2(28) = 56°

Answer:

85.36 far north from the center

10.36 far east from the center

Step-by-step explanation:

The extra direction taken in the north side is x

X/sin(360-315)=50/sin 90

Sin 90= 1

X/sin 45= 50

X= sin45 *50

X= 0.7071*50

X= 35.355 steps

X= 35.36

Then the west direction traveled

West =√(50² - 35.355²)

West = √(2500-1249.6225)

West= √1250.3775

West= 35.36 steps

But this was taken in an opposite west direction

From the center

He is 35.36 +50

= 85.36 far north from the center

And

25-35.36=-10.36

10.36 far east from the center

When p, the probability of success, is zero in a binomial distribution, the probability of getting exactly k successes in n trials is also zero for all values of k except when k is zero (i.e., when there are no successes).

So, in the case of (0.3)^0, the result would be 1, because any number raised to the power of 0 is equal to 1. Therefore, the probability of getting zero successes in a binomial distribution when the probability of success is 0.3 is 1.

Answer:

f(x) = x³ - 4x + 6

f'(x) = 3x² - 4

a) f'(2) = 3(2²) - 4 = 12 - 4 = 8

6 = 8(2) + b

6 = 16 + b

b = -10

y = 8x - 10

b) 3x² - 4 = 0

3x² = 4, so x = ±2/√3 = ±(2/3)√3

= ±1.1547

f(-(2/3)√3) = 9.0792

f((2/3)√3) = 2.9208

c) 3x² - 4 = 8

3x² = 12

x² = 4, so x = ±2

f(-2) = (-2)³ - 4(-2) + 6 = -8 + 8 + 6 = 6

6 = -2(8) + b

6 = -16 + b

b = 22

y = 8x + 22

f(2) = 6

y = 8x - 10

The equation perpendicular to the tangent is y = -1/8x + 25/4

-The smallest slope on the curve is 2.92

The curve has the smallest slope at the point (1.15, 2.92)

The equations at tangent points are y = 8x + 16 and  y = 8x - 16

From the question, we have the following parameters that can be used in our computation:

y = x³ - 4x + 6

Differentiate

So, we have

f'(x) = 3x² - 4

The point is (2, 6)

So, we have

f'(2) = 3(2)² - 4

f'(2) = 8

The slope of the perpendicular line is

Slope = -1/8

So, we have

y = -1/8(x - 2) + 6

y = -1/8x + 25/4

We have

f'(x) = 3x² - 4

Set to 0

3x² - 4 = 0

Solve for x

x = √[4/3]

x = 1.15

So, we have

Smallest slope = (√[4/3])³ - 4(√[4/3]) + 6

Smallest slope = 2.92

So, the smallest slope is 2.92 at (1.15, 2.92)

Here, we set f'(x) to 8

3x² - 4 = 8

Solve for x

x = ±2

Calculate y at x = ±2

y = (-2)³ - 4(-2) + 6 = 6: (-2, 0)

y = (2)³ - 4(2) + 6 = 6: (2, 0)

The equations at these points are

y = 8x + 16

B) We used an algebraic approach to to solve the formula for \(b_{1}\).  \(b_{1} = \frac{2\cdot A}{h}-b_{2}\)

C) The length of the other base of the trapezoid is 20 centimeters.

D) We can find their lengths as both have the same length and number of variable is reduced to one, from \(b_{1}\) and \(b_{2}\) to \(b\). \(b = \frac{A}{h}\)

Step-by-step explanation:

A) The formula for the area of a trapezoid is:

\(A = \frac{1}{2}\cdot h \cdot (b_{1}+b_{2})\) (Eq. 1)

Where:

\(h\) - Height of the trapezoid, measured in centimeters.

\(b_{1}\), \(b_{2}\) - Lengths fo the bases, measured in centimeters.

\(A\) - Area of the trapezoid, measured in square centimeters.

We proceed to clear the height of the trapezoid:

4) \(h = \frac{2\cdot A}{b_{1}+b_{2}}\) Existence of multiplicative inverse/Modulative property/Definition of division/Result

If we know that \(A = 91\,cm^{2}\), \(b_{1} = 16\,cm\) and \(b_{2} = 12\,cm\), then height of the trapezoid is:

\(h = \frac{2\cdot (91\,cm^{2})}{16\,cm+12\,cm}\)

\(h = 6.5\,cm\)

The height of the trapezoid is 6.5 centimeters.

B) We should follow this procedure to solve the formula for \(b_{1}\):

1) \(A = \frac{1}{2} \cdot h \cdot (b_{1}+b_{2})\) Given.

2) \(A = 2^{-1}\cdot h \cdot (b_{1}+b_{2})\) Definition of division.

5) \(\frac{2\cdot A}{h} +(-b_{2}) = [b_{2}+(-b_{2})] +b_{1}\) Definition of division/Compatibility with addition/Commutative and associative properties

6) \(b_{1} = \frac{2\cdot A}{h}-b_{2}\) Existence of additive inverse/Definition of subtraction/Modulative property/Result.

We used an algebraic approach to to solve the formula for \(b_{1}\).

C) We can use the result found in B) to determine the length of the remaining base of the trapezoid: (\(A= 215\,cm^{2}\), \(h = 8.6\,cm\) and \(b_{2} = 30\,cm\))

\(b_{1} = \frac{2\cdot (215\,cm^{2})}{8.6\,cm} - 30\,cm\)

\(b_{1} = 20\,cm\)

The length of the other base of the trapezoid is 20 centimeters.

D) Yes, we can find their lengths as both have the same length and number of variable is reduced to one, from \(b_{1}\) and \(b_{2}\) to \(b\). Now we present the procedure to clear \(b\) below:

1) \(A = \frac{1}{2} \cdot h \cdot (b_{1}+b_{2})\) Given.

2) \(b_{1} = b_{2}\) Given.

3) \(A = \frac{1}{2}\cdot h \cdot (2\cdot b)\) 2) in 1)

4) \(A = 2^{-1}\cdot h\cdot (2\cdot b)\) Definition of division.

5) \(A\cdot h^{-1} = (2\cdot 2^{-1})\cdot (h\cdot h^{-1})\cdot b\) Commutative and associative properties/Compatibility with multiplication.

Step-by-step explanation:

In this question we are given with two interior angles of the triangle that are 40° and 70° , also we are given an exterior angle that is (5x + 10)°. And we are asked to find the value of angle x.

Solution :-

For finding the value of angle x , we have to use exterior angle property of triangle which states that sum of opposite interior angles of triangle is equal to the given exterior angle. So :

Step 1: Making equation :

\( \longmapsto \: \sf{40 {}^{°} + 70 {}^{°} = (5x + 10) {}^{°} }\)

Solving :

\( \longmapsto \: \sf{110 {}{°} = (5x) {}^{°} +10 {}^{°} }\)

Step 2: Subtracting 10 on both sides :

\( \longmapsto \sf{ 110 {}^{°} - 10 {}^{°} = 5x + \cancel{10 {}^{°}} - \cancel{10 {}^{°} } }\)

We get ,

\( \longmapsto \sf{(5x ){}^{°} = 100 {}^{°} }\)

Step 3: Dividing both sides by 5 :

\( \longmapsto \dfrac{ \cancel{5}x {}^{°} }{ \cancel{5}} = \dfrac{ \: \: \: \: \cancel{ 100} {°}^{} }{ \cancel{5} }\)

On cancelling , we get :

\( \longmapsto \underline{\boxed{\red{\sf{ \bold{ x = 20 {}^{°} }}}}} \: \: \bigstar\)

Verification :-

For verifying sum of both the interior angles is equal to given exterior angles. As we get the value of x as 20 we need to substitute it's value in place x and then L.H.S must be equal to R.H.S :

Therefore , our answer is correct .
