Marty can make four modifications to his car. He chooses to upgrade the tires, fuel, engine, and driver using the expression 4t + 2f + 3e + 1d to calculate the total cost. Which of these values represents the total cost of these upgrades?

Answers

Answer 1

The total cost of the upgrades is $3280.

What is the total cost?

It is an economic measure that sums all expenses paid to the product, purchase, and investment. It refers to the overall cost of a product which includes both fixed and variable components of the cost. It works by allocating all the costs of doing business to the goods or services for sale. These are composed of both total fixed costs and total variable costs.

The given expression is 4t+2f+3e+1d

From the table, The values of t, f, e, and d in the cost column are 50, 40, 600, and 1200.

Substituting the values in the above equation.

4(50) + 2(40) + 3(600) + 1(1200) = 3280

Therefore, the total cost is $3280.

Write the quadratic equation in Standard From whose graph has the following: x-intercepts: -3, 0 passes through the point (2, 10)

Answers

The standard form of the quadratic equation is 6y = 5x² + 17x + 6.

What is the quadratic equation?

A quadratic equation is an equation such that there is a quadratic polynomial.

Given that the x-intercept is (-3,0). The graph passes through the point (2, 10).

Assume that the equation is y = ax² + bx + 1.

Putting x = -3 and y = 0 in y = ax² + bx + 1:

0 = a×(-3)² + b×(-3) + 1

9a - 3b + 1 = 0  ....(i)

Putting x = 2 and y = 10 in y = ax² + bx + 1:

10 = a×(2)² + b×(2) + 1

4a + 2b - 9 = 0  ....(ii)

Multiply 2 with (i) and 3 with (ii), then add them:

18a - 6b + 2 + 12a + 6b - 27 = 0

30a - 25 = 0

a = 5/6

Putting a = 5/6 in 9a - 3b + 1 = 0:

9×(5/6) - 3b + 1 = 0

15/2 - 3b + 1 = 0

17/2 =  3b

b = 17/6

Putting the value of a and b in y = ax² + bx + 1:

y = (5/6)x² + (17/6)x + 1

6y = 5x² + 17x + 6

"Twice a number, increased by three times the difference of the number and 3 is 11"

Answers

Answer:

number is 4

Step-by-step explanation:

let n be the number then twice the number is 2n and the difference of the number and 3 is n - 3 , so

2n + 3(n - 3) = 11 ← distribute parenthesis and simplify left side

2n + 3n - 9 = 11

5n - 9 = 11 ( add 9 to both sides )

5n = 20 ( divide both sides by 5 )

n = 4

As a check

twice the number is 2 × 4 = 8

increased by 3 times the difference of n and 3 is

8 + 3(4 - 3) = 8 + 3(1) = 8 + 3 = 11 ← Correct

1 1/2 cups of walnuts she will need for eight people.

In the given question,

It is Nadine’s birthday, and she is making walnut brownies for her sleepover.

She invited eight of her friends to her party.

The recipe that she is using makes twenty-four brownies, but she only wants to make eight.

The recipe for twenty-four calls for [tex]4\frac{1}{2}[/tex] cups of walnuts.

We have to find how many cups of walnuts she needs for eight people.

From the question we know that the recipe that she is using makes twenty-four brownies.

For making twenty-four brownies she needs [tex]4\frac{1}{2}[/tex] cups of walnuts.

We can write [tex]4\frac{1}{2}[/tex] in simplified form by multiplying the 4 by 2 then add the result of multiplying 4 by 2 to 1.

So [tex]4\frac{1}{2}[/tex] = 9/2

24 brownies = 9/2 cups of walnuts

So 1 brownies = (9/2)/24 cups of walnuts

We can write it as

1 brownies = 9/2×1/24 cups of walnuts

Simplifying

1 brownies = 9/48 cups of walnuts

Since she have to make eight brownies.

So 8 brownies = 9/48×8 cups of walnuts

Simplifying

8 brownies = 9/6 cups of walnuts

8 brownies = 3/2 cups of walnuts

8 brownies =1 1/2 cups of walnuts

Hence, 1 1/2 cups of walnuts she will need for eight people.

Answer:

Angle 1: 115 degrees

Angle 2: 72 degrees

Angle 3: 57 degrees

Angle 4: 18 degrees

Angle 5: 122 degrees

Step-by-step explanation:

Note: I won’t be finding the angles in order


Angle 3 plus 33 is a right angle which is 90 degrees

So we subtract

90-33=57

Angle 3: 57 degrees

Now angle 2 can be found because a triangle sum of all three angles is 180 degrees

We know 2 75 degrees and 33 so we can add them

75+33=108

Now subtract from 180

180-108=72

Angle 2 is 72 degrees

we can find angle 1 by first finding the missing angle next to it in the triangle

75+40=115

180-115=65

Now we can subtract 65 from 180 to find angle 1

180-65=115

Angle 1 is 115 degrees

Next to find angle 4 we have to find the other missing angle since we already know angle 3 is 57 degrees

The missing angle we just subtract 75 from 180 since the angles are next to each other on a flat plane

180-75=105

And now we add the 2 angles we know

105+57=162

Now subtract from 180

180-162=18

Angle 4 is 18 degrees

Now angle 4 and angle 5 plus 40 degrees is equal to 180 degrees

To find angle 5 we add 40 degrees and 18

40+18

58

Now subtract from 180

180-58

122

Angle 5 is 122 degrees

A food truck caters an event attended by 100 guests. Every guest orders one of two possible dishes: a salad or a turkey plate. The price of each meal decreases as more of that particular type are ordered. The price of a salad is $10.00 minus $0.06 for each salad ordered. The price of a turkey plate is $12.00 minus $0.02

multiplied by the square of the number of turkey plates ordered. Guests pay for their meal only after everyone has placed their order.

Using differentiation, find the maximum revenue for the food truck.

Remember that the number of meals is a positive integer. Round revenue to the nearest cent.

Answers

The Maximum Revenue, R for the food truck will be $528.056.

What is termed as maximum value?

Maximum revenue is the highest value of a function within a given set of ranges. The maximum value of the function under the entire range is known as the absolute maxima, and the minimum value is recognized as the absolute minima.

Total Guests = 100

Each guest orders 1 of 2 dishes

Salad price = $10 - 0.06x

Turkey price = $12 - 0.02y²

So x + y = 100S = 10 - 0.06x

T = 12 - 0.02y²

Revenue = sx + ty

Revenue = (10 - 0.06x)x + (12 - 0.02y²)y

y = 100 - x

Therefore, Revenue = (10 - 0.06x)² + (12 - 0.02*(100 - x)²)*(100 - x)

R = 10x - 0.06[tex]x^{2}[/tex] + (12 - 0.02*(10000 - 200x + x²))*(100 - x)

R = 10x - 0.06[tex]x^{2}[/tex] + (12 - 200 + 4x -0.02x² )*(100 - x)

R = 10x - 0.06[tex]x^{2}[/tex] + (-188 + 4x -0.02 x² )*(100 - x)

R = 10x - 0.06[tex]x^{2}[/tex] + (-188 + 4x -0.02x² )*100 -x (-188 + 4x -0.02x²)R = 10x - 0.06[tex]x^{2}[/tex] + -18800 + 400x -2x² -x (-188 + 4x -0.02x²)

R = 10x - 0.06[tex]x^{2}[/tex] + -18800 + 400x -2x² + 188x - 4x² +0.02x³ R = 10x - 0.06[tex]x^{2}[/tex] + -18800 + 588x -6x² + 0.02x³

R = -18800 + 598[tex]x[/tex] - 6.06[tex]x^{2}[/tex] + 0.02[tex]x^{3}[/tex]

Using differentiation,dR/dx = 598 - 12.12x + 0.06x²

Equating to zero,598 - 12.12x + 0.06x² = 0Dividing both sides by 2, we have:299 - 6.06x + 0.03x² = 0x = -(-6.06)/(2*0.03) + root((-6.06)² - 4*0.03*299) / 2*0.03x = 101 - root(36.7236 - 35.88) / 0.06x = 101 - 14x = 86.94 ≅ 87

Therefore, when you sell 87 salad plates and 13 turkey dishes, that is where you will make Revenue.

Revenue = (10 - 0.06*87)*87 + (12 - 0.02(13)²)*13

Revenue = 416 + 112

R ≅ $528

Jennifer Lopez met her 10 cousins at a family reunion. The number of male cousins (x) is 2 less than the number of female cousins (y). How many (male,female) cousins were there? (not including Jennifer)

Answers

Answer:

Explanation:

Given that Jennifer Lopez has 10 cousins

The number of male cousins is x

The number of female cousins is y

Since x is 2 less than y, we have:

x = y + 2 ...............................................................................(1)

The total number of cousins is 10, we have:

x + y = 10 ..............................................................................(2)

Substituting equation (1) in (2)

(y + 2) + y = 10

y + y + 2 = 10

2y + 2 = 10

Subtract 2 from both sides

2y = 10 - 2

2y = 8

Divide both sides by 2

y = 8/2 = 2

Substitute the value of y into (1)

x = 2

In the diagram, what is the relationship between segments AC and BC? Explain your answer.

Answers

In the diagram the relationship between AC and BC is that they are the hypotenuse if the right angle triangles ADC and BDC and they are equal

What is a hypotenuse?

The longest side in a right triangle is called the hypotenuse. In a right triangle, it is the side opposite the right angle.

The right triangle's hypotenuse is longer than its other two sides

When a perpendicular bisector (CD) bisects a line (in this case AB) the hypotenuse formed in the process are equal

The base and the perpendicular side, are related in accordance with the Pythagoras theorem. The square of the hypotenuse of a right triangle is the sum of the squares of its base and perpendicular side.

Hi can you help me find the correct answer to this?

Answers

x=3 , 8

Explanation

remember the square of a binomyal

[tex](a\pm b)^2=a^2\pm2ab+b^2[/tex]

Step 1

given

[tex]\sqrt{x+1}\text{ =x-5}[/tex]

we need to isolate x, so

a) rise each side to power 2

[tex]\begin{gathered} \sqrt{x+1}\text{ =x-5} \\ (\sqrt{x+1})\text{ }=(x-5)^2 \\ x+1=x^2-2*5*x+5^2 \\ x+1=x^2-10x+25 \\ subtrac\text{ x in both sides} \\ x+1-x=x^2-10x+25-x \\ 1=x^2-11x+25 \\ subtract\text{ 1 in both sides} \\ 1-1=x^2-11x+25-1 \\ hence \\ x^2-11x+24=0 \end{gathered}[/tex]

Step 2

solve the quadratic equation:

b) use the quadratic formula

[tex]\begin{gathered} it\text{ says} \\ for\text{ ax}^2+bx+c=0 \\ the\text{ solution for x is} \\ x=\frac{-b\pm\sqrt{b^2-4ac}}{2a} \end{gathered}[/tex]

so

i)let

[tex]\begin{gathered} ax^2+bx+c=x^2-11x+24 \\ so \\ a=1 \\ b=-11 \\ c=24 \end{gathered}[/tex]

ii) now, replace in the formula

[tex]\begin{gathered} x=\frac{-b\pm\sqrt{b^2-4ac}}{2a} \\ x=\frac{-(-11)\pm\sqrt{-11^2-4(1)(24)}}{2(1)} \\ x=\frac{11\pm\sqrt{121-96}}{2} \\ x=\frac{11\pm\sqrt{25}}{2}=\frac{11\pm5}{2} \\ so \\ x_1=\frac{11+5}{2}=\frac{16}{2}=8 \\ x_2=\frac{11-5}{2}=\frac{6}{2}=3 \end{gathered}[/tex]

therefore, the solutions are x= 3 and x= 8

so, the answer is

x=3 , 8

I hope this helps you
