According to the concept of quadratic equation, the minimum cost for the x ray machine is $17, 484

Quadratic equation:

Basically, the polynomial equation with highest degree of two is called a quadratic equation.

The general equation is given by ax² + bx + c = 0, where a ≠ 0.

Given,

A medical equipment industry manufactures X-ray machines. The unit cost C (the cost in dollars to make each X-ray machine) depends on the number of machines made. If .x machines are made, then the unit cost is given by the function C (x)=0.5x²-320x+68,684.

Here we need to find the minimum unit cost.

Here we know that the standard form of a quadratic is given by:

=> ax² + bx + c

From this function, we have to calculate the value of x as,

=> x = -b/ 2a

While we compare the standard form with the given function,

=> C (x)=0.5x²-320x+68,684.

Then we get the value of

=> a = 0.5

=> b = -320

=> c = 68,684

So, the value of x is calculated as,

=> x = -(-320) / 2(0.5)

=> x = 320 / 1

=> x = 1

Now, we have to plug this value into original function would give us the minimum (unit cost):

=> C(320) = 0.5(320)²- 320 (320) + 68,684.

=> C(320) = 0.5(102400) - 102400 + 68, 684

=> C(320) = 51200 - 102400 + 68684

=> C(320) = 17, 484

Therefore, the minimum unit cost is $17, 484

Answer: The sum is 55/28.

Alternate Answer: 1 27/28

Step-by-step explanation:

In this equation, the common denominator between the three fractions would be twenty eight.

5/7 converts to 20/28

1/2 converts to 14/28

3/4 converts to 21/28

After adding all the new fractions together, you get 55/28.

Answer: the probability that it will not rain is 70% (you might need to do 7/10)

the odds in favor of the rain occuring is 30% (again, you might need to do 3/10)

Step-by-step explanation:

since the probability that it will rain is 3/10, there is only 7/10 left, so it is more likely to not rain than to rain.

Since it will rain 3/10 times, it is 30% for the second problem

Answer:

1,000 x 550.343978 = 550343.978

Step-by-step explanation:

a polynomial of degree 4 must have 4 zeroes.

when we know these zeroes, we can define the polynomial by the factors defining these zeroes.

after all, a multiplication of several factors can only be zero, if at least one of the factors is zero.

we have 3 zeroes at x = -1. and 1 zero at x = 0.

so,

f(x) = (x + 1)(x + 1)(x + 1)x

you see ? this will only be zero, if x = -1 or x = 0. and -1 is built in as zero 3 times.

let's do the multiplications :

(x + 1)(x + 1) = x² + 2x + 1

(x + 1)x = x² + x

(x² + 2x + 1)(x² + x) = x⁴ + x³ + 2x³ + 2x² + x² + x =

= x⁴ + 3x³ + 3x² + x

f(x) = 1x⁴ + 3x³ + 3x² + 1x

The cost of the gas in dollars per gallon would be = $5.3 per gallon.

Liters can be converted to gallon as 1 liter = 0.264 gallon.

On the first day, the cost of gasoline = 1.28 euro per liter

On the first day, the worth of £1 = $ 1.09

Which means, if £1 = $1.09

£ 1.28 = $x

Make $x the subject of formula;

$x = 1.28 × 1.09/1

$x = $1.40

Which means that on the first day, the cost of gasoline in dollars = $1.40

To convert liters to gallon;

1 liter = 0.264 gallon

If $1.40 = 0.264 gallon

$x = 1 gallon

make $x the subject of formula;

$x = 1×$1.40/0.264

$x = 5.3

Therefore, the cost of gasoline in dollar per euro = $5.3 per gallon.

The depreciation for the first year is $28,800.

If the equipment is sold for $8,860 at the end of year 2, the loss on the sale is $-14,180.

Depreciation is the method used in expensing the cost of an asset. The double declining method is an exponential method that is used to expense the cost of an asset.

Depreciation expense using the double declining method = Depreciation factor x cost of the asset

Depreciation factor for the double declining method = 2 x (1/useful life)

Depreciation expense in year 1 = (2 / 10) x $36,000 = $7,200

Book value at the beginning of year 2 = cost of the asset - depreciation in year 1

$36,000 - $7,200 = $28,800

Depreciation in year 2 = (2/10) x  $28,800 = $5,760

Book value at the end of year 2 = book value at the end of year 1 - depreciation in year 2

$28,800 - $5,760 = $23,040

Loss = sales price - cost price

Loss = $8,860 - $23,040 = $-14,180

Answer: 111/250

Step-by-step explanation:

Step 1: Write down the percent divided by 100 like this:

44.4% = 44.4/100

Step 2: Multiply both top and bottom by 10 for every number after the decimal point:

As we have 1 digit after the decimal point, we multiply both numerator and denominator by 10, or, simply shift 1 decimal place to the right. So,

44.4/100 = (44.4 x 10)/(100 x 10) = 444/1000.

Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(444,1000) = 4. So,

The equation of the line that passes through the point P(1/3,4) and has no slope is y = 4.

According to the question,

We have the following information:

Point through which line is passing = (1/3,4)

Slope of the line = 0

We know that the following formula is used to find the equation of the line passing through a point:

y-y' = m(x-x')

We have x' = 1/3 and y' = 4.

y-4 = 0(x-1/3)

y-4 = 0

Adding 4 on both sides of the equation:

y = 4

Hence, the equation of the line that passes through the point P(1/3,4) and has no slope is y = 4.

Answer:

Step-by-step explanation:

You want to know the amount of interest cost subsidized by the Department of Education during the 4.5-year non-payment period on an $8000 subsidized federal loan at 4.29%.

The interest accrued on the loan amount is found by the simple interest formula:

  I = Prt

The principal is $8000, the rate is 4.29%, and the time period is the non-payment period, 4.5 years. The interest is ...

  I = $8000·0.0429·4.5 = $1544.40

The DoE will subsidize $1544.40 in interest during the non-payment period.

__

Additional comment

For the purpose of this problem, the 10-year period of the loan is irrelevant, as we're only concerned with the 4.5 year period before repayment starts. Because the loan is subsidized, that interest is never "capitalized" and is not due to be repaid by the borrower.

He needs 10 litres of solution of 40% and 20 litres of 70% solution to make 30 litres of 60% acid solution.

According to the question,

We have the following information:

Gabe Amodeo, a nuclear physicist, needs 30 liters of a 60% acid solution. He currently has a 40% solution and a 70% solution.

Now, let's take x litres of 40% solution and y litres of 70% solution.

So, we have the following expressions:

x+y = 30

x = 30-y ....(1)

40x/100 + 70y/100 = 30*60/100

Dividing 100 on the numerator by 100 on denominator:

40x+70y = 1800

Dividing both sides by 10:

4x+7y = 180

Putting the value of x from equation 1:

4(30-y)+7y = 180

120-4y+7y = 180

120+3y = 180

Subtracting 120 from both the sides:

3y = 180-120

3y = 60

y = 60/3

y = 20

Now, putting this value of y in equation 1:

x = 30-y

x = 30-20

x = 10

Hence, he needs 10 litres of 40% solution and 20 litres of 70% solution to make 30 litres of 60% acid solution.

Answer:

Mai made 7 batches of pink paint.

Mai used 49 cups of white paint.

Step-by-step explanation:

Part 1. Every 2 cups of red paint are 1 batch of pink paint. This means to find the number of batches of pink paint Mai made, we need to divide 14/2. 14/2 = 7. This means she made 7 batches of pink paint.

Part 2. For every 2 cups of red paint, there are 7 cups of white paint.

For every 1 cup of red paint, there are 3.5 cups of white paint.

This means that we need to multiply 14 x 3.5.

14 x 3.5 = 49.

This means she used 49 cups of white paint.
