f(x) = 4x^3– 12x^2-x+15

A. True
B. False

Options:

A. At least $30,000

B. At most $30,000

C. Less than $30,000

D. More than $30,000

Answer:

A. At least $30,000

Step-by-step explanation:

Given the inequality :

2x + $10,000 ≥ $70,000 ;

Where x salary of an employee ;

Phrase which describes the employee's salary, x

2x + 10000 ≥ 70000

2x ≥ 70000 - 10000

2x ≥ 60000

x ≥ 60000 / 2

x ≥ 30000

Salary ,x, is greater than or equal to $30000

Step-by-step explanation:

8000 pounds is required to produce 200 lb of refined sugar

It takes 200 lb of sugar cane to produce 5 lb of refined sugar

For 1 lb of sugar cane, the number of refined sugar that will be produced is

200= 5

x= 1

cross multiply

5x= 200

x= 200/5

x= 40

The number of pounds of sugar cane required to produce 200 lb of refined sugar is

= 40 × 200

= 8,000

Hence 8000 pounds of sugar cane is required to produce 200 lb of refined sugars

Answer:

[tex]39.29\ \text{km/h}[/tex]

Step-by-step explanation:

s = Speed of the train

m = Money spent on maintanence

[tex]s\propto m^{\dfrac{1}{3}}[/tex]

Let k be the constant of proportionality so

[tex]s=k (m)^{\dfrac{1}{3}}[/tex]

Now a case is given where 25 km/hr is possible on a stretch for which 450,000 is spent so

s = 25

m = 450000

[tex]s=k (m)^{\dfrac{1}{3}}\\\Rightarrow k=\dfrac{s}{m^{\dfrac{1}{3}}}\\\Rightarrow k=\dfrac{25}{450000^{\dfrac{1}{3}}}\\\Rightarrow k=0.326[/tex]

Now when m = 1750000

[tex]s=k (m)^{\dfrac{1}{3}}\\\Rightarrow s=0.326\times 1750000^{\dfrac{1}{3}}\\\Rightarrow s=39.29\ \text{km/h}[/tex]

The maximum speed of the train would be [tex]39.29\ \text{km/h}[/tex].

Answer:

43

Step-by-step explanation:

Let

The unit digit = x

The tens digit = y

The number = 10x + y

The tens digit of a two-digit number is five more than the units digit.

y = x + 5

Seven times the sum of the digits of this number is 3 less than the number itself.

7(x + y) = 10x + y - 3

7x + 7y = 10x + y - 3

Find the number.

We substitute x + 5 for y

7x + 7(x + 5) = 10x + (x + 5) - 3

7x + 7x + 35 = 10x + x + 5x - 3

14x + 35 = 11x + 5x - 3

Collect like terms

35 + 3 = 11x + 5x -14x

38 = 16x - 14x

38 = 2x

x = 38/2

x = 19

Solving for y

y = x + 5

y = 19 + 5

y = 24

The number = 19 + 24

= 43

Step-by-step explanation:

If he starts off with $50 then these are the steps

$50 - $1.50 = $48.50 for 1 MP3

$48.50 - $1.50 = $45.50 for 3

then repeat that until we have $12

it doesnt give us exactly $12 but it gives us $12.50 reminder

hi

if the twi lines are  parallel , they have the same slope.

So  slope  is   1/2.  

equation of a line is  :  mx +p

The line goes throught  (-2 ; 4)

We have    1/2 ( -2)  + p =  4

                   -  2/2  +p = 4

                   -1 +p = 4

                       p = 4+1

                       p = 5

equation of the line  is   y = 1/2x +5

The domain of the function is [ - 6 , ∞ ]

The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.

here, we have,

A radical function is the one provided.

It should be noted that a radical function can only be specified for values that will result in the radicand being larger than or equal to zero.

As a result, either the radicand of the provided function must be larger than or equal to zero, or:

Thus we can write it as

x + 6 ≥ 0

subtract 6 from both LHS and RHS

x + 6 - 6 ≥ 0 - 6

x ≥ - 6

Therefore the domain of the function is [ - 6 , ∞ ]

Answer: $1179.75

Step-by-step explanation:

Percentage of commission = 5.5%

Value of property = $21,450

Commission = Percentage commission × Value of property

= 5.5% × $21,450

= 5.5/100 × $21,450

= 0.055 × $21,450

= $1179.75

The commission is $1179.75

Step-by-step explanation: An order to a bank to pay a stated sum from the drawer's account, written on a specially printed form.

Answer:

$992.00

Step-by-step explanation:

Where:

I = P x r x t

P is the principal amount, $800.00.

r is the interest rate, 6% per year, or in decimal form, 6/100=0.06.

t is the time involved, 4....year(s) time periods.

So, t is 4....year time periods.

To find the simple interest, we multiply 800 × 0.06 × 4 to get that:

The interest is: $192.00

Usually, now, the interest is added onto the principal to figure some new amount after 4 year(s),

or 800.00 + 192.00 = 992.00. For example:

If you borrowed the $800.00, you would now owe $992.00

If you loaned someone $800.00, you would now be due $992.00

If owned something, like a $800.00 bond, it would be worth $992.00 now.
