Answer: 5.00x - 2.25x = 5000

Step-by-step explanation:

If function f(x) = (x+3)(3x-5) - 4, the value of f(3) - f(-2) is 35

The function is

f(x) = (x+3)(3x-5) - 4

We have to find the value of f(3) - f(-2) ,to find that find the value of f(3) and f(-2) separately.

The function is

f(x) = (x+3)(3x-5) - 4

Substitute the values in the equation

f(3) = (3+3)(3×3 - 5) - 4

= (6) × (9-5) - 4

= 6 × 4 -4

= 24 - 4

= 20

The value of f(3) = 20

f(-2) = (-2+3)(3×-2 - 5) - 4

= 1 × (-6-5) -4

= 1 × (-11) - 4

= -11 - 4

= -15

The value of f(-2) = -15

Then,

f(3) - f(-2) = 20 - (-15)

= 20 + 15

= 35

Hence, if function f(x) = (x+3)(3x-5) - 4, the value of f(3) - f(-2) is 35

The solution to the equation 5x - 5 = 15 in the replacement set is x = 4

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

5x - 5 = 15

The replacement set is given as

{0,1, 2, 3, 4}

So, we replace the variables using the elements in the replacement set

When x = 0, we have

5(0) - 5 = 15

-5 = 15 -- false

When x = 1, we have

5(1) - 5 = 15

0 = 15 -- false

When x = 2, we have

5(2) - 5 = 15

5 = 15 -- false

When x = 3, we have

5(3) - 5 = 15

10 = 15 -- false

When x = 4, we have

5(4) - 5 = 15

15 = 15 -- true

Hence, the value of the equation is x = 4

TU = 2x + 9

= 2 (6) + 9

= 12 + 9

TU = 21

Sandy earn 306.9 dollars in commission and 1739.1 dollars in hourly wages.

Sandy works at a clothing store. She makes $9 per hour plus earns 15% commission on her sales.

She worked 71 hours over the last two weeks and had a total of $2,046 in sales before taxes.

The amount she will earn in her hourly wages and commission is as follows:

amount earn in commission = 15% of 2046

amount earn in commission = 15 / 100 × 2046

amount earn in commission = 30690 / 100

amount earn in commission = 306.9 dollars

Therefore,

amount earn in hourly wages = 2046 - 306.9

According to the question,

We have the following expression:

[tex]x^{2}[/tex] -3x/2

Now, in the given four options, we only have two perfect squares which 9/16 and 16/9.

Now, 9/16 is the square of 3/4.

So, we will first solve it using 9/16:

[tex]x^{2}[/tex]-3x/2+9/16

Now, this formula is of identity [tex](a-b)^{2}[/tex] where we have a = x and b = 3/4.

Answer:

Step-by-step explanation:

You have a total of 114 legs among hippos and birds, of which there are a total of 42. You want the number of each kind of animal.

Let h represent the number of hippos. Then 42-h is the number of birds, and the total number of legs is ...

  4h +2(42 -h) = 114

Simplifying the equation gives ...

  2h +84 = 114

  2h = 30 . . . . . . subtract 84

Answer:

x° = 34°

Step-by-step explanation:

First, find the interior angle supplementary to the given exterior angle 124°.

I will label it y.

124° + y° = 180°

y° = 180° - 124°

y° = 56°

Next, solve for x° by equating the sum of the interior angles of the triangle to 180° and plugging in the y-value that we just solved for.

x° + y° + 90° = 180°

x° + y° = 90°

x° + 56° = 90°

x° = 90° - 56°

x° = 34°

The value of the x is 60 km and the value of the y is 70 km.

Given that a man travels x km at 60 km/h and y km at 40 km/h and the total time traveled is 11/4 i.e 2.75 h.

Let's suppose that the time traveled for the x km is t1, time traveled for the y km is t2 and total time is T ,so by using the speed distance formula t1 & t2 will be :

t1 = x/60 and t2 = y/40 ;

T = t1 + t2;

i.e 2.75 = x/60 + y/40 ;

Multiply both sides with 120,

330 = 2x + 3y ............i

Now given that man traveled 5x km at 40 km/h and 3y km at 50 km/h in total time of 11. 7 hours. Similarly the equation for this situation will be :

T = t1 + t2;

x/8 + 3y/50 = 11.7 ;

Multiply both sides with 200, we will get

25x + 12y = 2340 .........ii

Now by simplifying the equation i and ii we will get the value of x and y which are 60 and 70 respectively.

The exponential model of the given data is f(t) = 30.18 × 1.06^t.

Some of the rules of exponents are as follows,

The product of two exponents having the same power is equal to the power of their base multiplied.

The product of two exponents having the same base is equal to the sum of the powers of different exponents to the same base.

Given that,

The average price for office space in 2004 is $30.18.

The average price for office space in 2015 is $66.85.

Suppose the average price in 2004 is taken as y₀.

The given situation can be represented in the form of exponential function f(t) = y₀b^t as,

Take t = 0 for 2004

Then,  f(0) = y₀b^0

⇒ f(0) = y₀ = $30.18.

Then, at 2015, t = 12. Substitute the respective values to get,

f(12) = 30.18 × b^12

⇒ 66.85 = 30.18 × b^12

⇒ b^12 = 66.85 / 30.18

⇒ b = 1.06

Thus in exponential form the given situation can be written as,

f(t) =30.18 × 1.06^t

Hence, the given data can be modeled in exponential function as  f(t) =30.18 × 1.06^t.

Probability refers to possibility. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events. The degree to which something is likely to happen is basically what probability means. You will understand the potential outcomes for a random experiment using this fundamental theory of probability, which is also applied to the probability distribution. Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence.

Answer:

density = 1.43 × 10⁻³ g/cm³

Step-by-step explanation:

We are told that oxygen gas of mass 2.23 kg has a volume of 1.56 × 10⁶ cm³, and we are told to find its density in g/cm³.

To do this we have to first convert the mass, which is given in kg, to g:

mass = 2.23 kg = 2.23 kg × 1000 [tex]\mathrm{_\frac{g}{kg}}[/tex]

                          = 2230 g

Next, we can find the density of the gas using the following formula:

[tex]\boxed{density = \frac{mass}{volume}}[/tex]

⇒ density = [tex]\mathrm{\frac{2230 \ g}{1.56 \times 10^{6} \ cm^3}}[/tex]

                 = 1.43 × 10⁻³ g/cm³

Therefore, the density of the oxygen gas is 1.43 × 10⁻³ g/cm³.

The value of x=0.301 at the x the graph of the function have a horizontal tangent.

Given that,

The function is f(x)=eˣ-2x

We have to find the value of x does the graph of the function have a horizontal tangent.

Where the derivative of a function is zero, a graph's horizontal tangent line is a mathematical feature. This is so that the derivative, by definition, can provide the slope of the tangent line. The slope of horizontal lines is zero. As a result, when the derivative is zero, the tangent line is horizontal.

For horizontal tangent line,

f'(x)=0

The differentiation of the function is

eˣ-2=0

eˣ=2

Taking logarithm on both sides.

logeˣ=log2

We know that loge=1

So,
