Step-by-step explanation:

Damian earn $43 on friday if he works for 2. 75 hours and is obtained by putting value of time in function f(x).

since the function f(x) = 12x+10 is the function which models the amount Damain earns on each day working x hours, so we have the value of x which is 2.75 for this question so, after putting the value of x in f(x) we will get total earning of Damian on that day.

the function that calculates the total earning of damian on each day is given by the function :

    f(x) = 12x + 10  

 so by working 1 hour we get

   f(1) = 12 * 1 +10 = $22

  it is given that on firday damain works 2.75 hours so we have to find   f(2.75)

f(2.75) = 12 * 2. 75 +10 = 33 +10

so f(2.75) = $43 which is the earning of damian on friday

y+1=6/11(x+4) is the equation in point-slope form of the line that passes through the points (7, 5) and (−4, −1).

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The given two points are  (7, 5) and (−4, −1)

m=-1-5/-4-7

=-6/-11

=6/11

The point slope intercept form is y- y₁=m(x-x₁) through (-4,-1)

y-(-1)=6/11(x-(-4))

y+1=6/11(x+4)

Hence, y+1=6/11(x+4) is the equation in point-slope form of the line that passes through the points (7, 5) and (−4, −1).

The probability is 0.0132.

Here we have mean and standard deviations for air samples from large cities.

According to large samples, the law sample average calculated from large samples is approximately equal to the population average.  

As here sample is taken from a large city, the sample is considered a large sample. Hence mean is approximately equal to the population mean. Also, it is considered a random sample is representative of the population and the sample standard deviation is approximate to the population standard deviation. Hence we can say that carbon monoxide concentrations in air samples from this city are normally distributed.

So here we have

μ = 12

σ = 9 , n = 100

Hence here we need to find,

= p (x > 14)

= p((x-μ /(σ/√n)) > 14-12/9/√100)

Answer:

  a = 80°

Step-by-step explanation:

In order to solve this figure, we need to find a useful relationship between the various angles. We can use the straight angle at the upper left vertex of the equilateral triangle.

__

The sum of angles there is ...

  a + 60° +(a/2) = 180°

Additional comment

All triangles are isosceles, because they all have 2 (or more) sides the same length. That means the base angles are half the supplement of the a.pex angle. Of course, adjacent vertices of a rhombus have supplementary angles.

The solution of the system of equations f(x) = 2^x + 1 and g(x) = 3^x is x = 1

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

The area of the square LMNP is 50 square units

The circumference of the circle is given as:

C = 10π

Circumference is calculated as:

C = 2πr

So, we have:

2πr = 10π

Divide by 2π

r = 5

This represents the length OM

The length PM is calculated as:

PM = 2 * OM

This gives

PM = 2 * 5

PM = 10

The length (PN) of the square is then calculated as:

PM = PN√2

This gives

10 = PN√2

Square both sides

100 = PN^2 * 2

Divide by 2

On solving the provided question, we can say that - linear function is \(y = 0.25x - 0.5.\)

Two distinct but related concepts are referred to as linear functions in mathematics. A polynomial function of degree 0 or 1 is a linear function in calculus and related subjects if its graph is a straight line. Any function that depicts a straight line on a coordinate plane is said to be linear. A linear function, such as y = 3x - 2 in the coordinate plane, indicates a straight line. f(x) = 3x - 2 can be used to represent the function since f(x) can be linked to y.

slope of this line:

\(\frac{3.5 - 2.5}{16 - 12} = 0.25\\\)

We can now determine the y-intercept. Pick a spot at random first:

1/5 x 70 = 14
70 - 14 = 56
5/7 x 56 = 40
56 - 40 = 16

Answer:

16

Step-by-step explanation:

Yesterday, the bookstore sold 1/5 of the 70 copies, which is 70 * 1/5 = 14 copies.

After selling 14 copies, the bookstore was left with 70 - 14 = 56 copies.

Today, the bookstore sold 5/7 of what remained, which is 5/7 * 56 = 40 copies.

So, the bookstore has 56 - 40 = 16 copies left.

An influential point is one that has a significant effect on the slope of the regression line, and an outlier is a point that falls outside of the general pattern of the data.

In this case, the point corresponding to the twelfth car is an outlier because it falls outside of the general pattern of the data, but it is not influential because it does not have a significant effect on the slope of the regression line.

For the reaction,

\(CO(g) + H_2 O(g) = CO_2(g) + H_2(g)\)

Initial concentration:

0.1M , 0.1M , 0 , 0

Let 'x' mole per litre of each of theproduct be formed.

At equilibrium:

(0.1 – x)M , (0.1 – x)M , xM , xM

where x is the amount of Carbon dioxide and Hydrogen, at equilibrium.

Hence, equilibrium constant can be written as,

\(K_c = \frac{x²}{(0.1 – x)²} = 4.24\)

→ x² = 4.24 (0.01 + x² – 0.2x)

→ x² = 0.0424 + 4.24 x² - 0.848x

→ 3.24x² - 0.848x + 0.0424 = 0

a = 3.24, b = -0.848, c = 0.0424

(for quadratic equation ax² + bx+c=0)

\(x = \frac{( - b \: ± \: \sqrt{ {b}^{2} - 4ac) } }{2a} \)

\( = > x = \frac{ - ( - 0.848 \: ± \: \sqrt{( - 0.848)^{2} - 4(3.24)(0.0424) } }{2 \times 3.24} \)

\( = > x = \frac{ - 0.848±0.4118}{6.48} \)

\(x_1 = \frac{0.848 - 0.4118}{6.48} = 0.067\)

\(x_2 = \frac{0.848 + 0.4118}{6.48} = 0.194\)

Here, the value 0.194 should be neglected because it will give concentration of the reactant which is more than initial concentration.

∴ The equilibrium concentrations are :-

\([CO_2] [H_2] = x = 0.067M\)

\([CO] [H_2 O] = 0.1 - 0.067 = 0.033M\)

The equilibrium concentrations of each of the species can be obtained by the use of the ICE table.

Kc refers to the value of the equilibrium constant obtained using the concentrations of the reactants.

Now we have to set up the ICE table as shown below;

             CO + H2O ⇄  CO2 + H2

I             0.1      0.1           0        0

C          - x        - x           +x       +x

E            0.1 - x   0.1 - x     x       x

Kc = [CO2] [H2]/[CO] [H2O]

4.24 = x^2/(0.1 - x)^2

4.24(0.1 - x)^2 = x^2

0.042 - 0.848x + 4.24x^2 = x^2

x^2 -  4.24x^2  + 0.848x - 0.042 = 0

-3.24x^2  + 0.848x - 0.042 = 0

since x can not be greater then the initial concentration, x=0.066M

Final concentration of each specie;

CO = 0.1 M - 0.066M = 0.034 M

H2O = 0.1 M - 0.066M = 0.034 M

CO2 = 0.066M

The solution of this system is (2, 5)

Step-by-step explanation:

Negate each term of the 2nd equation.  We get:

-18x + 6y = -6

 24x - 6y = 18

Combining like terms, we get

 6x = 12, from which we know that x = 2.

Substituting 2 for x in the first equation, we get

-18(2) + 6y = -6, which simplifies to 6y = 30.  Thus, y = 5.

The solution of this system is (2, 5)

The expression that represents the total amount that Julian paid at the register in terms of x is 0.84x.

What is Percentage?

Percentage is a way of expressing a proportion or fraction as a quantity out of 100. The word "percent" means "per hundred," so percentages are often denoted by the symbol %, which represents one part in a hundred.

The first step is to find the discounted price after the 20% discount. This can be found by multiplying the original price by (1 - 0.2), which represents a 20% reduction.

Discounted price = x - 0.2x = 0.8x

Next, a 4% tax is added to the discounted price. This can be found by multiplying the discounted price by (1 + 0.04), which represents a 4% increase.

Total amount paid = (0.8x) * (1 + 0.04) = 0.84x

Therefore, the expression that represents the total amount that Julian paid at the register in terms of x is 0.84x.
