Final answer:

After applying a 40% discount to the original $62 price of the shoes and adding an 8% sales tax, the total cost of the pair of shoes is $40.18.

Explanation:

The question involves calculating the total price of a pair of shoes after a discount and adding sales tax. To find the discounted price, we take 40% off the original price of $62. To calculate 40% of $62, we multiply 62 by 0.40 (which is 40% as a decimal), giving us $24.80. We subtract this discount from the original price: $62 - $24.80 = $37.20, which is the discounted price of the shoes.

Next, calculate the sales tax on the discounted price by converting the sales tax rate from a percent to a decimal. The sales tax rate is 8%, which as a decimal is 0.08. Multiply the discounted price by the sales tax rate: $37.20 x 0.08 = $2.976, which we round to $2.98.

Finally, add the sales tax to the discounted price to find the total cost: $37.20 + $2.98 = $40.18. Therefore, the total price of the shoes, including tax, is $40.18.

The given system of equations are solved to obtain x = -2 and y = 3.

The given system of equation can either have a unique solution, more than one solutions or no solution.

On this basis they are divided into two parts consistent and inconsistent.

A consistent system has one or more solutions while for an inconsistent system there are no solutions.

The equations are given as,

7x - 2y = -20              (1)

9x + 4y = -6               (2)

Multiply equation (1) by 2 and then add to (2) to get,

2(7x - 2y) + 9x + 4y = -20 × 2 + (-6)

⇒ 23x = -46

⇒ x = -2

Then, substitute x = -2 in equation (1) to get,

7 × -2 - 2y = -20

⇒ y = 3

Hence, the solution of the given system of equations is given as x = -2 and y = 3.

Answer:

Correct choice is B

Step-by-step explanation:

The quadratic function g(x) has equation [tex]g(x)=ax^2+bx+c.[/tex] Find values of a, b and c:

[tex]g(0)=2=a\cdot 0^2+b\cdot 0+c\Rightarrow c=2.[/tex]

[tex]g(2)=3=a\cdot 2^2+b\cdot 2++2\Rightarrow 4a+2b=1.[/tex]

[tex]g(4)=2=a\cdot 4^2+b\cdot 4+2\Rightarrow 16a+4b=0.[/tex]

From the last equation [tex]b=-4a[/tex] and [tex]4a-8a=1,\\ \\a=-\dfrac{1}{4},\\ \\b=1.[/tex]

The equation of the quadratic function g(x) is

[tex]g(x)=-\dfrac{1}{4}x^2+x+2.[/tex] This quadratic function determines the parabola with vertex at point (3,2). Thus,

1. The maximal value of f(x) is 4 at x=2.

2. The maximal value of g(x) is 3 at x=2.

Thus, the maximal value of f(x) is greater than the maximal value of g(x). So option B is correct.

Answer:

all of the above

Step-by-step explanation:

Every one of these functions is defined for all values of x.

All the provided functions: y = x, y = 2x^2 + x - 3, y = 3x - 4, y = 2, and y = 3 - x^2, have a domain of all real numbers. This means any real value can be input into these functions to get a real output.

The domain of a function is the set of all possible input values (usually represented by x) that will give an output value. In this case, we are asked to identify which of the provided functions have a domain of all real numbers. For the functions given: y = x, y = 2x^2 + x - 3, y = 3x - 4, y = 2, and y = 3 - x^2, all of them have a domain of all real numbers. This is because no matter what value of x you choose, these functions will always provide a valid output of y. In other words, you can input any real number into these functions and get a real number out.

Answer:

Volume of a in z = 876 ounces

Step-by-step explanation:

For z, the ratio of x and y is 3 : 11

x : y = 3 : 11 , which means in 14 parts of solution z : x will be 3 parts and y will be 11 parts

So, in 2520 ounces solution of z ,

[tex]x=\frac{2520*3}{14}=540\\y=\frac{2520*11}{14}=1980[/tex]

Volume of a in z = { Volume of a in x + Volume of b in x }

Therefore,

[tex]Volume \thinspace of \thinspace a\thinspace in\thinspace x = 540\cdot \frac{2}{5} = 216\\Volume \thinspace of \thinspace b \thinspace in \thinspace x = 1980\cdot \frac{1}{3}=660[/tex]

Answer:

Can not be determined.

Step-by-step explanation:

We can easily notice that the limit is x tends to infinity, whereas x is not present in the given function, we are given (1 + 1/n). So we can not evaluate the given limit for x as parameter, we must have some function of x to solve this problem.

Hence, option C is correct i.e. the limit can not be determined.

Answer:

cannot be determined

Step-by-step explanation:

If we have, [tex]\lim_{n \to \infty} {1+\frac{1}{n}}[/tex]

We plug in infinity for n directly

1/∞ =0

So when we plug in infinity for n  then 1/n becomes 0

[tex]\lim_{n \to \infty} {1+\frac{1}{n}}[/tex]

[tex] {1+\frac{1}{infinity}}[/tex]

1+ 0 = 1

In our problem , limit says x-> ∞

there is no x  term inside

[tex]\lim_{x \to \infty} {1+\frac{1}{n}}[/tex]

so we can clearly say limit cannot be determined

Answer:

The density of the  bar of gold is  19.32 grams per cubic centimeter .

Step-by-step explanation:

Formula

[tex]Density = \frac{Mass}{Volume}[/tex]

As given

A bar of gold has a volume of 722 cubic centimeters and weighs 13.949 kilograms.

As 1 kilogram = 1000 gram

Than convert 13.949 kilograms into grams.

13.949 kilograms = 13.949 × 1000 grams

                             = 13949 grams

Mass = 13949 grams

Volume = 722 cubic centimeter

As put in the formula

[tex]Density = \frac{13949}{722}[/tex]

Density = 19.32 grams per cubic centimeter (Approx)

Therefore the density of the  bar of gold is  19.32 grams per cubic centimeter .

Answer:

see explanation

Step-by-step explanation:

since y is inversely proportional to x the equation relating them is

y = [tex]\frac{k}{x}[/tex] ← k is the constant of proportionality

to find k use the given condition when y = 7, x = 9

k = yx = 7 × 9 = 63

y = [tex]\frac{63}{x}[/tex] ← is the equation connecting them

when x = 21, then

y = [tex]\frac{63}{21}[/tex] = 3

The equation connecting y and x is y = 9 + 3x. When x = 21, y = 72.

The equation connecting y and x is given by y = 9 + 3x. In this equation, the constant term, also known as the y-intercept, is 9. The coefficient of x, also known as the slope, is 3. This means that for every increase of 1 in x, y increases by 3.

To calculate the value of y when x = 21, substitute x = 21 into the equation: y = 9 + 3(21) = 9 + 63 = 72. Therefore, when x = 21, y = 72.

l - lenght

w - width

l - w = 5 → l = 5 + w

26 m - perimeter

l + l + w + w = 2l + 2w - perimeter

substitute l = 5 + w:

2(5 + w) + 2w = (2)(5) + (2)(w) + 2w = 10 + 2w + 2w = 10 + 4w

The equation:

10 + 4w = 26     subtract 10 from both sides

4w = 16    divide both sides by 4

w = 6

Answer:

The 13.2 meters from that point on the ocean floor to the wreck.

Step-by-step explanation:

As given

A ship's sonar finds that the angle of depression to a ship wrack on the bottom of the ocean is 12.5°.

If a point on the ocean floor is 60 meters.

Now by using the trigonometric identity.

[tex]tan\theta = \frac{Perpendicular}{Base}[/tex]

As shown in the figure given below.

Perpendicular = CB

Base = AC = 60 meters

[tex]\theta = 12.5^{\circ}[/tex]

Put in the identity

[tex]tan\ 12.5^{\circ} = \frac{CB}{AC}[/tex]

[tex]tan\ 12.5^{\circ} = \frac{CB}{60}[/tex]

[tex]tan\ 12.5^{\circ} = 0.22[/tex]

[tex]tan\ 12.5^{\circ} = 0.22[/tex]

[tex]0.22= \frac{CB}{60}[/tex]

CB = 60 × 0.22

CB = 13.2 meters

Therefore the 13.2 meters from that point on the ocean floor to the wreck.

The distance from the point on the ocean floor directly below the ship to the shipwreck is approximately 13.3 meters.

We will use the tangent function, which relates the angle of depression to the opposite side (the distance from the point directly below the ship to the shipwreck) and the adjacent side (the depth of the ocean at the point directly below the ship).

Given:

The angle of depression [tex]\theta[/tex] is [tex]12.5^o.[/tex]

The depth of the ocean at the point directly below the ship, h, is 60 meters.

We want to find the distance from the point directly below the ship to the shipwreck, which we will call [tex]d.[/tex]

Using the tangent function :  

[tex]\[ \tan(\theta)[/tex] = [tex][\frac{\text{opposite}}{\text{adjacent}}][/tex]

[tex]\[ \tan(12.5^o) = \frac{d}{60} \][/tex]

To find d, we rearrange the equation:  [tex]\[ d = 60 \times \tan(12.5^o) \][/tex]

Now we calculate the tangent of 12.5 and multiply it by 60:[tex]\[ d = 60 \times \tan(12.5^o) \][/tex]

[tex]\[ d \approx 60 \times 0.22169\][/tex]

[tex]\[ d \approx 13.3014 \][/tex]

Therefore, the distance from the point on the ocean floor directly below the ship to the shipwreck is approximately 13.3 meters.
