A. The equation is: x = (30/100) * 140

B. The equation is: y = (100/64) * 40

C. The value of x is 160.

A. To write an equation that shows the relationship of 30% of 140 is x, use the formula: x = (percentage/100) * 140

So for this case, we have:

x = (30/100) * 140 = 42

So the equation is: x = (30/100) * 140

B. To write an equation that shows the relationship of 64% of y is 40, use the formula:

y = (100/percentage) * 40

So for this case, we have:

y = (100/64) * 40 = 62.5

So the equation is: y = (100/64) * 40

C. To find the value of x, given that 45% of x is 72, use the formula:

x = (100/percentage) * 72

So for this case, we have:

x = (100/45) * 72 = 160

So the value of x is 160.

What is the percentage?

A number or ratio that can be expressed as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The percentage, therefore, refers to a part per hundred. Per 100 is what the word percent means. It is represented by the symbol “%

Given that the gross income is $101,598

Medical insurance = 7.5 % of $101,598

                              = 7.5% x $101,598

                             =  $7,619.88.

The insurance covered 60% of the medical expenses.

Medical deduction claim = $7,619.88 - (100% - 60%)x $3,800

                                       = $7,619.88 - 40% x $3,800

The solution of the trigonometric function in the interval is x = 0

A trigonometric function is an equation that contains the trigonometric ratios.

Given the trigonometric function secx + tanx = 1, we proceed to solve it as  follows.

secx + tanx = 1

Using the trigonometric identity tan²x + 1 = sec²x

⇒ secx = √(1 + tan²x)

So, substituting this into the equation, we have that

secx + tanx = 1

√(1 + tan²x) + tanx = 1

√(1 + tan²x) = 1 - tanx

Squaring both sides of the equation, we have that

√(1 + tan²x) = 1 - tanx

√(1 + tan²x)² = (1 - tanx)²

1 + tan²x = 1 - 2tanx + tan²x

Substracting 1 from both sides, we have that

1 - 1 + tan²x = 1 - 1 - 2tanx + tan²x

0 + tan²x = 0 - 2tanx + tan²x

tan²x = - 2tanx + tan²x

Substracting tan²x from both sides, we have that

tan²x - tan²x= - 2tanx + tan²x - tan²x

0 = -2tanx + 0

0 = -2tanx

tanx = 0/-2

tanx = 0

taking inverse tan, we have that

x = tan⁻¹0

x = 0

So, the solution is x = 0

Explanation:

We'll use the pythagorean theorem converse.

Consider a triangle with sides a,b,c where c is the longest side.

There are 3 scenarios possible:

The middle or second scenario is probably what you're most familiar with. That's the famous pythagorean theorem without the term "converse" attached to it.

--------------

The two given sides are 8 inches and 10 inches.

Let's say the third side was 5 inches (choice F)

This means we have a triangle with sides a = 5, b = 8, c = 10

Then compute the following:

Since 89 < 100, we see that a^2+b^2 < c^2 is the case. Therefore the triangle with sides 5,8,10 is obtuse.

This will allow us to rule out choice F since we're looking for an acute triangle.

--------------

Now onto choice G.

This time the sides are: a = 6, b = 8, c = 10

Both results (a^2+b^2 and c^2) are the same at 100; so we see that a^2+b^2 = c^2.

Therefore we have a right triangle. We can rule out choice G.

--------------

Now onto choice H.

The triangle now has sides: a = 8, b = 10, c = 12

Since 164 > 144, we see that a^2+b^2 > c^2 is the case. Therefore the triangle with side lengths 8,10,12 is acute.

--------------

For the sake of completeness, let's go over choice J.

We find 164 < 169 which leads to the scenario a^2+b^2 < c^2. The triangle for choice J is obtuse. We can rule out choice J.

You can use something like GeoGebra to help visually verify these results.

The factored form of 26x^5 - 13x is 13x(2x^4 - 1).

What is the greatest common factor?

The greatest common factor (GCF), also known as the greatest common divisor (GCD) or highest common factor (HCF), is a concept in mathematics that refers to the largest positive integer that divides two or more integers without a remainder.

To factor 26x^5 - 13x using the greatest common factor, we need to find the greatest common factor of the two terms.

26x^5 = 213x^5

13x = 13*x

The greatest common factor of the two terms is 13x.

So we can factor it out:

26x^5 - 13x = (13x) (2x^4 - 1)

Hence, the factored form of 26x^5 - 13x is 13x(2x^4 - 1).

c = -1, d = -15

B) The solutions of the equation are 1+ √15 and 1- √15.

A quadratic equation is a type of polynomial equation that has the general form of ax² + bx + c = 0, where x is the variable, a, b, and c are constants, and a is not equal to zero.

a) To write x²  - 2x - 13 in the form (x + c)²  + d, we can complete the square.

First, we add and subtract (2/2)²  = 1 to get:

x²  - 2x - 13 = x²  - 2x - 13 + 1 - 1

Next, we group the terms:

(x²  - 2x) - 14 = (x²  - 2x + 1) - 15

Now, we can see that the left side of the equation is a perfect square trinomial. To complete the square, we add the square of half of the coefficient of the x term, which is (1)² = 1 to both sides:

(x - 1)²  - 15 = 0

So, x² - 2x - 13 = (x - 1)²  - 15

c = -1, d = -15

b) Using the answer from part a, we know that x² - 2x - 13 = (x - 1)² - 15

=0

so (x-1)² = 15

x-1 = ± √15

x = 1 ± √15

The solutions of the equation are 1+ √15 and 1- √15.

g(x) is the vertical stretch and reflection about the x-axis. Hence option (B) is the correct answer.

Vertical compression by a factor M: g(x) = m*f(x)  (m<1)

m = -1.4

Vertical stretch by a factor m: g(x) = (1/m)*f(x) (|m|>1)

hence given vlaue of x g(x) > f(x)

reflection about x axis : y = -f(x)

So, In the given plot, we can say that g(x) is a reflection of f(x) about the x-axis,

Note that the rule that describes the transformation shown is: (x,y) → (x+7,-y)(Number 2)

A transformation is a broad phrase covering four distinct methods of changing the shape and/or location of a point, line, or geometric figure. The Pre-Image is the original shape of the item, and the Image is the final shape and location of the object after the transformation.

Thus, with regard to the transformation above,

At Point A: The original coordinate of point A was (-6,-6).

The coordinate after the transformation is A'(1,6), which eliminates option 3.

At Point B:

The original coordinate of point B was (-2,4).

After the transformation, we have B'(5,-4), which eliminates option 1 and option 4. It is therefore right to state that (x,y) → (x+7,-y) is the correct representation of the transformation.

The mass of the wine can be found by multiplying the density of the wine (0.8 kg/litre) by the volume of the wine (20 litres). The mass of the wine is 16 kg.

Its density is how much "stuff" can fit into a certain quantity of space. For instance, a block of the more resilient, lighter element gold (Au) will have a higher density than a block of the more substantial element lead (Pb) (Au). Styrofoam blocks are not as dense as bricks. Mass per unit volume serves as its definition.

We use the word "density" to indicate how much space (or "volume") an object or substance occupies in relation to the amount of matter contained therein (its mass). Density can also be defined as the quantity of mass per unit of volume.

mass = density x volume

mass = 0.8 kg/litre x 20 litres

mass = 16 kg

Answer:

$20239.6

Step-by-step explanation:

The amount financed for the car is $25,800 - $8,000 = $17,800.

To find the monthly payment, you can use the formula:

M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1]

where M is the monthly payment, P is the amount financed, i is the monthly interest rate (3.99%/12), and n is the number of payments (60 months).

So,

i = 3.99%/12 = 0.00399

n = 60

M = $17,800 [ 0.00399(1 + 0.00399)^60 ] / [ (1 + 0.00399)^60 – 1]

M ≈ $337.31

So, Michelle will make monthly payments of $337.31 for 60 months.

To find the total amount that Michelle will pay for the car, you can multiply the monthly payment by the number of payments:

$337.31 x 60 = $20239.6

So, the total amount that Michelle will pay for the car is $20239.6

The length of the side XY taken out by using trigonometric formulas is 12.208 cm.

Now we know that ΔWXY is a right-angled triangle. With ∠XWY = 90°

Hence we see that we can use the trigonometric formulas to find the length of XY

Since ∠YWX = 35° with XW being the corresponding side and XY being the hypotenuse we can use the formula

cosx = base/hypotenuse

Now using a scientific calculator we can calculate

cos35 to be 0.81915

or, base/hypotenuse = 0.81915

or, WX/XY = 0.81915

or, 10/XY = 0.81915

or, XY = 10/0.81915

or, XY = 12.208 cm
