What is transformation function and how to write new equation from transformation function? A transformation function is a mathematical function used to transform a set of data points from one coordinate system to another. The transformation function takes the form of an equation that expresses a relation between two variables. It is commonly used in sciences such as physics and engineering to convert data from one coordinate system to another.For example, if one measure the position of an object in Cartesian coordinates (x,y), the transformation function allows one to express the position of the same object in polar coordinates (r,θ). This can be written as: r = sqrt(x2 + y2); θ = arctan(y/x)To write a new equation from a transformation function, one must first determine the desired coordinate system. Then, one can use the transformation function to find the relation between the two variables in the given coordinate system. For example, if one wants to express the position of an object in Cartesian coordinates from polar coordinates, the equation would take the form: x = r*cos(θ) ;    y = r*sin(θ)This equation expresses the relation between the two variables in Cartesian coordinates.

Harrison’s Loan Stars loaned Nicole $800 that she needed for an unexpected car repair. She must repay the loan in 10 days. The interest is $200. What is the APR for this loan, to the nearest percent?

Answers

Answer:

APR stands for Annual Percentage Rate, which is the interest charged on a loan expressed as a yearly rate. In this case, we are given the interest rate for a loan over 10 days.

To calculate the APR, we need to determine the annualized interest rate, which is the interest rate multiplied by the number of times the interest is compounded per year.

We know that the interest on the loan is $200. The loan amount is $800 and the loan period is 10 days.

First we need to calculate the daily interest rate:

Interest/Loan amount = 200/800 = 0.25

To find the annualized interest rate, we need to multiply the daily interest rate by the number of days in a year:

0.25* 365 = 91.25%

To the nearest percent the APR for this loan is 91%

Answers

1335.88 miles² out of 9,542 miles² is reserved for animal preservation in the national park.

What is area?

The idea of area is essential to contemporary mathematics. A two-dimensional shape, figure, or planar lamina in a plane will occupy a specific amount of space, which is denoted by the area.

The area can be simply defined as the volume of cloth, or other material with the specified thickness, required to construct a model of the shape, or as the volume of paint required to completely cover the surface of the shape in a single layer, or "coat," of paint.

It is a two-dimensional illustration of the length of a curve or the volume of a solid, where length is a one-dimensional concept and volume is a closely related concept that exists in three dimensions.

Area of national park = 9,542 miles²

14% of the area of the park is reserved for animal preservation

= 9542 × 14

= 9542 × 14/100

= 9542 × 0.14

=  1335.88 miles²

Thus, 1335.88 miles² out of 9,542 miles² is reserved for animal preservation in the national park.

f (x) = tan(2x – π)

g(x) = tan(x – π)

h of x equals tangent of the quantity x minus pi over 2 end quantity

j of x equals tangent of the quantity x over 2 minus pi end quantity

Answers

Answer:

A)  f(x) = tan(2x - π)

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{8.3cm}\underline{Standard form of a tangent function}\\\\$f(x)=A \tan(B(x+C))+D$\\\\where:\\\\\phantom{ww}$\bullet$ $A=$ vertical stretch\\ \\\phantom{ww}$\bullet$ $\dfrac{\pi}{|B|}=$ period\\\\\phantom{ww}$\bullet$ $C=$ horizontal shift (positive is to the left)\\\\\phantom{ww}$\bullet$ $D=$ vertical shift\\\end{minipage}}[/tex]

The parent tangent function is:

[tex]f(x)=\tan(x)[/tex]

The period of the parent tangent function is π.

A tangent function is discontinuous when cos(x) = 0, so it has vertical asymptotes whenever cos(x) = 0.

Therefore, the parent tangent function has vertical asymptotes at:

[tex]x=\dfrac{\pi}{2}+\pi n[/tex]

and so its domain is:

[tex]\left\{ x \in \mathbb{R} \;| \;x \neq \dfrac{\pi}{2}+\pi n\right\}[/tex]

If the domain of the given tangent function is:

[tex]\left\{ x \in \mathbb{R} \;| \;x \neq \dfrac{\pi}{4}+\dfrac{\pi}{2}n\right\}[/tex]

then its vertical asymptotes are when:

[tex]x =\dfrac{\pi}{4}+\dfrac{\pi}{2}n[/tex]

Therefore, its period is π/2.

[tex]\implies \dfrac{\pi}{|B|}=\dfrac{\pi}{2}[/tex]

[tex]\implies B=2[/tex]

And it has been horizontally shifted by π/2:

[tex]\implies f(x)=\tan\left(2\left(x-\dfrac{\pi}{2}\right)\right)[/tex]

[tex]\implies f(x)=\tan\left(2x-\pi\right)[/tex]

Function g(x)

There are 108 major sources of pollen in state A. These pollen sources are categorized as grasses, weeds, and treesIf the number of weeds is 7 less than thrice the number of grasses, and the number of trees is 3 more than thrice the number of grasses, find the number of grasses, weeds, and trees that are major pollen sources.

Answers

There are 51 trees, 41 weeds, and 16 grasses that are significant pollen producers.

In the context of beekeeping, the phrase "pollen source" refers to flowering plants that provide pollen to bees and other insects. Bees gather pollen to use as a source of protein for their young.

G, W, and T should stand for the number of grasses, weeds, and trees that serve as significant pollen sources.

According to information provided, state A is home to 80 significant sources of pollen. This data can be represented as follows in an equation:

G + W + T = 108......(1)

According to what is said, there are 7 times as many weeds as there are grasses. This data can be represented as follows in an equation:

W = 3G - 7......(2)

We are also informed that there are three times as many trees as there are grasses. This data can be represented as follows in an equation:

T = 3G + 3

We are also informed that there are three times as many trees as there are grasses. This data can be represented as follows in an equation:

G + W + T = 108

G + 3G - 7 + 3G + 3 = 108

7G - 4 = 108

7G = 112

G= 112/7

G = 16

Therefore, there are 16 grasses that are major pollen sources.

Number of weeds that are major pollen sources:

W = 3G - 7  = 3(16) - 7  = 48 - 7 = 41

Therefore, there are 41 weeds that are major pollen sources.

Number of trees that are major pollen sources:

T = 3G + 3  = 3(16) + 3  = 48 + 3  = 51

Therefore, there are 51 trees that are major pollen sources.

Answers

The best step to use in getting angle ECA is the exterior angle property which gives us; Angle ECA =  154°

What is the missing angle of the triangle?

In a triangle geometry, we know that the exterior angle is always equal to the sum of the interior opposite angles. This property is referred to as  the exterior angle property. This tells us that any two triangles will be similar if their corresponding angles tend to be congruent and the length of their sides will be proportional.

Now, in this question, we are trying to find the measure of angle ECA which is an exterior angle given by the expression 166 - 6x.

Now, the interior opposite angles are (100x - 59) and (6x + 1). Thus;

Applying the exterior angle property, we will have the first step as;

(100x - 59) + (6x + 1) = 166 - 6x

106x - 58 = 166 - 6x

112x = 166 + 58

112x = 224

x = 224/112

x = 2

Angle ECA = 166 - 6(2) = 154°

Step-by-step explanation:

    To solve, we will isolate the variable, k, by using inverse operations.

   Given:

2/5k + 1/6 = 3/10k + 1/3

   Subtract 1/6 from both sides of the equation:

2/5k = 3/10k + 1/6

   Subtract 3/10k from both sides of the equation:

1/10k = 1/6

   Divide both sides of the equation by (1/10), which is the same as multiplying both sides by 10:

k = 5/3

Answer:

k=5/3

Step-by-step explanation:

2/5k+1/6=3/10k+1/3

Move the 3/10k to the left side with subtraction

1/10k+1/6=1/3

Move the 1/6 to the right with subtraction

1/10k=1/6

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , let the first point be A ( 6 , 6 )

Let the second point be B ( 0 , 2 )

The slope of the line m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( 2 - 6 ) / ( 0 - 6 )

Slope m = -4 / -6

Slope m = 2/3

And , the equation of line is y - y₁ = m ( x - x₁ )

Substituting the values in the equation , we get

y - 6 = 2/3 ( x - 6 )

On simplifying the equation , we get

y - 6 = ( 2/3 )x - 4

Adding 6 on both sides of the equation , we get

In order to determine the cost of a pack of gum, we would assign variables to the cost of a pack of gum and cost of a candy bar respectively, and then translate the given word problem into an algebraic equation as follows:

Let the variable g represent the cost of a pack of gum.Let the variable c represent cost of a candy bar.

Since Lionel bought 4 candy bars and 2 packs of gum at the gas station and spent $9.80, a linear equation which models this situation is;

4c + 2g = 9.80    ......equation 1.

Additionally, two packs of gum cost the same as three candy bars:

What is the radius of a hemisphere with a volume of 839\text{ cm}^3,839 cm
3
, to the nearest tenth of a centimeter?

Answers

The radius of the hemisphere with volume 3839cm³ is 11.9cm

What's is volume?

Volume is defined as the space occupied within the boundaries of an object in three-dimensional space. It is also known as the capacity of the object.The volume of the hemisphere is derived by Archimedes. The volume of a hemisphere = (2/3)πr3 cubic units.

The volume of a hemisphere is given as ⅔πr³

Where r is the radius

V = ⅔×3.14r³

3839 = 2/3× 3.14r³

r³ = (3839× 3)/3.14×2

r³ = 11517/6.28

r³ = 1833.9

r = cube root of 1833.9

r = 11.9cm

Therefore the radius of the hemisphere is 11.9cm

Which of these is a complex number?
A. 9+3√5
B.8/3+ √-7/3
c. 5√-7
D. 2 - 11

Answers

The correct answer is B.We can find by complex number by using complex form.

What is a complex number?

Complex numbers are the numbers that are expressed in the form of a+ib where a and b are real numbers and 'i' is an imaginary number called “iota”. The value of i = (√-1). For example 2+3i is a complex number where 2 is a real number (Re) and 3i is an imaginary number (Im).

Why complex number is not a real number?

Every real number is a complex number when the imaginary part is zero. But remember that every complex number is not a real number. For example we can write 5 as 5+0×(i). Hence Every Real Number is a Complex Number.

Now

A complex number is of the form a+ b(i)

 =8/3 +[tex]\sqrt{-7/3}[/tex]

 =8/3 +[tex]\sqrt{7/3}[/tex] [tex]\sqrt{-1}[/tex]

=8/3+[tex]\sqrt{7/3}[/tex] (i)

The second option is a complex number because it can be rewritten in the form

a + b(i).

The base of a right pyramid is a triangle with base and a height of 17cm. If the volume of the pyramid is 11120 cubic cm, find the slant height of the pyramid

Answers

The height of the triangular pyramid will be 154 cm.

What is a triangular pyramid?

A pyramid with a triangle base is referred to as a triangular pyramid. Vertices are essentially corners in geometry. Both regular and irregular triangular-based pyramids contain four vertices.

Pyramids with triangular bases have six edges, three of which run along the base and three of which rise above the base.

The volume of the triangular pyramid will be,

Volume = 1/2 x Base x h

11120 = 1/2 x ( 17 x 17 /2 ) x h

h = ( 11120 x 2 x 2 ) / ( 17 x 17 )

h = 44480 / 289

b. If the area of the trapezium below is 40%2cm2, find the value of x xcm 6cm 8cm​

Answers

X xcm 6cm 8cm is equal to 10cm if the area of the trapezium underneath is 40%2cm2.

What is the value of x xcm 6cm 8cm​ ?

Provide A B C D. trapezium the length of the sides excluding the base is 10,

[tex]$$\therefore \mathrm{AD}=\mathrm{DC}=\mathrm{CB}=10 \mathrm{~cm} \text {. }$$[/tex]

Draw a parallel DP & CQ on AB.

Let [tex]$\mathrm{AP}=x \mathrm{~cm}$[/tex]

In symmetry

[tex]$$\mathrm{QB}=x \mathrm{~cm}$$[/tex]

Consider area A of the trapezium. A B C D

[tex]$$\begin{aligned}& \left.A=\frac{1}{2} \text { (Sum of parallel sides }\right) \times(\text { Height }) \\& A=\frac{1}{2}(D C+A B) \times \text { DP } \quad \ldots(1)\end{aligned}$$[/tex]

Therefore, DPCQ creates a rectangle because DP & CQ are perpendicular to A B and C D were parallel to A B.

[tex]$$\therefore \mathrm{PQ}=\mathrm{DC}=10 \mathrm{~cm}$$[/tex]

Thus,

[tex]$$\begin{aligned}A B & =A P+P Q+Q B \\& =x+10+x \\& =2 x+10\end{aligned}$$[/tex]

Use the equation A r e a = h 2 (a + b) to determine a trapezium's area. The distance between a and b, which are two parallel sides, is denoted by the letter h. To put it another way, add the two parallel sides together, divide by 2, and then multiply this number by the separation between the parallel sides. The surface of a shape's surface is measured by its area. The length and width of a rectangle or square must be multiplied to determine their respective areas. A has a perimeter of x by y.
