The percentage of money spent on books to that of cost for last semester is 16%

The cost for last semester was 2000.

The cost books was 320.

The percentage formula = part/whole × 100

Part = 320

Whole = 2000

Equation = 320/2000× 100

For the given parallel lines AB and CD, the measure of the angle of the triangle ∠FAB = 25°.

For the given question;

Line AB || Line CD

From the given diagram,

∠CFD = ∠AFB = 110 (corresponding angles)

Now, in triangle ABF

By the property of triangle; sum of all interior angles of triangle is 180.

Thus,

∠AFB + ∠ABF + ∠FAB = 180°

Put the values;

110° + 45° + ∠FAB = 180°

∠FAB = 180° - 155°

∠FAB = 25

Thus, the measure of the angle ∠FAB = 25° in triangle FAB.

The option that results in a graph that shows exponential decay is Option(b) f(x) = 3(0.7)ˣ.

According to the question, we have to determine the function that results in a graph that shows exponential decay.

The function will show an exponential decay if the value of b was less than 1 and greater than 0.

As we can notice in the second option, f(x) = 3(0.7)ˣ, where b is equal to 0.7 which is less than one.

So, f(x) = 3(0.7)ˣ shows exponential decay.

The equation of the line in the slope-intercept form is y = -1/4x + 9

From the question, we are to determine the equation of the line that passes through the given points.

The given points are (-4, 8) and (4, 6)

Using the formula,

(y - y₁)/(x - x₁) = (y₂ - y₁)/(x₂ - x₁)

x₁ = -4

y₁ = 8

x₂ = 4

y₂ = 6

Thus,

(y - 8)/(x - -4) = (6 - 8)/(4 - -4)

(y - 8)/(x + 4) = -2 / (4 + 4)

(y - 8)/(x + 4) = -2 / 8

(y - 8)/(x + 4) = -1/4

4(y - 8) = -1(x + 4)

4(y - 8) = -x + 4

y - 8 = -1/4x + 1

y = -1/4x + 1 + 8

y = -1/4x + 9

Therefore,

The equation is y = -1/4x + 9

Smallest number of gift boxes Katy can fill is 56

What is LCM?

Suppose a and b are two numbers. LCM of a and b is the lowest common multiple of a and b. LCM of a and b is the lowest number that is divisible by both a and b.

Here,

Katy buys toys in bags of 8.

Katy buys keyrings in bags of 14.

Each gift box will contain one toy and one keyring.

Number of gift boxes Katy can fill has to be a common multiple of 8 and 14

Smallest number of gift boxes Katy can fill is the least common multiple of 8 and 14

Now,

8 = 2 x 2 x 2

14 = 2 x 7

LCM of 8 and 14 = 2 x 2 x 2 x 7

                           = 56

Alternate angles are angles that occur on opposite sides of the transversal line and have the same size.

Both are obtuse angles and are on the opposite side of the transversal line

Answer:

∠KLC is the alternate angle of ∠BKL

Step-by-step explanation:

Alternate angles are angles that are opposite of one another and on two different parallel lines created by an intersecting line (also known as a transverse line).

In this case, the parallel lines are lines A↔B and C↔D, and the transverse line is M↔N. Therefore, the alternate angle from ∠BKL is ∠KLC.

The equation intercept at (2,3) in the graph given in the question.

Given two equations are ,

3 x - y = 3

-3 x - y = -9

to solve the equations, substract both equations ,

(3 x - y = 3) - (-3x -y = -9)

we get,  6x =12

              x = 2

by substituting value of x in any of the equation we get ,

3 x 2 -y =3

6 -y =3

-y = -3

y = 3

so x = 2 , y = 3

the points on the graph is (2,3)

Both equations are in slope intercept form.

The composite result function of f( g(-2) ) in the given functions f( x ) = x² + 3x and g( x ) = 2x - 1 is 10.

A function is simply a relationship that maps one input to one output..

Given the data in the question;

First, set up the composite result function f( g(x) )

f( x ) = x² + 3x

f( g(x) ) = f( 2x - 1 ) = ( 2x - 1 )² + 3( 2x - 1 )

f( g(x) ) = ( 2x - 1 )² + 3( 2x - 1 )

Simplify

f( g(x) ) = ( 2x - 1 )( 2x - 1 ) + 3( 2x - 1  )

f( g(x) ) = 2x( 2x - 1 ) -1(2x - 1 ) + 3( 2x - 1 )

f( g(x) ) = ( 4x² - 2x  - 2x + 1 ) + 3( 2x - 1 )

f( g(x) ) = ( 4x² - 4x + 1 ) + 6x - 3

f( g(x) ) = 4x² - 4x + 1 - 6x - 3

f( g(x) ) = 4x² - 4x + 6x + 1 - 3

f( g(x) ) = 4x² + 2x - 2

Now,  replace all the occurrence of x with -2 in the function and simplify.

f( g(-2) ) = 4(-2)² + 2(-2) - 2

f( g(-2) ) = 4×4 - 4 - 2

f( g(-2) ) = 16 - 4 - 2

f( g(-2) ) = 10

The composite result function of f( g(-2) ) in the given functions is 10.

The slope of the function as a unit rate for the linear situation. y = [tex]-4\frac{4}{5}[/tex]x + [tex]13\frac{1}{2}[/tex] can be viewed as [tex]-4\frac{4}{5}[/tex] by taking the derivative of the first term of the equation.

The slope m=y/x of a straight-line y=mx+b quantifies the change in y for every unit change in x. This can also be interpreted as a kind of measure of "sensitivity''.

Finding the slope of a function is like finding the rate at which the value of y (the dependent variable) changes in relation to x is what this method entails (independent variable).

To find the slope of a line that is given with the equation of the line, first you have to write the equation of the line in a slope-intercept form.

Then use inverse operations in order to solve for y so that it is written as y=mx+b. Thereafter you can easily spot the slope since the slope is the coefficient of the x variable, or in other words, the number in front of x.

The value of x is 6 and the measure of angle LJK is 27°.

According to the triangle's "angle sum property," a triangle's interior angles add up to 180°.

We have the measure of the following angles,

m∠JKL = ( 3x - 16 )°

m∠LJK = ( 2x + 15 )°

m∠KLM = ( 8x - 19)°

In ΔJKL, JL is extended through point L to point M.

At point L, the measure of angle JLK will be as,

m∠KLM + m∠JLK = 180°

m∠JLK = 180° - m∠KLM

m∠JLK = 180° - ( 8x - 19)°

m∠JLK = ( 199 - 8x )°

Now,

In triangle JKL,

By angle sum property:

m∠JKL + m∠LJK + m∠JLK = 180°

(3x – 16)° + (2x + 15)° + ( 199 - 8x )° = 180°

- 3x + 198 = 180

- 3x = - 18

x = 6°

Therefore,

m∠LJK = ( 2x + 15 )°

m∠LJK = ( 2(6) + 15 )°

m∠LJK = ( 12 + 15 )°

m∠LJK = 27°

The measure of angle LJK is 27°.

we sadly need to do all the multiplications for the whole polynomial in standard form.

the other 3 things we get out of the given form :

we multiply 3 terms, each in x. the result will be x³.

so, we have the 3rd degree.

the leading coefficient is 1, as for the x³ term we get x×x×x = x³. no other number is involved.

the constant term is the extreme on the other end. it is 4×2×1 = 8.

so, now for the full multiplications, that should also show you, why I could make the conclusions above.

(x+4)(x-2)(x+1)

we do this by multiplying first 2 terms with each other, and then we multiply that result by the third term.

remember, we need to multiply every item of one term with every item in the other term.

(x+4)(x-2) = x² -2x + 4x - 8 = x² + 2x - 8

now

(x² + 2x - 8)(x+1) = x³ + x² + 2x² + 2x - 8x - 8 =

= x³ + 3x² - 6x - 8

so, that is already the standard form

f(x) = x³ + 3x² - 6x - 8

The table with the situations that represent or not proportional relationships of distance and time is given at the end of the answer.

A situation represents a proportional relationship if the output variable y in the y-axis is written as a product of the input variable x in the x-axis and the constant of proportionality k, as follows:

y = kx.

One example, in the context of this problem, is the relation between velocity, distance and time, as velocity is distance divided by time, hence:

v = d/t.

The relation between distance and time is given as follows:

distance = velocity x time

distance = v x t.

Hence it will only be proportional if the velocity is constant, that is, if the acceleration is of zero.

Examples of non-proportional situations in the context of this problem are:
