Answer:

Hello,

Answer TRUE.

Step-by-step explanation:

a | n is read,  a  divide n.

if a | n => n=a*q

if b | n => b | a*q , since gcd(a,b)=1, b | q ==> b=q*k

n=a*q=a*b*k=(a*b)*k so  a*b | n

1/100 < 0.2 < 1/4 is the correct order of the given numbers arranged from least to greatest.

Given that, 1/100, 1/4 and 0.2 and we have to arrange them from least to greatest. So, basically we have to arrange them in ascending order.

1/100 can be written in decimal form as 0.01

1/4 can be written in the decimal form as 0.25

and 0.2 is already in the decimal form.

Now, we have 0.01, 0.25 and 0.2 and we have to arrange them from least to greatest.

Out of 0.01, 0.25 and 0.2, 0.01 is the smallest and 0.25 is the greatest.

0.01 < 0.2 < 0.25

This is the arrangement of the given number in decimal form.

1/100 < 0.2 < 1/4

This is the correct order of 1/100, 1/4 and 0.2 arranged in ascending order.

Therefore, 1/100 < 0.2 < 1/4 is the required answer.

Algebraic expressions are expressions comprised of variables, terms, factors, coefficients, and constants.

They are also made up of arithmetic operations such as addition, subtraction, multiplication division, etc

From the information given, we have that 'p' represents the cost of each pencil

The equation is represented as;

3p + $5 = $11

collect like terms

3p = $11 - $5

subtract like terms

3p = $6

Make 'p' the subject of formula

Answer:

c=(d-4a)/3

Step-by-step explanation:

d=4a+3c, solve for c

If a bathtub has 8 gallons of water in it and it is draining at a constant rate of 6 gallons every 5 minutes. then the equation for the amount of water in the tub is f(x) =8-1.2x and it will take 6.67 minutes to drain the bathtub

Given,

The total quantity of water in the tub = 8 gallons

The quantity of water draining for every 5 minutes = 6 gallons

The quantity of water draining for every 1 minutes = [tex]\frac{6}{5} =1.2[/tex] gallons

Consider the number of minutes as x

Then the equation for the amount of water in the tub

f(x)= 8 - 1.2x

The number off minutes take to empty the tub = Total quantity of water / Quantity of water draining per minute

=[tex]\frac{8}{1.2}=6.67[/tex] minutes

Hence, if a bathtub has 8 gallons of water in it and it is draining at a constant rate of 6 gallons every 5 minutes. then the equation for the amount of water in the tub is f(x) =8-1.2x and it will take 6.67 minutes to drain the bathtub.

f ° g (x) = f( g(x) )                 (1)

Where x is the input variable of the composite function.

In other words, the input of the function f is the output of the function g.

Now we proceed to find the expressions of the each of the two cases:

Case 1

g ° f (x) = g( f(x) )

g ° f (x) = 4 · (2 · x + 2) - 3

g ° f (x) = 8 · x + 8 - 3

g ° f (x) = 8 · x + 5

Case 2

h ° g (- 3 · x) = h [g (- 3 · x)]

h ° g (- 3 · x) = 3 · [4 · (- 3 · x) - 3]

h ° g (- 3 · x) = 3 · (- 12 · x - 3)

In the question ,

it is given that

the value of the car (P) = $28000

rate of deprecation (r) = 20% per year

time period (t) = 6 years

Substituting the values in the Depreciation formula we get ,

Amount = 28000*( 1 - 20/100 )⁶

= 28000*(80/100)⁶

= 28000*(0.80)⁶

The kind of transformation which converts the graph of f(x)  into the graph of g(x) is vertical shrink .

What is transformation in graph?

A graph transformation is a procedure that modifies an existing graph or graphed equation to create different version of the following graph.

It is given that the functions are :

f(x) = -9(x+6)2 - 3

g(x) = -9(x-4)2 - 3

We know that if we perform transformation that meant the graph of f(x) is transformed into the graph of g(x).

i.e.,

f(x) = -9(x+6)2 - 3

f(x) = -18(x+6) - 3

f(x) = -18x - 128 - 3

f(x) = -18x - 72 - 56 - 3

f(x) = -9(x-4)2 - 3 - 56

f(x) = g(x) - 56

or g(x) =  f(x) + (-56)

So , as we are adding f(x), this suggests that the transformation is one of the vertical shrink type.

Therefore, the kind of transformation which converts the graph of f(x)  into the graph of g(x) is vertical shrink .
