how do the graphs of the function f(x)=(3/2)x and g(x)=(2/3)x compare

Answer:

3216.99

Step-by-step explanation:

A = 4 [tex]\pi[/tex] [tex]r^{2}[/tex]

d = 2r

A =[tex]\pi[/tex] [tex]d^{2}[/tex]

= [tex]\pi[/tex] * 32^2 = 3216.99  

Subtract the cost of the pencils from the total cost. This will be he amount she spent on erasers. Then divide that amount by the cost of each eraser to get the total.

4.25 - 1.75 = 2.50 spent on erasers

2.50 / 0.25 = 10

She bought 10 erasers.

Answer: 42 inch 16:9 television

Step-by-step explanation:

The dimensions of 42 inch 16:9 television are:

Width of the television = 36.6 inches

Height of the television = 20.6 inches

Screen Area of the television = 36.6 x 20.6 = 753.96 sq inches

The dimensions of 32 inch 4:3 television are:

Width of the television = 25.6 nches

Height of the television = 19.2 inches

Screen Area of the television = 25.6 x 19.2 = 491.52 sq inches

Thus 42 inches 16:9 television has 262.44 square inches more screen area.

Hope it helps.

Thanks you :)

The -30 does not matter in this case because it does not affect the slope. So, you can ignore it and simplify the question to 5x-7y=0.

Move the -7y to the right to get 5x=7y. Then, divide by 7 to isolate y to get y=5x/7.

Therefore, the slope is 5/7.  

Final answer:

The slope of the graph of the line 5x - 7y = -30 is 5/7, determined by rewriting the equation in the slope-intercept form and identifying the coefficient of the x term as the slope.

Explanation:

To find the slope of the graph of the line given by the equation 5x - 7y = -30, we need to rewrite the equation in the slope-intercept form, which is y = mx + b, where m is the slope, and b is the y-intercept. Starting with the given equation:

5x - 7y = -30

-7y = -5x - 30

y = (5/7)x + 30/7

From the transformed equation y = (5/7)x + 30/7, we can see that the slope (m) is 5/7. This means that for every one-unit increase in the independent (x) variable, the dependent (y) variable increases by 5/7 units.

Answer:

A. 3/8

Step-by-step explanation:

Step 1. Change the denominators so they are the same value

1/2 x 4 = 4/8

Step 2. Compare

3/8 < 4/8

Answer:

A. [tex]\dfrac{3}{8}[/tex] is smaller than [tex]\dfrac{1}{2}[/tex].

Step-by-step explanation:

The given fraction is [tex]\dfrac{1}{2}[/tex].

To compare two fractions, either numerator or denominator should be equal.

It is required to compare the given fraction with [tex]\dfrac{3}{8}[/tex] and [tex]\dfrac{5}{8}[/tex].

Now, the given fraction can be written as,

[tex]\dfrac{1}{2}\times\dfrac{4}{4}=\dfrac{4}{8}[/tex]

Now, the denominator of the given fraction is equal to that of other fractions.

In the fraction [tex]\dfrac{3}{8}[/tex] , numerator 3 is smaller than that of the given fraction which is 4.

So, the fraction [tex]\dfrac{3}{8}[/tex]  is smaller than [tex]\dfrac{1}{2}[/tex].

In the fraction [tex]\dfrac{5}{8}[/tex] , numerator 4 is larger than that of the given fraction which is 4.

So, the fraction  [tex]\dfrac{5}{8}[/tex] is larger than [tex]\dfrac{1}{2}[/tex].

Therefore, A. [tex]\dfrac{3}{8}[/tex] is smaller than [tex]\dfrac{1}{2}[/tex].

Answer:

$300

Step-by-step explanation:

Let Dave's saving be D and Sam's savings be S

[tex]\frac{D}{S}=\frac{5}{4}\\4D=5S\\\frac{4}{5}D=S[/tex]

So we subtract 40 from each of them and then the ratio becomes 13 is to 10. Hence we can write:

[tex]\frac{D-40}{S-40}=\frac{13}{10}\\10(D-40)=13(S-40)\\10D-400=13S-520\\-400+520=13S-10D\\120=13S-10D[/tex]

Plugging in [tex]\frac{4}{5}D[/tex] into S (as we found earlier), we can solve for D (our answer):

[tex]120=13S-10D\\120=13(\frac{4}{5}D)-10D\\120=\frac{52}{5}D-10D\\120=\frac{2}{5}D\\D=\frac{120}{\frac{2}{5}}=120*\frac{5}{2}=300[/tex]

So, Dave's savings at first, D, is $300.

Answer:

a progression is a summation of quantities based upon a sequence.

Step-by-step explanation:

example of a progression

1,4,7,10,13,16,.........

a1=1

a2=4

a3=7

difference =d=a2-aq=4-1=3

similarly

d=a3-a2=7-4=3

we can clearly see that there is a difference of 3 between two consecutive terms of a progression

on the other hand successive terms of a progression can be obtained by adding a unique value in backward term to get successive term.

hence a progression is   a summation of quantities based upon a sequence

Answer:

A summation of quantities based upon a sequence, and an arrangement of quantities whose positions are based upon the natural numbers

Step-by-step explanation:

It cannot be "Any list of numbers" because a progression only contains natural numbers, meaning no decimals or fractions. It is also not a new discovery in mathematics.  

For this case, we must indicate which of the given functions is not defined for[tex]x = 0[/tex]

By definition, we know that:

[tex]f (x) = \sqrt {x}[/tex] has a domain from 0 to infinity.

Adding or removing numbers to the variable within the root implies a translation of the function vertically or horizontally. For it to be defined, the term within the root must be positive.

Thus, we observe that:

[tex]y = \sqrt {x-2}[/tex] is not defined, the term inside the root is negative when [tex]x = 0[/tex].

While [tex]y = \sqrt {x + 2}[/tex] if it is defined for [tex]x = 0.[/tex]

[tex]f(x)=\sqrt[3]{x}[/tex], your domain is given by all real numbers.

Adding or removing numbers to the variable within the root implies a translation of the function vertically or horizontally. In the same way, its domain will be given by the real numbers, independently of the sign of the term inside the root.

So, we have:

[tex]y = \sqrt [3] {x-2}[/tex] with x = 0: [tex]y = \sqrt [3] {- 2}[/tex] is defined.

[tex]y = \sqrt [3] {x + 2}[/tex]with x = 0: [tex]y = \sqrt [3] {2}[/tex]in the same way is defined.

Answer:

[tex]y = \sqrt {x-2}[/tex]

Option b

The function that are undefined for (x=0) is  [tex]y = \sqrt[3]{x-2}[/tex] and [tex]y = \sqrt{x-2}[/tex] and this can be determined by putting (x=0) in all the given expressions.

Given :

Function 1 - [tex]y = \sqrt[3]{x-2}[/tex]

Function 2 - [tex]y = \sqrt{x-2}[/tex]

Function 3 - [tex]y = \sqrt[3]{x+2}[/tex]

Function 4 - [tex]y = \sqrt{x+2}[/tex]

Evaluate each function at (x = 0) to determine which function is undefined for (x = 0).

Function 1 - [tex]y = \sqrt[3]{x-2}[/tex]

put (x = 0) in above function:

[tex]y = \sqrt[3]{-2}[/tex]

Therefore, it can be concluded that the above function is not defined for (x=0).

Function 2 - [tex]y = \sqrt{x-2}[/tex]

put (x = 0) in above function:

[tex]y = \sqrt{-2}[/tex]

Therefore, it can be concluded that the above function is not defined for (x=0).

Function 3 - [tex]y = \sqrt[3]{x+2}[/tex]

put (x = 0) in above function:

[tex]y = \sqrt[3]{2}[/tex]

Therefore, it can be concluded that the above function is defined for (x=0).

Function 4 - [tex]y = \sqrt{x+2}[/tex]

put (x = 0) in above function:

[tex]y = \sqrt{2}[/tex]

Therefore, it can be concluded that the above function is defined for (x=0).

Answer:

-35%  

Step-by-step explanation:

To solve this equation, the first thing we have to do is to convert percentages to decimals because we are doing mathematical operations with a fraction.

To convert a percentage to a decimal, we just divide by 100. So, 60% equals 0.60, and 25% equals 0.25.

Next, we subtract these values from 1/2.

So, we have the following steps:

1. Calculate 1/2 - 0.60 (which is the decimal equivalent of 60%). This gives us -0.10.

2. Then subtract 0.25 (which is the decimal equivalent of 25%) from the result. So, -0.10 - 0.25 equals -0.35.

Therefore, 1/2 - 60% - 25% equals -0.35.

Answer: The length is 10ft, the width is 7ft.

Step-by-step explanation:

Let L be the length

Let w be the width

The equation for the perimeter is:

2L+2w=34

We also know that L=2w-4

So we can insert L=2w-4 into 2L+2w=34

2(2w-4)+2w=34

4w-8+2w=34

6w=42

w=7

If the width is 7, we can insert it into 2L+2w=34 to find out the length

2L+14=34

2L=20

L=10

The width is 7 ft, the length is 10 ft.

The length and width of the rectangle are 10 feet and 7 feet respectively. This is determined by setting up and solving equations based on the given information about the relationship between the length and width and the perimeter of the rectangle.

Given that the length (L) of the rectangle is 4 less than twice the width (W), we can represent this as:

L = 2W - 4

. We also know that the perimeter (P) of the rectangle is 34 feet. The formula for the perimeter of a rectangle is

P = 2L + 2W

. Substituting L in the perimeter equation gives

P = 2(2W - 4) + 2W = 34

. Simplifying the equation leads to

4W - 8 + 2W = 34

, and then

6W = 42

when you add 8 to both sides. Solving for W gives

W = 7 feet

. Substituting W = 7 into the length equation gives

L = 2(7) - 4 = 10 feet

. Therefore, the width and length of the rectangle are 7 feet and 10 feet respectively.
