O g(x) = x + 6
Answer:
[tex]g(x) = x + 6[/tex]
Step-by-step explanation:
The parent function is given as:
[tex]f(x) = x + 8[/tex]
We want to find a new function that results after shifting f(x), 2 units to the right.
Let that function be g(x), then
[tex]g(x) = f(x - 2)[/tex]
We replace x by x-2 in f(x) to get:
[tex]g(x) = x - 2 + 8[/tex]
When we simplify, we obtain:
[tex]g(x) = x + 6[/tex]
Rewrite the equation below so that it does not have fractions four -4/9 times equals two over three do not use decimals in your answer please help me I’ll give you 10 points
The equation is 36 - 4x = 6.
Solution:
To write the equation without fraction.
[tex]$4-\frac{4}{9} x=\frac{2}{3}[/tex]
[tex]$\frac{4}{1} -\frac{4}{9} x=\frac{2}{3}[/tex]
The denominators must be same to add/subtract the fractions.
LCM of 1, 9 and 3 = 9.
Multiply first term by [tex]\frac{9}{9}[/tex] and [tex]\frac{2}{3}[/tex] by [tex]\frac{3}{3}[/tex] to make the denominator same.
[tex]$\frac{4\times9}{1\times9} -\frac{4}{9} x=\frac{2\times3}{3\times3}[/tex]
[tex]$\frac{36}{9} -\frac{4}{9} x=\frac{6}{9}[/tex]
[tex]$\frac{36-4x}{9} =\frac{6}{9}[/tex]
Multiply by 9 on both sides.
[tex]$\frac{36-4x}{9}\times9 =\frac{6}{9}\times9[/tex]
Both 9 in the numerator and denominator get canceled.
36 - 4x = 6
This term does not have fraction.
Hence the equation is 36 - 4x = 6.

The volume of the smaller room is B. 768 cubic feet.
Step-by-step explanation:
Step 1:
The entire length for both rooms is 20 feet. As the large room has a length of 12 feet, the length of the smaller room is [tex]20-12=[/tex] 18 feet long.
The width of the prism is 12 feet and a height of 8 feet.
The volume of a rectangular prism is determined by multiplying its length, its width, and its height.
The small room's length = 8 feet,
The small room's width = 12 feet, and
The small room's height = 8 feet.
Step 2:
The volume of a rectangular prism [tex]= (l)(w)(h).[/tex]
The volume of the smaller room [tex]= (8)(12)(8)= 768.[/tex]
So the volume of the smaller room is 768 cubic feet which is option B.
hi! i could really use some help....
Answer:
with what
Step-by-step explanation:
the length of a rectangle is four feet longer than the width. the area is 21. find the dimension
The dimensions of the rectangle are: Width = 3 feet, Length = 7 feet.
The formula for Area of rectangle
Area = length x width
Given:
Area of rectangle = 21 square feet.
Let the width of the rectangle is w feet.
According to the given information, the length of the rectangle is four feet longer than the width,
So, length = w + 4 feet.
So, Area of rectangle = length x width
21 = w (w+4)
[tex]\[21 = w^2 + 4w\][/tex]
[tex]\[w^2 + 4w - 21 = 0\][/tex]
Solve this quadratic equation, set it equal to zero:
w² + 7w -3w -21 =0
w(w+7)-3 (w+7)= 0
(w+7)(w-3) =0
Setting each factor equal to zero:
w+ 7 =0
w= -7
or, w - 3 =0
w = 3
So, the length of rectangle is
= 3+ 4
= 7 feet

3 Maddie's little brother spilled ketchup on one of her homework problems.
Assuming that the number under the spill is greater than zero, fill in the bubble
to show what Maddie should be able to tell for sure about the answer, even
though she can't see the other number.
O The answer will be less than 3.
O The answer will be less than the ketchup-covered number.
O The answer will be a fraction.
O The answer will be greater than the ketchup-covered number.
b.Explain your answer. How do you know the statement you chose is true?
Final answer:
Maddie should be able to tell for sure that the answer will be greater than the ketchup-covered number.
Explanation:
Based on the information provided, Maddie should be able to tell for sure that the answer will be greater than the ketchup-covered number. We can make this determination by comparing the known quantity, which is '3', with the fact that the obscured number is greater than zero. As long as the missing number is positive, any amount added to '3' would result in a sum that is larger than '3'.
If the hidden number is greater than zero and we add it to '3', the result must logically be greater than '3'. This concept is grounded in the basic principles of arithmetic, where adding a positive number to another number increases the total. Therefore, regardless of what the ketchup-covered number is, provided it is more than zero, the sum will indeed be larger than the visible number '3'.

Use the Distributive Property to express
24 + 36
Answer:
12(2 + 3)
Step-by-step explanation:
To use the distributive property, we must find a common factor between the two numbers. The greatest common factor or 24 and 36 is 12. Let's just use that. We get:
[tex]12(2+3) = 24+36[/tex]
That's our answer!
Answer:
12 ( 2 + 3 )= + 36
Step-by-step explanation: GCF between 24 and 36 by prime factorization should be:
24 = 2 * 2 * 2 * 3
36 = 2 * 2 * 3 * 3. what they both have in common between the prime factorization of both of the numbers are 2*2*3 which is GCF and equivlent to 12.

x = pi/4
x=pi/2
x=pi
x=3pi/2
x=3pi
Answer:
[tex]x = \frac{\pi}{2} [/tex]
[tex]x = \frac{3\pi}{2} [/tex]
Step-by-step explanation:
The tangent function is
[tex]y = \tan(x) [/tex]
We can rewrite it as:
[tex]y = \frac{ \sin(x) }{ \cos(x) } [/tex]
This graph has vertical asymptotes at where the denominator is zero.
[tex] \cos(x) = 0 \\ \implies \: x = \frac{\pi}{2} \: or \: \frac{3\pi}{2} [/tex]
The correct options are : (b) [tex]\( x = \frac{\pi}{2} \)[/tex] and (d) [tex]\( x = \frac{3\pi}{2} \)[/tex]
The asymptotes of the tangent graph are the vertical lines where the tangent function is undefined. The tangent function, [tex]\(\tan(x)\)[/tex], is undefined where the cosine function is zero, which happens at:
[tex]\[ x = \frac{\pi}{2} + k\pi \quad \text{for integer values of } k \][/tex]
So, let's check each given value to see if it fits this form.
1. [tex]\( x = \frac{\pi}{4} \)[/tex]
[tex]\[ \frac{\pi}{4} \neq \frac{\pi}{2} + k\pi \][/tex]
This is not an asymptote.
2. [tex]\( x = \frac{\pi}{2} \)[/tex]
[tex]\[ \frac{\pi}{2} = \frac{\pi}{2} + 0 \times \pi \][/tex]
This is an asymptote.
3.[tex]\( x = \pi \)[/tex]
[tex]\[ \pi \neq \frac{\pi}{2} + k\pi \][/tex]
This is not an asymptote.
4. [tex]\( x = \frac{3\pi}{2} \)[/tex]
[tex]\[ \frac{3\pi}{2} = \frac{\pi}{2} + \pi \][/tex]
This is an asymptote.
5.[tex]\( x = 3\pi \)[/tex]
[tex]\[ 3\pi \neq \frac{\pi}{2} + k\pi \][/tex]
This is not an asymptote.
The asymptotes of the tangent graph from the given options are:
[tex]\( x = \frac{\pi}{2} \)[/tex]
[tex]\( x = \frac{3\pi}{2} \)[/tex]
The complete Question is
Select all that are asymptotes of the

what is 1735/1000 written as a decimal?
Answer:
[tex]\frac{1735}{1000}[/tex] as a decimal is 1.735.
Step-by-step explanation:
To convert a fraction into a decimal, you first have to put the fraction into simplest form.
1. Simplest form
[tex]\frac{1735}{1000} = \frac{347}{200}\\\[/tex]
To do this you must find a number you can equally divide both numbers by.
That number in this situation, 5.
[tex]1000/5= 200\\1735/5= 347\\1735:1000 = 347:200\\\frac{1735}{1000} =\frac{347}{200}[/tex]
Now you must make this simplest formed fraction into a mixed number.
2. Simplest form into Mixed number
[tex]\frac{347}{200}= 1\frac{147}{200}[/tex]
To do this you see how many times the denominator, the bottom number of the fraction, goes into the numerator, the upper part of the fraction.
Since 200 x 2 = 400 and since 400 > 347 this means...
200 goes into 347, once.
Finally, subtract and divide.
Remember put the whole number in front of the mixed number, before the decimal
3. Subtract, divide, decimalize
[tex]147/200= 0.735\\\\1\frac{147}{200}= 1.735[/tex]

What is the remainder when x^{6}-4x^4+4x^2-10 is divided by x+3?
Answer:
431
Step-by-step explanation:
Let
[tex]p(x) = {x}^{6} - 4 {x}^{4} + 4 {x}^{2} - 10[/tex]
We want to find the remainder when this polynomial is divided by x+3.
We use the remainder theorem.
Which says that, when p(x) is divided by x-a, the remainder is p(a)=R.
Therefore the remainder when p(x) is divided by x+3 is p(-3).
[tex]p( - 3) = {( - 3)}^{6} - 4 { (- 3)}^{4} + 4 {( - 3)}^{2} - 10[/tex]
We evaluate:
[tex]p( - 3) = 729 - 4 (81)+ 4 {( 9)} - 10[/tex]
We multiply to get;
[tex]p( - 3) = 729 - 324+ 36- 10[/tex]
We simplify to get:
[tex]p( - 3) =431[/tex]
Therefore the remainder is 431
Generally, horses are faster than donkeys. A horse can reach speeds of 55 mph (or approximately 88.50 kph). Most donkeys top out at 30 mph over short distances. What is the top speed of most donkeys in kph? Round your answer to two decimal places.
Answer:
48.30 kph
Step-by-step explanation:
55mph - 88.50kph
1mph - 1.61 kph
30 mph - 48.30 kph
Horses can reach speeds of 55 mph (approximately 88.50 kph), while most donkeys top out at 30 mph over short distances.
A conversion factor is a number that is used to multiply or divide one set of units into another. The acceptable factor to an equivalent value must be utilized when a conversion is crucial.
Given that,
Horses can reach speeds of 55 mph (approximately 88.50 kph).
Most donkeys have a top speed of 30 mph over short distances.
Here the top speed of most donkeys is asked.
To convert miles per hour (mph) to kilometers per hour (kph),
Use the conversion factor of 1.60934.
Calculate the top speed of most donkeys in kph:
Given: Top speed of most donkeys = 30 mph
Conversion: 30 x 1.60934
≈ 48.28 kph
Hence, the top speed of most donkeys, rounded to two decimal places, is approximately 48.28 kph.
