Some please help, select all the intervals where g is increasing
Answer:
[tex]( - inf, - 3.5) \\ ( - 1, 2.5)[/tex]
These are interval for increasing (doesnt include relative max-min)
Step-by-step explanation:
Increasing means when we input the value of x and we get the increase of y-value.
A bit hard to imagine? You can look at the graph instead. The name already says it all, Increasing Graph. The graph keeps rising and rising till the max and that is increasing.
The decreasing is when the graph decreases to minimum. The graph would face down for decreasing.
Since we only want the increasing. We look at the graph and tell which region does the graph face up and that is the increasing.

Answer:
541.1 square feet
Step-by-step explanation:
A = πr²
1) convert in. to ft because answer is in sq. ft
78 in => 6.5 ft
2) Find radius of entire area
6.5 ft + radius of inner circle
6.5 + 10 = 16.5
3) Calculate area of combined circles
A = π(16.5)²
A = 855.3 sq. ft
4) Find area of inner circle
A = π(10)²
A = 314.2 sq. ft
5) Subtract area of inner circle from combined area
855.3 sq ft - 314.2 sq. ft = 541.1 sq. ft

Given f (x) = 1/5 (6 – x)^2 what is the value of f(16)?
Answer:
20
Step-by-step explanation:
if f(x)=1/5(6-x)^2 when f(16)you will replace x by 16 then solve it like this
f(16)=1/5(6-16)^2
= 1/5(-10)^2
=1/5(100)

Answer:
The value of x is 3
Step-by-step explanation:
Here, we want to find the value of x
to do this, we apply the principle of similar triangles
That would work as follows;
4/x + 5 = 7/(2x + x + 5)
4/x + 5 = 7/3x + 5
4(3x + 5) = 7(x + 5)
12x + 20 = 7x + 35
12x - 7x = 35-20
5x = 15
x = 15/5

3a² - 24ab + 48b² = 3 ( a - 4b )²
Step-by-step explanation:We will start by rewriting the given quadratic polynomial,
3a² - 24ab + 48b²
Taking out the common "3",
=> 3 ( a² - 8ab + 16b² )
Splitting the middle term i.e. " - 8ab " appropriately,
=> 3 ( a² - 4ab - 4ab + 16b² )
=> 3 [ a ( a - 4b ) - 4b ( a + 4b ) ]
=> 3 ( a - 4b ) ( a - 4b )
Hence, option C is correct.
Answer:
[tex]\huge\boxed{\tt{ 3 (a-4b)(a-4b)}}[/tex]
Step-by-step explanation:
[tex]\sf 3a^2-24ab+48b^2\\\\Taking \ 3 \ as \ common\\\\= 3 (a^2-8ab+16b^2)\\\\= 3 [(a)^2 - 2 (a)(4) + (4b)^2]\\\\Using \ Formula \ a^2 - 2ab + b^2 = (a-b)^2\\\\= 3 (a-4b)^2\\\\= 3 (a-4b)(a-4b)\\\\\rule[225]{225}{2}[/tex]

Suppose ADEF is the image of a translation of AABC. If D is at (-6, -2), what translation rule maps 4ABC to ADEF?
Answer: D. T <-9, -2> (ΔABC) = ΔDEF
Step-by-step explanation:
D = A
A (3, 0) --> D (-6, -2)
To get the x-coordinate of D, you add -9 to 3
To get the y-coordinate of D, you add -2 to 0
T <-9, -2> (ΔABC) = ΔDEF

The median's the middle (organize the numbers from least to greatest, then find the number in the middle)
You add (all the numbers), then divide (by how many numbers there are) for the mean
The mode is the one that appears the most (which number do you see more than once?)
The range is the difference between (find the smallest number and the largest number, then subtract the small one from the large one)

What is range?
In statistics, the range of a set of data is the difference between the largest and smallest values. Difference here is specific, the range of a set of data is the result of subtracting the sample maximum and minimum.
According to question, we have to find different range.
The range of data: [tex]52,48,57,47,49,60,59,51[/tex]
[tex]=60-47=13[/tex]
The range of data:[tex]5,9,13,6,4,5,8,12,12,6[/tex]
[tex]=13-4=9[/tex]
The range of data: [tex]97,106,99,97,115,95,108,100[/tex]
[tex]=115-95=20[/tex]
The range of data : [tex]27,13,35,19,71,12,66,47,39[/tex]
[tex]=71-12=59[/tex]
Hence, we can conclude that
The range of data: [tex]52,48,57,47,49,60,59,51[/tex] is [tex]13[/tex]
The range of data:[tex]5,9,13,6,4,5,8,12,12,6[/tex] is [tex]9[/tex]
