Go step by step to reduce the radical. √192
Answer: 8√3.
Step-by-step explanation:
First, look for any perfect squares that can fit into 192 snugly.
If we look for factors of 192, we can discover that the largest perfect square that can fit into it is 64 (and 3).
The √ of 64 is 8.
The √ of 3 cannot be simplified any further.
Thus, leaving us with our answer of 8√3.

Let f(x) = tan(x)-2/x. Let g(x) = x^2+8.
What is f(x)*g(y)?
Answer:
Step-by-step explanation:
(x)*g(y)
=(tanx-2/x)*(y²+8)
=y²tanx+8tanx-2y²/x-16/x
The product of two functions f(x)*g(y), when f(x) = tan(x)-2/x and g(x) = x^2+8 is,
[tex]f(x)\times g(y)= y^2\tan(x)+8\tan(x)-\dfrac{2y^2}{x}-\dfrac{16}{x}[/tex]
What is the product of functions?When the two or more than two functions are multiplies together. Then the resultant function is called the product of these functions.
Let suppose there is a function f(x) and another function g(x). Then the product of function can be written as,
[tex]f(x)\times g(x)[/tex]
Let suppose, a function f(x) is
[tex]f(x)= tan(x)-\dfrac{2}{x}[/tex]
Let another function g(x) is,
[tex]g(x)= x^2+8[/tex]
Then g(y), will be,
[tex]g(y)= y^2+8[/tex]
The product of this two function is,
[tex]f(x)\times g(y)= \left(\tan(x)-\dfrac{2}{x}\right)\times(y^2+8)\\f(x)\times g(y)= y^2\tan(x)+8\tan(x)-\dfrac{2y^2}{x}-\dfrac{16}{x}[/tex]
Thus, the product of two functions f(x)*g(y), when f(x) = tan(x)-2/x and g(x) = x^2+8 is,
[tex]f(x)\times g(y)= y^2\tan(x)+8\tan(x)-\dfrac{2y^2}{x}-\dfrac{16}{x}[/tex]

The length of a rectangular garden is 8 feet longer than its width. The garden's perimeter is 208 feet. Find the length of the garden.
Answer:
The Length is 56 feet
Step-by-step explanation:
w + w + 8 + w + 8 + w = 208 (two sides have a width of w and 2 sides have the length of 8 + w)
Combine the w/s and the 8's
4w + 16 = 208 Subtract 16 from both sides of the equation
4w = 192 Divide both sides by 4
w = 48 The width is 48 feet. That means that the length is 8 feet longer or 56 feet.
Check:
48 + 48 + 56 + 56 = 208
208 = 208

John eats 3/8s of a pizza one day, 1/4 the next day. Can he eat half the next day? Use addition or
subtraction to justify your answer
By using addition and subtraction, we get that, John cannot eat half that is 4 / 8 of the pizza the next day.
Let the total pizza be 1.
On the first day, the fraction of pizza that John ate = 3 / 8
On the next day, the fraction of pizza that John ate = 1 / 4
Total pizza that John ate till now will be calculated using addition:
3 / 8 + 1 / 4
3 / 8 + 2 / 8
5 / 8
Now, the pizza that is left will be calculated by subtracting the pizza that he ate from the total pizza that he had.
1 - 5 / 8
8 / 8 - 5 / 8
3 / 8
We can see that the half pizza is not left.
So, he cannot eat half that is 1 / 2 or 4 / 8 pizza the next day.
Therefore, by using addition and subtraction, we get that, John cannot eat half that is 4 / 8 of the pizza the next day.

Concept Check The table represents a linear function f. (a) Find the slope of the graph of y = f(x). (b) Find the y-intercept of the line. (c) Write an equation for this line in slope-intercept form. X -2 -1 0 1 2 3 y -11 -8 -5 -2 1 4
The slope of the graph of y = f(x) is 3
The y-intercept of the line = -5
Equation for the line in slope - intercept form is y = 3x - 5
Given table of linear function is:
x | y
-2 -11
-1 -8
0 -5
1 -2
2 1
3 4
Slope = Change in y values/ Change in x-values
= -8 --11/-1--2 = 3
Also -5 --8/0--1 =3, -2--5/1-0 = 3, 1--2/1-0 = 3, 4-1/3-2 = 3
So the slope is constant and is m = 3.
y-intercept is the y-value corresponding to when x = 0.
Here, when x = 0, y = -5.
So the y-intercept, c = -5
The equation for the linear function in slope-intercept form is,
y = mx + c , where m is the slope and c, the y-intercept of the function.
So here, the slope-intercept form of the function is,

Find the equation of the circle that passes through the points (7, 3) and (11, −1) and has its centre lying on the line 2x + y = 7.
The equation of the circle that passes through the given points and has its center lying on this line 2x + y = 7 is equal to x² + y² - 10x + 6y - 6 = 0.
The equation of a circle.Mathematically, the standard form of the equation of a circle is given by;
(x - h)² + (y - k)² = r²
Where:
h and k represents the coordinates at the center.r represents the radius of a circle.How to determine the equation of this circle?Assuming the center of this circle lies at (h, k), then we have the following expressions that models the distance from the center of the given circle:
(h - 7)² + (k - 3)² = (h - 11)² + (k - (-1))²
(h - 7)² + (k - 3)² = (h - 11)² + (k + 1)²
(h - 7)² - (h - 11)² = (k + 1)² - (k - 3)²
(h - 7 + h - 11)(h - 7 - h + 11) = (k + 1 + k - 3)(k + 1 - k + 3)
(2h - 18)(4) = (2k - 2)(4)
8h - 72 = 8k - 8
8h - 8k = 64
h - k = 8 .......equation 1.
Since (h, k) lies at 2x + y = 7, we have:
2h + k = 7 .......equation 2.
Solving eqn. 1 and eqn. 2 simultaneously, we have:
h - k = 8
2h + k = 7
3h = 15
h = 15/3
h = 5.
For the value of k, we have:
h - k = 8
5 - k = 8
k = 5 - 8
k = -3.
Next, we would determine the radius of this circle:
Radius, r² = (h - x)² + (k - y)²
Radius, r² = (5 - 7)² + (-3 - 3)²
Radius, r² = (-2)² + (-6)²
Radius, r² = 4 + 36
Radius, r = √40.
Now, we can write the equation of this circle:
(x - h)² + (y - k)² = r²
(x - 5)² + (y - (-3))² = 40
(x - 5)² + (y + 3)² = 40.
x² - 5x - 5x + 25 + y² + 3y + 3y + 9 - 40 = 0
x² - 10x + 25 + y² + 6y - 31 = 0
x² - 10x + y² + 6y - 6 = 0
x² + y² - 10x + 6y - 6 = 0.

THRIDS ONE- 29
Answer:
(b) EF = 5
Step-by-step explanation:
Given point F lies on segment EG, you want to find EF when FG = 12 and EG = 17.
Segment additionThe segment addition postulate tells you the whole is the sum of the parts. That is ...
EF +FG = EG
EF +12 = 17 . . . . . substitute given lengths
Subtracting 12 from both sides of the equation, we have ...
EF = 5
