The graph has no vertical asymptote
===========================================================
Explanation:
Let's simplify the function by factoring each piece.
[tex]f(x) = \frac{x^2-64}{8x-64}\\\\f(x) = \frac{(x-8)(x+8)}{8x-64}\\\\f(x) = \frac{(x-8)(x+8)}{8(x-8)}\\\\f(x) = \frac{x+8}{8}\\\\[/tex]
In the 2nd step, I used the difference of squares rule to factor the numerator. In the 4th step, the (x-8) terms cancel.
The simplified version doesn't have any variables in the denominator. This indicates the denominator is always 8, and never 0. So it's impossible to divide by zero in this simplified form. Consequently it means this graph has no vertical asymptotes.
However, there is a hole at x = 8 because this input causes a division by zero error in the original non-simplified function. Why? Because the calculator will use PEMDAS to evaluate the expression after replacing every copy of x with 8. It likely won't attempt to simplify like shown in the steps above. This is what causes the hole at x = 8.
The value x = -8 is perfectly fine in either the original function or the simplified one. It doesn't cause the denominator to be zero.
What is the (LCD) 1/6and 1/3
Answer:
The LCD of 1/6 and 1/3 is 6.
Step-by-step explanation:
Rewriting input as fractions if necessary:
1/6, 1/3
For the denominators (6, 3) the least common multiple (LCM) is 6.
LCM(6, 3)
Therefore, the least common denominator (LCD) is 6.
Calculations to rewrite the original inputs as equivalent fractions with the LCD:
1/6 = 1/6 × 1/1 = 1/6
1/3 = 1/3 × 2/2 = 2/6

Find (fog)(0).
f(x)
=
6x
g(x) = 3x + 6
(fog)(0)
Answer:
12
Step-by-step explanation:
The functions f(x) and g(x) are defined as f(x) = 6x and g(x) = 3x + 6
fog(x) = f(g(x))
= f(3x + 6)
= 6(4x +2)
6 x 4x = 24x
6 x 2 = 12
fog(x) = 24x + 12
(fog)(0) where x = 0
= 24(0) + 12
= 0 + 12
(fog)(0) = 12

Write the equation 2x - 4y = 14 in slope-intercept form, and then find the slope and y-intercept.
Answer:
y = 1/2x - 7/2
Slope: 1/2
Y-intercept: (0, -7/2)
Step-by-step explanation:
We know the slope-intercept form of an equation of a line is y = mx + c where slope is m and y-intercept is c.
So, -4y = (-2)x + 14 [divide both sides by -4]
-4/-4 = -2/-4 + 14/-4
y = 1/2 -7/2
Hence the slope = 1/2 and y-intercept = -7/2.

now for the semi circle it is 22/7×2/1×2/1=88/7=12.5÷2=6.2 why is 4/1 turned into 2/1 it is because you are finding area and 4 is the diameter but we need radius so the radius is half of the diameter

Answer:
The answer is negative. Answer choice B
Step-by-step explanation:
Here is the question:
-3^40(5.6/2.1)
According to order of operations, we must do -3^40 first.
Its important to note that -3^40 is different than (-3)^40. In the problem you specified, the ^40 only applies to the 3, not -3. So, first we do 3^40 which is a huge number. And then, we need to add a negative symbol to that huge number. So now we have a massive negative number multiplied by 5.6/2.1, which is obviously positive. Obviously, a negative number multiplied by a positive number is still negative. Therfore, the answer is negative.

A stainless steel patio heater is a square pyramid. The length of one side of the base is 23.4 in. The
slant height of the pyramid is 93.2 in. What is the height of the pyramid?
The height of the pyramid is aboutin.
(Round to one decimal place as needed.)
The height of the square-based pyramid is 91.72 in if the length of one side of the base is 23.4 in.
What is a square pyramid?In geometry, it is defined as the shape having a square base with equal sides length and all the vertex of the square's joints at the top, which is perpendicular to the center of the square.
We have a square pyramid.
Length of the pyramid = 23.4 in
The slant height of the pyramid = 93.2 in
From the figure:
Base length CB = DC = 23.4 in
In a right-angled triangle, BCD
Applying Pythagoras theorem:
DC² + CB² = DB²
23.4² + 23.4² = DB²
DB = 33.092 in
OB = (1/2)DB
OB = (1/2)33.092 = 16.546 in
In the right-angle triangle AOB, again applying Pythagoras theorem:
AO² + OB² = AB²
h² + 16.546² = 93.2²
AO = h (height of the square pyramid)
AB = slant height = 93.2 in
After calculating, we get:
h = 91.719 ≈ 91.72 in
Thus, the height of the square-based pyramid is 91.72 in if the length of one side of the base is 23.4 in.

If f(x) = x³ +7x²-x and g(x)=x²-3, What is the degree of g(f(x))?

Answer:
c) 6
Step-by-step explanation:
Given :
⇒ f(x) = x³ + 7x² - x
⇒ g(x) = x² - 3
===============================================================
Finding the degree of g(f(x)) :
⇒ Degree of f(x) = 3
⇒ Degree of g(x) = 2
⇒ Therefore, degree of g(f(x)) = degree of f(x) × degree of g(x)
⇒ Degree of g(f(x)) = 3 × 2
⇒ Degree of g(f(x)) = 6

For the function f(x) = 3x + 7, find the following:

c) f(x) = 8
b) f(-3) =
d) f(x) = 10
Answer:
a) 13
b) 1/3
c) -2
d) 1
Step-by-step explanation:
This is quite simple if you look at it from a different perspective. Imagine that when it says "f(2)" That you are plugging the number 2 in for every x on the right side of the equation:
For example:
f(x) = 3x + 7
f(2) = 3(2) + 7
f(2) = 6 + 7
f(2) = 13
________
f(-3) = 3x + 7
f(-3) = 3(-3) + 7
f(-3) = -9 + 7
f(-3) = 7 - 9 (This is just for those that hate negative values. You can rearrange the values as long as their sign is the same when you do move them. Ex: -14 + 6 - 4 + 9 == 9 + 6 - 14 - 4. I hope that makes sense.
f(-3) = -2
The other way is quite simple as well, if you look at it from a different perspective. Imagine that when it says "f(x) = 8" that you are changing the f(x) to the number 8:
For example:
f(x) = 8
f(x) = 3x + 7
8 = 3x + 7
8 - 7 = 3x
1 = 3x
x = 1/3
f(x)= 10
f(x) = 3x + 7
10 = 3x + 7
10 - 7 = 3x
3 = 3x
3/3 = x
1 = x

35. the set, s consists of 900,000,000 whole numbers, each being the same number of digits long. howmany digits long is a number from s? (hint: use the fact that a whole number cannot start with the digit 0.)
Answer:
9 digit longLet the number of digits be n and the number of elements in set be s.
When n = 1The set contains 1-digit numbers, 1 through 9,The set consists of 10 - 1 = 9 numbers.When n = 2The set contains 2-digit numbers, 10 through 99,The set contains 100 - 10 = 90 numbers.When n = 3The set contains 3-digit numbers, 100 through 999,The set contains 1000 - 100 = 900 numbers.The pattern we see helps us determine the relationship between s and n as follows.
When set contains n-digit numbers, the set contains:
s = 10ⁿ - 10ⁿ⁻¹ = 10ⁿ⁻¹(10 - 1) = 9*10ⁿ⁻¹ elementsWe have s known, substitute it into equation above and solve for n:
900000000 = 9*10ⁿ¹100000000 = 10ⁿ⁻¹10⁸ = 10ⁿ⁻¹n - 1 = 8n = 9The numbers in the set s are 9-digit long.
