Answer:
8.9(2)
Step-by-step explanation:
8.9/2 is division.
8.9+2 is addition.
(8.92) is just adding 2 onto 8.9 which extends the number, not multiplies.

Step-by-step explanation:
Consider a hypothetical consumer named Hayden who is shopping for bread and brie. The graph with bread and brie on the axes presents the utility‑maximizing combinations of bread and brie that Hayden chooses when the price of bread is $1.00 per loaf and the price of brie is $4.00 and $6.00 per wheel, respectively. The other graph shows Hayden's demand curve for brie.
The two points and associated values in the graph for bread and brie combinations correspond to points A and B in the graph of the demand curve for brie. What are the specific prices and quantities of brie associated with points A and B on Hayden's demand curve?
The graphical relationship of the demand and price of brie are given in the two graphs
At point A, the price is $4.00 and the quantity demanded is 23.84At point A, the price is $6.00 and the quantity demanded is 7.49Reason:
The given parameters are;
The graphs gives the utility-maximizing combinations of bread and brie chosen by Hayden
The price of the loaf = $1.00
The prices of the brie are $4.00 and $6.00 per wheel
Given that as the price increases from $4.00 to $6.00, the quantity
demanded increases, we have;
When the price is $4.00, the quantity of brie demanded 23.84 brie wheels,
and the quantity of bread demanded is 15.9 bread loaves
When the price increases to $6.00, the quantity of brie demanded
decreases to 7.49 brie wheels, while the quantity of bread demanded
increases to 25.2 loaves
Therefore; we have;
At point A, the price is $4.00 and the quantity demanded is 23.84
At point B, the price is $6.00 and the quantity demanded is 7.49

In the figure below lines m and n are parallel. in the diagram shown, Angle 7 measures 92 degrees. What is the measure of Angle 8?
A. 8 degrees
B. 88 degrees
C. 92 degrees
D. 180 degrees
Answer:
b
Step-by-step explanation:
The sum of angles 7 and 8 is 180, so to find angle 8 you would subtract angle 7 from 180. So:
180 - 92 = 88
The answer is B, 88 degrees.
Answer:
88° is your answer......
Find the measures of the labeled angles.
Answer:
x + 93 = 124
Step-by-step explanation:
4x = x + 93 {Vertically opposite angles are equal}
Subtract 'x' from both sides
4x - x = 93
3x = 93
Divide both sides by 3
x = 93/3
x = 31
x + 93 = 31+ 93 = 124
The random-number generator on calculators randomly generates a number between 0 and 1. The random variable X, the number generated, follows a uniform probability distribution.
(a) Identify the graph of the uniform density function.
(b) What is the probability of generating a number between 0.01 and 0.34?
(c) What is the probability of generating a number greater than 0.95?
Using the uniform distribution, we have that:
a) The graph is sketched at the end of this answer.
b) 0.33 = 33% probability of generating a number between 0.01 and 0.34.
c) 0.05 = 5% probability of generating a number greater than 0.95.
An uniform distribution has two bounds, a and b.
The probability of finding a value between c and d is:
[tex]P(c \leq X \leq d) = \frac{d - c}{b - a}[/tex]
The probability of finding a value above x is:
[tex]P(X > x) = \frac{b - x}{b - a}[/tex]
In this problem, uniformly distributed between 0 and 1, thus [tex]a = 0, b = 1[/tex].
Item b:
[tex]P(0.01 \leq X \leq 0.34) = \frac{0.34 - 0.01}{1 - 0} = 0.33[/tex]
0.33 = 33% probability of generating a number between 0.01 and 0.34.
Item c:
[tex]P(X > 0.95) = \frac{1 - 0.95}{1 - 0} = 0.05[/tex]
0.05 = 5% probability of generating a number greater than 0.95.

4+(−7) is 7 units from 4, in the negative direction (that is, to the left of 4)
4 + (-7) is 7 (seven) units from 4, in the negative Direction.
The result of 4 + (-7) is -3. It represents a movement of 7 units in the negative direction from the starting point of 4.
In this context, "units" refer to a number-line, where positive values are to the right and negative values are to the left. Starting at 4 and moving 7 units to the left brings you to -3.

You buy cauliflower at $18 per pound. One portion of cauliflower requires 6 ounces of cauliflower. How much does the cauliflower for one portion cost?
The cauliflower for one portion cost $6.75.
The first step is to convert pounds to ounces. The unit of conversion of pounds to ounces is 1 pound is equivalent to 16 ounces.
1 pound = 16 ounces
Therefore, 16 ounces of cauliflower costs $18.
The cost of one ounce = 18 / 16 = $1.125
The cost of one portion of cauliflower is:
Cost of one ounce x number of ounces in one portion
$1.125 x $6 = $6.75

Answer:
Step-by-step explanation:
Just make an example
The vertices of a triangle are P(-8, 6), Q(1, -3), and R(-6, -3). Name the image of P after a reflection over y = 2, and
then shifted right 3 units.
Transformation involves changing the location of a shape
The image of P after the transformation is: (-5,-2)
The vertices are given as:
[tex]\mathbf{P = (-8,6)}[/tex]
[tex]\mathbf{Q = (1,-3)}[/tex]
[tex]\mathbf{R = (-6,-3)}[/tex]
The rule of reflection across line y = 2 is:
[tex]\mathbf{(x,y) \to (x,4-y)}[/tex]
So, the image of P, after the reflection is:
[tex]\mathbf{P' = (-8,4-6)}[/tex]
[tex]\mathbf{P' = (-8,-2)}[/tex]
The rule of translation 3 units right is:
[tex]\mathbf{(x,y) \to (x + 3,y)}[/tex]
So, we have:
[tex]\mathbf{P" = (-8 + 3,-2)}[/tex]
[tex]\mathbf{P" = (-5,-2)}[/tex]
Hence, the image of P after the transformation is: (-5,-2)

the ratio of hours to miles on a bicycle is 2 hours to 30 miles at this rate, how many miles can the bicycle travel in 4 hours? *Think about equivalent ratios.
Answer:60 miles.
Step-by-step explanation:
m=number of miles the bicycle can travel in 4 hours.
Set up a ratio of hours over miles.
2/30=4/m. Multiply both sides by m. (2m)/30=4. Multiply both sides by 30. 2m=120. M=60. You could also just realize that you are multiplying the numerator by 2 of the fraction 2/30 to get 4/m, so you would also have to multiply the denominator by 2 so that both of the fractions are equivalent. So then you’d just multiply the bottom by 2 to get the miles the bike travels in 4 hours.

You need to use this equation to find this answer even though I already wrote the answer there for you.
Lim x-> vô cùng ((căn bậc ba 3 (3x^3+3x^2+x-1)) -(căn bậc 3 (3x^3-x^2+1)))
I believe the given limit is
[tex]\displaystyle \lim_{x\to\infty} \bigg(\sqrt[3]{3x^3+3x^2+x-1} - \sqrt[3]{3x^3-x^2+1}\bigg)[/tex]
Let
[tex]a = 3x^3+3x^2+x-1 \text{ and }b = 3x^3-x^2+1[/tex]
Now rewrite the expression as a difference of cubes:
[tex]a^{1/3}-b^{1/3} = \dfrac{\left(a^{1/3}-b^{1/3}\right)\left(a^{2/3}+a^{1/3}b^{1/3}+b^{2/3}\right)}{\left(a^{2/3}+a^{1/3}b^{1/3}+b^{2/3}\right)} \\\\ = \dfrac{a-b}{a^{2/3}+a^{1/3}b^{1/3}+b^{2/3}}[/tex]
Then
[tex]a-b = (3x^3+3x^2+x-1) - (3x^3-x^2+1) \\\\ = 4x^2+x-2[/tex]
The limit is then equivalent to
[tex]\displaystyle \lim_{x\to\infty} \frac{4x^2+x-2}{a^{2/3}+(ab)^{1/3}+b^{2/3}}[/tex]
From each remaining cube root expression, remove the cubic terms:
[tex]a^{2/3} = \left(3x^3+3x^2+x-1\right)^{2/3} \\\\ = \left(x^3\right)^{2/3} \left(3+\dfrac3x+\dfrac1{x^2}-\dfrac1{x^3}\right)^{2/3} \\\\ = x^2 \left(3+\dfrac3x+\dfrac1{x^2}-\dfrac1{x^3}\right)^{2/3}[/tex]
[tex](ab)^{1/3} = \left((3x^3+3x^2+x-1)(3x^3-x^2+1)\right)^{1/3} \\\\ = \left(\left(x^3\right)^{1/3}\right)^2 \left(\left(3+\dfrac3x+\dfrac1{x^2}-\dfrac1x\right)\left(3-\dfrac1x+\dfrac1{x^3}\right)\right)^{1/3} \\\\ = x^2 \left(9+\dfrac6x-\dfrac1{x^3}+\dfrac4{x^4}+\dfrac1{x^5}-\dfrac1{x^6}\right)^{1/3}[/tex]
[tex]b^{2/3} = \left(3x^3-x^2+1\right)^{2/3} \\\\ = \left(x^3\right)^{2/3} \left(3-\dfrac1x+\dfrac1{x^3}\right)^{2/3} \\\\ = x^2 \left(3-\dfrac1x+\dfrac1{x^3}\right)^{2/3}[/tex]
Now that we see each term in the denominator has a factor of x ², we can eliminate it :
[tex]\displaystyle \lim_{x\to\infty} \frac{4x^2+x-2}{a^{2/3}+(ab)^{1/3}+b^{2/3}} \\\\ = \lim_{x\to\infty} \frac{4x^2+x-2}{x^2 \left(\left(3+\dfrac3x+\dfrac1{x^2}-\dfrac1{x^3}\right)^{2/3} + \left(9+\dfrac6x-\dfrac1{x^3}+\dfrac4{x^4}+\dfrac1{x^5}-\dfrac1{x^6}\right)^{1/3} + \left(3-\dfrac1x+\dfrac1{x^3}\right)^{2/3}\right)}[/tex]
[tex]=\displaystyle \lim_{x\to\infty} \frac{4+\dfrac1x-\dfrac2{x^2}}{\left(3+\dfrac3x+\dfrac1{x^2}-\dfrac1{x^3}\right)^{2/3} + \left(9+\dfrac6x-\dfrac1{x^3}+\dfrac4{x^4}+\dfrac1{x^5}-\dfrac1{x^6}\right)^{1/3} + \left(3-\dfrac1x+\dfrac1{x^3}\right)^{2/3}}[/tex]
As x goes to infinity, each of the 1/x ⁿ terms converge to 0, leaving us with the overall limit,
[tex]\displaystyle \frac{4+0-0}{(3+0+0-0)^{2/3} + (9+0-0+0+0-0)^{1/3} + (3-0+0)^{2/3}} \\\\ = \frac{4}{3^{2/3}+(3^2)^{1/3}+3^{2/3}} \\\\ = \frac{4}{3\cdot 3^{2/3}} = \boxed{\frac{4}{3^{5/3}}}[/tex]
