A submarine starts its descent at -15 meters.
It dives to -182 meters. How far did the
submarine descend?
Since it started at -15 and went to -182 i subtracting to see how far it descended I ended up with 162, however I'm not sure if subtraction was the write operation in this problem, please correct me : )
Answer:
so we're dealing with negative numbers here so after learning negative numbers you have to add negative15 to -182 Wich is negative 197
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]
Help me please:) ✨✨✨✨✨✨✨✨✨✨
Hello there I think the measure of EBC is 58 degrees.
That's because angles EBC and DBE are complementary. it means that they add up to 90 degrees.
We are given that
DBE=32 degrees.
And we know that angles EBC and DBE add up to 90 degrees.
So we take 90 and subtract the measure of angle DBE (32 degrees)
90-32=58
Hope this helps!
[tex]GraceRosalia[/tex]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.

I just need to find the sum of each Answer and distance
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.
This calculation and explanation describes the concept of adding a negative value, which is equivalent to subtracting a positive value, resulting in a displacement in the specified direction on the number line.

Solving by submitting method:
[tex]\sf \leadsto 5x - 4y = 9 \: \: - - - (i)[/tex]
[tex]\sf \leadsto x - 2y = -3 \: \: - - - (ii)[/tex]
By first equation,
[tex]\sf \leadsto 5x - 4y = 9[/tex]
[tex]\sf \leadsto 5x = 9 + 4y[/tex]
[tex]\sf\leadsto x = \frac{9+4y}{5}\\[/tex]
Now, we can find the original value of y from Eqⁿ (ii).
[tex]\sf \leadsto x - 2y = -3[/tex]
[tex]\sf \leadsto \bigg(\frac{9+4y}{5}\bigg) - 2y = -3\\[/tex]
[tex]\sf \leadsto \frac{9+4y-10y}{5} = -3\\[/tex]
[tex]\sf \leadsto \frac{9-6y}{5}= -3\\[/tex]
[tex]\sf \leadsto 9-6y = -3(5)[/tex]
[tex]\sf \leadsto 9 -6y = - 15[/tex]
[tex]\sf \leadsto -6y = - 15 - 9[/tex]
[tex]\sf \leadsto -6y = -6[/tex]
[tex]\sf \leadsto y = \frac{\cancel-6}{\cancel-6}\\ [/tex]
[tex]\sf \leadsto y = \dfrac{ 6}{ 6} \\[/tex]
[tex]\sf \leadsto y = 1[/tex]
Now, we can find the original value of x , from Eqⁿ (I)
[tex]\sf \leadsto 5x-4y = 9[/tex]
[tex]\sf \leadsto 5x - 4(1) = 9[/tex]
[tex]\sf \leadsto 5x - 1 = 9[/tex]
[tex]\sf \leadsto 5x = 9+1[/tex]
[tex]\sf \leadsto 5x = 10[/tex]
[tex]\sf \leadsto x = \frac{10}{5}\\[/tex]
[tex]\sf \leadsto x = 5[/tex]
Therefore, the values of x and y are 5 and 1 respectively.
#2
Solving by Eliminating method:
[tex]\sf \leadsto 4x + 6y = 12\:\:- - - (i)[/tex]
[tex]\sf \leadsto 6x+9y = 12 \:\: - - -(ii)[/tex]
Step 1: Multiply Eqⁿ (I) by 3 and Eqⁿ (ii) by 2 to make the coefficients of y equal. Then we get the equations.
[tex]\sf \leadsto 12x + 18y = 36\:\: - - - (iii) [/tex]
[tex]\sf \leadsto 12x + 18y = 24\:\:- - - (iv)[/tex]
Step 2: Subtract Eqⁿ (iii) from Eqⁿ (iv) , we get
[tex]\sf \leadsto (12x + 18y)-(12x + 18y) = 36-24[/tex]
[tex]\sf \leadsto 0 =12, Which is a false statement. [/tex]
Therefore, the pair of equations has no solution.

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.
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

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

The vertices are given as:
[tex]\mathbf{P = (-8,6)}[/tex]

[tex]\mathbf{P' = (-8,-2)}[/tex]
The rule of translation 3 units right is:

A bird flies at an altitude of 520 feet. A diver dives to a depth of 50 feet below sea level. What is the difference in their elevations? Show how you arrived at your answer.
Answer:
The answer is 570 feet.
Step-by-step explanation:
First, the bird is 520 feet HIGH.
The diver is 50 feet BELOW sea level, which is also -50.
To find the difference, you would SUBTRACT right?
So 520 - -50 OR 520 + 50 (This is because two negatives make a positive, and you are also subtracting negatives, which in turn means adding).
520 + 50 = 570 - HOPE THIS HELPED!
