Answer:
The total earned after 30 days is 465000.
Step-by-step explanation:
The amount of money that I'll recieve can be modelled as a arithmetic sequence in which the next element is related to the prior by a sum of a rate "q". This sequence can be seen below:
{1000, 2000, 3000, ...}
Where q = 1000. In order sum all the "n" terms on a sequence of this kind we can use the following formula:
Sn = (n/2)*(a1 + an)
And to find the term an, we can use the formula:
an = a0 + (n-1)*r
Where n is the position of the number we want to calculate, in this case 30, a0 is the first number on the sequence and r is the rate between consecutive numbers. So the 30th term is:
a30 = 1000 + (30 -1)*1000
a30 = 1000 + 29*1000
a30 = 1000 + 29000 = 30000
And the total obtained is:
s30 = (30/2)*(1000 + 30000) = (30/2)*(31000)
s30 = 930000/2 = 465000
The total earned after 30 days is 465000.

The student did not properly distribute the 4 to all terms in the parenthesis:
-8n + 4(1 + 5n) = -6n - 14
First, distribute 4 to ALL terms in the parenthesis:
-8n + 4 + 20n = -6n - 14
Next, isolate the variable, n. Add 6n and subtract 4 from both sides:
-8n + 20n (+6n) + 4 (-4) = -6n (+6n) - 14 (-4)
-8n + 20n + 6n = -14 - 4
Simplify. Combine like terms:
(-8n + 20n) + 6n = -18
12n + 6n = -18
18n = -18
Isolate the variable, n. Divide 18 from both sides:
(18n)/18 = (-18)/18
n = (-18)/18
n = -1
n = -1 is your answer.

Answer:
-According to the student's work shown, The student needs to distribute 1 and 5[tex]n[/tex] by 4. So, the mistake was that the student did not distributed the 1 and 5[tex]n[/tex], in which the student only distributed the 1.
-The equation: [tex]8n + 4(1+5n)=-6n-14[/tex]
-Distributed Incorrectly:
[tex]8n + 4+5n=-6n-14[/tex] (only distributed the 1 by the 4)
-Distributed Correctly:
[tex]8n + 4+20n=-6n-14[/tex] (distributed both 1 and 5[tex]n[/tex] by the 4)
-The correct calculation:
[tex]8n + 4(1+5n)=-6n-14[/tex]
[tex]8n + 4+20n=-6n-14[/tex]
[tex]12n+4 = -6n -14[/tex]
[tex]12n + 4+ 6n=-6n+6n-14[/tex]
[tex]18n +4 = -14[/tex]
[tex]18n +4 -4 = -14 -4[/tex]
[tex]18n = -18[/tex]
[tex]\frac{18n}{18}= \frac{-18}{18}[/tex]
[tex]n = -1[/tex]
The correct answer is [tex]n = -1[/tex] .

The number 1729 is the smallest number that can be expressed as the sum of two cubes in two different ways as 1729 = 12^3 + 1^3 = 10^3 + 9^3. Find two other numbers with the same property. Express them as the sum of two cubes.
Answer:
4104 and 13832
Step-by-step explanation:
This type of number is known as the Hardy-Ramanujan Number.
We have that 1729 is the first number where this is found, but there are others. The second number that meets this is:
4104
2 ^ 3 + 16 ^ 3 = 9 ^ 3 + 15 ^ 3
And we also have:
13832
18 ^ 3 + 20 ^ 3 = 2 ^ 3 + 24 ^ 3
That is to say, the numbers 4104 and 13832 comply with this property

The required exponent on x is 4, the exponent on y is 14, and the exponent on z is 4.
What is simplification?Using math and algebraic principles, simplification entails removing pointless variables, factors, or operations from an expression. Getting an expression that is simpler to use, manipulate, or solve is the aim. For example, simplifying an algebraic expression might involve combining like terms, factoring, or using the distributive property.
Here,
To simplify the given expression, we need to use the rules of exponents:
= [(x²y³)⁻¹ / (x⁻²y²z)²]²
= [(1 / x²y³) / (x⁻⁴y⁴z²)]²
= [(1 / x²y³) * (x⁴ / y⁴z²]²
= x⁴ / y¹⁴z⁴
Therefore, the exponent on x is 4, the exponent on y is 14, and the exponent on z is 4.

Carlos has 4/5 of a tank of fuel in his car. He uses 1/10 of a tank per day.
How many days will his fuel last.
Answer:
8 days.
Step-by-step explanation:
To solve this, we will need to divide fractions to find the amount of days his fuel will last. Remember that when dividing fractions, you need to multiply by the reciprocal of the fraction.
We can do this by:
[tex]\frac{4}{5} * \frac{10}{1} = \frac{40}{5} = 8[/tex]
Therefore, his gas will last 8 days.
Answer:
8

About 450 manta rays are seen near lady Elliot island each year if you were to spot one manta ray at random what is the probability that it would be clouseau
Answer:
Probability that if a manta ray is spotted at random, it would be clouseau = Total number of Clouseau spotted each year) ÷(Total number of manta rays seen each year)
Step-by-step explanation:
The information given is not enough to determine the probability.
We need to know, how many Clouseau are seen each year, then we can find the desired probability.
The Parameters:
Total number of manta rays seen each year = 450
Probability that if a manta ray is spotted at random, it would be clouseau,
P = Total number of Clouseau spotted each year, C) ÷(Total number of manta rays seen each year, T)
P = C/T
P = C/450

The solutions of a quadratic equation are 5 and -1. What is the factored form of a related quadratic function?
Answer:
f(x)=(x+1)(x-5)
Step-by-step explanation:
The solutions to a quadratic equation are going to be your x-intercepts, or when y is equal to zero. For y to be zero, all you have to do is have one value equal to zero. When x is 5, (x-5) is equal to zero. When x is -1, (x+1) is equal to zero. This is one example of what your quadratic equation could be.
