Write the following Arithmetic sequence using an Explicit Formula: a1 = 8, an = an-1 -2
Answer:
an = 8 - 2*(n - 1)
Step-by-step explanation:
a1 ; .... ; an-1 ; an
r = an - an-1
r = (an-1 - 2) - an-1
r = an-1 - 2 - an-1
r = -2
So:
an = a1 + r*(n - 1)
an = 8 + (-2)*(n - 1)
an = 8 - 2*(n - 1)
The nth term of the arithmetic sequence using the explicit formula will be [tex]a_{n}[/tex] = 8 - 2(n - 1) thus option (A) is correct.
What is Arithmetic progression?The difference between every two successive terms in a sequence is the same this is known as an arithmetic progression (AP).
The arithmetic progression has wider use in mathematics for example sum of natural numbers.
As per the given,
First term a₁ = 8
[tex]a_{n} =a_{n-1}-2[/tex]
The common difference between the AP will is,
d = [tex]a_{n} -a_{n-1}[/tex]
d = -2
The nth term of an AP is given as a + (n - 1)d
Thus,
[tex]a_{n}[/tex] = 8 + (n - 1)(-2)
[tex]a_{n}[/tex] = 8 - 2(n - 1)
Hence "The nth term of the arithmetic sequence using the explicit formula will be [tex]a_{n}[/tex] = 8 - 2(n - 1)".

Amy works for 36 hours per week for 10 weeks during the summer, making $\$3000$. If she works for 30 weeks during the school year at the same rate of pay and needs to make another $\$3000$, how many hours per week must she work?
Answer:
12 hours
Step-by-step explanation:
$3000 / 36hours / 10weeks = $8.33333333333
$3000 / 30weeks / $8.33333333333 = 12hours
Answer:
12
Step-by-step explanation:
Since she only needs to make the same amount of money, if she works for 3 times as many weeks, she can work 3 times fewer hours per week, meaning she can work 1/6x36= 12 hours per week

infinitely many solutions
Answer:
Option D.
Step-by-step explanation:
The given system of equations is
[tex]5x+2y=8[/tex] ...(1)
[tex]-4(1.25x+0.5y=2)[/tex] ...(2)
On simplifying the second equation, we get
[tex]-5x-2y=-8[/tex]
On dividing by -1, we get
[tex]5x+2y=8[/tex] ...(3)
It is clear that equation (1) and (3) are same equations. It means equation (1) and (2) represent the equivalent equation.
So, the given system of equations has infinitely many solutions.
Therefore, the correct option is D.
Answer:
infinitely many solutions
Step-by-step explanation:
Because if it is at zero zero the equations represent the same line on a graph.
It can't be A because -4 -4 is a point on a graph would intersect there and that means -4-4 is answer to the equation
It cant be B for the same reason as A
It cant be no solution because then the graph lines would be parellel

What is the multiplicative rate of change of the function?

y
0.25
0.125
0.0625
0.03125
O 0.5
O 0.75
Answer:
Every time x increases by 1, y is multiplied by 0.5. That is the multiplicative rate of change.
Step-by-step explanation:
Well, I am not sure whether this is your question, but I kind of arranged the values into a more clear table.
x 1 2 3 4
y 0.25 0.125 0.0625 0.03125
To find the rate of change, you want to find what can be multiplied by the y-value to get another y-value as the x-value increases.
For example, you can see that when x is 1, y is 0.25. When x increases by 1, y is 0.125.
0.125 / 0.25 = 0.5. That means that when x increases by 1, y is multiplied by 0.5. You can check this by multiplying the rest of the values and seeing whether they match.
0.125 * 0.5 = 0.0625
0.0625 * 0.5 = 0.03125
Since the pattern continues, you can be sure that the multiplicative rate of change for y is 0.5.
The multiplicative rate of change of the exponential function is 0.5
From the table, we have the following representations
x 1 2 3 4
y 0.25 0.125 0.0625 0.03125
Divide yn by yn-1, to calculate the multiplicative rate (r) of change of the function
So, we have:
[tex]r = \frac{y_n}{y_{n - 1}}[/tex]
Let n = 2.
So, we have:
[tex]r = \frac{y_2}{y_{2 - 1}}[/tex]
This gives
[tex]r = \frac{y_2}{y_1}[/tex]
Substitute values for y2 and y1
[tex]r = \frac{0.125}{0.25}[/tex]
Divide
[tex]r = 0.5[/tex]
Hence, the multiplicative rate of change of the function is 0.5

In △ABC, AB=BC=29, and AC=42. What is the area of △ABC?
Answer:
420 unit^2.
Step-by-step explanation:
Use the formula area = √(s(s-a)(s-b)(s-c) where s = the semi-perimeter and ab and c are the 3 sides. (it is called Heron's Formula).
s = (29+29+42)/ 2
= 100/2
= 50.
Area = √50(50-29)(50-29(50-42)
= √176400
= 420.
The area of △ABC is 420 square units.
The formula for calculating Heron's formula is expressed as √(s(s-a)(s-b)(s-c)
where:
s = the semi-perimeter and abc are the 3 sides.Get the value of "s"
s = (29+29+42)/ 2
s = 100/2
s = 50.
Get the required area:
Area = √50(50-29)(50-29(50-42)
Area = √176400
Area = 420.
Hence the area of △ABC is 420 square units.

A right rectangular prism has length 9 cm, width 5 cm, and height 3 cm. If the length, width, and height are doubled, what happens to the surface area?
The surface area is multiplied by 8.
The surface area is multiplied by 4.
The surface area is multiplied by 6.
The surface area is doubled.
Answer:
B - The surface area is multiplied by 4.
Step-by-step explanation:
The first step is to figure out the original surface area of the shape using this formula;
A = 2(wl + hl + hw)
Which in this problem, means:
A = 2 (5 × 9) + 2 (3 × 9) + 2 (3 × 5) = 174.
Now, we must figure out the surface area once the measurements are doubled, using the same equation:
A = 2 (10 × 18) + 2 (6 × 18) + 2 (6 × 10) = 696.
If we then take a look back at the original surface area, we can already tell the answer is not D, as 696 is too high to be double 174, considering 150 × 2 is 300, and 24 × 2 is 28.
We can also eliminate option A, as it's clear multiplying 174 by 8 would take us into the thousands, since 8 × 100 is 800, and already over our target.
So we're left with two options - Multiplied by 4, or multiplied by 6.
If we know that multiplying 174 by 8 would take our answer into the thousands, it's also safe to assume multiplying by 6 would do the same, because 6 × 100 is 600, and multiplying 74 by 6 would take us way over target, too.
However, just to be on the safer side, we can divide 696 by 6;
696 ÷ 6 = 116.
Now we have eliminated answer C.
So the answer is B - The surface area is multiplied by 4.
(Confirmation -
696 ÷ 4 = 174
174 × 4 = 696)

Find the enthalpy change per mole of sodium when sodium reacts with water 8 grams of sodium reacts with 227 cm of water, producing a temperature change from 298
Kto 308.4 K The specific heat capacity of water is 4.18 J/K 9.
Answer:
The enthalpy change per mole of sodium when sodium reacts with water is 28.36 kJ
Step-by-step explanation:
The given parameters are;
Mass of sodium = 8 grams = 0.008 kg
Volume of water = 227 cm³ = 0.000227 m³
Initial water temperature, T₁ = 298 K
Final water temperature, T₂ = 308.4 K
Specific heat capacity of water = 4.18 J/(K·g)
Density of water = 1000 kg/m³
Mass of water = 1000×0.000227 = 0.227 kg = 227 g
Heat change, ΔH = m×c×ΔT = m×c×(T₂ - T₁)
ΔH = 227*4.18*(308.4 - 298) = 9868.144 J = 9.868 kJ
Molar mass of sodium = 22.989769 g/mol
Therefore, 8 grams contains;
8/22.989769 = 0.348 moles of Na
Which gives the enthalpy change per 0.348 moles of Na when sodium reacts with water = 9.868 kJ
Therefore, when one mole of Na reacts with water we have;
The enthalpy change per 0.348/0.348 = 1 mole of Na when sodium reacts with water = 9.868 kJ/0.348 = 28,358.3 J = 28.36 kJ.
What is the probability that two randomly chosen players completed the walk in 2.9 hours or more? Show your work.
Answer:
8.08%
Step-by-step explanation:
Suppose several high schools in a city are sponsoring a walk-athon to raise money for a local charity. A certain route is mapped out through the city and each participant finds sponsors to donate money for the walk. If a participant completes the walk under a certain time, extra money will be donated. You are responsible for recording the finishing times for each of the participants. After collecting all of the data, you determine that the finishing times are normally distributed with a mean of 2.6 hours and a standard deviation of 0.3 hour.
Answer:
Given that:
Mean (μ) = 2.6 hours and standard deviation (σ) = 0.3 hour, n = 2
The z score is used in statistics to determine the amount of standard deviation by which the raw score is above or below the mean. It is given by the equation:
[tex]z=\frac{x-\mu}{\sigma}[/tex], where x is the raw score.
If the sample size (n) is taken then the z score is given by:
[tex]z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n} } }[/tex]
Therefore for this problem the z score is:
[tex]z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n} } }=\frac{2.9-2.6}{\frac{0.3}{\sqrt{2} } }=1.41[/tex]
From the normal distribution table, probability that two randomly chosen players completed the walk in 2.9 hours or more = P(x > 2.9) = P(z > 1.41) = 1 - P(z < 1.41) = 1 - 0.9192 = 0.0808 = 8.08%

Answer: The answer is A:
[tex]1.3[/tex] × [tex]10^{7}[/tex]Step-by-step explanation:
2.6 multiplied by 10 to the power 9 over all of 1.3 multiplied by 10 to the power 2 looks like this-
[tex]2.6[/tex] × [tex]10^{9}[/tex] / [tex]1.3[/tex] × [tex]10^{2}[/tex] or [tex]2.6[/tex] × [tex]10^{9}[/tex] ÷ [tex]1.3[/tex] × [tex]10^{2}[/tex]
Basically a fraction means dividing.
Formula example picture:
According to the Quotient Rule, you have to divide two exponents with the same base, and keep the base and subtract the powers.
Back to the Explanation:
Since you have to divide or subtract with the same base,
[tex]10^{9} - 10^{2}[/tex] remember only subtract the exponents with the quotient rule, and subtract in the same order.
so [tex]10^{9} -10^{2} = 10^{7}[/tex]
now lets move on to 2.6 and 1.6, like the exponents we subtract 2.6 and 1.6.
[tex]2.6 -1.3=1.3[/tex]
so the final answer would be [tex]1.3[/tex] × [tex]10^{7}[/tex]
