We have two possible solutions.if the value for δs is postive, and the value for δh is negative, thr reaction will be
A positive δS and a negative δH indicate a spontaneous reaction.
The signs of δs and δh are related to the spontaneity of a reaction through the Gibbs free energy equation:
ΔG = ΔH - TΔS
where ΔG is the change in Gibbs free energy, ΔH is the change in enthalpy, T is the temperature in Kelvin, and ΔS is the change in entropy.
For a spontaneous reaction, ΔG must be negative. The sign of ΔG depends on the signs of ΔH and ΔS and the temperature. Specifically, if ΔH is negative (exothermic reaction) and ΔS is positive (increase in disorder), then ΔG will be negative and the reaction will be spontaneous at all temperatures.
If δs is positive and δh is negative, then ΔS is positive and ΔH is negative. This satisfies the conditions for a spontaneous reaction, and therefore the reaction will be spontaneous at all temperatures.
In summary, a positive δS and a negative δH indicate a spontaneous reaction.

Leila has 36 photos of her friends. She puts 6 photo on each page in her scrapbook. How many pages does Leila use?
Let p stand for the number of pages Leila uses. Which equations can be used to solve the problem? Choose ALL the correct answers.
p = 6 x 36
36 = p x 6
p = 36 x 6
p = 36 divided by 6
Answer: b and d (options 2 and 4)
Step-by-step explanation:
36 photos divided amongst ? pages with 6 on each page means that
#1 (p=6*36) is incorrect
#2 (36=p*6) is correct since the number of pages times 6 should equal 36
#3 (p=36*6) is essentially the first option and therefore incorrect
#4 (p=36/6) is correct because 36 pictures divided with 6 pictures on each page will give you the amount of pages
FYI, the amount of pages is 6.

Answer format: (__,__)
Answer:
x = {-8 - √10, -8 + √10} exact answer
x = {-11.16, -4.84} decimal approximation
Step-by-step explanation:
2(x + 8)²+ 9 = 29
Subtract 9 from both sides
2(x + 8)² = 20
Divide both sides by 2
(x + 8)² = 10
Take the square root of both sides
x + 8 = ±√10
Subtract 8 from both sides
x = -8 ± √10
x = {-8 - √10, -8 + √10} exact answer
x = {-11.16, -4.84} decimal approximation
(PLS HURRY!) On Melissa's 6th birthday, she gets a 2000$ CD that earns 6% interest, compounded. If the CD matures on her 14th birthday, how much money will be available?
Using compound interest formula when the CD matures on Melissa's 14th birthday, there will be $3187.69 available.
What is Compound Interest?The interest that is calculated using both the principal and the interest that has accrued during the previous period is called compound interest. It differs from simple interest in that the principal is not taken into account when determining the interest for the subsequent period with simple interest. Compound interest is commonly abbreviated C.I. in mathematics.
Use the formula for compound interest to calculate the amount of money that will be available when the CD matures -
\(A = P(1 + r/n)^(nt)\)
Where A is the amount of money available when the CD matures, P is the initial principal, r is the interest rate, n is the number of times the interest is compounded per year, and t is the time in years.
In this case, the initial principal is $2000, the interest rate is 6%, and the CD will be held for 8 years (from Melissa's 6th to 14th birthday).
It is not given how many times per year the interest is compounded, so assume it is compounded annually.
Using these values in the formula -
\(A = $2000(1 + 0.06/1)^(1*8)A = $2000(1.06)^8A = $3187.69\)
Therefore, the value is obtained as $3187.69.

Abbey Road Motors pays a percent commission to its sales people. They are paid
a percent of the profit the dealership makes on a car. If the profit is under $1,000,
the commission rate is 20%. If the profit is at least $1,000 and less than or equal to
$2,000, the commission rate is 20% of the first $1,000 and 24% of the remainder of
the profit. If the profit is above $2,000, the rate is 20% of the first $1,000 of profit,
24% of the next $1,000 of profit, and 29% of the amount of profit over $2,000. If p
represents the profit, express the commission c(p) algebraically as a split function.
Answer:
c(p) = {0.2 p ⇒ p < 1000
0.24 p - 40 ⇒ 1000 ≤ p ≤ 2000
0.29 p - 140 ⇒ p > 2000}
Step-by-step explanation:
* Lets explain how to solve the problem
- The profit is represented by p
1. If the profit is under $1,000, the commission rate is 20%
∵ The profit is p < 1000
∵ 20% of p = = 0.2 p
∵ c(p) is the function of the commission
∴ c(p) = 0.2 p when p < 1000
2. If the profit is at least $1,000 and less than or equal to $2,000, the
commission rate is 20% of the first $1,000 and 24% of the remainder
of the profit
- At least means greater than or equal
∵ The profit 1000 ≤ p ≤ 2000
- The commission is divided into 20% of first $1000 and 24% of
the reminder
∵ 20% of 1000 = = 200
∵ The remainder of the profit = p - 1000
∵ 24% of the remainder profit =
= 0.24(p - 1000) = 0.24 p - 240
∴ The total commission = 200 + 0.24 p - 240
∴ The total commission = 0.24 p - 40
∴ c(p) = 0.24 p - 40 when 1000 ≤ p ≤ 2000
3. If the profit is above $2,000, the rate is 20% of the first $1,000
of profit, 24% of the next $1,000 of profit, and 29% of the amount
of profit over $2,000
∵ The profit p > 2000
- The commission is divided into 20% of first $1000 and 24% of the
next $1,000 of profit, and 29% of the amount of profit over $2,000
∵ 20% of 1000 = = 200
∵ 24% of 1000 = = 240
- The amount of profit over $2,000 = p - 2000
∵ 29% of the amount of profit over $2,000 =
= 0.29(p - 2000)
= 0.29 p - 580
∴ The total commission = 200 + 240 + 0.29 p - 580
∴ The total commission = 0.29 p - 140
∴ c(p) = 0.29 p - 140 when p > 2000
* The commission function is:
c(p) = {0.2 p ⇒ p < 1000
0.24 p - 40 ⇒ 1000 ≤ p ≤ 2000
0.29 p - 140 ⇒ p > 2000}* Lets explain how to solve the problem

2. If the profit is at least $1,000 and less than or equal to $2,000, the
commission rate is 20% of the first $1,000 and 24% of the remainder
of the profit
- At least means greater than or equal

∵ The remainder of the profit = p - 1000
∵ 24% of the remainder profit =
= 0.24(p - 1000) = 0.24 p - 240
∴ The total commission = 200 + 0.24 p - 240
∴ The total commission = 0.24 p - 40
∴ c(p) = 0.24 p - 40 when 1000 ≤ p ≤ 2000
3. If the profit is above $2,000, the rate is 20% of the first $1,000
of profit, 24% of the next $1,000 of profit, and 29% of the amount

- The commission is divided into 20% of first $1000 and 24% of the
next $1,000 of profit, and 29% of the amount of profit over $2,000
∵ 20% of 1000 = = 200
∵ 24% of 1000 = = 240
- The amount of profit over $2,000 = p - 2000
∵ 29% of the amount of profit over $2,000 =
= 0.29(p - 2000)
= 0.29 p - 580
∴ The total commission = 200 + 240 + 0.29 p - 580
∴ The total commission = 0.29 p - 140
∴ c(p) = 0.29 p - 140 when p > 2000
* The commission function is:
c(p) = {0.2 p ⇒ p < 1000
0.24 p - 40 ⇒ 1000 ≤ p ≤ 2000
0.29 p - 140 ⇒ p > 2000}
4 Now, use the information from the last step to calculate the probability of E, the event of rolling at least one 6. (Round your final answer to three decimal places.) P(E) = 1 – P(E^C)
To calculate the probability of event E, which is rolling at least one 6, we can use the complement rule.
P(E) = 1 - P(E^C)
First, let's calculate P(E^C), the probability of the complement event, which is rolling no 6's in a single roll of the die. Assuming a fair 6-sided die, the probability of not rolling a 6 on a single roll is 5/6.
P(E^C) = 5/6
Now, we can calculate P(E) using the complement rule:
P(E) = 1 - P(E^C)
P(E) = 1 - 5/6
P(E) = 1/6
Therefore, the probability of rolling at least one 6 (event E) is 1/6, or approximately 0.167 (rounded to three decimal places).

a. True
b. False
This statement is - true.
Two angles that lie in the same plane and have a common vertex and a common side but have no common interior points are the meaning of adjacent angles.
A figure in which two rays meet at a common point is called an angle. The common endpoint of two rays that form the angle is called a vertex. Interior points are the points that lie within the arms of the angle produced indefinitely.If the two angles share a common vertex and side, those angles are called adjacent angles. Adjacent angles are categorized as complementary angles and supplementary angles.If the sum of two adjacent angles comes to 90°, those angles are called complementary angles because they complement each other. e.g. 40° and 50° are complementary angles.When the sum of two adjacent angles becomes 180° and the angles form a straight line, those angles are known as supplementary angles. e.g. 120° and 60° are supplementary angles.Read more about adjacent angles:

The measure of the largest angle of a triangle is 10 more than 4 times the measure of the smallest angle. The measure of another angle is
20° more than the smallest angle.
What is the measure of the largest angle of the triangle?
the measure of the largest angle of the triangle is Largest angle = 4x + 10 = 4(25) + 10 = 110 So, the largest angle of the triangle has a measure of 110 degrees.
tLet x be the measure of the smallest angle of the triangle.
According to the problem statement, the measure of the largest angle of the triangle is 10 more than 4 times the measure of the smallest angle. Therefore, we can write:
Largest angle = 4x + 10
The measure of another angle is 20° more than the smallest angle. Therefore, we can write:
Other angle = x + 20
Since the sum of the measures of the angles in a triangle is always 180 degrees, we can write an equation based on this fact:
Smallest angle + Largest angle + Other angle = 180
Substituting the expressions we have for the largest angle and the other angle, we get:
x + (4x + 10) + (x + 20) = 180
Simplifying the expression, we get:
6x + 30 = 180
Subtracting 30 from both sides, we get:
6x = 150
Dividing both sides by 6, we get:
x = 25
Therefore, the measure of the largest angle of the triangle is:
Largest angle = 4x + 10 = 4(25) + 10 = 110
So, the largest angle of the triangle has a measure of 110 degrees.

A store offers a loan for $900 to buy a computer. The terms of the loan
are for 9% simple interest and equal monthly payments for three years.
What is the monthly payment?
O $1143
O $700
o $31.75
o $92.50
Answer:
(c) $31.75
Step-by-step explanation:
First of all, you need to use some number sense to estimate an answer.
If the $900 loan had no interest, 1/3 of it would be paid off in each of the 3 years, or about $300 each year. You will be making 12 monthly payments each year, so the amount of principal being paid with each payment is $300/12 = $25. Any answer much above this amount will not make sense, so you can immediately reject all choices except $31.75.
__
The simple interest on the loan is ...
I = Prt = $900×0.09×3 = $243
That, too, is divided among the 36 payments, so adds ...
$243/36 = $6.75 to each of the $25 payments we calculated above.
The monthly payment is ...
$25 +6.75 = $31.75

The volume of a solid is \(\frac{26}{3} \pi\).
Given
The given curves about the specified line. y = x + 1, y = 0, x = 0, x = 2; about the x-axis
Curve is y = x + 1
Line is y = 0
We have to find out the volume v of the solid obtained by rotating the region bounded by these curves.
If the region bounded above by the graph of f, below by the x-axis, and on the sides by x=a and x=b is revolved about the x-axis, the volume V of the generated solid is given by \(V = \pi \int\limits^b_a {(f(x))^{2} } \, dx\). We can also obtain solids by revolving curves about the y-axis.
Volume of a solid:
According to washer method:
\(V = \pi \int\limits^b_a {(f(x))^{2} } \, dx\)
Using washer method, where a=0 and b=2, we get
V = \(\pi \int\limits^2_0 {(x+1)^{2} } \, dx\)
= \(\pi[ \frac{(x+1)^{3} }{3} ]0 \ to \ 2\)
= \(\pi [\frac{(3+1)^{3} }{3} -\frac{(0+1)^{3} }{3}]\)
= \(\pi [\frac{27}{3} -\frac{1}{3} ]\)
= \(\pi [\frac{26}{3}]\)
= \(\frac{26}{3} \pi\)
Therefore the volume of a solid is \(\frac{26}{3} \pi\).
