The rate of change of the given simple index over 1 day is -0.9%.
What is rate of change?When something has a constant rate of change, one quantity changes in relation to the other.
Given that;
Stock A opens on Monday with 10000 shares at $5.50 per share.
Stock B opens on Monday with 8000 shares at $6.25 per share.
Stock A opens on Tuesday at $5.80 per share, and stock B opens on Tuesday at $6.65 per share.
Total value of the simple index at Monday is;
= (10000×5.50) + (8000×6.25)
= 55,000 + 50,000
= 105,000
The total value of the simple index at Tuesday is;
= (10000×5.80) + (8000×6.65)
= 58,000 + 53,200
= 111,200
The rate of change of this simple index over 1 day is;
= (111,200-105,000)/(10000-8000) -1
= 6,200/2000 - 1
= 3.1 - 1
= 2.1
Hence, the rate of change of the given simple index over 1 day is -0.9%.

Please answer ! Polynomials and Factoring problems. Thank you!
Answer: The answer to your first question is b^2+2b-8. You second answer is y^2-4y+3.
Step-by-step explanation: Now, these questions deal with the FOIL method commonly taught in schools. The FOIL method is to turn factored binomials back into quadratics. Let's first go over what FOIL means.
F - First. So you multiply the first terms in each set of parenthesis, so b times b and y times y make b squared and y squared.
O - Outer. Multiply the two outer terms together, so b times -2 and y times -3. Remeber to pay attention to your signs when you multiply during these probelms!
I- Inner. Multiply the two inner terms together. so 4 times b and -1 times y. Again, make sure the signs are incorporated!
L - Last. Multiply the last terms in the binomials. So 4 times -2 and -1 times -3.
Now that we have our numbers, we have expanded quadratics that look like these:
b^2 -2b+4b-8 and y^2-3y-y+3
Now combine the two middle terms into +2b and -4y, and your answers are b^2+2b-8 and y^2-4y+3.

What are permutation and combination?A permutation is an act of putting things or elements in the right sequence. Combinations are a method of picking things or pieces from a collection of objects or sets when the sequence of the objects is irrelevant.
Laura will wear a pair of mittens, a scarf, and a jacket as she leaves the house.
She has two pairs of mittens to choose from, six scarves chosen from, and three jackets to choose from.
Then the number of ways will be

✥ 19 more than the number c is 4.
[tex]\diamond[/tex] [tex]\large\textsf{\textbf{\underline{\underline{Answer and how to solve:-}}}}[/tex]
◆ First, the word "more" indicates that we add.
Here we have 19 more than c, so we add c plus 19, which looks as follows:-
✳︎ [tex]\sf{19+c}[/tex]
This expression is equal to 4:-
✳︎[tex]\sf{19+c=4}[/tex]
If you also need to find c, subtract 19 on both sides:-
c=-15So we conclude that the value of c is -15.
Good luck with your studies.- -- - - - - - - - - - - - - - - - - - - - - - - - - -
Answer:
19 + c = 4
Step-by-step explanation:
Given:
19 more than the number c is 4We know that:
The word "more" means addition between two numbers. The word "is" means two terms or two expressions are equivalent.Therefore, we can make the following replacements:
"19" ⇒ "19""more" ⇒ "+""c" ⇒ "c""is" ⇒ "=""4" ⇒ "4"When we replace the bolded text in the statement, we get;
⇒ 19 more than the number c is 4
⇒ 19 more than the number c is 4 ["19" ⇒ "19"]
⇒ 19 + than the number c is 4 ["more" ⇒ "+"]
⇒ 19 + c is 4 ["than the number c" ⇒ "c"]
⇒ 19 + c = 4 ["is" ⇒ "="]
⇒ 19 + c = 4 ["4" ⇒ "4"]
Thus, the expression/equation that represents the statement is [tex]\small\text{19 + c = 4.}[/tex]

Step-by-step explanation:
The Allied Taxi Company charges $2. 50 to pick up a passenger and then adds $1. 95 per mile. Isaac was charged $27. 46 to go from one city to another. If x represents the number of miles driven by the taxi, which linear equation can be used to solve this problem, and how many miles did Isaac travel, rounded to the nearest tenth? 1. 95x 2. 50 = 27. 46; Isaac traveled 15. 4 miles. 1. 95x 2. 50 = 27. 46; Isaac traveled 12. 8 miles. 2. 50x 1. 95 = 27. 46; Isaac traveled 11. 8 miles. 2. 50x 1. 95 = 27. 46; Isaac traveled 10. 2 miles.

A 5kg sample of plutonium-239 has a half-life of 21,400 years by emitting a 5.157 mev (million or mega electron volts) alpha particles. assume that the rate of decay is constant, how long will it take for the sample to degrade to 4.5kg?
Using an exponential function, it is found that it will take 3,252 years for the sample to degrade to 4.5kg.
What is the exponential function for the amount of a substance?It is given by:
[tex]A(t) = Pe^{-kt}[/tex]
In which:
P is the initial amount. k is the decay rate, as a decimal.The half-life is of 21,400 years, hence, A(21400) = 0.5P, and this is used to find k.
[tex]A(t) = Pe^{-kt}[/tex]
[tex]0.5P = Pe^{-21400k}[/tex]
[tex]e^{-21400k} = 0.5[/tex]
[tex]\ln{e^{-21400k}} = \ln{0.5}[/tex]
[tex]-21400k = \ln{0.5}[/tex]
[tex]k = -\frac{\ln{0.5}}{21400}}[/tex]
k = -0.00003239005
Hence, considering the initial mass is of P = 5 kg, the amount after t years is given by:
[tex]A(t) = 5e^{-0.00003239005t}[/tex]
The amount will be of 4.5 kg at t for which A(t) = 4.5, hence:
[tex]4.5 = 5e^{-0.00003239005t}[/tex]
[tex]e^{-0.00003239005t} = 0.9[/tex]
[tex]\ln{e^{-0.00003239005t}} = \ln{0.9}[/tex]
[tex]-0.00003239005t = \ln{0.9}[/tex]
[tex]t = -\frac{\ln{0.9}}{0.00003239005}[/tex]
t = 3252.
