Answer:
k = 0.2
A = (M / P₀) − 1
Step-by-step explanation:
dP/dt = kP
When t = 0, P = 1000 and dP/dt = 200.
200 = 1000k
k = 0.2
P = M / (1 + Ae⁻ᵏᵗ)
When t = 0, P = P₀.
P₀ = M / (1 + A)
1 + A = M / P₀
A = (M / P₀) − 1

O x = 10.3 and y = 17.9
O x = 8 and y = 21
O x = 7 and y = 12
x = 12 and y = 7
Answers
Answer:
x=8 and y=21
Step-by-step explanation:
12x-28=7x+12 (the 2 angles are equivalent)
12x-7x=12+28
5x=40
x=8
9y-77 + 12x-28 =180 (the sum of those 2 angles is a flat angle (180°))
9y-77+12*8-28=180
9y=180+28+77-96
9y=189
y=21

A board 14 1/4 inches long is cut from a board that is 4 feet long. If the width of the saw cut is 1/8 inch, what is the length of the remaining piece?
Answers
Answer:
Step-by-step explanation:
From the given information;
since;
1 feet = 12 inches long
Then, 4 feet = (4 × 12)inches long
= 48 inches long
Thus, the length of the remaining piece is calculated as follows:
Length of remaining piece = Total length of piece - (piece that was being cut + width )
[tex]= 48 - (14 \dfrac{1}{4}+ \dfrac{1}{8})[/tex]
[tex]= 48 - ( \dfrac{57}{4}+ \dfrac{1}{8})[/tex]
[tex]= 48 - ( \dfrac{114+1}{8})[/tex]
[tex]= 48 - ( \dfrac{115}{8})[/tex]

Which of the following is an equation of a proportional relationship?
Group of answer choices
y = 25x
y = 5x + 25
Describe what the equation you chose above could represent. In other words, what real-world situation could this equation be used?
Answers
Answer:
Both are proportional, because as the value of x change (increases or decreases), the value of y changes (increases or decreases).
The first equation (y = 25x) could represent that amount of teachers per students. If x = teachers (let's say there is 1 teacher), then y = students (1 teacher would teach a class of 25 students).
The second equation (y = 5x + 25) could represent the amount of money you could earn babysitting. The starting/base amount would be $25, and you would earn $5 more for every hour you babysat.

Answer:

Hope This Helps :)
Answer:
Joey's Cafe sold 20% regular coffee and 80% decaffeinated coffee.
Step-by-step explanation:
We are given that the cafe served 35 coffees. We are also told that of those 35 coffees, 7 coffees were regular.
Therefore, we can divide the number of regular coffees by the total number of coffees sold to get the percentage of regular coffees.
Our ratio will be set up as 7 regular coffees : 35 total coffees. We can also represent this as a fraction.
[tex]\displaystyle\frac{7}{35}=\frac{1}{5}\\\\\frac{1}{5}=0.2\\\\0.2 \times 100 = 20\%[/tex]
Therefore, of the coffees sold at the cafe, 20% of those coffees were regular.
Additionally, we can subtract this percentage from 100 to find out how much of the sales were decaffeinated coffee.
[tex]100\% - 20\% = 80\%[/tex]
Joey's Cafe sold 80% decaffeinated coffee.

Option A (5, 0)
Step-by-step explanation:
Step 1: Determine what is a solution
To find a solution of two lines, it has to be in the area where both of the colors intersect. As you can see the red line goes up and the blue line goes down, but there is a shaded region where there is just white, just blue, just red, and the red and blue. The shaded region where both red and blue is, that is where the solutions are.
(5, 0) -> This means that the x-value is 5 and the y-value is 0 meaning that it is in the area where there is both red and blue.
(1, -3) -> This means that the x-value is 1 and the y-value is -3 meaning that it is in the area where there is only red.
(3, 3) -> This means that the x-value is 3 and the y-value is 3 meaning that it is in the area where there is only blue.
(2, 1) -> This means that the x-value is 2 and the y-value is 1 meaning that it is in the area where there is only blue.
Answer: Option A (5, 0)
Vance used the associative property to write (4.5 m + StartFraction 7 Over 8 EndFraction) minus 9 as the equivalent expression 4.5 m (StartFraction 7 Over 8 EndFraction minus 9). Did Vance apply the associative property correctly? Why or why not?
Yes, the terms with variables should be written first.
Yes, the terms can be regrouped and still be equivalent.
No, the order of the terms should have been changed.
No, the addition symbol was dropped in the second expression.
Answers
Answer: D
Step-by-step explanation:
No, the addition symbol was dropped in the second expression is not correct.
What is Expression?An expression is combination of variables, numbers and operators.
No, Vance did not apply the associative property correctly.
The associative property states that the grouping of terms in an expression can be changed without affecting the value of the expression.
However, in this case, Vance changed the order of the terms, but did not actually group them in a different way.
Additionally, Vance dropped the subtraction symbol in the second expression, which is incorrect.
The correct equivalent expression using the associative property would be:
(4.5 m + 7/8) - 9 = 4.5 m + (7/8 - 9)
From there, we could simplify the expression further, if needed.
Hence, No, the addition symbol was dropped in the second expression.

[tex]\frac{2}{7}[/tex]
Step-by-step explanation:
In order to find the slope of a line you must find where the points intersect, use the formula for slope, substitute values, and simplify if needed.
In this case we were already given the points for slope:
[tex]P1=(-4,-4) = (x1,y1)[/tex]
[tex]P2=(-2,3)=(x2,y2)[/tex]
Slope formula:
[tex]slope = \frac{y2-y1}{x2-x1}[/tex]
Now substitute:
[tex]\frac{-2--4}{3--4}[/tex]
Solve using KCC: (Keep, Change, Change)
[tex]-2+4=2[/tex]
[tex]3+4=7[/tex]
=[tex]\frac{2}{7}[/tex]
Because the slope isn't a negative you do not need to simplify the answer.
Hope this helps.

PLEASE HELP OMG calculate the slope of the graph below at the point (-1,5)
f(x) = x^5 + 1/x^3 +7
Answers
Answer:
The slope of the graph at x=-1 is 2
Step-by-step explanation:
Instant rate of change
Given a real function f(x), the instant rate of change with respect to x is defined as the derivative of f which coincides with the instant value of the slope of the tangent line in the point (x,y).
We have the function:
[tex]\displaystyle f(x) = x^5+\frac{1}{x^3}+7[/tex]
Prepare the function to apply the power rule of the derivative:
[tex]\displaystyle f(x) = x^5+x^{-3}+7[/tex]
Recall the power rule:
[tex](x^n)' = nx^{n-1}[/tex]
Also, the derivative of a constant is zero.
Taking the derivative:
[tex]\displaystyle f'(x) = 5x^4-3x^{-4}[/tex]
Evaluating for x=-1:
[tex]\displaystyle f'(-1) = 5(-1)^4-3(-1)^{-4}[/tex]
[tex]\displaystyle f'(-1) = 5*1-3*1=2[/tex]
The slope of the graph at x=-1 is 2

Solve the system of equations.
x + 3y = -1
2x + 2y = 6
Answers
Answer:
y= -2
x = 5
Step-by-step explanation:
Multiply the top equation by 2 to get
2x + 6y = -2
then subtract the bottom equation by the new equation to get
2x + 6y = -2
--------------------
2x + 2y = 6
which is
4y = -8
y = -2
If y = -2
Then plug -2 into y in the top equation to get x + 3(-2) = -1 and simplify which is
x + (-6) and add 6 to both sides to get x = -1 + 6
which is x = 5
