Fill in the table: Amount of salt Total solution Original b RETRY a Removed What is the original amount of solution in gallons? a = 0.12 160 0.2 X 19.2 New
Answers
Step-by-step explanation:
Original Removed New
Amount of salt .12(160) 0 .12(160)
Total solution .2(160) .2a .2(160 - a)
.12(160) = .2(160 - a)

What is the ratio of the number of beaks to the number of legs the chickens and the sheep have on this farm?
Answers
Answer:
8 chickens, 14 sheep needs to be simplified
Step-by-step explanation:
So the chicken has 1 beak and 2 legs and a sheep has 4 legs.
so since there are 8 chickens we know we have 8 beaks
if we mulitply 2 times 8 we get 16
if we mulitply 4 times 14 we get 56
the number of legs is 16+56=72
so we have 8 beaks and 72 legs or 8:72
Divide both sides by 8 to simpilfy u get 1:9 as the answer

Consider the following autonomous first order differential equation.
dy/dx=(−(y−4)2)(y+9)
The critical points are y=4 and y=−9. Classify these critical points (in the given order) as asymptotically stable, unstable, or semi-stable.
(A) semi-stable and unstable
(B) asymptotically stable and asymptotically stable
(C) asymptotically stable and unstable
(D) asymptotically stable and semi-stable
(E) unstable and asymptotically stable
(F) unstable and semi-stable
(G) semi-stable and semi-stable
(H) semi-stable and asymptotically stable
(I) unstable and unstable
Answers
Answer: (D) asymptotically stable and semi-stable
Step-by-step explanation:
Given that:
dy/dx=(−(y−4)2)(y+9)
The critical points are y=4 and y=−9
We have to check the sign of dy/dx in the intervals (-inf,-9), (-9,4), (4, infinity)
In (-inf, -9), dy/dx , let's take y = -10, so we have
(-(-10-4)^2(-10+9) > 0
In (-9,4), let's take y = 0
dy/dx = (-(0-4)^2)(0+9) < 0
In (4, inf), let's take y = 10
So we have (-(10-4^)2(10+9) < 0
So at y = -9, sign change for dy/dx from positive to negative. SO it is asymptotically stable
And at y = 4, sign is negative on both sides. So 4 is semi stable
the difference between the squares of two numbers is 5. four times the square of the first number increased by the square of the second number is 40. find the numbers.
Answers
Answer:
The first number is [tex]\pm 3[/tex] and the second number is [tex]\pm 2[/tex].
Step-by-step explanation:
Create two equations using the given information. Let's set variables for the two numbers as x and y.
"The difference between the squares of two numbers is 5":
[tex]x^2-y^2=5[/tex]We can let x be the first number;
"Four times the square of the first number increased by the square of the second number is 40":
[tex]4x^2 + y^2 =40[/tex]Now we have a system of equations that we can solve for x and y:
[tex]x^2-y^2=5[/tex][tex]4x^2 + y^2 =40[/tex]It looks like [tex]y^2[/tex] can easily be canceled out from both equations if we use the elimination method. Add these equations together.
[tex]5x^2=45[/tex]Divide both sides of the equation by 5.
[tex]x^2=9[/tex]Take the square root of both sides of the equation.
[tex]x= \pm3[/tex]It doesn't matter if we use positive or negative 3, since the variables x and y are both being squared, so the outcome will always be positive.
Substitute either positive or negative 3 into the first equation.
[tex](3)^2-y^2=5[/tex]Evaluate the exponent.
[tex]9-y^2=5[/tex]Subtract 9 from both sides of the equation.
[tex]-y^2=-4[/tex]Divide both sides of the equation by -1 to get rid of the negative sign in front of [tex]y^2[/tex].
[tex]y^2=4[/tex]Square root both sides of the equation.
[tex]y= \pm2[/tex]Again, it doesn't matter if y is positive or negative since it is getting squared regardless.
The first number is [tex]\pm 3[/tex] and the second number is [tex]\pm 2[/tex].

Answers
Answer:

Step-by-step explanation:
Given that,
The tallest building in franklin is two-third the highest of the tallest building in mayville.
The tallest building in mayville is [tex]\dfrac{8013}{16}[/tex] feet
We need to find the height of the tallest building in franklin.
Let f is the height of the tallest building in franklin and m is the height of the highest building in mayville.
ATQ,
[tex]f=\dfrac{2}{3}m[/tex]
We have, m = [tex]\dfrac{8013}{16}[/tex] feet
So,
[tex]f=\dfrac{2}{3}\times \dfrac{8013}{16}\\\\f=\dfrac{2671}{8}\ \text{feet}[/tex]
So, the height of the tallest building in franklin is [tex]\dfrac{2671}{8}\ \text{feet}[/tex].

select all the values of x so g(x) is not a function.
Answers
Answer: The answer is 6 and 9
Step-by-step explanation: We are trying to figure out what makes the chart not a function. A function is is one input equals one output.
so all you have to do is look at the x and look at the number that is already there and just make it repeat.
The value of x so g(x) is not a function is 3, the correct option is A.
We are given that;
The table of x and g(x)
Now,
A function is a relation that assigns exactly one output to each input. In other words, a function is a relation that has no repeated x-values. To check if g(x) is a function, we can look at the table and see if there are any x-values that have more than one corresponding g(x) value. If there are, then g(x) is not a function.
To find the equation of a linear function, we need to know its slope and its y-intercept.
We can plug in any pair of x and g(x) values from the table and solve for b. Now, using x = 3 and g(x) = 8, we get:
g(x) = mx + b 8 = 4(3) + b 8 = 12 + b b = -4
The equation of g(x) is g(x) = 4x - 4
Looking at the table,
we can see that x = 3 has two different g(x) values: 8 and 9.
This means that g(x) is not a function for x = 3.
Therefore, by the function answer will be 3.

Which is the x-intercept for 4x − 2y = 16?
Answers
Answer:
4
Step-by-step explanation:
Remember, the x-intercept of a function is where the graph intersects the x-axis. A function only intersects the x-axis when y = 0.
To find the x-intercept of the function 4x - 2y = 16, lets set y = 0 and solve for x:
4x - 2(0) = 16
4x = 16
x = 4
So the x-intercept of the function would be 4.

Find the largest angle in degrees:
Answers
This triangle is not possible.
A triangular field has sides of lengths 29, 35, and 51 miles. The largest angle of the triangle can be calculated using the Law of Cosines, which is a generalization of the Pythagorean Theorem.
Law of Cosines:The Law of Cosines is a mathematical tool used to calculate the length of a side or the size of an angle of a non-right triangle. It states that the square of any side of a triangle is equal to the sum of the squares of the other two sides,
minus twice the product of these two sides and the cosine of the angle between them.Mathematically, the law of cosines is expressed as: `a^2 = b^2 + c^2 - 2bc cos A`,
where `a` is the unknown side, and `b` and `c` are the known sides of the triangle, and `A` is the angle between sides `b` and `c`.We can use the Law of Cosines to find the largest angle in the triangle as follows:Let `A` be the largest angle,
which is opposite the longest side `51 mi`.Using the Law of Cosines, we have:`
a^2 = b^2 + c^2 - 2bc cos A``51^2 = 29^2 + 35^2 - 2(29)(35) cos A``2601 = 1681 + 1225 - 2030 cos A``2030 cos A = 1225 + 920``cos A = (1225 + 920)/2030``cos A = 2145/2030``cos A ≈ 1.057139``A = cos^-1 (1.057139)`
Since the cosine function is only defined for values between -1 and 1, `1.057139` is not a valid value for `cos A`.

Answers
Answer:
1.21
Step-by-step explanation:
2 liter = 0.0706
3.5 seconds = 0.0583 minutes
0.0706/0.0583 = 1.21 cubic feet/minute
The rate of flow in cubic feet per minute is 1.21 cubic feet/minute if the water flows through a pipe at a rate of 2 liters every 3.5 seconds.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that:
Water flows through a pipe at a rate of 2 liters every 3.5 seconds.
As we know:
2 liter = 0.0706
3.5 seconds = 0.0583 minutes
= 0.0706/0.0583
= 1.21 cubic feet/minute

48 square inches per inch
54 square inches per inch
66 square inches per inch
96 square inches per inch
Answers
Answer:
48 square inches per inch
Step-by-step explanation:
The difference quotient is the average rate of change:
m = ΔA / Δe
m = (A(e+h) − A(e)) / h
m = 12e + 6h
In this case, e = 3 and h = Δe = 5−3 = 2.
m = 12(3) + 6(2)
m = 36 + 12
m = 48
