The rate of change of y with respect to x is proportional to y2. Write a differential equation for the statement. (Use k for the constant of proportionality.)
Answers
Answer:
[tex]\dfrac{dy}{dx}\ = ky_2[/tex]
Step-by-step explanation:
The rate of change of y with respect to x is expressed as shown;
[tex]\dfrac{dy}{dx}[/tex]
If the rate of change of y with respect to x is proportional to y2, this is expressed as;
[tex]\dfrac{dy}{dx}\ \alpha \ y_2[/tex]
If we remove the proportionality sign, a proportionality constant will be introduced as shown;
[tex]\dfrac{dy}{dx}\ = ky_2[/tex]
where k is the constant of proportionality.
Hence the differential equation for the statement is expressed as [tex]\dfrac{dy}{dx}\ = ky_2[/tex]

The school Library was building a new one-room addition. the architects drawing shown below uses the scale 1/8 in = 1ft
Dimensions: 2 1/4 and 3 3/16
Using the dimensions indicated on the drawing, what is the total area of the new room?
Answers
Answer:
the total are is 459
Step-by-step explanation:
3 3/16 divided by 1/8 = 25 1/2 or 25.5
2 1/4 divided by 1/8 = 18
so 18 x 25.5 = 459
hope this helps
The total area of the new room is 459.
What is the scale factor?The ratio between comparable measurements of an item and a representation of that thing is known as a scale factor in arithmetic.
WE are given that school Library was building a new one-room addition. the architects drawing shown below uses the scale 1/8 in = 1ft
Dimensions: 2 1/4 and 3 3/16
Therefore,
3 3/16 divided by 1/8 = 51/2 or 25.5
2 1/4 divided by 1/8 = 18
Thus we have the area
= 18 x 25.5
Area = 459
The total area of the new room is 459.

A new truck costing $60,000 with a residual value of $6,000
Answers
4 hours worked for $12; 7 hrs worked for $28 are the pair of ratios equal?
Answers
Answer:
no they're not equal
Step-by-step explanation:
you can find the ratio by dividing 12/4 and 28/7. 12/4 = 3 and 28/7 = 4. 3 and 4 are not equal, so no.
No, the pair of ratios are not equal
Explanation:
To see if the ratios are equal, we have to simplify the both of them. For the first one, it’s 12/4. That is equivalent to 3/1. This means she gets $3 for every hour. Now to the next one. The ratio is 28/7 and simplify that into 4/1. That means he gets $4 each hour. So they are different meaning the pair of ratios are not equal. Good luck on your test! Have a good day.

Write an equation in standard form for the line, where the points (-2, -1) and (0, 4) are on the line
Answers
Answer:
An equation in standard form for the line is:
[tex]\frac{5}{2}x-y=-4[/tex]
Step-by-step explanation:
Given the points
(-2, -1) and (0, 4)The slope between two points
[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-2,\:-1\right),\:\left(x_2,\:y_2\right)=\left(0,\:4\right)[/tex]
[tex]m=\frac{4-\left(-1\right)}{0-\left(-2\right)}[/tex]
[tex]m=\frac{5}{2}[/tex]
Writing the equation in point-slope form
As the point-slope form of the line equation is defined by
[tex]y-y_1=m\left(x-x_1\right)[/tex]
Putting the point (-2, -1) and the slope m=1 in the line equation
[tex]y-\left(-1\right)=\frac{5}{2}\left(x-\left(-2\right)\right)[/tex]
[tex]y+1=\frac{5}{2}\left(x+2\right)[/tex]
[tex]y=\frac{5}{2}x+4[/tex]
Writing the equation in the standard form form
As we know that the equation in the standard form is
[tex]Ax+By=C[/tex]
where x and y are variables and A, B and C are constants
so
[tex]y=\frac{5}{2}x+4[/tex]
[tex]\frac{5}{2}x-y=-4[/tex]
Therefore, an equation in standard form for the line is:
[tex]\frac{5}{2}x-y=-4[/tex]

A cube has a volume of 216 cubic inches. What is the length of each edge of the cube?
Answers
Answer:
Each side is 6 units.
Step-by-step explanation:
The problem is not how to do the question. The problem is how to get your calculator to do the question.
V = s^3
s = ?
V = 216
So what you need is the cube root of 216
s^3 = 216
cube root(s^3) = cube root(216)
s = cube root 216
Your calculator should have a y^x or x ^y key.
Put in 216
Press the y^x key or the x^y key
Put in 0.33333333333

General Formulas and Concepts:
Order of Operations: BPEMDASExpand by FOIL (First Outside Inside Last)Standard Form: f(x) = ax² + bx + cVertex Form: f(x) = a(bx + c)² + dStep-by-step explanation:
Step 1: Define function
f(x) = 3(x + 1)² - 2
Step 2: Find Standard Form
Expand by FOILing: f(x) = 3(x² + 2x + 1) - 2Distribute 3: f(x) = 3x² + 6x + 3 - 2Combine like terms (constants): f(x) = 3x² + 6x + 1Step-by-step explanation:
f(x)=3(x+1)^2-2
= 3 [x^2 + 2x + 1 ] -2
=3x^2 + 6x +3-2
=3x^2 + 6x + 1
f(x)=ax^2+bx+c
ax^2+bx+c = 3x^2 + 6x + 1

See the explanation for a 'tip'
Explanation:
Quotient means 'the answer after dividing'.
If you get really stuck this is one (bit long) way of dealing with it.
Firstly lets for the moment forget about the negative and just deal with
-96÷12
Write as 96 12
Notice that both numbers are even so we can divide by 2
96÷2=48
12÷2=6
Again they are both even
48÷2=24
6÷2=3
The two digits of 24 are such that
2+4=6
and 6 is exactly divisible by 3 so 24 is also exactly divisible by 3. So now we can do this:
24÷3=8
3÷3=1
Now we put the negative back in giving −8
