b. M=kxa^3/p^2; b. a =
[tex]a = \sqrt[3]{\frac{Mp^{2}}{kx} }[/tex]
Step-by-step explanation:
For a. F=GMm/r^2; a. M =
To solve for M, we will rearrange the given equation F=GMm/r^2 such that M is the subject of the formula
From
F=GMm/r^2
[tex]F = \frac{GMm}{r^{2} }[/tex]
First, Cross multiplication, we then get
[tex]Fr^{2} = GMm[/tex]
Now, divide both sides by [tex]Gm[/tex]
[tex]\frac{Fr^{2} }{Gm} = \frac{GMm}{Gm} \\[/tex]
The equation becomes
[tex]\frac{Fr^{2} }{Gm} = M[/tex]
∴ [tex]M = \frac{Fr^{2} }{Gm}[/tex]
For a. F=GMm/r^2; b. r =
Also, to solve for r, we will rearrange the given equation F=GMm/r^2 such that r is the subject of the formula
From
F=GMm/r^2
[tex]F = \frac{GMm}{r^{2} }[/tex]
First, Cross multiplication, we then get
[tex]Fr^{2} = GMm[/tex]
Now, divide both sides by [tex]F[/tex], Such that we have
[tex]\frac{Fr^{2} }{F} = \frac{GMm}{F} \\[/tex]
Then, [tex]r^{2} = \frac{GMm}{F} \\[/tex]
∴ [tex]r = \sqrt{\frac{GMm}{F} \\}[/tex]
For b. M=kxa^3/p^2; a. P =
To solve for P, we will rearrange the given equation M=kxa^3/p^2 such that P becomes the subject of the formula
From
M=kxa^3/p^2
[tex]M = \frac{kxa^{3}}{p^{2} } \\[/tex]
First, Cross multiply, we then get
[tex]Mp^{2} = kxa^{3}[/tex]
Divide both sides by [tex]M[/tex], such that the equation becomes
[tex]\frac{Mp^{2} }{M} = \frac{kxa^{3}}{M}[/tex]
Then, [tex]p^{2} = \frac{kxa^{3}}{M}[/tex]
∴ [tex]p = \sqrt{\frac{kxa^{3}}{M}}[/tex]
For b. M=kxa^3/p^2; b. a =
To solve for a, we will rearrange the given equation M=kxa^3/p^2 such that a becomes the subject of the formula
From
M=kxa^3/p^2
[tex]M = \frac{kxa^{3}}{p^{2} } \\[/tex]
First, Cross multiply, we then get
[tex]Mp^{2} = kxa^{3}[/tex]
Now, Divide both sides by [tex]kx[/tex], such that the equation gives
[tex]\frac{Mp^{2}}{kx} = \frac{ kxa^{3}}{kx}[/tex]
Then, [tex]\frac{Mp^{2}}{kx} = a^{3}[/tex]
[tex]a^{3} = \frac{Mp^{2}}{kx}[/tex]
∴ [tex]a = \sqrt[3]{\frac{Mp^{2}}{kx} }[/tex]

(1 point) Find the volume of the parallelepiped with one vertex at (4,2,4), and adjacent vertices at (6,3,8), (6,1,10), and (0,6,3)
Answer:
8 cubic units
Step-by-step explanation:
Let he vertices of the parallelepiped be A = (4,2,4), B= (6,3,8), C = (6,1,10) and D = (0,6,3)
The edges of the parallelepiped are
AB = (6,3,8) - (4,2,4) = (2,1,4)
AC = (6,1,10) - (4,2,4) = (2,-1,6)
AD = (0,6,3) - (4,2,4) = (-4,4,-1)
Therefore the volume of the parallelopiped is = |[AB,AC,AD]|

Step-by-step explanation:
Using the formula provided, [tex]a = \frac{1}{2}h(b_1+b_2)[/tex], substituting the height (5), b1 (8) and b2 (12), we can solve for the formula.
[tex]a = \frac{1}{2}\cdot5(8+12)\\\\a = \frac{1}{2}\cdot5(20)\\\\a = \frac{1}{2}100\\\\a = 50[/tex]
Hope this helped!
Answer:
50 units²
Step-by-step explanation:
The area of a trapezoid can be found using the following formula.
[tex]A=\frac{1}{2}h(b_{1} +b_{2} )[/tex]
The height of the trapezoid is 5 units. The bases are 8 units and 12 units.
[tex]h= 5 \\b_{1} = 8\\b_{2} = 12[/tex]
Substitute the values into the formula.
[tex]A=\frac{1}{2}*5(8+12)[/tex]
Solve inside the parentheses. Add 8 and 12.
8+12=20
[tex]A=\frac{1}{2}*5(20)[/tex]
Multiply 5 and 20.
5*20= 100
[tex]A=\frac{1}{2}*100[/tex]
Multiply 1/2 and 100 or divide 100 by 2.
100 * 1/2= 50 or 100/2= 50
[tex]A= 50[/tex]
Add appropriate units. For this problem, the units are units².
[tex]A= 50 units^2[/tex]
The area of the trapezoid is 50 square units.

What are some methods for finding the distance between points A and B? You can use the pen tool to explore different options on the number line?
Answer:
Ok, the straightforward thing you can do, when you have a number line like in this situation, you can just "count" the number of units that are between A and B.
Now, a more correct way:
First, A is located at the value -3, then we can write:
A = -3.
And B is located at the value 5, then:
B = 5.
Now, the distance between A and B is equivalent to the difference between A and B:
D = B - A = 5 - (-3) = 8
The distance between A and B is 8 units.

Solve each of the following equations. Be sure to check your solutions.
3x-5=2.5x+3-(x-4)
Answer: x=8
Step-by-step explanation:
3x - 5= 2.5x + 3 -(x-4) apply the distributive property
3x -5 = 2.5x + 3 - x + 4 combine like terms on the right side
3x - 5 = 1.5x + 7 Add 5 to both sides
+5 +5
3x = 1.5x + 12 subtract 1.5x from both sides
-1.5x -15.x
1.5x = 12 Now divide both sides by 1.5
x = 8

If 20% of x is y, and 30% of y is z, then what percent of x is z?
Your answer is 6% of x.
We can write the given information as equations to find the answer:
Another way to write "20% of x" is to write 0.2x, so therefore 0.2x = y
You can also write "30% of y" as 0.3y, so 0.3y = z
Now we can substitute in the first equation to the second equation, as we know what y equals in terms of x:
0.3(0.2x) = z
Multiplying out we get:
0.06x = z, and 0.06 as a percentage is 6%

A rectangle has a perimeter of 60 inches. The length of the rectangle is 3 inches less than twice the width
What is the length of the rectangle?
Answer:
length = 19 units
Step-by-step explanation:
width = x
length = 2x-3
width = 11 units
length = 2(11)-3
length = 22-3
length = 19 units
perimeter = 11 + 11 + 19 + 19 = 60 units
The perimeter of a shape is the sum of the side lengths of the shape. The length of the rectangle is 19 units.
Given that:
[tex]Perimeter = 60[/tex]
[tex]Length = 2 \times Width -3[/tex]
The perimeter of a rectangle is:
[tex]Perimeter = 2 \times (Length + Width)[/tex]
So, we have:
[tex]60= 2 \times (2\times Width - 3+ Width)[/tex]
Divide both sides by 2
[tex]30= 2\times Width - 3+ Width[/tex]
Collect like terms
[tex]3 + 30= 2\times Width + Width[/tex]
[tex]33= 3Width[/tex]
Divide both sides by 3
[tex]11= Width[/tex]
Rewrite as:
[tex]Width = 11[/tex]
Recall that: [tex]Length = 2 \times Width -3[/tex]
[tex]Length = 2 \times 11 - 3[/tex]
[tex]Length = 22- 3[/tex]
[tex]Length = 19[/tex]
Hence, the length of the rectangle is 19 units.

Write g(x) = 4x2 + 88x in vertex form. The function written in vertex form is g(x) = (x +11)2 + .
Answer:
y = 4(x + 11)² - 484
Step-by-step explanation:
y = 4x² + 88x
factor the expression
y = 4(x² + 22x)
complete the square
y + ? = 4(x² + 22x + ?)
y + ? = 4(x² + 22x + 121)
add 4 • 121 to the left side
y + 4 • 121 = 4(x² + 22x + 121)
multiply
y + 484 = 4(x² + 22x + 121)
y + 484 = 4(x + 11)²
subtract both sides by 484
y = 4(x + 11)² - 484
Answer:
y = 4(x + 11)² - 484

The acceleration of an object due to gravity is 32 feet per second. What is acceleration due to gravity in inches per second?
Answer:
384 inches per second.
Step-by-step explanation:
We are given that the acceleration of an object due to gravity is 32 feet per second.
And we want to find the acceleration in inches per second.
The acceleration can be represented as a ratio of 32 feet : second. This can be written as a fraction:
[tex]\displaystyle \frac{32\text{ feet}}{\text{second}}[/tex]
Use dimensional analysis. It is known that there is 12 inches in a feet. So, multiply by 12in/feet:
[tex]\displaystyle = \frac{32\text{ feet}}{\text{second}}\cdot\frac{12\text{ inches}}{\text{feet}}[/tex]
Cancel like units:
[tex]\displaystyle =\frac{32\cdot 12\text{ inches}}{\text{second}}[/tex]
Multiply:
[tex]\displaystyle =\frac{384\text{ inches}}{\text{second}}[/tex]
In conclusion, our answer is 384 inches per second.

Answer:
A
Step-by-step explanation:
So we have the piecewise function:
[tex]f(x)= \begin{cases}\sqrt{2x} & \text{if }x<3 \\2x+10 & \text{if }3\leq x<8\\42&\text{if } x\geq 8\end{cases}[/tex]
And we want to find f(8).
Since our input value is 8, choose the equation that fits our input.
The first equation demand x to be less than 3. 8 is not less than 3, so we won't use that.
The second equation demand x to e greater than or equal to 3 and less than 8. 8 is not less than 8. So, we won't use that.
The third equation demands x to be greater than or equal to 8. 8 is greater than or equal to 8, so we'll use the third equation.
So:
[tex]f(x)=42\text{ if }x\geq 8[/tex]
[tex]f(8)=42[/tex]

Identify whether each of the datasets is quantitative or qualitative a. Types of computer software used in a database management system. b. Life-lengths of laser printers c. Brands of calculators used by 100 engineering students on campus d. Mileage attained by 12 automobiles powered by alcohol
Answer:
a. Types of computer software used in a database management system. =Qualitative
b. Life-lengths of laser printers =Quantitative
c. Brands of calculators used by 100 engineering students on campus =Qualitative
d. Mileage attained by 12 automobiles powered by alcohol= Quantitative
Step-by-step explanation:
Data is described as quantitative when it deals with numeric values whereas qualitative data is categorical in nature. Quantitative data tells us how much, how many, or the frequency of occurrence of certain variables. Qualitative data provides answers to the what, why, which, and where questions.
1. Types of computer software are not numeric variables as they answer the 'what' question.
2. Length deals with numbers, so the life-lengths of laser printers is a quantitative variable.
3. Brands of calculators are categorical data and are thus qualitative.
4. Mileage is a numerical variable and is thus quantitative.
