Answer:
Step-by-step explanation:
[tex]S^{2}[/tex] is ( [tex]q^{2}[/tex][tex]r^{3}[/tex])^2
then
A = [tex]q^{2*2}[/tex][tex]r^{3*2}[/tex]
A = [tex]q^{4}[/tex][tex]r^{6}[/tex]
this looks much better than r^ some big number :D

Which value of x is a solution to this equation?
2x^2 - 4x + 16 = 0
A. X = 3
B. X = -2
C. X = -3
D. X = 2
9514 1404 393
Answer:
no solution
Step-by-step explanation:
The discriminant is ...
b^2 -4ac = (-4)^2 -4(2)(16) = 16 -128 = -112
A negative discriminant means there are no real solutions to the equation.
_____
The complex solutions are 1±i√7.
If we assume the equation has a typographical error and is intended to be ...
2x^2 -4x -16 = 0
The solutions are x = -2 and x = 4.

Answer:
I belive the answer would be the first one. 2^28 x 3^20 x 9^4
Step-by-step explanation:
This is becasue you need to multiply the power on the outside of the parenthesis, (4). 7 times itself 4 times is 28, 5 times itself 4 times is 20, and then use the 4 for the 9. Hope this helps!
Can someone please solve this, i need it quickly
Answer:
3x + y = 20 and x - 2y = - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
(a)
Given
3x + y = 17 ( subtract 3x from both sides )
y = - 3x + 17 ← in slope- intercept form
with slope m = - 3
Para;;el lines have equal slopes , then
y = - 3x + c ← is the partial equation
To find c substitute (4, 8) into the partial equation
8 = - 12 + c ⇒ c = 8 + 12 = 20
y = - 3x + 20 ← in slope- intercept form
Add 3x to both sides
3x + y = 20 ← in standard form
--------------------------------------------------------
(b)
Given
y + 2x = 13 ( subtract 2x from both sides )
y = - 2x + 13 ← in slope- intercept form
with slope m = - 2
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-2}[/tex] = [tex]\frac{1}{2}[/tex] , then
y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation
To find c substitute (2, 3) into the partial equation
3 = 1 + c ⇒ c = 3 - 1 = 2
y = [tex]\frac{1}{2}[/tex] x + 2 ← in slope- intercept form
Multiply through by 2 to clear the fraction
2y = x + 4
x - 2y = - 4 ← in standard form

Answer:
I'm going to also give you how to get the answer... not just the answer.. you will need to know this for a test :/ so learn it :P
Step-by-step explanation:
Sin(30)=12
to remember what Sin and Cos at those speacial angles in degrees are.. just use this Sin(degrees)
Sin(0) = 0/2 =0
Sin(30)= [tex]\sqrt{1}[/tex]/2 = 1/2
Sing(45) = [tex]\sqrt{2}[/tex]/2 = [tex]\sqrt{2}[/tex]/2
Sin(60)=[tex]\sqrt{3}[/tex]/2 = [tex]\sqrt{3}[/tex]/2
Sin(90)=[tex]\sqrt{4}[/tex]/2 = 1
Cos is exactly the same but counts backwards from 90°
Cos(90) = 0/2 =0
Cos(60) = [tex]\sqrt{1}[/tex]/2 = 1/2
Cos(45) = [tex]\sqrt{2}[/tex]/2 = [tex]\sqrt{2}[/tex]/2
Cos(30) = [tex]\sqrt{3}[/tex]/2 = [tex]\sqrt{3}[/tex]/2
Cos(0) =[tex]\sqrt{4}[/tex]/2 = 1
note that the numerators just count from 0,1,2,3,4 , see? you can remember sin and cos now :) since you can count to 4 :P
Sin(30) =12
1/2 =12 while that statement makes no sense.... obviously 1/2 isn't equal to 12 but.. what's being said is that the angle of 30° gives you a side that is 12 units long.
so looking at what I wrote above.. which angle in degrees matches Sin when you look at Cos?
Sin(30)= 1/2 and Cos(60) also = 1/2 huh
sooo β = 60 °

Jada has read 3/5 of a book. she has read 75 so far. how many pages are in the whole book?
Answer: Total number of pages is 125
Step-by-step explanation:
If 3/5 of a book is equal to 75, we can conquer that 1/5 of the book is 25 pages, because 75/3=25.
With this we can do 25 x 5 = 125 total pages.

Answer: x < 4
Step-by-step explanation: To plot an inequality, find the number and go the way the sign is pointing.
In this problem...
The less than sign is pointing left, and the number is 4. We use an open circle because the sign is not equal to. If it was, we would of put a closed circle.
<, or > = Open circle (Not shaded)
≤, or ≥ = Closed circle (Shaded)

The value of w varies jointly with x and y, and w = 5 when x = 3/4 and y =2. What is the value of w when x = 4 and y = 3?
Answer:
A ∝ BCD or A = kBCD (k = constant ), then A varies jointly as B, C and D.
Step-by-step explanation:
The value of 'w' when x = 4 and y = 3 is, 40.
What are ratio and proportion?In its most basic form, a ratio is a comparison between two comparable quantities.
There are two types of proportions One is the direct proportion, whereby increasing one number by a constant k also increases the other quantity by the same constant k, and vice versa.
If one quantity is increased by a constant k, the other will decrease by the same constant k in the case of inverse proportion, and vice versa.
Given, The value of w varies jointly with x and y.
Let, w ∝ xy ⇒ w = kxy.
5 = k×(3/4)×2.
5 = (3/2)k.
k = 10/3.
Now, x = 4 and y = 3.
Therefore,
w = (10/3)×4×3.
w = 40.

Nina buys a small rug in the shape of a kite. The width of the rug is half its height. What are the width and area of the rug? (height 31 inches width 9 inches)
Answer:
[tex]Width = 20\ in[/tex]
[tex]Area = 400\ in^2[/tex]
Step-by-step explanation:
Given
See attachment for kite dimension
Required
Determine the width and the area
From the attachment, the height of the kite is:
[tex]Height = 31\ in + 9\ in[/tex]
[tex]Height = 40\ in[/tex]
The width which is half the height is:
[tex]Width = \frac{1}{2} * Height[/tex]
[tex]Width = \frac{1}{2} * 40\ in[/tex]
[tex]Width = 20\ in[/tex]
The area is:
[tex]Area = \frac{Height * Width}{2}[/tex]
[tex]Area = \frac{40\ in * 20\ in}{2}[/tex]
[tex]Area = 40\ in * 10\ in[/tex]
[tex]Area = 400\ in^2[/tex]

A cylinder has a base diameter of 8ft and a height of 20ft. What is it's volume in cubic ft, to the nearest 10th place?
Answer:
1005.3 ft³
Step-by-step explanation:
cylinder has a base diameter of 8ft and a height of 20ft. What is it's volume in cubic ft, to the nearest 10th place?
Given that:
Base diameter = 8feets
Radius, r = 8/2 = 4 feets
Height h, = 20 feets
Volume of cylinder, V = πr²h
V = π * 4² * 20
V = π * 16 * 20
V = 1005.3096
V = 1005.3096 ft³

The value of a stock increases by 8% each year.
1. Explain why the stock value does not increase by 80% each decade.
2. Does the value increase by more or less than 80% each decade?
Answer:
if it increases 8% each year, the next year it's not 8% of the original, but 8% of the 108% and so forth.
The increase after 10 years is (108%)^10 - 100% which is bigger than 80%.
If the value of a stock increases by 8% each year, then, that is not equal to the value of a stock increases 80% each decade.
What is Percentage Increase?The degree to which a value increases expressed in percent form is known as percentage increase.
Given that, The value of a stock increases by 8% each year.
a) If it increases 8% each year, the next year it's not 8% of the original, but 8% of the 108% and so forth, the incasement in percentage is an exponential increase not a linear increase, so we can't say that, the value of the stock increases 80% each decade
b) Since, (108%)¹⁰ > 80%
Hence, the increase after 10 years is (108%)¹⁰, will be bigger than 80%.
Hence, If the value of a stock increases by 8% each year then, that is not equal to the value of a stock increases 80% each decade
