Problem 5
Answer: Yes the points are coplanar
------------------------
Explanation:
Note how all four points are in the same plane, aka face, along the top of the 3D block. The term "coplanar" simply means "all in the same plane", so that's why the points are coplanar.
In contrast, the set of points {H,J,K,Z} are not all coplanar because H,J,K are in the top plane, while Z is not.
===========================================================
Problem 6
Answer: line segments WX, XY, and XK
------------------------
Explanation:
All three lines mentioned above involve the letter X in some fashion. The order doesn't matter. Also, those lines intersect at the common point X.
===========================================================
Problem 7
Answer: point W
------------------------
Explanation:
The plane WXYZ is the bottom face, in which we can think of as the floor of the building. The segment HW is from the floor and goes up vertically. We can consider this to be like a pole beam of the structure. The plane and segment both have point W in common. Note that the letter "W" is found in the sequences WXYZ and HW, and it's the only common letter.
===========================================================
Problem 8
Answer: The points are not collinear
------------------------
Explanation:
To be collinear, the points must all be on the same straight line. We see that isn't the case with points W, X and Y.

1 - n6 =
Answer:
-(n -1)(n^2 + n + 1)(n + 1)(n^2 - n + 1).
Step-by-step explanation:
1 - n^6 = (1 - n^3)(1 + n^3)
1 - n^3 = -(n -1)(n^2 + n + 1) and
1 + n^3 = (n + 1)(n^2 - n + 1)
So Substituting we have:
-(n -1)(n^2 + n + 1)(n + 1)(n^2 - n + 1)
Prove this
1-tan^2x/1+tan^2x=cos^2x-sin^2x
Answer:
see explanation
Step-by-step explanation:
Using the identity
tan x = [tex]\frac{sinx}{cosx}[/tex]
Consider the left side
[tex]\frac{1-tan^2x}{1+tan^2x}[/tex]
= [tex]\frac{1-\frac{sin^2x}{cos^2x} }{1+\frac{sin^2x}{cos^2x} }[/tex] ( multiply numerator and denominator by cos²x to clear fractions
= [tex]\frac{cos^2x-sin^2x}{cos^2x+sin^2x}[/tex] ← ( cos²x + sin²x = 1 ]
= cos²x - sin²x
= right side , thus proven

Answer:
6/25
Step-by-step explanation:
.24 = 24/100 = 6/25
Answer:
6/25
Step-by-step explanation:
step 1 The decimal number = 0.24
step 2 Write it as a fraction
0.24/1
step 3 Multiply 100 to both numerator & denominator
(0.24 x 100)/(1 x 100) = 24/100
It can be written as 24% = 24/100 or 24/100
step 4 To simplify 24/100 to its lowest terms, find LCM (Least Common Multiple) for 24 & 100.
4 is the LCM for 24 & 100
step 5 divide numerator & denominator by 4
24/100 = (24 / 4) / (100 / 4)
= 6/25
6/25 is a simplest fraction for the decimal point number 0.24
did i do it correctly if i didnt can u please answer it correctly and tell me how u did it
Answer:
You have done it wrong.
Step-by-step explanation:
4 3/7 - 5/7 = 3 5/7
We can change the equation to a improper fraction first.
4 3/7 = 4*7+3 = 31/7
31-5 = 26
Therefore the answer is 26/7.
simplify
The answer is equal to 26/7, or 21/7 + 5/7
Which is 3 5/7
Sorry but you did it wrong...
First you gonna make 4[tex]\frac{3}{7}[/tex] become 3[tex]\frac{10}{7}[/tex] ( 4 -> 3 [tex]\frac{7}{7}[/tex] - *you need to make it become the same denominator)
Lets do it: 3[tex]\frac{10}{7}[/tex] - [tex]\frac{5}{7}[/tex] = ...
Because in [tex]\frac{5}{7}[/tex] doesn't have a whole number so you will still keep 3
3[tex]\frac{10}{7}[/tex] - [tex]\frac{5}{7}[/tex] = 3.....
Next, you gonna subtract [tex]\frac{10}{7}[/tex] - [tex]\frac{5}{7}[/tex] = [tex]\frac{10-5}{7}[/tex] = [tex]\frac{5}{7}[/tex]
3[tex]\frac{10}{7}[/tex] - [tex]\frac{5}{7}[/tex] = 3[tex]\frac{5}{7}[/tex]
SO the answer for 4[tex]\frac{3}{7}[/tex] - [tex]\frac{5}{7}[/tex] is 3[tex]\frac{5}{7}[/tex]

please help me I am stuck on this question
Answer:
(a) $3.00
(b)(i) $33.00
(b)(ii) $322.50
Step-by-step explanation:
(a)
100% = $20.00
1% = 100%/100 = 20/100 = $0.20
15% = 1%×15 = 0.2×15 = $3.00
so, he actually has to pay $20 + $3 = $23 per toaster.
or shorter and direct, since we calculate the extra 15% based on the original 100%, we can say he has to pay 115% of the basic price.
115% = 0.2×115 or = 100%×1.15 = 20×1.15
0.2 × 115 = $23
20 × 1.15 = $23
so, you can see the several ways to get to the result.
in any case, the profit is $26-$23 = $3 per toaster.
(b)(i)
100% new price = 100% old price + 20% = 120% old price
or 100% old price × 1.2
100% new price per toaster = 20×1.2 = $24.00
the new tax is increased TO 25% (not by 25%) be careful to see that detail.
so, we need to add 25% of the new price.
125% new price = 24×1.25 = $30.00
so, in order to make again $3 profit, the customer has to pay now $30+$3 = $33.00
(b)(ii)
100% (b)(i) selling price = $33.00
30% more means 130% of that, or 1.3×100%
33×1.3 = $42.90
so, the profit per toaster is now 42.90 - 30 = $12.90
when selling 25 of these toasters the profit is then
25×12.90 = $322.50

Answer:

Answer:
a. F=1.8c + 32
b. 71.6 degrees Fahrenheit
c. c=(F-32)/1.8
d. 28.3 degrees Celcius
Step-by-step explanation:
a. Given the two data points we can create an equation in slope-intercept form.
The y-intercept is 32
Slope can be found by doing 212-32/100-0 = 180/100 = 1.8
F=1.8c + 32
b. We can use this formula to solve for Fahrenheit
F=1.8(22)+32
F=71.6 degrees
c. Isolate c
F-32=1.8c
(F-32)/1.8=c
d. We can use this formula to solve for Celcius
(83-32)/1.8=c
c= 28.3333333 degrees
We can round that to 28.3 degrees Celcius
Answer:
a)F =1.8C +32
b) f(22) = 68 F
c) C = 5/9F -17 7/9
d) 28.3
slope= 5/9
B= -17 7/9
Step-by-step explanation:
x1 y1 x2 y2
0 32 100 212
(Y2-Y1) (212)-(32)= 180 ΔY 180
(X2-X1) (100)-(0)= 100 ΔX 100
slope= 1 4/5
B= 32
Y =1.8X +32
Find the probability of “landing” in the shaded region of the figures below. Round your answer to the nearest hundredth.
3. Square with side length 40 ft
Answer:
Area of the square:
A = a² = 40² = 1600 ft²Area of the circle:
A = πr² = 3.14*(40/2)² = 1256 ft²Probability of landing in the shaded region:
P = 1256/1600 = 0.785 or 78.5%Answer:
78.5%
Step-by-step explanation:
We can find the area of both shapes then divide to find the probability.
Square area:
40 * 40 = 1600ft²
Circle area with diameter [ 1/4πd² ]:
1/4π(40)²
1/4π(1600)
0.785(1600)
1,256
Now divide both areas to find the probability.
1256/1600 = 0.785
0.785 * 100% = 78.5%
Best of Luck!
