Answers
Step-by-step explanation:
sorry, I cannot draw here.
anyway, "collinear" simply means the points are on the same line. "coplanar" simply means they are on the same plane (a 2-dimensional area in the 3-dimensional space).
J, U : CL (they are on the same line, clearly visible)
L, J : N (J is above the drawn plane of L)
F, U. L : CP (all 3 are on the same plane)
O, U, J : N (they are not on anything together)
L, Y, O : CP (all 3 on the same plane, L is a corner point where 2 planes meet and is therefore actually on both planes).
but FYI - 2 points are always defining a line, and 3 points are always defining a plane, even if the line or plane is not drawn in the graphics.
so, if we want to take it really fully literally, then L, J is still CL, and O, U, J is CP. just not for any line or plane drawn in the graphic. their, I don't think your teacher wants to understand it that way (which is why I answered as I answered), but formally that's what it should be ...
TK and AK are intersecting (at the joined point K).
AL and TO are parallel.
OE and OT are perpendicular (cross each other at a right angle = 90°).
LE, LB, LO are concurrent (they all intersect in one point : L).
AT and LE are skew lines (they do not intersect each other, and they are not parallel, so, they simply go "wildly criss-cross" through space relative to reach other).
for the illustration :
Y E S
draw a line, make 3 dots on the line and mark the dots Y, E and S. and they are automatically collinear. it's that easy.
MA TH
the symbol between means "right-angled".
so, draw 2 lines that are right-angled to each other (remember, 90°). make 2 dots on each line. mark the dots M and A on one line, and T and H on the other line.
mark the angle between the lines with the little square as in the graphic above to indicate the 90°.
q p r
the symbols between mean "parallel".
so, simply draw 3 parallel lines and mark them q, p and r.
make a little cross mark like " on each of them (that indicates they are parallel).

Carly’s bake shop requires 3.5 hours of labor to produce one cake and 2 hours of labor to produce one pie, and the shop has a maximum of 70 total labor hours available. If X1 represents number of cakes and X2 represents number of pies, how would this constraint be written?
Answers
Step-by-step explanation:
3.5 hours for 1 cake means 3.5 hours per cake.
similar : 2 hours for 1 pie means 2 hours per pie.
so, if there are e.g. 3 pies, they take 3×2 = 6 hours.
therefore the general constraint is
3.5x1 + 2x2 <= 70
I think the names "x1" and "x2" are confusing when writing this inequality.
I prefer to use x and y.
and then it would look like
3.5x + 2y <= 70

Refer to the attachment for solution !
The trigonometry identity [tex]\frac{ \tan(a) }{1 - \cot(a) } + \frac{ \cot(a) }{1 - \tan(a) } = \sec(a) \csc(a) + 1[/tex] is true
The trigonometry identity is given as:
[tex]\frac{ \tan(a) }{1 - \cot(a) } + \frac{ \cot(a) }{1 - \tan(a) } = \sec(a) \csc(a) + 1[/tex]
Express cot(a) as 1/tan(a)
[tex]\frac{ \tan(a) }{1 - \frac{1}{\tan(a)} } + \frac{ \frac{1}{\tan(a)} }{1 - \tan(a) } = \sec(a) \csc(a) + 1[/tex]
Take LCM
[tex]\frac{ \tan(a) }{ \frac{\tan(a) - 1}{\tan(a)} } + \frac{ \frac{1}{\tan(a)} }{1 - \tan(a) } = \sec(a) \csc(a) + 1[/tex]
Simplify the expression
[tex]\frac{ \tan^2(a) }{\tan(a) - 1 } + \frac{ \frac{1}{\tan(a)} }{1 - \tan(a) } = \sec(a) \csc(a) + 1[/tex]
Further, simplify
[tex]\frac{ \tan^2(a) }{\tan(a) - 1 } + \frac{1}{\tan(a)(1 - \tan(a)} = \sec(a) \csc(a) + 1[/tex]
Rewrite as:
[tex]\frac{ \tan^2(a) }{\tan(a) - 1 } - \frac{1}{\tan(a)(\tan(a) -1) } = \sec(a) \csc(a) + 1[/tex]
Take LCM
[tex]\frac{\tan^3(a) - 1}{\tan(a)(\tan(a) -1) } = \sec(a) \csc(a) + 1[/tex]
Expand the numerator
[tex]\frac{(\tan(a) - 1)(\tan^2(a) + \tan(a) + 1)}{\tan(a)(\tan(a) -1) } = \sec(a) \csc(a) + 1[/tex]
Cancel out the common factors
[tex]\frac{\tan^2(a) + \tan(a) + 1}{\tan(a) } = \sec(a) \csc(a) + 1[/tex]
Simplify
[tex]\tan(a) + 1 + \cot(a) = \sec(a) \csc(a) + 1[/tex]
Rewrite as:
[tex]\tan(a) + \cot(a)+ 1 = \sec(a) \csc(a) + 1[/tex]
Rewrite as:
[tex]\frac{\sin(a)}{\cos(a)} + \frac{\cos(a)}{\sin(a)}+ 1 = \sec(a) \csc(a) + 1[/tex]
Take LCM
[tex]\frac{\sin^2(a)+\cos^2(a)}{\cos(a)\sin(a)}+ 1 = \sec(a) \csc(a) + 1[/tex]
Express the numerator as 1
[tex]\frac{1}{\cos(a)\sin(a)}+ 1 = \sec(a) \csc(a) + 1[/tex]
Simplify
[tex]\sec(a) \csc(a) + 1 = \sec(a) \csc(a) + 1[/tex]
Hence, the trigonometry identity [tex]\frac{ \tan(a) }{1 - \cot(a) } + \frac{ \cot(a) }{1 - \tan(a) } = \sec(a) \csc(a) + 1[/tex] has been proved

A) 1/3
B) 1/2
C) 2
D) 3
Answers
Answer:
The answer is C.
Answer: B) 1/2
How to get that answer:
The larger triangle (preimage) has its vertical side of 6 units.
For the smaller triangle (image), the vertical side is 3 units.
The scale factor is image/preimage = 3/6 = 1/2
Meaning that the smaller triangle's side lengths are 1/2 of the larger triangle's side lengths.

The basement for a house is being excavated and the rectangular hole measures 11m by 14,5m by 4m. The soil is being hauled away in a dump truck which has an open-box bed of 4m by 3m by 200 cm . The truck Cant be overloaded at any time. How many trips will the dump truck have to make a haul away all of the soil.
Answers
Using volume of a rectangular prism, it is found that the dump truck will have to make 266 trips to haul away all of the soil.
What is the volume of a rectangular prism?The volume of a rectangular prism of length l, width w and height h is given by:
[tex]V = lwh[/tex]
In this problem, both the hole and the open-box bed are rectangular, hence the number of trips is the ratio between the volumes of the hole and of the open-box bed.
What is the volume of the volume of the hole?The dimensions in meters are [tex]l = 11, w = 14.5, h = 4[/tex], hence:
[tex]V_h = 11(14.5)(4) = 638[/tex]
What is the volume of the volume of the open-box?The dimensions in meters are [tex]l = 4, w = 3, h = 0.2[/tex], hence:
[tex]V_b = 4(3)(0.2) = 2.4[/tex]
What is the ratio of the volumes?It's their division, hence:
[tex]r = \frac{V_h}{V_b} = \frac{638}{2.4} = 265.8[/tex]

Explanation:
The adjacent angles of a parallelogram always add to 180
D+E = 180
(9x+15)+(6x) = 180
15x+15 = 180
15x = 180-15
15x = 165
x = 165/15
x = 11
Then we use this to find angle D
D = 9x+15 = 9*11+15 = 99+15 = 114
note that
E = 6x = 6*11 = 66
and
D+E = 114+66 = 180
to help confirm our answer.
Answer:
114
Angles in Quadrilateral adds to 360
2 x (9x+15) + 2 x (6x) = 360
18x + 30 +12x =360
30x + 30 = 360
-30
30x =330
÷30
x=11
Substitute value of x into Angle D
9x+15 will be 9 x 11 + 15 = 114
Thus, the answer is 114

If employment is expected to increase by 14.8% between 01/2009 and 01/2016 and the employees number 19, 100 in 01/2009, how many total employees will there be in 01/2016?
Answers
Based on the rate of increase, the number of employees that will be there in 2016 is 21,927 people.
Number of employees in 2016This can be calculated by the formula:
= Employees in 2009 x ( 1 + rate of increase)
Solving gives
= 19,100 x (1 + 14.8%)

Two grapefruits and three oranges cost $1.95. Three grapefruits and two oranges cost $2.05.
What are the costs of one grapefruit and one orange?
Answers
Answer:
one orange costs $0.35 and one grapefruit costs $0.45Step-by-step explanation:
let grapefruits be g , let oranges be o
so first equation:
→2g + 3o = $1.95
→g = ($1.95 - 3o)/2
so second equation:
→ 3g + 2o = $2.05
→ g = ($2.05 - 2o)/3
Solving simultaneously:
→ ($2.05 - 2o)/3 = ($1.95 - 3o)/2
→ 2($2.05 - 2o) = 3($1.95 - 3o)
→ 4.1 - 4o = 5.85 - 9o
→ - 4o + 9o = 5.85 - 4.1
→ 5o = 1.75
→ o = $0.35
Therefore one orange costs $0.35
Then one grapefruit costs g → ($1.95 - 3o)/2
→ g = ($1.95 - 3(0.35))/2
→ g = 0.45
Therefore one grapefruit costs $0.45
