Two geometry questions in the attached photos - If I have a line, do I have a plane? & If I have three points, do I always have a plane?
Answers
Answer:
18) A: only if you have an additional point not on the line.
19) D: No, because all the points may be on the same line.
Step-by-step explanation:
There are basically 4 ways we can determine a plane and they are;
- When we have three non - collinear points: What this means is that if we have three points that are not on one line, then it means that only one particular plane can pass through those points.
- When we have a line and a point that's not on the line
- When we have two lines that intersect each other.
- When we have two lines that are parallel to each other.
From the four conditions above, we can now answer the question;
18) You can only have a plane if there is an additional point not on the line.
Option A
19) Having just three points may not always be sufficient to have a plane because it's possible that the three points may be on the same line which is not a condition for a plane. Thus, option D is correct.

Answer:
17 meters
Step-by-step explanation:
Plug x=30 into the equation H(x) = 11 + 0.2x
H(30) = 11 + 0.2 * 30
H(30) = 11 + 6
H(30) = 17
Thus, the answer is 17 meters.

Answer:
Proved , since LHS= RHS
Step-by-step explanation:
We need to prove the given expression ,
=> 1 + cos x / 1 + sec x = cos x
Simplifying LHS.=> 1 + cos (x) / 1 + sec (x)
=> 1 + cos (x) / 1 + 1/cos (x)
=> 1 + cos (x) ÷ 1 + cos(x) / cos (x)
=> 1 + cos (x) × cos(x) / { 1 + cos (x) }
1 + cos (x) gets cancelled . So we are finally left out with ,=> cos (x)

Answer:
True, false, true
Step-by-step explanation:
Because the minimum value of f(x) is -1, and the minimum value of g(x) us -25. It comes only once.
Roots are the points on the x - axis or when the x is 0. The roots of f(x) are positive.
f(0) means when x is 0, so f(0) = 3 or 5, and g(0) = -24
A polygon has vertices at (4, 1), (4,7), (10, 7) and (10, 1). How does the perimeter of
the polygon change if each coordinate is multiplied by 3?
Answers
The perimeter goes from 24 to 72
24*3 = 72
==========================================================
Explanation:
I recommend plotting the four points on the same xy grid system. Connect the points with segments to form a rectangle. This rectangle is also a square. You should find that each side of the square is 6 units long, so the perimeter is 4*6 = 24 units.
If we multiply each coordinate by 3, then that will make each side length 3 times longer than before. That means each side is now 6*3 = 18 units long. The perimeter is 4*18 = 72 units.
Note how the jump from 24 to 72 is "times 3". Therefore, the scale factor of 3 will make the new perimeter 3 times longer compared to the old perimeter.
Find the missing dimension of the triangle. Area =14ft^2, height =6ft, base= ? Find the base.
Answers
Answer: b = 14/3 = 4.667 feet
The decimal value is approximate. In reality the 6's go on forever. Round that however you need to.
================================================
Work Shown:
b = unknown base
h = height = 6 ft
A = area = 14 sq ft
A = b*h/2
14 = b*6/2
14 = b*3
14 = 3b
3b = 14
b = 14/3
This approximates to 14/3 = 4.667 ft
