Answer:
1. Intersecting lines are always coplanar
2. Two planes never intersect in exactly one point
3. Three points are always coplanar
4. A plane containing two points of a line always contains the entire line
5. Four points are sometimes coplanar
6. Two lines never meet in more than one point.
7. Two skew lines are never coplanar
8. Line TQ and Line QT are always the same line.
Step-by-step explanation:
Note: Coplanar means "In the same plane"
1. Each line exist in many planes. But different lines must share at least one plane for them to intersect. That is why intersecting lines are always coplanar.
2. Two planes never intersect at exactly one point because only lines intersect at a point. Planes can only intersect along a line.
3.Three points are always coplanar because in geometry, a group of points are coplanar because there is a geometric plane that they all lie on.
4. A plane containing two points of a line always contains the entire line. Yes
5. Four points are only sometimes coplanar because there is a probability that they may all not lie on the same plane
6. Two lines never meet in more than one point because lines are basically straight and cannot bend over to intersect at another point
7. Two skew lines are never coplanar because skews lines are lines that do not intersect and are never parallel.
8. Line TQ and Line QT are always the same line because a line is straight and extends from one point to the other. So, if a line is labelled TQ calling it QT means the same thing
At a model rocket competition, Mrs. Jennings launches a rocket is launched upward
from the ground with an initial velocity of 138 feet per second.
The formula for vertical motion is
h(t) = 0.5at? + vt +s, where the gravitational constant, a, is -32 feet per second squared, v
is the initial velocity, and s is the initial height. Time t is measured in seconds, velocity
v is measured in feet per second, and heights h and s are measured in feet.
Write the function that describes the height, h in feet, of the rocket l seconds into
launch
Answer:
The function that describes the height, h in feet, of the rocket, t seconds into launch is h = -16·t² + 138·t
Step-by-step explanation:
The given parameters are;
The initial velocity of the rocket, v = 138 feet per second
The vertical motion formula = h(t) = 0.5·a·t² + v·t + s
The gravitational constant, a = -32 ft./s²
s = The initial height of the rocket
Therefore, he have;
The height of the rocket, t seconds seconds into launch is given as follows;
Height = h = h(t) - s = 0.5·a·t² + v·t
Substituting the known values gives;
h(t) - s = 0.5 × (-32) × t² + 138 × t = -16·t² + 138·t
h = -16·t² + 138·t
The function that describes the height, h in feet, of the rocket, t seconds into launch is h = -16·t² + 138·t.

A figure has an area of 64 unit square which describes the area of the figure after a dilation with a scale factor of 3/2
Answer:
It's 144 units^2
Step-by-step explanation:
You have to take your 3/2 and square it, turning it to 9/4 and multiply that by 64, which gives you 144.
Cami starts with $7 and saves $13 each week.
Maggie starts with $11 and saves $13 each week. After how many weeks will Cami and Margaret have the same amount of
money?
Answer:
No matter how many weeks pass, they will never have the same amount of money. This is because their rate of change is the same. If Cami made more money per week than Maggie, then she would eventually be able to catch up and have the same amount of money as Maggie.

Consider a parabola P that is congruent to y=x^2, opens upward, and has vertex (0,0). Find the equation of a new parabola that results if P is reflected in the x-axis, and translated 1 unit to the left and 3 units up.
9514 1404 393
Answer:
y = -(x+1)^2 +3
Step-by-step explanation:
Translating f(x) left by 1 unit replaces x with x+1.
Translating f(x) up by 3 units replaces f(x) with f(x)+3.
Reflecting f(x) over the x-axis replaces f(x) with -f(x).
__
When y = x^2 is reflected over the x-axis, it becomes ...
y = -x^2
When y = -x^2 is translated 1 unit left, it becomes ...
y = -(x +1)^2
When y = -(x+1)^2 is translated 3 units up, it becomes ...
y = -(x +1)^2 +3

Scientists have found that the relationship between the area of an island and the number of species can be modeled approximately by S=-3.404+103.2ln(A) S=−3.404+103.2ln(A), where AA is the area in km^2km 2 and SS is the number of species.
Answer:
[tex]A=e^{(S+3.404/103.2)[/tex]
Step-by-step explanation:
Step one:
we are told that the relationship between the number of species and the island area is given as
[tex]S=-3.404+103.2ln(A)[/tex]-----------------1
based on any given value for either area or number of species, we can find the other.
say we want to find the land area for a given amount of specie
Step two:
we first make area A subject of the formula.
[tex]S=-3.404+103.2ln(A)[/tex]
let us isolate [tex]ln(A)[/tex]
[tex]S + 3.404 = 103.2ln(A)[/tex]
Divide both sides by 103.2 we have
[tex](S + 3.404)/103.2 = ln(A)[/tex]
Now, exponentiate both sides using the base e.
[tex]A=e^{(S+3.404/103.2)[/tex]----------------2
for a given value of "S" we can find the area A based on the above expression.

10 divided by 2 would be 5 because it pretty much splits it in equal parts like this if you do each friend get 1 cup of water there is 9 liters so what you do it give each 3 liters of water and that's 9 divided by 3 so you split 3 parts into 9
Answer:
First of how many friends are there and if each freind get one why are you giving them three and did you count yourself as well
Step-by-step explanation:
A 68-year old retiree has a pension savings of $43,000, a 401k of $75,000, and an IRA account of $62,000. Before 2008, he had 2% more cash in the pension, 12% more in the IRA, and −1% in the 401k. He wants to take out 2% from each account before he turns 72, which will cost him a penalty of an extra 3% from the current total amount in his pension, 4% from the 401k, and 6% from the IRA. What is the highest amount that will be taken from a single account, including the penalty, if the retiree takes the money out now from each?
Answer:
The answer is the IRA
Step-by-step explanation:
If he takes out 2% from each account, the highest penalty will be for the IRA account which is, 6% of 62,000 is $3,720. He will also take 2% of that 62,000 which will be $1,240. The total will be $4,960.
For the 401k account the withdrawal is $1,500 and the penalty is $3,000. That is $460 less than the IRA account.
I hope this answer helps.

Suppose Jerome reads the following numbers of pages each day. Will he meet his goal of reading at least 85 pages by the end of the day Friday?
Answer:
Step-by-step explanation:
Jerome has already read 50 pages of a novel and read p pages each day from Monday to Friday.
If Jerome read at least 85 pages by the end of Friday, inequality will be,
50 + 5p ≥ 85
If Jerome reads 6 pages each day,
For p = 6,
Inequality will be,
50 + 5(6) ≥ 85
80 ≥ 85
It's not true.
Therefore, he will not meet his goal.
If p = 7,
Inequality will be,
50 + 5(7) ≥ 85
85 ≥ 85
It's true.
Therefore, he will meet his goal.
If p = 8,
Inequality will be,
50 + 5(8) ≥ 85
90 ≥ 85
It's true.
Therefore, he will meet his goal.

Answer:
x=36°
y=144°
Step-by-step explanation:
y is the corresponding angle of angle 144° and since corresponding angles are always congruent y=144°
x is the same side interior angle of angle 144° and since same side interior angles are also supplementary angles that add up to 180° x=36°
180°-144°=36°
hopefully this helps :)
