If two points are in a plane, then the line containing those points lies entirely in the plane True or false
Answer: True
Step-by-step explanation:
True, if two points are in a plane, then the line joining the two points lies entirely in the plane.
Discussion:
For instance, if two points A and B lie in a plane x-y, We can conclude that the line AB also lies in the plane x-y.
This therefore means that; Irrespective of whether the points are in represented in 2 or 3 dimensions, the line joining them lies within the plane in discuss.

2. A supermarket display consists of boxes of cereal. The bottom row has 33 boxes. Each row has five fewer boxes than the row below it. The display has six rows.
(a) Write and use a function to determine how many boxes are in the top row. Show your work.
(b) Use the appropriate formula to determine the number of boxes in the entire display. Show your work
Answer:
a. f(x)=58-5(x-1); there are 58 boxes in the top row.
b. 273 boxes
Step-by-step explanation:
There are 33 boxes at the bottom row, and there are 5 fewer boxes than the row before it meaning that each row above the bottom row has five more boxes than the one below it.
Basically:
bottom row (with 33 boxes) -->5th row-->4th row-->3rd row-->2nd row-->1st row
each arrow adds five boxes, so if you add 5 boxes for each arrow, there is a total of 58 boxes on the 1st row.
check:
2nd row:
f(x)=58-5(x-1)
f(2)=58-5(2-1)
f(2)=58-5(1)
f(2)=58-5
f(2)=53
and we know that 58 (first row)-5=53 (second row; has to have five fewer boxes) so the function works.
now we can use the formula to find the other row values:
3rd row:
f(x)=58-5(x-1)
f(3)=58-5(3-1)
f(3)=58-5(2)
f(3)=58-10
f(3)=48
4th row:
f(x)=58-5(x-1)
f(4)=58-5(4-1)
f(4)=58-5(3)
f(4)=58-15
f(4)=43
5th row:
f(x)=58-5(x-1)
f(5)=58-5(5-1)
f(5)=58-5(4)
f(5)=58-20
f(5)=38
so, we have the row values from top to bottom:
58, 53, 48, 43, 38, 33
now we just have to add them up, giving us 273 boxes in total.
18 = r/3 what is r???
Answer:
54
Step-by-step explanation:
r/3 = 18
r/3 * 3 = 18 * 3
r = 54
Answer:
54
Step-by-step explanation:
multiplication is the opposite of division so you can do 18*3=54 and you can check that by dividing 54 and 3 and the answer is 18
What are the first 3 terms in. t(n)=-2n+7
Answer:
The first 3 terms of the sequence [tex]t(n)=-2n+7[/tex] are:
[tex]5, 3, 1[/tex]
Step-by-step explanation:
Given the sequence
[tex]t(n)=-2n+7[/tex]
Here [tex]n[/tex] represents any term number in the sequence
Determining the first term
substitute n = 1 in the sequence to determine the first term
[tex]t(n)=-2n+7[/tex]
[tex]t(1)=-2(1)+7[/tex]
[tex]t(1)=-2+7[/tex]
[tex]t(1) = 5[/tex]
Determining the 2nd term
substitute n = 2 in the sequence to determine the 2nd term
[tex]t(n)=-2n+7[/tex]
[tex]t(2) = -2(2) + 7[/tex]
[tex]t(2) = -4 + 7[/tex]
[tex]t(2) = 3[/tex]
Determining the 3rd term
substitute n = 3 in the sequence to determine the 3rd term
[tex]t(n)=-2n+7[/tex]
[tex]t(3) = -2(3) + 7[/tex]
[tex]t(3) = -6 + 7[/tex]
[tex]t(3) = 1[/tex]
Therefore, the first 3 terms of the sequence [tex]t(n)=-2n+7[/tex] are:
[tex]5, 3, 1[/tex]

vertical angles and right angles in a quadrilateral
step by step please !
Answer:
Step-by-step explanation:
Since the sum of all interior angles of a triangle is 180 degrees, we are able to derive the answer of what x (m<1 in this case) measures.
For example, in number 1, you can do
m<1 = 180 - 94 - 45
For the 2nd one, the tick marks show that the highlighted angles measure the same.
So, it would be (180-58)/2 = m<1
Finally, for the third one, there is a right angle, meaning that it measures 90 degrees
Therefore, 180-90-77 = m<1

The sum of the first n consecutive even numbers can be found using S=n^2+n where n ≥ 2. What is the value of n when the sum is 210?
Answer:
n = 14Step-by-step explanation:
Given the sum of the first n consecutive even numbers expressed as
S=n^2+n where n ≥ 2.
If S = 210, then;
210 = n² + n
n² + n - 210 = 0
Factorize
n = -1±√1²-4(-210)/2
n = -1±√1+840/2
n = -1±√841/2
n = -1±29/2
n = -1+29/2 and -1-29/2
n = 28/2 and -30/2
n = 14 and -15
Since n ≥ 2, hence the required value of n is 14
Número que tiene dos centenas, cero decenas y nueve unidades
Answer: 209
Step-by-step explanation:
Si un número tiene 2 centenas, significa 200. Si tiene 0 decenas, entonces debería haber un 0 en el lugar de las decenas. Si un número tiene 9 unos, entonces debería haber un 9 en el lugar de las unidades. Debido a esto, el número con Número que tiene dos centenas, cero decenas y nueve unidades es 209.
English answer:
If a number has 2 hundreds, it means 200, and there should be a 2 in the hundreds place. If it has 0 tens, then there should be a 0 in the tens place. If a number has 9 ones, then there should be a 9 in the ones place. Because of this, the number with Number that has two hundreds, zero tens, and nine ones is 209.
Use the inequality sign to show which situation has the greater unit rate.

Isolate the variable by dividing each side by factors that don't contain the variable.
A car moving on a highway covers the first 400.0 m in 18.0s and then covers the next 250.0 m in 24.0 s.
What is the average speed of the car?
Answer: 15.48 m/s
Step-by-step explanation:
The following information can be gotten from the question:
Total distance covered by the car will be:
= 400m + 250m
= 650m
Total time taken = 18.0s + 24.0s = 42s
Average speed = Distance/Time
= 650/42
= 15.48 m/s
