A particle travels in a circle around a fixed point at 16 revolutions per minute. The linear velocity of the particle is 240
inches per minute.
What is the distance, in inches, between the particle and the fixed point?
Answers
Answer:
15 inches
Step-by-step explanation:
We are given;
Linear velocity; V = 240 in/min
ω = 16 rev/min
Now, in circular motion, formula for linear velocity is;
V = ωr
Where ω is angular velocity and r is radius which is the distance between the object and the fixed point.
Thus;
240 = 16r
r = 240/16
r = 15 inches

The head track coach for PCTVS has a big track meet coming up. He knows that his biggest rival is Clifton and the entire track meet will come down to one event, the 100 meter relay race. The relay race is comprised of 4 runners from each team who run 100 meters each. The track coach has been working on his projections for the race and knows it will come down to the last leg of the race. He is having difficulty with his algebra skills, so he has asked the Honors classes at PCTI to help him make a projection for the race. He knows that on the last leg of the race, his runner will be leading the race. PCTVS's runner runs at a speed of 10.1 meters per second. Clifton's runner runs at a rate of 10.9 meters per second and will start the last leg of the race 0.8 seconds behind the runner from PCTVS. Will PCTVS win the relay race?

16. Definition 3: Two lines which intersect
Proof:
I need help with the proof :)
Answers
Answer:
14. Three points tat are not collinear
Three points that are not colinear consist of a line and a third point, therefore, joining all three points form a flat figure having a length and a width which is a two-dimensional flat figure or a plane
15. A line and a point not lying on the line
Like the example above, the joining of the points results in a two dimensional figure having a length and a width also known as a planar surface
16. Two lines which intersect at a point
Given two lines that intersect at a point, joining the other end point of the two lines results in the forming of a flat figure, that can be described in two dimensions also known as a planar surface or plane
Step-by-step explanation:
A plane in mathematics is a flat surface that has only two dimensions and extends infinitely in all directions

Answer:
[tex]\boxed {x = \frac{17}{10}}[/tex]
Step-by-step explanation:
Solve for the value of [tex]x[/tex]:
[tex]3(5 - x) = 7x - 2[/tex]
-Use Distributive Property:
[tex]3(5 - x) = 7x - 2[/tex]
[tex]15 - 3x = 7x - 2[/tex]
-Take [tex]7x[/tex] and subtract it from [tex]-3x[/tex]:
[tex]15 - 3x - 7x = 7x - 7x - 2[/tex]
[tex]15 - 10x = -2[/tex]
-Subtract [tex]15[/tex] to both sides:
[tex]15 - 15 - 10x = -2 - 15[/tex]
[tex]-10x = -17[/tex]
-Divide bot sides by [tex]-10[/tex]:
[tex]\frac{-10x}{-10} = \frac{-17}{-10}[/tex]
[tex]\boxed {x = \frac{17}{10}}[/tex]
So, the value of [tex]x[/tex] is [tex]\frac{17}{10}[/tex].

Venus Waldo reviewed her account statement and wanted to verify that the interest amount was correct. Her new balance was $12,098.12 and her previous balance was $9,043.20. She had deposited $3,298.45 and withdrawn $300.00. Find the interest earned on Venus' savings account.
Answers
Answer:
The interest on the savings account is $46.47
Step-by-step explanation:
Here, we want to know the interest earned on the savings account.
The difference between the new and previous balance will be; 12,098.12 - 9,053.20 = $3,044.92
The difference between amount deposited and amount withdrawn is 3,298.45 - 300 = 2,998.45
This is the amount that is supposed to be on the account without interest
So the interest earned would be; 3044.92 - 2,998.45 = $46.47

Questions 7 and 8 multiple choice
Answers
Problem 7
Answer: Choice A) 7--------------------------------------
Work Shown:
p(x) = x^4+x^3-kx-x+6
If (x-2) is a factor of p(x), then x = 2 is a root of p(x). This is a special case of the remainder theorem.
This means p(2) = 0
Replace every x with 2 and solve for k
p(x) = x^4+x^3-kx^2-x+6
p(2) = 2^4+2^3-k(2)^2-2+6
p(2) = 16+8-4k-2+6
p(2) = 28-4k
0 = 28-4k .... replace p(2) with 0
4k = 28
k = 28/4
k = 7
The polynomial
p(x) = x^4+x^3-7x^2-x+6
has the factor (x-2)
============================================
Problem 8
Answer: D) 40--------------------------------------
Work Shown:
Check out the diagram below to see the synthetic division table. We're after the remainder which is highlighted in yellow.
An alternative is to use direct substitution
p(x) = 2x^4+4x^3-x^2-5
p(-3) = 2(-3)^4+4(-3)^3-(-3)^2-5 ... replace every x with -3
p(-3) = 2(81)+4(-27)-9-5
p(-3) = 162-108-9-5
p(-3) = 40
This helps confirm we got the right remainder and the right answer.

Chanelle selects a marble from a container and then returns it to the container. When she does this 3 times, the probability of choosing a red marble all 3 times is 1/216. Based on this information, what is the probability of Chanelle choosing a red marble the first time she selects a marble?
Answers
Answer:
1 ÷ 6
Step-by-step explanation:
Let us assume the probability of the red marble for selecting it first time be x
And, it is to be done 3 times
that means
= 1 ÷ x × 1 ÷ x × 1 ÷ x
This equivalent to = 1 ÷ 216
And the 216 could be calculated by multiplied 6 3 times i.e.
= 6 × 6 × 6
= 216
So, the probability for selecting it for a first time is
= 1 ÷ 6

(a) A square has a perimeter or 32 cm. What is the length of each side?
cm
(D) A square has an area of 144 m². What is the length of each side?
Answers
Answer:
A) 8cm
B) 12cm
Step-by-step explanation:
A) Perimeter = 4 × L
where L is the length of the sides
32 = 4 × L
32/4 = L
L = 8cm
B) Area = L^2
144 = L^2
L = square root of 144
L = 12cm
a)
The length of each side is 8 cm.
d)
The length of each side is 12 m.
What is a square?A square is a two-dimensional figure that has four sides and all four sides are equal.
The area of a square is given as side².
We have,
The perimeter of the square = 32 cm
Area of the square = 144 m²
Now,
Perimeter = 32 cm
4 Side = 32 cm
Side = 32 /4
Side = 8 cm
Area = 144 m²
Side² = 144
Side = 12 m
Thus,
The length of the side is 8 cm.
The length of the side is 12 m.
