At a space exploration center, astronauts are training on a human centrifuge that has a diameter of 70 feet.
a. The centrifuge makes 72 complete revolutions in 2 minutes. What is the angular velocity of the centrifuge in radians per second? What distance does an astronaut travel around the center each second?
b. Acceleration is the rate of change of velocity with time. An object
moving at a constant velocity v in circular motion with a radius of r 2
has an acceleration a of a = _v_. What is the astronaut’s acceleration? r
(Note that the acceleration will have units of feet per second squared.)
c. One“g”istheaccelerationcausedonEarth’ssurfacebygravity.This acceleration is what gives you your weight. Some roller coasters can produce an acceleration in a tight loop of 5 or even 6 g’s. Earth’s gravity produces an acceleration of 32 ft/s2. How many g’s is the astronaut experiencing in the centrifuge?
The astronaut is experiencing approximately 6.21 g's in the centrifuge.
a. To find the angular velocity of the centrifuge in radians per second, we first need to convert the number of revolutions per minute to revolutions per second. Since there are 60 seconds in a minute, the angular velocity (ω) can be calculated as follows:
Angular velocity (ω) = (Number of revolutions per minute) / 60
Given that the centrifuge makes 72 complete revolutions in 2 minutes:
ω = 72 / 2 / 60 = 1.2 revolutions per second
Next, to find the distance an astronaut travels around the center each second, we can use the formula for the circumference of a circle:
Circumference = π × diameter
Circumference = π × 70 feet
Circumference ≈ 220 feet
Distance traveled each second = Circumference × ω
Distance traveled each second = 220 feet × 1.2 revolutions per second ≈ 264 feet
So, the angular velocity of the centrifuge is approximately 1.2 radians per second, and an astronaut travels around the center approximately 264 feet each second.
b. The acceleration (a) of an object moving in circular motion with a constant velocity (v) and a radius (r) is given by the formula:
[tex]a = v^2 / r[/tex]
Since the astronaut is moving at a constant velocity around the center of the centrifuge, we can use the same formula to find their acceleration. The velocity of the astronaut is the distance traveled each second (264 feet) and the radius of the centrifuge is half of its diameter (70 feet / 2 = 35 feet):
Acceleration (a) = (264 feet per second)^2 / 35 feet ≈ 198.86 feet per second squared
So, the astronaut's acceleration is approximately 198.86 feet per second squared.
c. To find how many g's the astronaut is experiencing in the centrifuge, we need to compare their acceleration with the acceleration due to gravity on Earth (32 feet per second squared). One g is equivalent to the acceleration due to gravity.
Number of g's = Acceleration (astronaut) / Acceleration due to gravity on Earth
Number of g's = 198.86 feet per second squared / 32 feet per second squared ≈ 6.21 g's
So, the astronaut is experiencing approximately 6.21 g's in the centrifuge.

The sum of the two digits of a number is 16. The number formed by reversing the digits is 18 more than the original
number. Determine the original number.
Let t = the tens digit, u = the units digit, and u + t = 16. Which of the following equations would complete the system?
Answer:
10u+t=18+10t+u
(If this doesn't match one of the equations, please post your options so I can put it in the form of one of your options.)
Step-by-step explanation:
Let there be a number [tu] where t is the tens and u is ones digit.
t+u=16.
Now we reverse the number [ut] is 8 more than [tu].
[ut]=18+[tu]
So [ut]=10u+t because u is the tens and t is the ones digit
and [tu]=10t+u because t is the tens and u is the ones digit.
The equation you are looking for is
10u+t=18+10t+u.
Let's solve it just for fun:
Subtract u on both sids:
9u+t=18+10t
Subtract 10t on both sides:
9u-9t=18
Divide both sides by 9:
u-t=2
The system is:
u-t=2
u+t=16
--------------add!
2u =18
u=9
If u=9 and u+t=16, then t=7.
To the original number is 79.
The new number is 97 (is this 18 more than the other; yep).

A cleaner recommends mixing 1 1/2 cup of cleaner for every 12 cups of water. What is the ratio of cleaner to water.
Answer: [tex]\frac{1}{8}[/tex] or [tex]1:8[/tex]
Step-by-step explanation:
First, you can convert the mixed number [tex]1\ \frac{1}{2}[/tex] into a decimal number. To do this, you need to divide the numerator (which is 1) by the denominator (which is 2) of the fraction:
[tex]\frac{1}{2}=0.5[/tex]
Now you must add 0.5 to the whole number part. Then:
[tex]1+0.5=1.5[/tex]
In order to find the ratio of cleaner to water, you must divide 1.5 cups of cleaner by 12 cups of water.
Therefore, the ratio is:
[tex]ratio=\frac{1.5}{12}=\frac{1}{8}[/tex] or [tex]1:8[/tex]
If two angles are complementary and one of them is 13º, what is the measure of the other angle?
A.73
B.77
C.63
D.13
Final answer:
The measure of the other angle that is complementary to a 13º angle is 77º.
Explanation:
If two angles are complementary, it means they add up to 90 degrees. In this case, one angle is given as 13º. To find the measure of the other angle, we subtract the given angle from 90º because complementary angles sum up to 90 degrees.
So, if we let x represent the measure of the other angle, the equation becomes:
13° + x = 90°
To find x, we subtract 13 from both sides:
The calculation would be:
90º - 13º = 77º.
Therefore, the measure of the other angle is 77º.
Hence, the correct answer is:

Step-by-step explanation:
Write the equation of the line that passes through the points (7, –4) and (–1, 3), first in point-slope form, and then in slope-intercept form.
Final answer:
The equation of the line through (7, -4) and (-1, 3) has a slope of -7/8. It can be written in a point-slope form as y + 4 = -7/8(x - 7), and in slope-intercept form as y = -7/8x + 25/8.
Explanation:
To write the equation of the line that passes through the points (7, –4) and (–1, 3), the first step is to find the slope of the line. The slope (m) is given by the rise over run, which is the change in y divided by the change in x:
m = (3 - (-4)) / (-1 - 7) = 7 / -8 = -7/8Now that we have the slope, we can use the point-slope form which is given by the formula:
y - y1 = m(x - x1)We can choose one of the points for x1 and y1; let's use (7, -4):
y - (-4) = -7/8(x - 7)Therefore, the point-slope form of the line is:
y + 4 = -7/8(x - 7)Now, to convert this into the slope-intercept form (y = mx + b), we just solve for y:
y = -7/8x + 7/8 × 7 - 4After simplifying the constant term:
y = -7/8x + 25/8The slope-intercept form is y = -7/8x + 25/8, where -7/8 is the slope and 25/8 is the y-intercept.

A wooden pole is 20 m high. A steel wire is tied to the top of the pole and fixed to the ground. If the angle made by the
wire with the ground is 60°, find the length of the steel wire.
Answer:
23.09 meters.
Step-by-step explanation:
Sin(60) = opposite / hypotenuse = pole / steel wire
pole = 20 m
angle = 60 degrees.
sin(60) = 20/ hypotenuse multiply both sides by the hypotenuse
hypotenuse * sin(60) = 20 divide by sin(60)
hypotenuse = 20 / 0.866 do the division
hypotenuse = 23.09
The steel wire = 23.09 meters.

Answer:
(L + 10)/(L + 16) = 0.8
Step-by-step explanation:
She needs to answer L more questions to get a grade of 80%.
When she answers L more questions correctly, she will have answered L + 10 questions correctly.
The total number of questions will be L + 16.
L + 10 must be 80% of L + 16
(L + 10)/(L + 16) = 0.8
Cheryl must use the equation 0.80 = (10 + I) / (16 + I) to determine how many consecutive questions she needs to answer correctly to reach her goal of 80% accuracy on her test.
Cheryl has answered 16 questions on her online test with 10 correct responses. To achieve her goal of 80% accuracy, she must determine how many additional questions she must answer correctly in a row.
To find the necessary total number of correct answers (T) for 80% accuracy, we use the equation:
0.80 = (10 + I) / (16 + I)
where I represents the number of consecutive questions Cheryl answered correctly after the initial 16 questions.

what are all the possible rectangles with whole-number side
lengths that have a perimeter of 10 units.
Answer:
So (L,W) possibilities are:
(1,4),(4,1),(2,3),(3,2)
That makes 4 possibilities.
Step-by-step explanation:
The perimeter of a rectangle is P=2L+2W where L is the length and W is the width.
We have that P=10, so 10=2L+2W.
10=2L+2W
10=2(L+W) By factoring using the distributive property.
2(5)=2(L+W) I factored 10 as 2(5).
If 2(5)=2(L+W), then 5=L+W.
Whole numbers are {0,1,2,3,4,5,6,7,8,9,10,...}. They are your counting numbers and 0.
I think they want natural numbers {1,2,3,4,...}. This is also just called the counting numbers. The reason I think they want this because if one of the dimensions is 0, we won't actually have a rectangle.
So now looking for numbers from this set that satisfy: L+W=5.
L+W=5
1+4=5
4+1=5
2+3=5
3+2=5
So (L,W) possibilities are:
(1,4),(4,1),(2,3),(3,2)
That makes 4 possibilities.

Final answer:
To solve the equations using substitution, isolate y from the first equation, substitute it into the second, solve for x, and then use the value of x to find y. The solution to the system is x = -1 and y = -5.
Explanation:
To solve the system of equations by substitution, we will first isolate y in one of the equations and then substitute it into the other equation.
Step 1: Isolate y in the first equation.
We have y = 3x - 2. This equation is already solved for y, so we can use it as our substitution.
Step 2: Substitute y into the second equation.
Our second equation is x - y = 4. We substitute y with 3x - 2 to get x - (3x - 2) = 4.
Step 3: Solve for x.
Now, we simplify and solve for x:
x - 3x + 2 = 4
-2x + 2 = 4
-2x = 4 - 2
-2x = 2
x = -1
Step 4: Substitute x back into the first equation to solve for y.
Using x = -1 in the first equation y = 3x - 2, we get:
y = 3(-1) - 2
y = -3 - 2
y = -5
Therefore, the solution to the system of equations is x = -1 and y = -5.
The problem refers to triangle ABC. Find the area of the triangle. Round to three significant digits. B = 9° 20', C = 80° 40', b = 2.92 ft
Answer:
Area of the triangle is 25.9 feet²
Step-by-step explanation:
* Lets explain how to solve the problem
- In Δ ABC
∵ m∠ B = 9° 20' = 9 + 20/60 = (28/3)°
∵ b = 2.92 feet
- b is the side opposite to angle B
∵ m∠ C = 80° 40' = 80 + 40/60 = (242/3)°
- Lets find c the side opposite to angle C by sing the sine rule
∵ [tex]\frac{b}{sinB}=\frac{c}{sinC}[/tex]
∴ [tex]\frac{2.92}{sin(28/3)}=\frac{c}{sin(242/3)}[/tex]
- By using cross multiplication
∴ [tex]c=\frac{2.92(sin(242/3)}{sin(28/3)}=17.77[/tex]
- The area of the triangle = 1/2 (b)(c)sin∠A
∵ The sum of the interior angles of a triangle is 180°
∴ m∠ A + m∠ B + m∠ C = 180°
∵ m∠ B = (28/3)°
∵ m∠ C = (242/3)°
∴ m∠ A + 28/3 + 242/3 = 180
∴ m∠ A + 90° = 180° ⇒ subtract 90 from both sides
∴ m∠ A = 90°
∴ Area of the triangle = 1/2 (2.92)(17.77) sin(90)
∵ sin(90) = 1
∴ Area of the triangle = 1/2 (2.92)(17.77) = 25.9 feet²
* Area of the triangle is 25.9 feet²

Find the product.
(y-3)(y-4)=
Answer:
y^2+12-7y
Step-by-step explanation:
(y-3)(y-4)
I will split it up for us
y*y= y^2
-3*y= -3y. \
y*-4= -4y. / -7y
-3*-4= 12
y^2+12-7y
The product of (y-3)(y-4), is y^2 - 7y + 12.
To find the product of (y-3)(y-4), we will use the FOIL method, which stands for First, Outer, Inner, Last. This method is used to multiply two binomials.
First: Multiply the first terms of each binomial: y × y = y^2.
Outer: Multiply the outer terms: y × -4 = -4y.
Inner: Multiply the inner terms: -3 × y = -3y.
Last: Multiply the last terms of each binomial: -3 × -4 = 12.
Adding these products together, we get: y^2 - 4y - 3y + 12. Simplifying by combining like terms, the final product is: y^2 - 7y + 12.

Sound travels along a telephone cable at 1.91 * 10^8 ms^-1 .How long does it take Tetsuo's voice to travel from his office phone in Tokyo to his wife's phone 3740m away?
Answer:
1.958 * 10^-5 seconds or 0.00001958 seconds.
Step-by-step explanation:
3740 = 3.74 * 10^3 in scientific notation.
Time = distance / speed.
= 3. 74 * 10^3 / 1.91 * 10^8
= 1.958 * 10^-5 seconds.
It takes Tetsuo's voice approximately 1.96*10^-5 seconds to travel from his office phone in Tokyo to his wife's phone 3740m away using the speed of sound in telephone cables.
Explanation:SolutionTo find the time it takes for sound to travel a certain distance, we can use the formula time = distance / speed. In this case, the speed of sound along the telephone cable is 1.91 * 10^8 ms⁻¹ and the distance is 3740m.
So the time = 3740 / 1.91 * 10^8 = 1.96 * 10^-5 seconds.
Therefore, it takes Tetsuo's voice approximately 1.96*10^-5 seconds to travel from his office phone in Tokyo to his wife's phone 3740m away.

The circumference of a circle is 20 π.what is the radius of this circle
Answer:
The correct option is 10....
Step-by-step explanation:
The formula of circumference of the circle is:
C = 2πr
where C is the circumference of the circle
r = radius
In this question we have given the circumference and we have to find out the radius:
Thus substitute the values in the formula:
C = 2πr
20π= 2πr
Move 2π to the L.H.S.
20π/2π = r
Cancel out π by π and 20/2 by the table of 2
Therefore we have:
10=r
Thus the correct option is 10....

What is the y-intercept of the line perpendicular to the line y = -x + 1 that includes the point (4, 1)?
Answer:
-3
Step-by-step explanation:
If a line is perpendicular to another the product of their slope should equal -1. The slope of the first equation is -1 and -1*1=-1 so the slope of the second equation is 1. That means that the equation looks like y=x+b. We know that when x is 4 y is 1. So plugging in those values you get 1=4+b, subtracting 4 you get -3=b. So the y-intercept is -3
