A high-performance composite flywheel rotor can spin anywhere between 30,000 and 100,000 revolutions per minute. What
is the range of degrees through which the composite flywheel can travel in a minute? Write your answer in scientific
notation.
Answers
Answer:
Step-by-step explanation:
1 revolution will equal 360 degrees
Because of that 30,000 revolution would be 10,800,000 degrees
100,000 rev would equal 36,000,000 degrees
The range through which the composite flywheel rotates in one minute be denoted by ' F ' . (1.08 x 107)° F (3.6 x 107)°
The range of degrees the composite flywheel can travel in a minute is 2.52 × 10⁷ degrees/minute.
What is the Scientific Notation?Scientific Notation is a way of writing down in the easy form of very large or very small numbers.
The range of revolutions per minute for the rotor is from 30,000 to 100,000, which means that the rotor can spin a total of 70,000 revolutions per minute (100,000 - 30,000 = 70,000).
To find the range of degrees through which the composite flywheel can travel in a minute, we need to multiply the range of revolutions by the number of degrees in one revolution.
A full revolution is 360 degrees, so the composite flywheel can travel in a minute :
70,000 revolutions/minute × 360 degrees/revolution = 25,200,000 degrees/minute
This can be written as 2.52 × 10⁷ in scientific notation.

What is the equivalent to the product below when x>_0?
√5x² •√15x²
Answers
√(5x²) • √(15x²) = √(5x² * 15x²)
Using the property of square roots that √(a * b) = √a * √b, we can simplify further:
√(5x² * 15x²) = √(5 * 15 * x² * x²)
Next, we simplify the numerical part:
√(5 * 15 * x² * x²) = √(75 * x² * x²)
Since x ≥ 0, x² is always non-negative, so we can remove the square root:
√(75 * x² * x²) = x * x * √75
Finally, we simplify the square root of 75:
x * x * √75 = x² * √75
Therefore, the equivalent expression is x² * √75 when x ≥ 0.

If George is 33 1/3% richer than Pete, than Pete is what percent poorer than George?
Answers
Answer:
25%
Step-by-step explanation:
George is 33\(\frac{1}{3}\)% (\(\frac{100}{3}\)%) richer than Pete. Let Pete's percentage of wealth be 100%.
Thus George percentage of wealth = 100% + \(\frac{100}{3}\)%
= \(\frac{400}{3}\)%
= 133\(\frac{1}{3}\)%
Pete's percent poorer than George can be determined by;
= \((\frac{100}{3})\) ÷ \((\frac{400}{3} )\) × 100
= \((\frac{100}{3})\) × \(\frac{3}{400}\) ×100
= 0.25 × 100
= 25%
Pete is 25% poorer than George.

What are the domain and range of the function f(x)=-x+3-2? domain: -3 -2 domain: -3 -3 range: y<-2 domain: x>-3 range:y>-2
Answers
For given function function f(x)=-x+3-2, the domain is x > -3 and the range is y ≤ 2. So, correct option is D.
The function f(x)=-x+3-2 is a linear function in the form y=mx+b, where m is the slope and b is the y-intercept. In this case, the slope is -1 and the y-intercept is 1. Therefore, the graph of the function is a straight line that intersects the y-axis at (0,1) and has a slope of -1, meaning that it decreases by 1 for every 1 unit increase in x.
The domain of the function is the set of all possible values of x for which the function is defined. Since there are no restrictions on the value of x in the equation f(x)=-x+3-2, the domain is all real numbers, or (-∞, ∞).
The range of the function is the set of all possible values of y that the function can output. In this case, the lowest possible value of y occurs when x approaches positive infinity, and the highest possible value of y occurs when x approaches negative infinity. Therefore, the range is all real numbers less than or equal to 2, or y ≤ 2.
So, the domain is x ∈ (-∞, ∞) and the range is y ≤ 2. Alternatively, the domain can also be expressed as x > -3, since that is the minimum value of x at which the function is defined.
Correct option is D.

The equation of the line in slope-point form, slope-intercept form, and standard form are y = -100x + 1250, y - 1250 = -100(x-0) and 100x + y = 1250 respectively
How to write the equation of a line in point-slope form?
The equation of a line in point-slope form is given as y − y 1 = m ( x − x 1),
where ( x 1, y1 ) is the point given and m is the slope
m = y2-y1 / x2-x1, where x1 = 0, y1 = 1,250 and x2 = 5, y2 = 750
m = 750-1250 / 5-0
m = -500/5 = -100
Thus, the slope-point form:
y − y 1 = m ( x − x 1 )
y - 1250 = -100(x-0)
The equation of a line in slope-intercept form is given as y = mx+c,
where (x, y) is the point given, m is the slope and c is the y-intercept
where x1 = 0, y1 = 1,250 and m = -100
y = mx + c
1250 = -100(0) + c
c = 1250
Thus, the equation in slope-intercept form is:
y = -100x + 1250
The equation of a line in standard form is given as ax + by = c, where a, b, c are real numbers
Rewrite y = -100x + 1250. Thus, the equation in standard form is:
100x + y = 1250

How to determine the differenceThe Z-test becomes possible in the comparison of the mean of a sample to that of the population. It evaluates if there is statistical relevance in the difference between the mean of a sample and the mean of the whole population
In contrast, ANOVA is employed to contrast the averages of three or more separate groups. This assesses if there is a noteworthy distinction in the averages of said groups. The F-statistic in ANOVA is computed by assessing the disparity in variability between groups and the variability within groups.

we know that the diameter of a circle d = 2 r
The circumference of the circle = 2π r
Given that the circumference of the circle = 80 feet
Step(ii):-
The circumference of the circle = 2π r = 80
⇒ π (2r )= 80
⇒ πd = 80
⇒ \(d = \frac{80}{3.14}\)
