a particle moves in a circle 1.50 m in radius. through what angle in radians does it rotate if it moves through an arc length of 2.50 m? what is this angle in degrees?
The angle through which the particle rotates in radians is 1.67 radians, while the angle in degrees is 605° (rounded to the nearest degree).
A particle moves in a circle of radius 1.50 m. If it moves through an arc length of 2.50 m, we are to determine the angle through which it rotates in radians and in degrees.
Let the angle through which it rotates be denoted as θ, and the radius of the circle be denoted as r, thus, we can write:
L = rθ
where L is the length of the arc. We are to determine θ if r = 1.50 m and L = 2.50 m.
Substituting L = 2.50 m and r = 1.50 m into L = rθ, we have: 2.50 m = 1.50 mθ
Dividing both sides by 1.50 m, we obtain:
θ = 2.50 m / 1.50 m = 1.67 radians
The angle through which the particle rotates in radians is 1.67 radians, while the angle in degrees is 605° (rounded to the nearest degree).

What is the angle in both radians and degrees determined by an arc of length 4π meters on a circle of radius 16 meters? NOTE: Enter the exact answers. Do not include symbols in the answer boxes. The angle, in radians, is The angle, in degrees, is
The formula to determine the angle subtended by an arc is:θ = (L/r), where θ is the angle in radians, L is the length of the arc, and r is the radius of the circle.
We are given a circle with a radius of 16 meters and an arc length of 4π meters. Therefore, we can plug in the values of L and r to obtain the angle in radians:
θ = (L/r) = (4π/16) = π/4 radians
We can convert radians to degrees using the formula:
π radians = 180 degrees
Therefore, we can convert the angle in radians to degrees as follows:
θ (in degrees) = (θ in radians) × (180/π) = (π/4) × (180/π) = 45 degrees
Hence, the angle subtended by an arc of length 4π meters on a circle of radius 16 meters is π/4 radians or 45 degrees.Conclusion:Thus, the angle, in radians, is π/4 and the angle, in degrees, is 45 degrees.

How to obtain the area of a rectangle?To obtain the area of a rectangle, you need to multiply its length by its width. The formula for the area of a rectangle is:
Area = Length x Width.
The dimensions for this problem are given as follows:
x + 3 and x + 5.
As the area is of 48 square units, we have that:
(x + 3)(x + 5) = 48
x² + 8x + 15 = 48
x² + 8x - 33 = 0.
The coefficients are given as follows:
a = 1, b = 8, c = -33.
Using a quadratic function calculator, the positive root is given as follows:
x = 3.
Hence the dimensions are:
x + 3 = 6.x + 5 = 8.More can be learned about the area of a rectangle at brainly.com/question/25292087

So how do you do ratios and rates and portions im failing in math and i dont know what to do can you help?
Answer:
The most common way to write a ratio is as a fraction, 3/6. We could also write it using the word "to," as "3 to 6." Finally, we could write this ratio using a colon between the two numbers, 3:6. Be sure you understand that these are all ways to write the same number.
A rate is a special ratio in which the two terms are in different units. For example, if a 12-ounce can of corn costs 69¢, the rate is 69¢ for 12 ounces. The first term of the ratio is measured in cents; the second term in ounces. You can write this rate as 69¢/12 ounces or 69¢:12 ounces.
Astronauts increased in height by an average of approximately 40mm (about an inch and a half) during the Apollo Soyuz missions, due to the absence of gravity compressing their spines during their time in space. Does something similar happen here on Earth? An experiment supported by NASA measured the heights of six men immediately before going to bed, and then again after three days of bed rest. On average, they increased in height by 14mm, with standard deviation 0.66mm. Find the 95% confidence interval for the change in height after three days of bed rest.
The confidence interval for the change in height after three days of bed rest is approximately (13.308, 14.692) mm.
So we can be 95% confident that the true change in height after three days of bed rest falls within this interval.
How to find the cofidence interval?
To find the 95% confidence interval for the change in height after three days of bed rest, we can use the formula for a confidence interval for the mean difference in paired data:
CI = x ± t * (s / √n)
Where the variables are:
x is the sample mean difference (average change in height),t is the critical value from the t-distribution for the desired confidence level (95% confidence corresponds to a t-value with 5 degrees of freedom, which is approximately 2.571),s is the sample standard deviation of the differences (given as 0.66mm),n is the sample size (given as 6).Let's calculate the confidence interval:
x = 14mm (average change in height)t = 2.571 (critical value for 95% confidence level with 5 degrees of freedom)s = 0.66mm (sample standard deviation of the differences)n = 6 (sample size)CI = 14 ± 2.571 * (0.66 / √6)
Calculating the value inside the parentheses:
0.66 / √6 ≈ 0.2691
Calculating the confidence interval:
CI = 14 ± 2.571 * 0.2691
CI = 14 ± 0.692
That is the confidence interval.

0.3x-2.1x=-4.4-5.14
-1.8x=-9.54
x=-9.54/-1.8
To remove the decimal point, multiply with 100 on both numerator and denominator as their are two digits after the decimal point
x=-9.54 × 100/-1.8 × 100
therefore you will get,
x=-954/-180
cut the negative sign from both numerator and denominator
x=954/180

what are the zeros of the function graph the function. y=x(x 2)(x 5)
the zeros of the function are x = 0, x = -5.
The given function is y = x(x²)(x + 5).
To find the zeros of this function, we need to set y equal to zero and solve for x.
So, y = 0x(x²)(x + 5) ⇒ 0 = x(x²)(x + 5)
We can see that the left side is zero. So, either x or (x²)(x + 5) is zero.
Thus, the zeros of the function are: x = 0, x² = 0
⇒ x = 0, x + 5 = 0
⇒ x = -5
Therefore, the zeros of the function are x = 0, x = -5.

The volume of the Venus is approximately 9.4 x 10^11 km^3. The volume mars is approximately 1.6 x 10^11.
Part A: about how many times as great as the volume of mars is the volume of Venus? Round to the nearest tenth.
Part B: the volume of earth is approximately 0.69 x 10^-1 times larger than the volume of mars. What is the approximate volume of earth?
Answer:
Step-by-step explanation:
Given
volume of the Venus = 9.4 x 10^11 km^3
The volume mars is approximately = 1.6 x 10^11km³
A) In order to know how many times as great as the volume of mars is the volume of Venus, we take the ratio of volume of Venus to volume of mars.
Ratio = volume of Venus/volume of mars
Ratio = 9.4 x 10^11 km³/1.6 x 10^11km³
Ratio = 9.4/1.6
Ratio = 5.875
Ratio = 5.9(to the nearest tenth)
Hence the volume of venus is approximately 5.9 great as volume of mars.
B) If volume of earth is approximately 0.69 x 10^-1 times larger than the volume of mars, then the amount by which earth is greater than mars is expressed as:
0.69 x 10^-1 × volume of mars
= 0.69 x 10^-1 × 1.6 x 10^11.
= 1.104×10^{-1+11}
= 1.104×10^10
Volume of earth will be 1.104×10^10+1.6 x 10^11.
Volume of earth = 0.1104×10^11+1.6 x 10^11.
Volume of earth = 1.7104×10¹¹ km³
Hence the approximate volume of earth is 1.7104×10¹¹km³
The volume of Mars is 5.875 times greater than the Volume of earth.
Volume is a quantity expressing the amount of three-dimensional space enclosed by a closed surface. It shows how much space there is within a three-dimensional object.
Part A:
Comparison of Venus to Mars = 9.4 x 10^11 km³ / 1.6 x 10^11 km³ = 5.875Part B:
Volume of earth = 1.6 x 10^11 + (1.6 x 10^11 * 0.69 x 10^-1) = 1.7104 * 10¹¹ km³The volume of Mars is 5.875 times greater than the Volume of earth.
