The time at which the velocity falls to zero can be expressed as the cube root of 5/9.
What is velocity ?
Velocity is the directional speed of an object in motion as an indication of its rate of change in position as observed from a particular frame of reference and as measured by a particular standard of time.
The velocity of an object can be found by taking the derivative of the position with respect to time.
So, the velocity can be expressed as:
v(t) = d(x(t))/dt = (-0.20)3t^2 (3.0)2t (10.0) + 6.0
The velocity of an object is zero when v(t) = 0, so we can set v(t) = 0 and solve for t:
(-0.20)3t^2 (3.0)2t (10.0) + 6.0 = 0
(-0.20)3t^2 (3.0)2t = -6.0 / (10.0)
(-0.20)3t^2 (3.0)2t = -0.6
t^2 (3.0)2t = -0.6 / (-0.20)3 = 5.0
t^3 = 5.0 / (3.0)2 = 5.0 / 9.0
t = (5.0 / 9.0)^(1/3)
So, the time at which the velocity falls to zero can be expressed as the cube root of 5/9.

There i only one carton of pear. Jo want to buy 3/4 of it, and Max to buy 1/3 of it. Will there be enough?
The only one carton of pear is not enough because the sum of both Jo and Max requirement is max than the one.
There is only one carton of pear.
Jo want to buy 3/4 of it, and Max to buy 1/3 of it.
To check whether one carton of pear is enough for both Jo and Max we firstly add the part of Jo and Max to find the total pear they want. Then we check the one pear is enough y subtracting.
Now finding the total pear that Jo and Max want:
Total Pear they want = Jo want + Max want
Total Pear they want = 3/4 + 1/3
To add we equal the denominator.
Multiply and divide by 12 on both number
Total Pear they want = 3/4 × 12/12 + 1/3 × 12/12
Total Pear they want = 9/12 + 4/12
Total Pear they want = (9 + 4)/12
Total Pear they want = 13/12
Total Pear they want = 1 1/12
As we can see that the sum of both Jo and Max requirement is max than the one pear. So the only one carton of pear is not enough.

Assume that all schedules are equally likely. Determine the probability for each of the following: (a) All hip surgeries are completed before another type of surgery (b) The schedule begins with a hip surgery (c) The first and last surgeries are hip surgeries. (d) The first two surgeries are hip surgeries.
To calculate the probability a) P = (4C4 x 3C3)/(12C12) = 1/12. (b) P = (4C1 x 3C3 x 5C5)/(12C12) = 1/12. (c) P= (4C1 x 3C3 x 4C3 x 5C4)/(12C12) = 1/9. (d) P= (4C2 x 3C3 x 5C5)/(12C12) = 1/36.
(a) To calculate the probability that all hip surgeries are completed before another type of surgery, we first determine the total number of possible combinations of surgeries (12C12). We then calculate the number of combinations with four hip surgeries and three knee surgeries (4C4 x 3C3). We divide the number of combinations with the desired schedule by the total number of combinations to get the probability (1/12). (b) To calculate the probability that the schedule begins with a hip surgery, we first determine the total number of possible combinations of surgeries (12C12). We then calculate the number of combinations with one hip surgery, three knee surgeries, and five shoulder surgeries (4C1 x 3C3 x 5C5). We divide the number of combinations with the desired schedule by the total number of combinations to get the probability (1/12). (c) To calculate the probability that the first and last surgeries are hip surgeries, we first determine the total number of possible combinations of surgeries (12C12). We then calculate the number of combinations with one hip surgery at the start, three knee surgeries, three hip surgeries, and four shoulder surgeries (4C1 x 3C3 x 4C3 x 5C4). We divide the number of combinations with the desired schedule by the total number of combinations to get the probability (1/9). (d) To calculate the probability that the first two surgeries are hip surgeries, we first determine the total number of possible combinations of surgeries (12C12). We then calculate the number of combinations with two hip surgeries, three knee surgeries, and five shoulder surgeries (4C2 x 3C3 x 5C5). We divide the number of combinations with the desired schedule by the total number of combinations to get the probability (1/36).

In a repeated measures design with 20 subjects, each subjected to 2 measurements (before and after stimulus presentation), the degrees of freedom in the test would be 19.
DF in Repeated Measures ExperimentThe problem is about an experiment in which a measurement is taken before and after a stimulus is presented to 20 subjects. The aim is to determine the number of degrees of freedom in the data analysis of the experiment.
Degrees of freedom (df) are a measure of the amount of variability in a set of data that is free to vary in the calculation of a statistical test. In a repeated measures design, the degrees of freedom are calculated as the number of subjects minus 1. In this case, with 20 subjects, the degrees of freedom would be 19.
The concept of degrees of freedom is used in both mathematics and physics, but the specific context of a t-test for dependent samples is commonly used in statistical analysis, particularly in the social sciences, psychology, and education research. So, it is more related to mathematics.

Answer:If at the end of any year a car is worth 5% less than what it was worth at the beginning of the year, we can say that the car's value decreases by a factor of 0.95 (1 - 0.05) every year.
To find the car's value in December 2009, we can use the formula:
Car value at end of year = Car value at beginning of year * (1 - 0.05)^(number of years)
Plugging in the given values, we get:
Car value in December 2009 = 10,000 * (1 - 0.05)^1 = 9,500

How likely something is to occur is known as its probability. We can discuss the probabilities of various outcomes—how likely they are—when we aren't sure how a particular event will turn out. Statistics describes the examination of events subject to probability.
To find:
P(X < 5.5)
Z = -1.0
However;
P(X< 5.5) = P(Z < -1.0)
P(X< 5.5) = 0.1587

alice is holding up the top vertex of a triangular banner attached to the ground by two anchors on the bottom vertices. what is the area of the banner of alice reaches her arm up above the ground and the anchors on the bottom are apart?
Let's call the length of the bottom side of the triangular banner "b". When Alice reaches her arm up above the ground, the height of the banner changes from its original height of "h" to a new height of "h'". The area of the banner can be calculated using the formula:
A = (b * h') / 2
The new height "h'", can be calculated using the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the two shorter sides is equal to the square of the longest side (the hypotenuse).
In this case, the two shorter sides are the original height "h" and the difference between the length of Alice's arm and the original height, which we will call "d". The longest side is the distance between the two anchors, which we will call "a".
So:
h^2 + d^2 = a^2
We can solve for "d" using this equation:
d = sqrt(a^2 - h^2)
And then we can find "h'" using:
h' = h + d
So the area of the banner can be calculated as:
A = (b * (h + sqrt(a^2 - h^2))) / 2
The solution assumes that the banner is a right triangle, with one vertex at the top, one vertex at the bottom, and a straight side along the ground connecting the two bottom vertices.

Step-by-step explanation:
DeAndre has 190 square inches of plastic to make a cylindrical bird feeder. Which design should he choose? Explain.
DeAndre should select the shape that satisfy the equation -
r(2h + r) = (190/π).
What is cylinder?A cylinder has traditionally been a three-dimensional solid, one of the most basic of curvilinear geometric shapes. In elementary geometry, it is considered a prism with a circle as its base. A cylinder may also be defined as an infinite curvilinear surface in various modern branches of geometry and topology.Given is that DeAndre has 190 square inches of plastic to make a cylindrical bird feeder.
He should choose the design whose total surface area is equivalent to 190 square inches. We can write the total surface area as -
2πrh + πr² = 190
πr(2h + r) = 190
r(2h + r) = (190/π)
Therefore, DeAndre should select the shape that satisfy the equation -
r(2h + r) = (190/π).
