The radius r of a sphere is increasing at the uniform rate of 0.3 inches per second. At the instant when the surface area S becomes 100pi square inches, what is the rate of increase, in cubic inches per second, in the volume V?
The rate of increase in the volume V is 30π cubic inches per second when the surface area S becomes 100π square inches.
What is volume?
Volume refers to the amount of three-dimensional space occupied by an object or a substance.
To find the rate of increase in the volume V of a sphere when the surface area S becomes 100π square inches, we need to use the formulas relating the surface area and volume of a sphere to its radius.
The surface area S of a sphere is given by the formula:
\(S = 4\pi r^2,\)
where r is the radius of the sphere.
The volume V of a sphere is given by the formula:
\(V = (4/3)\pi r^3.\)
To find the rate of increase in volume with respect to time, we need to differentiate the volume formula with respect to time.
Given that the radius r is increasing at a uniform rate of 0.3 inches per second, we can write:
dr/dt = 0.3 inches per second.
Now, let's differentiate the volume formula with respect to time:
\(dV/dt = d/dt [(4/3)\pi r^3].\)
Using the power rule of differentiation, we get:
\(dV/dt = (4/3)\pi * 3r^2 * (dr/dt).\)
Simplifying further, we have:
\(dV/dt = 4\pi r^2 * (dr/dt).\)
Since we want to find the rate of increase in cubic inches per second, we need to express the volume in cubic inches.
Substituting the value of the surface area S = 100π square inches into the surface area formula:
\(100\pi = 4\pi r^2.\)
Dividing both sides by 4π, we get:
\(r^2 = 25.\)
Taking the square root of both sides, we find:
r = 5.
Now, we can substitute the value of r into the rate of increase formula:
\(dV/dt = 4\pi(5^2) * (0.3).\)
Simplifying the expression:
dV/dt = 4π(25) * 0.3.
dV/dt = 30π cubic inches per second.
Therefore, the rate of increase in the volume V is 30π cubic inches per second when the surface area S becomes 100π square inches.

Graph the equation . h=-16t²+80
A graph that represent the quadratic equation h = -16t² + 80 is shown in the image attached below.
What is the graph of a quadratic function?In Mathematics and Geometry, the graph of a quadratic function would always form a parabolic curve because it is a u-shaped. Based on the given quadratic function, we can logically deduce that the graph would be a downward parabola because the coefficient of x² is negative and the value of "a" is less than zero (0).
Since the leading coefficient (value of a) in the given quadratic function h = -16t² + 80 is negative 16, we can logically deduce that the parabola would open downward and the x-intercept (roots) is given by the ordered pair (-2.236, 0) and (2.236, 0).
In conclusion, the vertex is given by the ordered pair (0, 80).

Find C =AB, if A = [2 9] B = [3 6 1]
[ 10 6]
The exercise involves finding the product C = AB, where matrix A is given by [2 9] and matrix B is given by [3 6 1]. We need to perform the matrix multiplication to obtain the resulting matrix C.
Let's calculate the matrix product C = AB step by step:
Matrix A has dimensions 2x1, and matrix B has dimensions 1x3. To perform the multiplication, the number of columns in A must match the number of rows in B.
In this case, both matrices satisfy this condition, so the product C = AB is defined.
Calculating AB:
AB = [23 + 912 26 + 94 21 + 95]
[103 + 612 106 + 64 101 + 65]
Simplifying the calculations:
AB = [6 + 108 12 + 36 2 + 45]
[30 + 72 60 + 24 10 + 30]
AB = [114 48 47]
[102 84 40]
Therefore, the product C = AB is:
C = [114 48 47]
[102 84 40]
In summary, the matrix product C = AB, where A = [2 9] and B = [3 6 1], is given by:

An instructor is preparing a report showing mid-semester grades and notes that the mean, median, and mode are all exactly 76.00. What can she conclude
The instructor can conclude that the class performed around the average and that the distribution of grades is likely to be symmetrical. This can also imply that there is no skewness or bias in the data. Answer more than 100 words:When an instructor notes that the mean, median, and mode are all exactly 76.00, it can be inferred that the distribution of grades in the class is roughly symmetrical. This indicates that there are nearly equal numbers of students above and below the average grade.
The mean, median, and mode are three measures of central tendency that are used to summarize the distribution of a dataset. The mean is calculated by adding all the values in the dataset and dividing by the number of observations, while the median is the middle value when the dataset is ordered from smallest to largest. The mode is the value that occurs most frequently in the dataset. When all three measures of central tendency are equal, as in this case, it means that the dataset is roughly symmetrical and there is no skewness or bias. This can also indicate that the dataset is normally distributed, which means that it follows a bell-shaped curve.The instructor can conclude that the class performed around the average, as the mean, median, and mode are all 76.00.
However, it is important to note that this does not give any information about the spread of the dataset. In other words, the instructor cannot tell from this information alone whether the grades were tightly clustered around the average or widely dispersed. For this reason, it may be useful to calculate additional measures of spread, such as the range or standard deviation, to get a better understanding of the distribution.
The instructor can conclude that the class performed around the average and that the distribution of grades is likely to be symmetrical, with no skewness or bias. However, it is important to remember that this information alone does not provide any insight into the spread of the dataset. Additional measures of spread would need to be calculated to determine the degree of variability in the grades.

xo= 0 because they didn't give it so we suppose it as 0
x= vt
x= 6m/s * 15s
x= 90m
Answer:
5400 meters
Step-by-step explanation:
In order to find the answer to this question you need to multiply the amount traveled per second by the amount of seconds he ran, then just convert that answer into meters.
1 second = 6 m/s
15 seconds = 90 m/s

Raquel throws darts at a coordinate grid centered at the origin. Her goal is to create a line of darts. Her darts actually hit the coordinate grid at (–5, 0), (1, –3), (4, 5), (–8, –6), (0, 2), and (9, 6). Which equation best approximates the line of best fit of the darts?
y = 0.6x + 0.6
y = 0.1x + 0.8
y = 0.8x + 0.1
y = 0.5x + 0.6
The line of best fit of the darts is y = 0.6x + 0.6 after calculating using the formula option first is correct.
What is the line of best fit?A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
We can calculate the line of best fit by using the slope(m) and intercept(c)
\(\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2} \\\\\rm c = \dfrac{\sum y -m \sum x}{n}\)
Let's suppose the line of the best fit is:
y = mx + c
m = 0.6
c = 0.6
y = 0.6x + 0.6
Thus, the line of best fit of the darts is y = 0.6x + 0.6 after calculating using the formula option first is correct.

The equation or system of equations that can be used to determine the number of cats and dogs Bea has in her pet shop is d = 2c - 5 d + 3 = c + 3. We can solve the system of equations using substitution and plug it back into either equation to find the value of d, which is 8 cats and 10 dogs.
How will we determine the number of cats and doge Beas initially had in her pet shop?The equation or system of equations that can be used to find the number of cats and dogs Bea has in her pet shop is:
d = 2c - 5
d + 3 = c + 3
No, Bea's Pet Shop could not initially have 15 cats and 20 dogs. This is because the equation or system of equations states that the number of dogs is five less than twice the number of cats, which would mean that 15 cats would result in 25 dogs, which is not equal to 20.
To determine algebraically the number of cats and the number of dogs Bea initially had in her pet shop, we can use the equation or system of equations that we previously created.
d = 2c - 5
d + 3 = c + 3
We can solve the system of equations using substitution:
d = 2c - 5
d + 3 = c + 3
d + 3 = c + 3
d = c + 3
2c - 5 = c + 3
2c = c + 8
c = 8
Once we determine the value of c, we can plug it back into either equation to find the value of d:
d = 2(8) - 5
d = 15 - 5
d = 10

in a game a player throws a dart at the object shown here. if the player throws two darts, what is the probability they both land in a shaded region
The probability of an event happening is represented as a fraction, with the numerator being the number of favorable outcomes and the denominator being the total number of outcomes.
In this case, if the player throws two darts, the probability that both land in a shaded region is equal to the product of the probabilities of each dart landing in the shaded region.
If the shaded region is a circle with radius r and the darts are randomly thrown onto a larger circle with radius R, then the probability of a dart landing in the shaded region is given by:
P = (Area of shaded region) / (Area of larger circle) = (πr^2) / (πR^2)
So, the probability that both darts land in the shaded region is given by:
P = (πr^2 / πR^2) * (πr^2 / πR^2) = (πr^2 / πR^2)^2
Note that the specific values of r and R would depend on the particular game and the dimensions of the object.

To verify whether the languages of two regular expressions r and s are equal, we can follow these steps:
Construct the finite automata for r and s.
Convert both the finite automata to their corresponding deterministic finite automata (DFA).
Minimize the DFAs obtained in step 2.
Compare the minimized DFAs to check if they are equivalent.
If the DFAs are equivalent, then the languages of r and s are also equal.
Alternatively, we can directly compare the regular expressions r and s by using the following algorithm:
Convert both r and s to their equivalent minimal deterministic finite automata (DFA).
Construct the product DFA of the two DFAs obtained in step 1.
Check if the accepting states of the product DFA correspond to the same regular expressions in r and s.
If the accepting states correspond to the same regular expressions, then l(r) = l(s). Otherwise, l(r) ≠ l(s).
