The rate of change of volume with respect to R is 4πR².

The rate of change function is defined as the rate at which one quantity is changing with respect to another quantity. In simple terms, in the rate of change, the amount of change in one item is divided by the corresponding amount of change in another. The rate of change formula gives the relationship describing how one quantity changes in relation to the change in another quantity. The rate of change from the coordinates of y to the coordinates of x can be found out as Δy/ Δx = (y2 - y1 )/ (x2 - x1 ). For a linear function, the rate of change m is represented in the slope-intercept form for a line: y=mx+b whereas the rate of change of functions is otherwise defined as, (f(b)-f(a))/ b-a.

The volume of the sphere is:

V = (4π/3)(R³)

Differentiating volume with respect to radius gives:

dV/dR  = (4π/3)× (3R²) = 4πR²

Thus, the rate of change of volume with respect to R is 4πR².

One is not considered a prime factor.

One has only a single element, which is itself, hence it is not regarded as a prime number. A prime number is a positive integer greater than 1 with just itself and the number one as its other positive divisors. Since there is only one divisor of one, one is not regarded as a prime number. Additionally, 1 does not adhere to the conventional characteristics of prime numbers and is regarded as a unit in mathematics.

For instance, a number's value is unaffected by division or multiplication by one, and it is always one when raised to any power. Since one does not meet the criteria for primes and does not share their characteristics, it is likewise excluded from the set of prime numbers.

Since Paul's English class is located in the same quadrant as the library, the coordinates of the English classroom include the following: B: (−4, 5).

In Mathematics, the translation of a geometric figure or graph to the right simply means adding a digit to the value on the x-coordinate (x-axis) of the pre-image or function.

On the other hand (conversely), the translation a geometric figure or graph downward simply means subtracting a digit from the value on the y-coordinate (y-axis) of the pre-image or function.

Since the library is located in the fourth quadrant in which the value on the x-coordinate (x-axis) is positive while the value on the y-coordinate (y-axis) is negative, we can reasonably infer and logically deduce that its coordinates would be translated to the right and then downward.

In conclusion, the coordinates of the English classroom would most likely have negative x-coordinate (x-axis) and a positive y-coordinate (y-axis);

Coordinates of the English classroom = (-4, 5).

The angle formed by the intersection of secant and tangent is as follows:

m∠P = 51.83 degrees.

A line that touches the circle at a single point is known as a tangent to a circle. Secant is straight line that intersects a curve at two or more points.

Therefore, the measure of the angle formed by the intersection of a tangent and a secant is equals to half the difference of the intercepted arcs.

Hence,

m∠P = 1 / 2 (125.83 - 22.17)

m∠P = 1 / 2 (103.66)

m∠P = 1 / 2 × 103.66

m∠P = 51.83 degrees

Therefore, the angle formed by the intersected secant and tangent is 51.83 degrees.

This is a classic example of an open question, since there are answers as many as possible assumptions. In this case, answer change if swimmer's speed is changed. We shall consider two cases: (i) Average swimmer (v = 2 miles per hour), (ii) Olympic swimmer (v = 6 miles per hour).

Under the assumption of uniform motion, distance (s), in miles, is the product of speed (v), in miles per hour, and time (t), in hours (please notice that an hour is equal to 60 minutes):

s = v · t

Average swimmer (v = 2 mi / h, t = 1 / 60 h)

s = 2 · (1 / 60)

s = 2 / 60

s = 1 / 30 mi

The amount of each solution that should be mixed together to obtain the desired target solution is;

160 quarts of the solution that contains 3 parts salt to 5 parts water

120 quarts of the solution that contains 2 parts salt to 8 parts water

The parameters are;

Solution A contains 2 parts salt to 8 parts water

Solution B contains 3 parts salt to 5 parts water

Target Mixture contains 3 parts salt to 7 parts water:

Expressing the salt concentration in decimal form;

Solution A: 2/(2 + 8) = 2/10

= 0.20 salt

Solution B: 3/(3 + 5) = 3/8

= 0.375 salt

Mixed Solution: s/(3 + 7) = 3/10

= 0.30 salt

Since target mixture is 280 quarts;

If the amount of 0.375 salt present in mixed solution is denoted by x

Then, the amount of 0.20 salt is expressed as;

y = 280 – x

Using a general mixture equation, we will have;

0.375x + 0.20(280 - x) = 0.30(280)

0.375x + 56 - 0.20x = 84

Subtract 56 from both sides of the equation

0.375x - 0.20x + 56 – 56 = 84 – 56

0.375x - 0.20x = 28

0.175x = 28

Divide both sides of the equation by 0.175

0.175x/0.175 = 28/0.175

x = 160

Thus;

y = 280 – x

y = 280 – 160

y = 120

Therefore,

x = 160 quarts of the solution that contains 3 parts salt to 5 parts water

y = 120 quarts of the solution that contains 2 parts salt to 8 parts water

Step-by-step explanation:

Translation 2 left and 2 up

To translate (move) a point two units to the left, we subtract 2 from its x-value.  Similarly, to translate (move) a point two units up, we add 2 to its y-value.

Rotation 90° counterclockwise

When rotating a point 90° counterclockwise, the y-value becomes negative, and the x and y switch:

Translation 2 right and 2 down

To translate (move) a point two units to the right, we add 2 to its x-value.  Similarly, to translate (move) a point two units down, we subtract 2 from its y-value.
