If the temperature of a chemical mixture is tan√x degree celsius after x hours then the rate of change of temperature after π /4 hours is 0.141099

We are given that the temperature of the chemical mixture after x hours is given by:

T(x) = tan(√x)

To find the rate of change of temperature after π/4 hours, we need to find the derivative of T(x) with respect to x and evaluate it at x = π/4.

T'(x) = sec²(√x)/2√x

So, the rate of change of temperature after π/4 hours is given by:

T'(π/4) = sec²(√(π/4))/2√(π/4)

= sec²(π/2)/2√(π/4)

= 1/2√(π/4)

We can simplify this expression as:

T'(π/4) = 1/2(π/2)⁰⁵

The graph of the derivative, F', shows that the slope is positive until x = 2 (the right end of the semicircle) and then becomes zero.

Since the graph of F' consists of two line segments and a semicircle, we can determine the values of F using the information provided.

Let's break down the problem into different intervals based on the graph:

Interval (-∞, -5):

Since we don't have specific information about this interval, we cannot determine the exact value of F(-5).

Interval (-5, 0):

In this interval, we have a line segment. Let's assume the equation of the line segment is y = mx + b. We can find the equation of this line segment by using the slope-intercept form of a line and the given point (2, 1).

The slope of the line can be calculated using the difference in y-coordinates divided by the difference in x-coordinates:

m = (1 - F(2)) / (2 - (-5)) = (1 - 1) / 7 = 0/7 = 0

Since the slope is 0, the equation of the line becomes y = b. Plugging in the point (2, 1) into the equation, we get:

1 = b

Therefore, the equation of the line segment for the interval (-5, 0) is y = 1.

Interval (0, ∞):

In this interval, we have a semicircle. The graph of the derivative, F', shows that the slope is positive until x = 2 (the right end of the semicircle) and then becomes zero. This indicates that the original function F is increasing until x = 2 and remains constant afterward.

Since F(2) = 1, we can conclude that F(x) = 1 for x ≥ 2. Therefore, F(-5) cannot be determined based on the given information.

To use the substitution method to solve the system, we need to solve one of the equations for x or y in terms of the other variable, and then substitute that expression into the other equation to get an equation in one variable that we can solve.

Let's solve the first equation for x in terms of y:

x + 4y = -9

x = -4y - 9

Now we substitute this expression for x into the second equation:

2x + 5y = -6

2(-4y - 9) + 5y = -6

Simplifying this expression, we get:

-8y - 18 + 5y = -6

-3y = 12

y = -4

Now we can substitute this value of y into either of the original equations to find x. Let's use the first equation:

x + 4y = -9

x + 4(-4) = -9

x - 16 = -9

x = 7

Therefore, the solution to the system is x = 7, y = -4.

Now let's look at the answer choices and see which one matches the equation we got by substituting x = -4y - 9 into the second equation:

A) 2(4-9)+ 5y-6 = -10 + 5y - 6 = 5y - 16

B) 21-4y-9)+5% -6 = -4y + 6

C) 2x+5(4-9)=-6 = 2x - 25 = -6

D) 2x+5(-4y-9)=-6 = 2x - 20y - 45 = -6

The answer choice that matches our equation is D), 2x + 5(-4y - 9) = -6.

Answer:

52° is approximately 0.907 radians

Step-by-step explanation:

To find the equivalent radian measure for an angle that measures 52°, we need to convert 52° to radians using the formula:

radians = degrees × π/180

Substituting the value of 52° into the formula, we get:

radians = 52 × π/180

radians ≈ 0.907

Therefore, the equivalent radian measure for an angle that measures 52° is approximately 0.907 radians.

a. The concentration of the drug after 8 hours is equal to 24 mg/L.

b. The interval over which the concentration increases is 0 < t < 2. The interval over which the concentration decreases is 2 < t < ∞.

c. The drug is at its maximum concentration when t = 2 hours and the maximum concentration is 64 mg/L.

d. After the drug reaches its maximum concentration, the number of hours that are required for the concentration to decrease to 16 mg/L is 8 hours.

e. After 1 week and 1 month, we can predict that the concentration of the drug kept decreasing after reaching 20 hours.

f. After the drug is taken orally, it took exactly 2 hours to reach a maximum concentration of 64 mg/L.

By critically observing the graph, the time and concentration of the drug after 8 hours is represented by the order pair (8, 24). Therefore, the concentration is equal to 24 mg/L.

Part b.

For any given function, y = f(x), if the output value (range or y-value) is decreasing when the input value is increased, then, the function is generally referred to as a decreasing function.

For any given function, y = f(x), if the output value (range) is increasing when the input value is increased, then, the function is generally referred to as an increasing function.

By critically observing the graph of the given function, we can reasonably infer and logically deduce the following:

Part c.

The vertex (2, 64) of the graph represent the point where the drug is at its maximum concentration, which is time (t) = 2 hours and the maximum concentration is y = 64 mg/L.

Part d.

After the drug reaches its maximum concentration, the number of hours that are required for the concentration to decrease to 16 mg/L can be calculated from the graph as follows;

Number of hours = 10 - 2

Number of hours = 8 hours.

Part e.

After 1 week and 1 month, it can be predicted that the concentration of the drug kept decreasing after reaching 20 hours.

Part f.

After the drug is taken orally, it took exactly 2 hours to reach a maximum concentration of 64 mg/L. Subsequently, the level of the drug in the bloodstream drops after reaching its maximum concentration, reaching approximately 10 mg/L after 12 hours.

Using the concept of exponential decay, the predicted number of people is  233,176,000

To predict the number of gas-powered cars on the road in 10 years, we'll apply the given annual decrease rate of 1.9% to the initial count of 286 million.

First, let's calculate the decrease rate per year:

Decrease rate = 1.9% = 1.9/100 = 0.019

Next, we'll calculate the predicted count after 10 years using the formula for exponential decay:

Predicted count = Initial count * (1 - Decrease rate)^Number of years

Substituting the values:

Predicted count = 286 million * (1 - 0.019)^10

Calculating the value:

Predicted count ≈ 286 million * (0.981)^10

Rounding the answer to the nearest whole number:

Predicted count ≈ 286 million * 0.816

Predicted count ≈ 233,176,000

Step-by-step explanation:

To calculate the amount of wrapping paper needed to cover the package, we need to find the area of each face of the trapezoidal prism and add them together.

First, we can find the area of the trapezoidal front and back faces. The formula for the area of a trapezoid is:

Area = (a + b) / 2 * h

where a and b are the lengths of the parallel sides, and h is the height. For the front and back faces, we have:

Front/back area = ((6 + 12) / 2) * 15 = 135 square inches

Next, we can find the area of the top and bottom faces, which are rectangles. The formula for the area of a rectangle is:

Area = length * width

For the top and bottom faces, we have:

Top/bottom area = 4 * 12 = 48 square inches

Finally, we need to find the area of the two slanted faces. These faces are parallelograms, and the formula for the area of a parallelogram is:

Area = base * height

where the base is the distance between the two parallel sides, and the height is the perpendicular distance between the two parallel sides. For the slanted faces, we have:

Slanted face area = 1/2 * (12 + 4) * 10 = 80 square inches

Now we can add up all the areas to get the total amount of wrapping paper needed:

Total area = Front/back area + Top/bottom area + 2 * Slanted face area

Total area = 135 + 48 + 2 * 80

Total area = 343 square inches

Therefore, the minimum amount of wrapping paper needed to cover the package is 343 square inches.

Step-by-step explanation: I am doing this assignment right now, after i submit it i will reply with the answer. Edit: 15cm is correct.

The distance from point A (tangent point on clock) to point B (the hanger) is approximately 10 cm, based on the principles of right-angle triangles and Pythagorean theorem.

In this geometry problem, we're looking at a situation where a circular clock is hung by wires connected to a tangential point on the clock. By using right-angle triangle principles and the given radius of 15 cm from E to D, it''s key to recognize that triangle AED is a right triangle (since a radius perpendicular to a tangent at its point of contact forms a right angle).

So, the distance from A to E (the radius) is 15 cm. The distance from E to D is also a radius, hence is 15 cm as well. Now, by Pythagoras theorem for right triangle AED, the distance AD (the hypotenuse) is square root of (15^2 + 15^2), which is approximately 21.21 cm.

The distance BD from the top of the clock at point D to the hanger at point B is given as 10 cm. Since the clock is hanging from point B, this creates another right triangle ADB. The length from point A to B is found by subtracting BD (10 cm) from the hypotenuse AD (21.21 cm), which is roughly 11.21 cm. However, this option is not offered in the question, meaning a rounding must be made, so the answer is approximately 10 cm.
