Step-by-step explanation:

we know that

The perimeter of rectangle is equal to

P=2(L+W)

In this problem we have that

must be less than 150in., and the width is 28in

so

P=2(L+28)

2(L+28) < 150

divide by 2 both sides

L+28 < 150/2

L+28 < 75

solve for L (L is the height of the frame)

simplify

L+28 < 75

L < 75-28

L < 47 in

therefore

The height must be greater than 47 inches

Answer:

Therefore, the earliest time to take the next pill is after 10.85 hours and the latest time is before 15.14 hours have passed.

Step-by-step explanation:

The concentration of the drug in your system after ingesting 100.0 mg can be calculated using the formula:

C = D / V

where C is the concentration, D is the dose, and V is the volume of distribution (assumed to be constant).

At the initial time, t = 0, the concentration is:

C(0) = 100.0 mg / V

After one half-life, t = 16 hours, the concentration is:

C(16) = C(0) / 2 = 50.0 mg / V

After two half-lives, t = 32 hours, the concentration is:

C(32) = C(16) / 2 = 25.0 mg / V

After three half-lives, t = 48 hours, the concentration is:

C(48) = C(32) / 2 = 12.5 mg / V

To find the earliest and latest times to take the next 100.0 mg pill, we need to calculate the concentration at those times and make sure it stays between 20.0 mg and 140.0 mg.

Let's first find the earliest time at which the concentration drops below 20.0 mg.

20.0 mg / V = C(16 + x) = 50.0 mg / V / (2^(x/16))

Solving for x:

2^(x/16) = 50.0 / 20.0 = 2.5

x/16 = log2(2.5)

x = 16*log2(2.5) = 16*0.678 = 10.85

So the earliest time to take the next pill is after 10.85 hours.

Now let's find the latest time at which the concentration goes above 140.0 mg.

140.0 mg / V = C(16 + x) = 50.0 mg / V / (2^(x/16))

Solving for x:

2^(x/16) = 50.0 / 140.0 = 0.3571

x/16 = log2(0.3571)

x = 16*log2(0.3571) = -15.14

So the latest time to take the next pill is before 15.14 hours have passed.

Area of semicircle is 77.

What is semicircle?

A semicircle is defined as half circle formed by cutting the circle into two halves.

Given that;

Diameter of semicircle = 14

Radius of semicircle = 14/2 = 7

Now, Area of semicircle = 1/2 (πr²)

Substitute π = 22/7 and r = 7, we get;

Area of semicircle = 1/2 (πr²)

                             = 1/2 × (22/7) × 7 × 7

                             = 77

So, Area of semicircle is 77.

Answer: 803.84cm3

Step-by-step explanation:
The formula for finding the volume of a cylinder is πr2h.
In other words, the area of the top face's circle times the height.

To find the circle's area, we first find the radius of the circle. Since the diameter is 8cm, we divide by 2 to get the radius, which is 4cm.

4cm squared is 4cm x 4cm, which is 16cm. 16cm times 3.14 is 50.24cm squared.

Now, we have the area of the circle. 50.24cm squared!

The height is 16cm, so to find the cylinder, we times the area of the circle by the height of the cylinder! So,

16cm x 50.24cm squared = 803.84cm cubed.

The volume of the can of soup is 803.84cm cubed.

(a) The derivative of the function, dy/dx = (-399x⁶ - 380x³⁷y) / (9y⁸)

(b) The equation of the tangent line to the curve at (1, 1) is y = (-779/9)x + 778/9.

To find dy/dx, we differentiate both sides of the equation with respect to x using the chain rule and product rule as necessary:

d/dx (57x⁷) + d/dx (10x³⁸y) + d/dx (y⁹) = d/dx (68)

Simplifying each term using the power rule and the chain rule where appropriate, we get:

399x⁶ + 380x³⁷y + 9y⁸(dy/dx) = 0

Now, solving for dy/dx, we get:

dy/dx = (-399x⁶ - 380x³⁷y) / (9y⁸)

To find the equation of the tangent line to the curve at (1, 1), we first need to evaluate dy/dx at that point. Plugging in x = 1 and y = 1 into the expression for dy/dx, we get:

dy/dx = (-399 - 380) / 9 = -779/9

Now we can use the point-slope form of the equation of a line to find the tangent line. The point-slope form is:

y - y1 = m(x - x1)

where;

Plugging in m = -779/9, x1 = 1, and y1 = 1, we get:

y - 1 = (-779/9)(x - 1)

Simplifying, we get:

y = (-779/9)x + 778/9

If you have previous taxable wages of $102,000 and your current taxable wages are $1,100, your Social Security tax would be $6,324 for the previous wages and $68.20 for the current wages.

To calculate the Social Security tax, we need to know the tax rate for Social Security and the taxable wages. Let's assume the Social Security tax rate is 6.2% for both the employee and the employer.

Given that your taxable wages for Social Security purposes are $1,100, and your previous taxable wages are $102,000, we can determine the Social Security tax amount.

First, we need to calculate the Social Security tax on the previous taxable wages of $102,000. Multiply $102,000 by 6.2% (0.062) to find the Social Security tax for that amount:

Social Security tax = $102,000 x 0.062 = $6,324

Next, we calculate the Social Security tax on the current taxable wages of $1,100. Multiply $1,100 by 6.2% to find the tax amount:

Social Security tax = $1,100 x 0.062 = $68.20

Therefore, if you have previous taxable wages of $102,000 and your current taxable wages are $1,100, your Social Security tax would be $6,324 for the previous wages and $68.20 for the current wages.

Step-by-step explanation:

applying the formula for Time interms of speed and distance

Traveling from Earth to Mars is approximately 9.249626 x 10^7 km farther than traveling from Earth to the moon.

Earth to Mars is compared to traveling from Earth to the moon, we need to calculate the difference between the distances.

The distance from Earth to the moon is approximately 3.74 x 10^5 km.

The distance from Earth to Mars is approximately 9.25 x 10^7 km.

To find the difference, we subtract the distance to the moon from the distance to Mars:

9.25 x 10^7 km - 3.74 x 10^5 km

To subtract these numbers, we need to make sure the exponents are the same. We can rewrite the distance to the moon in scientific notation with the same exponent as the distance to Mars:

3.74 x 10^5 km = 0.374 x 10^6 km (since 0.374 = 3.74 x 10^5 / 10^6)

Now we can perform the subtraction:

9.25 x 10^7 km - 0.374 x 10^6 km = 9.25 x 10^7 km - 0.374 x 10^6 km

To subtract, we subtract the coefficients and keep the same exponent:

9.25 x 10^7 km - 0.374 x 10^6 km = 9.25 x 10^7 - 0.374 x 10^6 km

Simplifying the subtraction:

9.25 x 10^7 - 0.374 x 10^6 km = 9.249626 x 10^7 km

Therefore, traveling from Earth to Mars is approximately 9.249626 x 10^7 km farther than traveling from Earth to the moon.

Scientific notation is a convenient way to express very large or very small numbers. It consists of a coefficient (a number between 1 and 10) multiplied by a power of 10 (exponent). It allows us to write and manipulate such numbers in a compact and standardized form.

For expression  x+1= √19-x, the value of x is approximately 3.

What exactly are expressions?

In mathematics, an expression is a combination of symbols and operators that represents a quantity or a mathematical relationship. It can contain numbers, variables, operators, functions, and other mathematical symbols. Expressions are used to represent mathematical operations and relationships, and they can be evaluated or simplified using mathematical rules and properties. Examples of expressions include 3x + 2, (x + y) / (x - y), and sin(x) + cos(y).

Now,

Starting with the given equation:

x + 1 = √(19 - x)

We can begin by squaring both sides of the equation to eliminate the square root:

(x + 1)² = (√(19 - x))²

Simplifying the right-hand side:

(x + 1² = 19 - x

Expanding the left-hand side:

x² + 2x + 1 = 19 - x

Moving all the terms to one side:

x² + 3x - 18 = 0

Now we can solve this quadratic equation using the quadratic formula:

x = (-b ± √(b² - 4ac)) / 2a

where a = 1, b = 3, and c = -18:

x = (-3 ± √(3² - 4(1)(-18))) / 2(1)

x = (-3 ± √(81)) / 2

x = (-3 ± 9) / 2

This gives us two solutions:

x = 3 or x = -6

However, we must check both solutions to make sure they are valid in the original equation:

Checking x = 3:

x + 1 = √(19 - x)

3 + 1 = √(19 - 3)

4 = √16

4 = 4

This solution works.

Checking x = -6:

x + 1 = √(19 - x)

-6 + 1 = √(19 + 6)

-5 = √25

-5 ≠ 5

This solution does not work.

Therefore, the solution to the equation x + 1 = √(19 - x) is x = 3.

The equation of the line is y = x.

To find the equation of a line given its graph, you need to follow the steps below.

Step 1: Determine the slope of the line.The slope of the line can be determined using the formula: slope = rise/run or m = Δy/Δx. Rise is the change in the y-coordinates and run is the change in the x-coordinates.

Step 2: Determine the y-intercept of the line.The y-intercept is the point where the line intersects the y-axis. You can determine the y-intercept by looking at the point where the line crosses the y-axis on the graph. The y-intercept is denoted by the letter b.

Step 3: Write the equation of the lineThe equation of the line can be written in slope-intercept form, which is y = mx + b. The slope (m) and y-intercept (b) that were determined in steps 1 and 2 are used to substitute into this equation. Thus, the equation of the line becomes y = slope(x) + y-intercept.

Example:Let's say you are given the graph of a line below: .

Step 1: Determine the slope of the line.To determine the slope of the line, you need to choose two points on the line and calculate the rise and run. Let's choose the points (2, 1) and (4, 3). The rise is 2 (3 - 1) and the run is 2 (4 - 2). Therefore, the slope of the line is: m = 2/2 = 1.

Step 2: Determine the y-intercept of the lineThe line crosses the y-axis at the point (0, 0). Therefore, the y-intercept of the line is b = 0.

Step 3: Write the equation of the line.The equation of the line in slope-intercept form is y = mx + b. Substituting the slope and y-intercept into this equation gives: y = 1x + 0 or y = x.

The table of integrals can be a useful tool for simplifying the integration process, but it's important to have a solid understanding of calculus concepts in order to use it effectively.

The table of integrals is a tool used in calculus to simplify the process of finding antiderivatives. It lists various functions and their corresponding antiderivatives, or integrals.

To use the table of integrals, you first need to identify the function you are trying to integrate. Then, find a similar function in the table and use the corresponding antiderivative to solve your integral.

It's important to note that not all functions have a corresponding antiderivative listed in the table, and in those cases, other integration techniques must be used.

Additionally, it's always a good idea to double check your work and make sure the answer makes sense in the context of the original problem.
