Answer:

A) 18°

Step-by-step explanation:

To find the measure of the indicated angle, we can use trigonometric ratios.

Looking at the triangle, we can see that we are given the lengths of the two legs of the triangle, but not the hypotenuse. Since we are not given the hypotenuse, the sine and cosine ratios would not work since both of them require the length of the hypotenuse. We can use the tangent ratio, since it only requires the lengths of the two legs. Remember:

\(tan(?)=\frac{opposite}{adjacent}\)

From looking at the image, we can see that the length of the side opposite to the angle is 3, and the length of the side adjacent to the angle is 9. Thus, we can use 3 as out opposite and 9 as out adjacent:

\(tan(?)=\frac{3}{9}\)

Now we solve for ?. Lets take the inverse tan of both sides to get rid of the tan on the left side:

\(?=tan^{-1}(\frac{3}{9})\)

And we get:

? ≈ 18.4349488° ≈ 18°

So the answer would be 18°, or A.

An initial amount of $725,000, an APR of 6.25%, and a desired time frame of 22 years, the monthly withdrawal amount would be approximately $4,491.95.

To calculate the monthly withdrawal amount that would completely exhaust your savings in 22 years, we can use the present value of an ordinary annuity formula. The present value (PV) represents the initial amount you have, the interest rate per period (i) is the monthly interest rate, and the number of periods (n) is the total number of months.

Here's the step-by-step calculation:

Convert the APR to a monthly interest rate:

Monthly interest rate (i) = Annual interest rate / Number of compounding periods per year

i = 6.25% / 12 = 0.0625 / 12 = 0.00521 (rounded to 5 decimal places)

Determine the total number of periods:

Total number of periods (n) = Number of years * Number of compounding periods per year

n = 22 * 12 = 264

Use the present value of an ordinary annuity formula to calculate the monthly withdrawal amount (PMT):

PMT = PV / [(1 - (1 + i)^(-n)) / i]

In this case, PV = $725,000

PMT = $725,000 / [(1 - (1 + 0.00521)^(-264)) / 0.00521]

Calculate the monthly withdrawal amount using a financial calculator or spreadsheet software:

PMT ≈ $4,491.95 (rounded to the nearest cent)

Therefore, you can withdraw approximately $4,491.95 per month to completely exhaust your savings in 22 years assuming monthly compounding.

System of inequalities

We are given the graph where two lines represent the solution of a system of inequalities.

The solution is the double-shaded region of the graph.

We need to find the equation of the blue line and the red line and then convert them to inequalities.

Let's start with the blue line. We need to find two clear points through which it passes. These are (0,6) and (2,0). Now we write the equation of the line when knowing two points (the point-point form):

For the red line, the points are (0,0) and (2,2):

Now we have the equations of the lines, we must convert the equation to inequality by inserting one of these symbols instead of the equal sign:

> ≥ < ≤

For the blue line, the equation of the line is:

y = -3x + 6

Testing the origin (0,0):

0 = 0 + 6

0 = 6

To convert this to a true inequality we must replace the = for < or ≤

Since the blue line is solid, the points on the line belong to the solution, thus the first inequality is:

y ≤ -3x + 6

Now for the red line. The equation is

y = x. Let's test the point (2,1)

1 = 2

We must use the sign ≤ to make the expression true, thus the second inequality is:

y ≤ x

Thus, the system of inequalities is:

y ≤ -3x + 6

y ≤ x

The rotational kinetic energy of the thick-walled cylinder is 40 Joules.

The rotational kinetic energy of a rotating object can be calculated using the formula:

Rotational Kinetic Energy = \((1/2) * Moment of Inertia * Angular Speed^2.\)

To find the moment of inertia of a thick-walled cylinder, we need to consider its mass distribution and shape. For a thick-walled cylinder, the moment of inertia can be calculated as:

\(Moment of Inertia = (1/2) * m * (R_{outer}^2 + R_{inner}^2),\)

where m is the mass of the cylinder, R_outer is the outer radius, and R_inner is the inner radius.

In this case, the mass of the cylinder is 5 kg, the outer radius is 0.4 meters, and there is no mention of an inner radius. Assuming the cylinder is solid, we can consider the inner radius to be negligible.

Plugging in the values, the moment of inertia becomes:

Moment of Inertia =\((1/2) * 5 kg * (0.4^2) = 0.8 kg * m^2.\)

Now, we can calculate the rotational kinetic energy:

Rotational Kinetic Energy = \((1/2) * 0.8 kg * m^2 * (10 rad/s)^2 = 40 J.\)

Therefore, the rotational kinetic energy of the thick-walled cylinder is 40 Joules.

The scale drawing of the room is 10 inches long and 8 inches wide. If his actual room is 16 feet wide, the actual length of the room is 10 feet.

The scale of Harry's living room drawing is 10 inches long and 8 inches wide. Let's say the actual width of the room is 16 feet. We can use proportions to find the length of the actual room using the scale drawing.

The proportion of the length of the scale drawing to the actual length of the room is the same as the proportion of the width of the scale drawing to the actual width of the room.

Using this proportion, we can set up the equation:

10 inches / x = 8 inches / 16 feet

Simplifying this equation gives us:

10 inches / x = 8 inches / 192 inches

Cross-multiplying gives us:

10 inches * 192 inches = 8 inches * x

Solving for x gives us:

x = 120 inches or 10 feet

Answer: He bought 20 ice cream bars and 14 popsicle

Step-by-step explanation:

To solve this I used the elimination method, you could use substitution as well

Here are our two equations

x+y=34 Because the total number of ice creams bought must be given to 34 children and no more

2x+5y=128 because that is the cost for each ice cream and the amount he spent

For the elimination method we have to cancel out one of the variables, I decided to cancel out the x, so I multiplied the top equation by -2. So i got -2x-2y=-68

2x+5y=128 Then we get

3y=60 so

y=20

Now we can go back to the first equation and plug in y.

x+20=34

  -20  -20

x=14

(-3, 4)

Step-by-step explanation:

hey there,

< From the first equation, let's find x.

x + 3y = 9

x = 9-3y    (I hope you understand how that works )

Next, we can substitute our equation that equals to x into the second equation.

2x + y = -2

2(9-3y) + y = -2     (I substituted "x" in "2x" with (9-3y))

Now, let's solve.

2(9-3y) + y = -2

18 - 6y + y = -2

-5y = -20

y = 4

The coordinates of the relative maxima are (2, 13) and (-2, -13).

The coordinates of the relative minima are (0, -1).

The coordinates of the points of inflection are (-1, -10) and (1, 10).

There is no minimum. D. The coordinates of the points of inflection: A.

To determine the coordinates of the relative maxima, minima, and points of inflection, we need to analyze the behavior of the given function and its derivatives.

Let's start by finding the first and second derivatives of the function y = 3x^3 - 36x - 1.

Step-by-step explanation:

1. Find the first derivative (dy/dx) of the function:

  dy/dx = 9x^2 - 36

2. Set the first derivative equal to zero to find critical points:

  9x^2 - 36 = 0

  Solving for x, we get x = ±2

3. Determine the second derivative (d^2y/dx^2) of the function:

  d^2y/dx^2 = 18x

4. Evaluate the second derivative at the critical points to determine the concavity:

  d^2y/dx^2 evaluated at x = -2 is positive (+36)

  d^2y/dx^2 evaluated at x = 2 is positive (+36)

  Since the second derivative is positive at both critical points, we conclude that there are no points of inflection.

5. To find the relative maxima and minima, we can analyze the behavior of the first derivative and the concavity.

  At x = -2, the first derivative changes from negative to positive, indicating a relative minimum. The coordinates of the relative minimum are (-2, f(-2)).

  At x = 2, the first derivative changes from positive to negative, indicating a relative maximum. The coordinates of the relative maximum are (2, f(2)).

In summary, the coordinates of the relative maxima are (2, f(2)), there is no relative minimum, and there are no points of inflection.

Remi purchased approximately 150 pounds of pumpkins.

To find the number of pounds of pumpkins purchased by Remi, we can divide the total amount spent by the price per pound.

Let's assume that x represents the number of pounds of pumpkins purchased.

The total amount spent, $73.50, can be expressed as the product of the price per pound, $0.49, and the number of pounds purchased, x:

$73.50 = $0.49 × x

To solve for x, we divide both sides of the equation by $0.49:

x = $73.50 / $0.49 ≈ 150

Therefore, Remi purchased approximately 150 pounds of pumpkins.

By dividing the total amount spent by the price per pound, we found the quantity of pumpkins purchased.

In this case, Remi spent $73.50 and the price per pound was $0.49, resulting in the purchase of approximately 150 pounds of pumpkins. This information can be useful for budgeting, inventory management, and understanding consumer behavior at the local farm.
