Given a formula for the balance in an account earning compound interest, you want the balance after 4 years when the principal invested is $500, the interest rate is 11%, and compounding occurs once per year.

For P=500, r=0.11, n=1, t=4 the formula is ...

  A = 500(1 +0.11/1)^(1·4)

  A = 500(1.11^4) = 500(1.51807041) ≈ 759.04

There will be $759.04 in the account after 4 years.

Step-by-step explanation:

The correct statement is: h(1) = h(2-1)

The statement "h(x) = h(2-x)" implies that the function h is symmetric about the line x = 1. Based on this symmetry, the following statements must be true:

h(1) = h(2-1) = h(1) - This means that the value of the function at x = 1 is equal to the value of the function at x = 1.

h'(1) = -h'(1) - This means that the derivative of the function at x = 1 is equal to the negative of the derivative of the function at x = 1.

Answer: Krista's  drawing would have a base length of 2 and 1/4 inches and a height of 7/8 inches

Step-by-step explanation: First you do 6 divided by 3 which is 2 then you make 3/4 in twelfths and you get 3/12, then you simplify that into 1/4. Then

you combine those and get a base length of 2 and 1/4 inches.

Next, you do 2 and 5/8 divided by 3. Since 3 is less than 2 your answer would have to be less than 1. What i would do is make 2 and 5/8 into a fraction, which would be 21/8. then to make it easiest you multiply that by 1/3. which would equal 21/24. and then you simplify by dividing that by 3. Which would give you 7/8, which would give you your answer.

So the final answer would be a base length of 2 and 1/4 inches and a height of 7/8 inches.

Answer:

4th answer is correct

Step-by-step explanation:

First, let us make x the subject.

\(\sf \frac{x+4}{4} =\frac{y+7}{7}\)

Use cross multiplication.

\(\sf 7(x+4)=4(y+7)\)

Solve the brackets.

\(\sf 7x+28=4y+28\)

Subtract 28 from both sides.

\(\sf 7x=4y+28-28\\\\\sf7x=4y\)

Divide both sides by 7.

\(\sf x=\frac{4y}{7}\)

Now let us find the value of x/4.

To find that, replace x with (4y/7).

Let us find it now.

\(\sf \frac{x}{4} =\frac{\frac{4y}{7} }{4} \\\\\sf \frac{x}{4} =\frac{4y}{7}*\frac{1}{4} \\\\\sf \frac{x}{4} =\frac{4y}{28}\\\\\sf \frac{x}{4} =\frac{y}{7}\)

To calculate the probability of a woman who owns 19 houses having fire damage in 1 of them in a year, we need to use the binomial distribution formula.

The binomial distribution is a probability distribution that describes the number of successes in a fixed number of independent trials. In this case, the number of successes is the number of houses that will be damaged by fire, and the trials are the 19 houses that the woman owns.

The formula for the binomial distribution is P(X=k) = (n choose k) * p^k * (1-p)^(n-k), where X is the number of successes, n is the number of trials, p is the probability of success, and k is the number of successes we want to find. In this case, n=19, p=0.01 (since 10 houses out of 1000 are expected to be damaged by fire in a year), and we want to find the probability of k=1 success. Plugging in these values, we get P(X=1) = (19 choose 1) * 0.01^1 * 0.99^18 ≈ 0.17959. Therefore, the probability that a woman who owns 19 houses will have fire damage in 1 of them in a year is approximately 0.17959, rounded to five decimal places.

In summary, we used the binomial distribution formula to calculate the probability of a woman who owns 19 houses having fire damage in 1 of them in a year, given that records indicate that 10 houses out of 1000 are expected to be damaged by fire in any year. The result was approximately 0.17959, which is the probability that we were looking for.

The volume of blood that passes through the cross-section per unit time is approximately 0.1532 cm^3/s.

Poiseuille's Law describes the flow of fluid through a cylindrical tube. It can be used to calculate the volume of blood that passes through a cross-section per unit time. The formula for Poiseuille's Law is as follows:

Q = (π * ΔP * r^4) / (8 * η * L)

Where:

Q is the volume flow rate,

ΔP is the pressure difference across the tube,

r is the radius of the tube,

η is the viscosity of the fluid, and

L is the length of the tube.

Given information:

Viscosity (η) = 0.0010

Radius (r) = 0.030 cm

Length (L) = 3 cm

Pressure difference (ΔP) = 1000 dynes/square cm

First, we need to convert the radius and length to meters, as the SI unit system is typically used in scientific calculations:

Radius (r) = 0.030 cm = 0.030 * 0.01 m = 0.0003 m

Length (L) = 3 cm = 3 * 0.01 m = 0.03 m

Now, we can calculate the volume flow rate (Q) using Poiseuille's Law:

Q = (π * ΔP * r^4) / (8 * η * L)

= (π * 1000 * (0.0003)^4) / (8 * 0.0010 * 0.03)

= (3.1416 * 1000 * 0.000000000027) / (0.024)

= 0.0036756 / 0.024

≈ 0.1532 cm^3/s

Therefore, the volume of blood that passes through the cross-section per unit time is approximately 0.1532 cm^3/s.

Step-by-step explanation:

The vector would point upwards and to the left, at an angle of 70 degrees from the -x axis. Sketching the vectors approximately to scale would confirm the directions and magnitudes of the components.

A) To find the x component, we use cosine of the angle: x = 50.0 N * cos(60 degrees) = 25 N. To find the y component, we use sine of the angle: y = 50.0 N * sin(60 degrees) = 43.3 N. The vector would point upwards and to the right, at an angle of 60 degrees from the +x axis.

B) To find the x component, we use cosine of the angle: x = 75 m/s * cos(5pi/6 rad) = -37.5 m/s. To find the y component, we use sine of the angle: y = 75 m/s * sin(5pi/6 rad) = 64.95 m/s. The vector would point downwards and to the left, at an angle of 150 degrees from the +x axis.

C) To find the x component, we use cosine of the angle: x = 254 lb * cos(325 degrees) = -206.5 lb. To find the y component, we use sine of the angle: y = 254 lb * sin(325 degrees) = -129.6 lb. The vector would point downwards and to the left, at an angle of 35 degrees from the -x axis.

D) To find the x component, we use cosine of the angle: x = 69 km * cos(1.1pi rad) = -22.87 km. To find the y component, we use sine of the angle: y = 69 km * sin(1.1pi rad) = 66.62 km. The vector would point upwards and to the left, at an angle of 70 degrees from the -x axis.

The approximate percent of the price increase is approximately 8.5%. To find the approximate percent of the price increase, we can use the following formula: Percent Increase = ((New Value - Old Value) / Old Value) * 100

To calculate the approximate percent of the price increase, we can follow these steps:

Determine the old value: In this case, the old value is the cost before the price increase, which is given as $240.0.

Determine the new value: The new value is the cost after the price increase, which is given as $260.40. Calculate the difference: Subtract the old value from the new value to find the increase in price. In this case, it is $260.40 - $240.0 = $20.40.

Calculate the percent increase: Divide the difference by the old value, then multiply by 100 to express it as a percentage. In this case, it is (20.40 / 240.0) * 100 ≈ 8.5%.

Therefore, the approximate percent of the price increase is approximately 8.5%. This means that the price increased by around 8.5% from its original value of $240.0 to the new value of $260.40.

Answer:

The surface area of a trapezoidal prism is the amount of area occupied by the surface of a trapezoidal prism. A trapezoidal prism is a three-dimensional solid that is made up of two trapezoids on opposite faces which are joined by four rectangles called the lateral faces. Like all three-dimensional shapes

Step-by-step explanation:

The area occupied by the surface of a trapezoidal prism is known as the surface area of a trapezoidal prism. Since the trapezoidal prism has a flat base, thus we can say that it has a total surface area and a curved surface area. The surface area of any three-dimensional geometrical shape is the sum of the surfaces of that enclosed solid which equals the areas of all of the faces. A trapezoidal prism has two trapezoidal faces four rectangular faces. Thus, the simple formula for calculating the surface area of a trapezoidal prism involves the area of the base, the perimeter of the base, and the slant height of any side of the prism. The surface area of any geometric figure is always measured in square units like cm2, m2, ft, or cubits2.
