Answer:
h = [tex]\frac{S-2\pi r^2}{2\pi r}[/tex]
Step-by-step explanation:
S = 2πr² + 2πrh ( subtract 2πr² from both sides )
S - 2πr² = 2πrh ( isolate h by dividing both sides by 2πr )
[tex]\frac{S-2\pi r^2}{2\pi r}[/tex] = h
A car rental company charges a service fee and then a daily rate when it rents out a car.
The total cost for the rental can be modelled by the following function.
C = 45d + 25
What statement is true about the rental company’s charges?
The statement that is true about the rental company’s charges is A. The deposit fee is $ 25 and the rental fee per day is $ 45.
How to find the true statement ?The total cost function is given as C = 45d + 25. This means that the slope is 45 and the y - intercept is 25.
This also means that the rental per day is $ 45 because the slope is the amount that the total cost changes by per day which must be the daily rental cost.
The $ 25 would be the cost that a person pays as a down payment when they rent the car because this amount does not change.

a fictional country has a population of 5 million people and a net immigration rate of 1 person per 1000 people. the population is only increasing due to immigration. how long will it take the country's population to double?
The time it takes for the country's population to double is 1000 years. The total population would be 10 million people.
How to calculate the population growth?We can calculate the population growth by
P = P₀ × r × t
Where
P = population growthP₀ = current populationr = growth raten = number of periodsSuppose that immigration is the only factor of population growth. We have
Net immigration rate, i = r = 1/1000The current population, P₀ = 5 million peopleFind the time that takes the country's population to double!
To make the country's population double, the population growth should be also 5 million people.
The formula would be
5,000,000 = 5,000,000 × 1/000 × t
t = 1,000/1
t = 1,000 years
Hence, the country's population will be double after 1,000 years.

Claire has no more than $45 to spend on a new dress. If x represents the amount Claire can spend, which inequality represents the possible prices of the new dress?
The possible prices of the new dress must be any value less than or equal to $45.
In mathematics, "inequality" refers to a relationship between two expressions or values that is not equal to each other. Therefore, inequality emerges from a lack of balance.
The equation-like form of the formula 5x 4 > 2x + 3 has an arrowhead in place of the equals sign. It is an illustration of inequity. This shows that the left half, 5x 4, is bigger than the right part, 2x + 3. Finding the x numbers for which the inequality holds true is what we are most interested in.
Start with the inequality x ≤ 45
This inequality states that x must be less than or equal to 45.
Therefore, the possible prices of the new dress must be any value less than or equal to $45.

The simplification of qr⁻⁴s⁰q⁻⁸r⁻¹s⁰q⁻¹rs⁹ using positive exponent is expressed as [tex]$ \frac{s^9}{q^8r^4}[/tex]
What is a positive exponent?A positive exponent indicates that the base should be multiplied by that many.
An exponent's sign indicates how many times to multiply or divide a base number. A negative exponent indicates the opposite. Negative exponents like xn can be rewritten as 1 / rs. As an illustration, qr^-4 s^6 q ^-8 s^6 q^-1 rs^6
The Power Rule for Exponents is a further exponent rule that follows from this. You multiply the exponents while keeping the base constant to simplify a power of a power. As an illustration, b for any positive s^6 q ^-8 s^6 q^-1 rs^6 number x and integers q and s.
⇒ qr⁻⁴s⁰q⁻⁸r⁻¹s⁰q⁻¹rs⁹
⇒ qr⁻⁴ × 1q⁻⁸r⁻¹×1q⁻¹rs⁹
⇒ qr⁻⁴ × 1q⁻⁸r⁻¹×1q⁻¹rs⁹
⇒ qr⁻⁸ × r⁻⁴ × s⁹
[tex]$ \Rightarrow \frac{1}{q^8} \times \frac{1}{r^4} \times s^9[/tex]

A desk is on sale for $480 , which is 50% of the regular price.
What is the regular price?
Answer: $960
Step-by-step explanation:
Regular Price = x
x*0.5 = 480
x = 960
Answer:
$960
Step-by-step explanation:
Since 480 dollars is half (50%) of the regular price...
you can find the total price by dividing 480 by 0.50 (50%)
or multiplying 480 by 2. You end up getting an answer of $960.
the proportion of defective electronic items in a shipment has the beta distribution. find the probability that at least 30% of the items in the shipment are defective (round off to second decimal place).
The probability that at least 30% of the items in the shipment are defective is 0.7360.
The beta distribution with parameters (3,3) is the conjugate prior for the binomial distribution with a probability of success of p, where 0<p<1.
The binomial distribution is a probability distribution that describes the number of successes in a fixed number of Bernoulli trials. A Bernoulli trial is a random experiment with two possible outcomes: success or failure. In the context of the problem you presented, success would be a defective item, and failure would be a non-defective item.
To find the probability that at least 30% of the items in the shipment are defective, we can use the cumulative distribution function (CDF) of the beta distribution. The CDF of the beta distribution is given by:
F(x;a,b) = (x^(a-1) * (1-x)^(b-1)) / B(a,b)
where x is the proportion of defective items, a and b are the shape parameters, and B(a,b) is the beta function.
We want to find P(X >= 0.3) where X is the proportion of defective items. Substituting the values for a, b, and x we get
P(X >= 0.3) = 1 - P(X < 0.3)
= 1 - F(0.3;3,3)
= 1 - ((0.3^(3-1) * (1-0.3)^(3-1)) / B(3,3))
= 1 - ((0.3^2 * 0.7^2) / (1/6))
= 1 - ((0.09 * 0.49) / (1/6))
= 1 - (0.044/0.1666)
= 1 - 0.2640
= 0.7360
Therefore, The probability that at least 30% of the items in the shipment are defective is 0.7360.

We know that when we talk about population growth, we are talking about the increase in the population of the species and this can be regarded as a kind of an exponential growth problem.
We know that we can write;
P = Poe^-rt
P = population at time t
Po = initial population
r = population growth rate
t = time taken
Then we have that at the said time, P = 1/4Po
Hence;
1/4Po = Poe^-0.365t
1/4 = e^-0.365t

Scale model A toy manufacturer sells a 0.9-m tall model of the CN Tower. The
model casts a shadow 0.2 m long. At the same time of day, the CN Tower casts a
shadow 123.3 m long. Find the height of the CN Tower, to the nearest metre.
Include a diagram in your explanation.
The height of the CN tower found using the trigonometric function to the nearest metre is 555m.
What are the different trigonometric functions?
Trigonometric functions are used to determine the relationship between
angles and sides of a triangle.
The basic functions are sine, cosine and tangent.
sine = perpendicular/hypotenuse
cosine = base/hypotenuse
tangent = perpendicular/base
From the figure, we can see the right-angled triangles made by both the model and real CN towers.
Since the shadow is cast at the same time of the day, we can say that the angles θ and Φ formed are the same angles.
So from the figure,
tan θ = tan Φ
0.9/0.2 = h/ 123.3
h = 554.85 m
Therefore the height of the CN Tower to the nearest metre is 555m.

She would be doing 9 hours of studying per day and 6 hours of other activities. This is because 15 hours divided by 9 hours of studying and 6 hours of other activities would equal the same amount of time allocated to each activity.
The amount of studying she is going to do per day is 9 hours, and the amount of other activities she is going to do per day is 6 hours. This means that she will be dedicating roughly 60% of her waking hours to studying and 40% to other activities. This is a good balance between the two activities, and it will ensure that she is able to adequately focus on both her studies and other activities.

For the given distance the time taken for the company plan to replace the machine in order to receive this trade in value is 4 years.
The term called distance is defined as the two points lie on the same horizontal or same vertical line and it is the distance can be found by subtracting the coordinates that are not the same.
Here we have know that the company buys a digital scanner for $12,000 the value of the scanner is $12,000 (1-n/5) after n years.
And here we also know that the company has budget to replace the scanner when the trade-in value is 2400.
By Using the given expression for the value of scanner after n years, we equate it to $2400 and solve for n is written as,
=> 12000 (1 - n/5) = 2400
When we simplify this one then we get,
