Find the measure of angle D.
The measure of angle D is 25°
What is exterior angle theorem?Exterior angle theorem states that the measure of an exterior angle of a triangle is greater than either of the measures of the opposite interior angles.
Angle D and angle C are the two opposite angles.
Therefore;
40+9x-2 = 20x +5
38+9x = 20x +5
38-5 = 20-9x
11x = 33
divide both sides by 11
x = 33/11
x = 3
Therefore since angle D = 9x-2
substitute 3 for x
D = 9(3) - 2
D = 27 -2
D = 25°

The probability that Oscar gets heads and an even number is. The probability that Oscar gets tails and a prime number less than 4 is.
The probability of getting heads and an even number is 1/4, and the probability of getting tails and a prime number less than 4 is 1/6.
How to calculate coin toss probabilities?To solve this, we need to use the multiplication rule of probability, which states that the probability of two independent events occurring together is the product of their individual probabilities.
Let's first find the probability of getting heads and an even number. Since there are two equally likely outcomes when flipping a coin (heads or tails), and three equally likely outcomes when rolling a die (1, 2, 3, 4, 5, or 6), the probability of getting heads and an even number is:
P(heads and even) = P(heads) x P(even)
= 1/2 x 3/6
= 1/4
Next, let's find the probability of getting tails and a prime number less than 4. The prime numbers less than 4 are 2 and 3. So, the probability of getting tails and a prime number less than 4 is:
P(tails and prime) = P(tails) x P(prime)
= 1/2 x 2/6
= 1/6
Therefore, the probability that Oscar gets heads and an even number is 1/4, and the probability that Oscar gets tails and a prime number less than 4 is 1/6.

Find the derivative of the function f by using the rules of differentiation. f(x)=x^{0,9} f'(x) =
The derivative of the function f(x) = [tex]x^{0,9}[/tex] is f'(x) = [tex]0.9x^{-0.1}[/tex].
To find the derivative of f(x), we use the power rule of differentiation, which states that if f(x) = [tex]x^n[/tex], then f'(x) = [tex]nx^{(n-1)}[/tex].
In this case, we have f(x) = [tex]x^{0,9}[/tex]. Applying the power rule, we get:
f'(x) = [tex]0.9x^{0.9-1} = 0.9x^{-0.1}[/tex]
Note that [tex]x^{-0.1}[/tex] can be rewritten as [tex]1/x^{0.1}[/tex]. So we have:
f'(x) =[tex]0.9/x^{0.1}[/tex]
This expression tells us the slope of the tangent line to the curve of f(x) at any given point. For example, at x = 1, we have:
f'(1) = [tex]0.9/1^{0.1} = 0.9[/tex]
This means that the slope of the tangent line to the curve of f(x) at x = 1 is 0.9. As x increases or decreases from 1, the slope of the tangent line changes accordingly.

Tres amigos compran un pan Francés. Antoni comió 7/9 y Miguel
Eduardo comió 5/9. ¿Qué parte del pan Francés quedó para Fabian?
Answer:
Si Antoni comió 7/9 del pan francés y Miguel Eduardo comió 5/9, entonces la cantidad total de pan que comieron juntos es 7/9 + 5/9 = 12/9.
Esto significa que los tres amigos comieron 12/9 del pan, lo cual es equivalente a 4/3 del pan francés.
Para encontrar la cantidad de pan que quedó para Fabian, podemos restar 4/3 del pan francés de la cantidad total del pan francés, que es 1. Entonces:

Given that f is continuous on [1, 5] and differentiable on the interval (1,5), with f'(x) ≤ 23, for all x, and f(1) = 4. Find the largest possible value for f(5).
We are given that f is continuous on [1, 5], differentiable on (1, 5), and f'(x) ≤ 23 for all x. We want to find the largest possible value for f(5). the largest possible value for f(5) is found to be 96.
We can apply the Mean Value Theorem (MVT) here, which states that if a function is continuous on [a, b] and differentiable on (a, b), there exists a number c in the interval (a, b) such that f'(c) = (f(b) - f(a))/(b - a). In this case, a = 1, b = 5, and f(1) = 4.
Since f'(x) ≤ 23 for all x, we know that f'(c) ≤ 23. Plugging into the MVT equation, we have:
[tex]f'(c) = (f(5) - f(1))/(5 - 1) ≤ 23, f'(c) = (f(5) - 4)/4 ≤ 23[/tex]
To find the largest possible value for f(5), we assume f'(c) is equal to its maximum, 23: 23 = (f(5) - 4)/4. Solving for f(5), we get: f(5) = 4 + 4 * 23 = 4 + 92 = 96. So, the largest possible value for f(5) is 96.

) On January 2, 2019, Helmkamp Company purchased a $30,000 machine. It had an estimated useful life of 5 years and a residual value of $3,000. What is the amount of depreciation expense for 2020, the second year of the asset's life, using the double declining-balance method? (Round intermediary calculations to two decimal places and your final answer to the nearest dollar. )
The required answer is the double declining-balance method is $9,840.
To calculate the depreciation expense for 2020 using the double declining-balance method, we first need to determine the asset's straight-line depreciation rate. This is calculated by subtracting the residual value from the cost of the asset and dividing by the asset's useful life:
Depreciation base = $30,000 - $3,000 = $27,000
Annual depreciation expense (straight-line) = Depreciation base / Useful life = $27,000 / 5 = $5,400
Next, we need to determine the double declining-balance rate, which is twice the straight-line rate. Therefore:
Double declining-balance rate = 2 x (1 / Useful life) = 2 x (1 / 5) = 0.40 or 40%
Now we can calculate the depreciation expense for 2020:
Depreciation expense (2020) = Book value (beginning of year) x Double declining-balance rate
The book value at the beginning of 2020 would be the cost of the asset minus accumulated depreciation for the first year:
Book value (beginning of 2020) = $30,000 - ($5,400 x 1) = $24,600
As a result, depreciation increases during the initial year of possession and decreases thereafter.
Therefore:
Depreciation expense (2020) = $24,600 x 0.40 = $9,840
So the amount of depreciation expense for 2020, the second year of the asset's life,
using the double declining-balance method is $9,840.

These values (x4, y4) represent the coordinates of the missing vertex of Lana's square.
Find out the coordinates of the missing vertex?To determine the missing vertex of Lana's square, we need to know the location of the three given vertices. Let's assume that Lana plotted the vertices in a clockwise direction, starting from the top left.
If we denote the coordinates of the first vertex as (x1, y1), the second vertex as (x2, y2), and the third vertex as (x3, y3), then the coordinates of the missing vertex can be found as follows:
1. Calculate the distance between the first and second vertices:
d1 = sqrt((x2 - x1)^2 + (y2 - y1)^2)
2. Calculate the distance between the second and third vertices:
d2 = sqrt((x3 - x2)^2 + (y3 - y2)^2)
If the square is regular (i.e., all sides are of equal length), then d1 = d2. Otherwise, the shape is not a square.
3. Calculate the midpoint between the first and second vertices:
xm = (x1 + x2) / 2
ym = (y1 + y2) / 2
4. Calculate the vector that goes from the midpoint to the third vertex:

Calculate the costs of these home improvement and maintenance costs.
Annual real estate taxes on a property are $2046. Insurance premiums total $1236. Required flood insurance protection premiums are $380 annually. The county assesses an annual special assessment landfill fee of $125. Trash collection costs $65 quarterly. Annual homeowner's association is $720 for common area maintenance of the subdivision. The pool company charges $45 quarterly to maintain the pool. Ongoing termite and pest protection costs $39 monthly. How much should a buyer save each month to cover these fees?
Answer: To calculate the total amount a buyer should save each month to cover these fees, we need to add up all the costs and divide by 12 (the number of months in a year).
Annual real estate taxes = $2046
Insurance premiums = $1236
Flood insurance premiums = $380
Annual special assessment landfill fee = $125
Quarterly trash collection costs = $65 x 4 = $260
Annual homeowner's association fee = $720
Quarterly pool maintenance costs = $45 x 4 = $180
Monthly termite and pest protection costs = $39 x 12 = $468
Total annual costs = $2046 + $1236 + $380 + $125 + $260 + $720 + $180 + $468 = $5405
Total monthly costs = $5405 / 12 = $450.42
Therefore, a buyer should save $450.42 each month to cover these fees.

S= 1560cm
S= 570cm
S= 2700cm
S= 3000cm
The frog will travel a total distance of 1650 cm before she cannot jump anymore. None of the options given are correct.
To find the total distance the frog will travel, we need to add up the distances of all her jumps. Given that her first jump is her longest at 300 cm and her second jump is 270 cm, we can assume that each subsequent jump is shorter than the one before it.
The difference between the first jump and the second jump is 30 cm. So let's assume that the common difference between each jump is 30 cm. So the frog takes a total of 10 jumps before she cannot jump anymore.
The total distance the frog will travel is:
300 + 270 + (240 + 210 + 180 + 150 + 120 + 90 + 60 + 30) = 1650 cm

Explain why one-twelfth interest every month on an initial one pound will give you (1 + (1/12))¹² pounds at the end of the year
One-twelfth interest every month on an initial one pound will give (1 + (1/12))¹² pounds at the end of the year due to the compounding effect of interest.
How to find the formula for compound interest?The interest rate of investment of one-twelfth per month means that for every pound invested, one-twelfth of that amount will be added as interest at the end of the month. Therefore, at the end of the first month, the initial investment of one pound will earn an additional interest of (1/12) pound, making the total amount of money to be 1+(1/12) pounds.
At the end of the second month, the new amount of money will earn another one-twelfth of interest, which will be added to the previous total. Therefore, the new total amount of money will be (1+(1/12))+(1/12) = (1+(2/12)) pounds, which can be simplified to (1+(1/6)) pounds.
By the end of the twelfth month, the initial one pound investment will have earned twelve one-twelfth interests, which can be calculated as (1+(1/12)[tex])^12[/tex] pounds, using the formula for compound interest. This simplifies to (1+1/12[tex])^12[/tex] pounds or (1.0833[tex])^12[/tex] pounds, which is approximately equal to 2.613 pounds.
Therefore, an initial investment of one pound with a one-twelfth interest rate per month will earn a total of (1+(1/12)[tex])^12[/tex] pounds or approximately 2.613 pounds by the end of the year.

You are offered a couple of options in terms of investing the $15,000 you currently have. Explore the options and determine which one will get you $26,795 the fastest. Bank 'A' provides a 5. 45% interest rate, compounding continuously, how long will it take you, in years, if you invest $15,000 to make enough to buy the car? (round your answer to the nearest tenth) Bank "B" provides a 5. 75% interest rate, compounding monthly, how long will it take you, in years, if you invest $15,000 to make enough to buy the car? (round your answer to the nearest tenth) *
The option of bank B investment will allow to reach goal of buying the car the fastest compare to bank A it will take approximately 8.4 years
Saved amount = $15,000
Value of the car = $26,795
Use the formula for compound interest to calculate the time it will take to reach $26,795 for each bank,
Bank A,
Initial investment ' P ' = $15,000
Annual interest rate ' r ' =5.45%
= 0.0545
compounded continuously 'n' = infinity
Target amount 'A' = $26,795
The formula for continuous compounding is,
A = P[tex]e^{rt}[/tex]
Substituting the values, we get,
⇒ 26,795 = 15,000 × [tex]e^{(0.0545t)}[/tex]
Solving for t, we get,
⇒ t = (log(26,795/15,000))/(0.0545)
≈ 9.4 years
It will take approximately 9.4 years to reach the target amount if we invest in Bank A.
Bank B,
Initial investment ' P ' = $15,000
Annual interest rate ' r ' =5.75%/12
= 0.00479 (monthly interest rate)
n = 12 compounded monthly
Target amount 'A' = $26,795
The formula for monthly compounding is,
A = [tex]P\times( 1+ r/n)^{nt}[/tex]
Substituting the values, we get,
26,795 = [tex]15,000 \times(1+0.00479/12)^{12t}[/tex]
Solving for t, we get,
t = (1/12) × (log(26,795/15,000))/(log(1+0.00479/12))

In scientific notation, a number is expressed as a coefficient multiplied by a power of 10. The coefficient is a number greater than or equal to 1 and less than 10, and the power of 10 indicates how many places the decimal point has been moved to create the coefficient.
In this problem, we are given the populations of the three states in scientific notation. Connecticut's population is given as 3.6 × 10⁶, which means that the coefficient is 3.6 and the power of 10 is 6. To convert this number to standard notation, we simply move the decimal point 6 places to the right to get 3,600,000. Similarly, New York's population is given as 1.947 × 10⁷, which means that the coefficient is 1.947 and the power of 10 is 7, and Rhode Island's population is given as 1.056 × 10⁶, which means that the coefficient is 1.056 and the power of 10 is 6.
To find the total population, we add the populations of the three states together:
Total population = Connecticut population + New York population + Rhode Island population
Total population = 3.6 × 10⁶ + 1.947 × 10⁷ + 1.056 × 10⁶
Total population = (3.6 + 19.47 + 1.056) × 10⁶
Total population = 24.126 × 10⁶
We can simplify this expression by multiplying the coefficient by 10⁶:
Total population = 24.126 × 10⁶ = 2.4126 × 10⁷

Ryan went shopping and purchased two shirts for $16 each, and a pair of sneakers that cost 2 1/2 times as much as a shirt. How much money did Ryan spend?
Answer:
Ryan spent $72 on his shopping trip.
Step-by-step explanation:
To find out how much money Ryan spent, we need to add up the cost of the shirts and the sneakers.
First, we know that Ryan purchased two shirts for $16 each. So we can find the total cost of the shirts by multiplying the cost per shirt by the number of shirts:
$16 per shirt x 2 shirts = $32So the total cost of the shirts is $32.
Next, we know that Ryan purchased a pair of sneakers that cost 2 1/2 times as much as a shirt. We can use this information to find the cost of the sneakers.
If the cost of a shirt is $16, then we can find the cost of the sneakers by multiplying $16 by 2 1/2:
$16 x 2 1/2 = $16 x 2.5 = $40So the cost of the sneakers is $40.
Finally, we can find the total cost of Ryan's shopping trip by adding up the cost of the shirts and the sneakers:
$32 + $40 = $72Therefore, Ryan spent $72 on his shopping trip.
Mr. ream mixes 12 cups of paint in a large bowl. he used the paint to fill 40 small dishes with 2 fluid ounces of paint each. how many cups of paint does mr. ream have left in the bowl
Mr. Ream has 7 cups of paint left in the bowl.
There are 12 cups of paint, which is equivalent to 192 fluid ounces of paint (1 cup = 16 fluid ounces). Mr. Ream filled 40 small dishes with 2 fluid ounces of paint each, for a total of 80 fluid ounces of paint used (40 x 2 = 80).
Therefore, Mr. Ream has 192 - 80 = 112 fluid ounces of paint left in the bowl.
To convert this to cups, we divide by 16 (1 cup = 16 fluid ounces):
112/16 = 7 cups
Therefore, Mr. Ream has 7 cups of paint left in the bowl.

Mia crosses a river when she drives from her house to the beach. The function d(t)=40|t-1. 25| shows Mia's distance from the river, d, in miles after t hours. The domain of the function is 0
The domain of the function is given as 0<t<3, which means that the time elapsed is between 0 and 3 hours. Mia's distance from the river after 2 hours of driving is 30 miles.
The given function is:
d(t) = 40|t-1.25|
Here, t represents the time elapsed in hours and d represents the distance from the river in miles.
To find Mia's distance from the river, we need to plug in values of t into the function.
For example, if t=2, then:
d(2) = 40|2-1.25|
d(2) = 40|0.75|
d(2) = 30
So Mia's distance from the river after 2 hours of driving is 30 miles.
Similarly, we can find Mia's distance from the river at other points in time.
To graph the function, we can plot points by choosing different values of t and finding the corresponding values of d. We can then connect these points to get a graph of the function.
Graph of the function d(t) = 40|t-1.25|
The graph shows that Mia starts at a distance of 40 miles from the river and then approaches it until she reaches the other side of the river, where her distance from the river is again 40 miles. The graph is symmetric about t=1.25, which means that Mia spends the same amount of time on either side of the river.
