As a daffodil grows, it increases in height by 3 inches every 2 days. If the daffodil plant starts at 1 inch on day one, what will the height be on day 2?
Answer: If the daffodil start at 1 inch on day one, and only 1 day has passed, it will grow half of what it would in 2 days because half of 2 is 1. So the current height 1 inch + how much it will grow in one day (1.5 inches) = the final height (2.5 inches) Hope this helps :D

$480, 15% interest, 1.5 years. Find the interest to the nearest cent for each principal, interest rate, and time.
The simple interest earned after 3 years on $500 at an interest rate of 6% is $90.
Simple interest is a type of interest that is calculated based only on the initial amount borrowed or invested, called the principal amount, and does not take into account any additional interest earned on the interest over time.
To find the simple interest earned on $500 at an interest rate of 6% after 3 years, we can use the formula:
Simple Interest = Principal x Rate x Time
Where
Principal = $500
Rate = 6% = 0.06 (in decimal form)
Time = 3 years
Plugging these values into the formula, we get
Simple Interest = $500 x 0.06 x 3
= $90

find the value of H for the parallellogram to the right
Answer:
h = 10 13/14 units
Step-by-step explanation:
You want the height from the side of length 14 of a parallelogram with side length 17 and height 9.
AreaThe area of a parallelogram is the same, no matter which side is used as the "base". This means ...
A = bh = 17(9) = 14(h)

To landscape his 70 ft by 60 ft backyard, Austin is planning first to put down a 4 inch layer of topsoil. He can buy bags of topsoil at $2.50 per 3-ft3 bag, with free delivery. Or he
can buy bulk topsoil for $22.00/yd, plus a $20 delivery fee. Which option is less expensive?
I need volume of soil, cost of bags and cost of bulk
Answer:
To calculate the volume of soil needed, we first convert the dimensions of the backyard to feet:
Length = 70 ft
Width = 60 ft
Depth = 4 in = 4/12 ft = 1/3 ft
Volume = Length x Width x Depth
Volume = 70 ft x 60 ft x (1/3) ft
Volume = 1400 ft³
Option 1: Bags of topsoil
Each bag of topsoil contains 3 ft³ of soil, so the number of bags needed is:
Number of bags = Volume / Bag size
Number of bags = 1400 ft³ / 3 ft³ per bag
Number of bags = 467 bags
The total cost of bags of topsoil is:
Cost = Number of bags x Cost per bag
Cost = 467 bags x $2.50 per bag
Cost = $1167.50
Option 2: Bulk topsoil
The volume of topsoil needed is 1400 ft³, which is equivalent to:
Volume = 1400 ft³ / 27 ft³ per yd³
Volume = 51.85 yd³ (rounded to two decimal places)
The cost of bulk topsoil is:
Cost = Volume x Cost per yd³ + Delivery fee
Cost = 51.85 yd³ x $22.00 per yd³ + $20.00 delivery fee
Cost = $1153.70
Therefore, buying bulk topsoil is less expensive than buying bags of topsoil. The cost of bulk topsoil is $1153.70, while the cost of bags of topsoil is $1167.50
Answer:
Bulk is less expensive
Step-by-step explanation:
First convert inches to feet: 4 in x 1 ft/12 in =0.333 ft
Volume of topsoil needed = 70 x 60 x 0.333 = 1400 ft³
Bagged topsoil: 1400 ft³ x $2.50/3 ft³ = $1166.67
Bulk: 1400 ft³ x 1 yd³/27 ft³ x $22.00/yd³ + $20 = $1160.74
Bulk is just a little cheaper

The opposite side of the right triangle (x) is approximately 6.888 inches long.
Right angle triangleTo solve this problem, we can use the trigonometric ratio for the sine function, which is opposite/hypotenuse. We have the hypotenuse as 12 inches and the opposite angle as 35 degrees, so we can set up the equation:
sin(35) = opposite/12
To solve for the opposite, we can multiply both sides by 12:
opposite = 12 * sin(35)
sin(35) as approximately 0.574:
opposite = 12 * 0.574
opposite ≈ 6.888
Therefore, the opposite side of the right triangle (x) is approximately 6.888 inches long.

Question 5
Karin has $83,555 in a retirement account right now. Suppose she deposits $3,000 this year and then increases that by 7.5% each subsequent year. The account earns 9.8%. Find her future account value after 20 years.
The solution of the given problem of percentage comes out to be Karin's future account value would therefore be about $313,425.67 after 20 years.
What are percentages?In statistics, a figure or metric that may be presented as a percentage or 100 is denoted by the abbreviation "a%". Other unusual spelling is "pct," "pct," and "pc." The percent symbol ("%") is the method that is most usually used for this.
Here,
Using the compound interest calculation, we can determine Karin's account worth in 20 years:
=> A = P(1 + r)ⁿ
P =$83,555 (current balance), as given.
(Annual interest rate) r = 9.8% = 0.098
20 years, n
Let's use the following formula to determine the future account worth for each year:
Year 1: P = $83,555 (balance as of now)
(Annual interest rate) r = 9.8% = 0.098
Given that this is the first year, n equals 1.
=> A = $83,555(1 + 0.098)¹
=> A = $83,555(1.098)
=>A = $91,785.09
Year 2: P = $6,225 (current balance after deposit) = $3,000 + $3,225.
(Annual interest rate) r = 9.8% = 0.098
n = 1 year
=> A = $6,225(1 + 0.098)¹
=> A = $6,225(1.098)
=> A = $6,834.44
After 20 years, the current balance is
=> P = $12,873.51 + (20 - 1)($3,000 + 7.5% of $3,000)
= $12,873.51 + $71,132.10 = $83,005.61.
The yearly interest rate is 9.8%, or 0.098.
20 years, n
=> A = $83,005.61(1 + 0.098)²⁰
=> A = $83,005.61(3.778)
=> A = $313,425.67
Karin's future account value would therefore be about $313,425.67 after 20 years.

What if the dimension of the original rectangle in Exercise 1 had been multipled by 1/2? How would the area have been affected
If the dimensions of a rectangle are multiplied by 1/2, its area will be multiplied by 1/4, which means the new area will be one-fourth of the original area.
What is the area of the rectangle?To find the area of a rectangle, we multiply the length of the rectangle by the width of the rectangle.
According to the given information:The area of a rectangle is calculated by multiplying its length and width. If the dimensions of a rectangle are multiplied by a factor of k, then the new area of the rectangle is equal to k times the original area.
In this case, the dimensions of the original rectangle are multiplied by 1/2, which means that the new length and width of the rectangle are 1/2 times the original length and width. Therefore, the new area of the rectangle is equal to (1/2) times the original length multiplied by (1/2) times the original width. This can be simplified to 1/4 times the original area. Therefore, the area of the new rectangle is one-fourth of the area of the original rectangle.
Therefore, If the dimensions of a rectangle are multiplied by 1/2, its area will be multiplied by 1/4, which means the new area will be one-fourth of the original area.

wo random samples of earnings of professional golfers were selected. one sample was taken from the professional golfers association, and the other was taken from the ladies professional golfers association. at , is there a difference in the means? the data are in thousands of dollars. use the critical value method with tables. pga lpga
in general, to perform a hypothesis test comparing the means of two independent samples using the critical value method, you would follow these steps:
State the null and alternative hypotheses. For example, the null hypothesis could be that there is no difference in means between the two populations (i.e., H0: µ1 - µ2 = 0), and the alternative hypothesis could be that there is a significant difference in means (i.e., Ha: µ1 - µ2 ≠ 0).
Determine the level of significance, α, which represents the probability of rejecting the null hypothesis when it is actually true. For example, if α = 0.05, then there is a 5% chance of making a Type I error (rejecting the null hypothesis when it is true).
Calculate the test statistic. The most common test statistic for comparing the means of two independent samples is the t-test. The formula for the t-test is:
t = (x1 - x2) / [s^2pooled/n1 + s^2pooled/n2]^0.5
where x1 and x2 are the sample means, s^2pooled is the pooled variance (calculated using the two sample variances and sample sizes), and n1 and n2 are the sample sizes.
Determine the critical value(s) from the t-distribution table based on the degrees of freedom (df) and level of significance (α). The degrees of freedom for a two-sample t-test is calculated as:
df = n1 + n2 - 2
Compare the test statistic to the critical value(s). If the absolute value of the test statistic is greater than the critical value(s), then reject the null hypothesis; otherwise, fail to reject the null hypothesis.

An event A will occur with probability 0.5. An event B will occur with probability 0.6. The probability that both A and B will occur is 0.1. If we know that B occurred, what is the probability that A occurred too? In other words, what is the conditional probability of A given B -- P(A|B)?
The conditional probability of A given B (P(A|B)) is 1/6, or approximately 0.167.
Conditional probability is the probability of an event occurring given that another event has already occurred.
It is denoted by P(A|B), where A and B are events, and P(A|B) represents the probability of event A occurring given that event B has already occurred
The formula for conditional probability is:
P(A|B) = P(A and B) / P(B)
To find the conditional probability of A given B (P(A|B)), we can use the formula
P(A|B) = P(A ∩ B) / P(B)
We are given:
P(A) = 0.5 (probability of event A occurring)
P(B) = 0.6 (probability of event B occurring)
P(A ∩ B) = 0.1 (probability of both A and B occurring)
Now, we can plug in the given values into the formula:
P(A|B) = 0.1 / 0.6
P(A|B) = 1/6.

Answer:
True
hope it helps :) !!!
Answer:
the answer is true, it's the objects net is the same as the surface area.
the given curve is rotated about the y-axis. find the area of the resulting surface. y = 1/4 x^2 − 1/2 ln(x), 3 ≤ x ≤ 5
To find the area of the resulting surface when the given curve y = 1/4x^2 - 1/2 ln(x) is rotated about the y-axis, we can use the Surface of Revolution formula:
Surface Area = 2 * pi * ∫[x * sqrt(1 + (dy/dx)^2)] dx from a to b
Here, a = 3 and b = 5.
First, we need to find the derivative of y with respect to x (dy/dx):
y = 1/4x^2 - 1/2 ln(x)
dy/dx = (1/4 * 2x) - (1/2 * 1/x) = x/2 - 1/(2x)
Now, let's plug this into the Surface of Revolution formula:
Surface Area = 2 * pi * ∫[x * sqrt(1 + (x/2 - 1/(2x))^2)] dx from 3 to 5
We will now integrate the expression within the brackets with respect to x from 3 to 5. This might be challenging to solve analytically, so we may need to use a numerical integration method or a calculator to find the exact value.
Once the integration is completed, you will obtain the surface area of the curve when rotated about the y-axis.

The graph of the exponential function across the interval is attached below
How to graph the exponential functionTo graph the function y = 3ˣ over the interval 1 ≤ x ≤ 2, you can follow these steps:
Choose a suitable scale for the x-axis and y-axis. Since the function grows rapidly, you may need to use a logarithmic scale on the y-axis to show the entire graph.
Plot some key points of the function. To do this, you can choose some values of x within the given interval and calculate the corresponding values of y. For example:
When x = 1, y = 3^1 = 3
When x = 1.5, y = 3^1.5 = 5.2
When x = 2, y = 3^2 = 9
Connect the plotted points with a smooth curve. Since the function is exponential, the curve will be a smooth upward curve that gets steeper and steeper as x increases.
Label the axes and add any necessary annotations or markings. For example, you may want to label the plotted points with their coordinates or add gridlines to help read off values from the graph.

However, the current pushes her at an angle of 28from her original path so that she comes ashore at point B 3mi from her destination at point CHow many minutes will her trip take? Round to the nearest minute.
Rounding to the nearest minute, the athlete's trip will take approximately 96 minutes.
Let's start by drawing a diagram to better visualize the situation:
A x D C
o-----x------------x

Here, point A is where the athlete starts, point B is where she comes ashore due to the current, point C is her intended destination on the shoreline, and point D is the point where she switches from rowing to running.
From the diagram, we can see that the distance AB is 3 miles, and the distance AC is 3 + 1/2 = 3.5 miles.
We can use the Pythagorean theorem to find the distance BC:
[tex]BC^2 = AB^2 + AC^2[/tex]
[tex]BC^2 = 3^2 + 3.5^2[/tex]
[tex]BC^2 = 12.25[/tex]
BC = sqrt(12.25)
BC = 3.5
So the distance the athlete needs to travel on foot is 3.5 miles.
Let's first calculate the time it takes for her to row to point D:
Time to row to D = Distance / Speed
Time to row to D = 1/2 / 2
Time to row to D = 1/4 hours
Next, let's calculate the time it takes for her to run from D to C:
Time to run to C = Distance / Speed
Time to run to C = 3.5 / 4
Time to run to C = 7/8 hours
Now, we need to find the time it takes her to travel from B to C.
We can use the law of sines to find the angle between AB and BC:
sin(28) / 3 = sin([tex]\theta[/tex]) / 3.5
sin(theta) = 3.5 * sin(28) / 3
sin(theta) = 0.5407
theta = arc sin(0.5407)
theta = 33.15 degrees
Therefore, the angle between AB and BC is approximately 33.15 degrees.
We can use this angle and the distance BC to find the distance the athlete actually traveled from B to C:
Distance traveled from B to C = BC * sin([tex]\theta[/tex])
Distance traveled from B to C = 3.5 * sin(33.15)
Distance traveled from B to C = 1.925 miles
Finally, we can calculate the total time of the trip:
Total time = Time to row to D + Time to run to C + Time to travel from B to C
Total time = 1/4 + 7/8 + (1.925 / 4)
Total time = 0.25 + 0.875 + 0.48125
Total time = 1.60625 hours
To convert this to minutes, we can multiply by 60:
Total time = 1.60625 * 60
Total time = 96.375 minutes.
